Expeditioner's Joklumarkar: Deep Investigation

A list of Expeditioner's Joklumarkar's Deep Explorations, named Deep Investigation (not to be confused with the same feature in Phantom & Crimson Solitaire).

Similar to Mizuki & Caerula Arbor's Deep Dives, Deep Investigations in Expeditioner's Joklumarkar are divided into four categories with similar environment changes and only the first Investigation of the category that is available at first; the rest being unlocked by completing the previous' Mission Objective. Unlike previous Deep Explorations however, Joklumarkar's Deep Investigations have the following differences:

• Quitting out or failing an (Emergency) Operation will not compromise the run, instead causing the player to have their Life Point cap reduced by 2 and skips the result screen (thus no rewards will be given).
• Instead of obtaining Command EXP to raise Command Level, the player obtains Recon Proficiency amidst an operation which raises Investigation Level with a much higher cap as shown in the table below.
  • Defeating normal enemies yield 10 Recon Proficiency, while elites yield 20 Proficiency and bosses yield 100 Proficiency.
  • Using Investigation Equipment (see below) also helps in gaining Recon Proficiency.
  • All Recon Proficiency accumulated during the operation will be accounted for towards the Investigation Level progress on the result screen. Emergency Operations are worth 50% more Proficiency, while Dreadful Foes are worth triple the Proficiency.
  • Raising the Investigation Level will also award a random Collectible (labeled as "Investigation Incentive") in addition to the resources.

• Investigation Equipment Collectibles are available; for more information, see Expeditioner's Joklumarkar/Collectibles/Investigation Equipment.
• Prophecies are absent and the 5F Dreadful Foe is either randomly chosen or specified depending on the Deep Investigation in question.
• Upon completing a Deep Investigation run, the player does not reach any of the three Joklumarkar endings; rather, The Fleetest of Light is shown instead with the following flavor text:

  “

  An incorrect deduction, a mistaken responsibility, an unnecessary sacrifice. You have found a way here for those who come afterwards, a secret that fate shall keep.

  ”

• Each content now has a record that can be unlocked by completing its Mission Objective.

Failed Expedition Record

"The expedition records will be handed over to Miss Arges, who will locate a Messenger to bring them back to Rhine Lab. She is watching me write these last few lines. Waiting to deal with the 'contamination' I caused." Rhine Lab Scientific Investigation Section. The recorder is currently entering the logbook of Jon, deceased Scientific Investigation member. Much of it is covered in black liquid, and she is struggling to decipher the text. The logbook chronicles the largest exploration of the endless icefields since the establishment of Scientific Investigation, and likely the last. More than a dozen explorers, including Director Maryam, perished in the sudden extreme weather. This diary was brought back by a Sami local. According to records, when she discovered Jon, the final survivor of the team, she only had time to watch him finish writing his suicide note. The recorder turns another page. "It's possible that she's not even looking at me. It's as if she's talking to the air above my head." After that, a large number of meaningless lines are left on the paper in ballpoint pen, crisscrossing several pages in a row. On the next intact page, there is only one line, completely unlike the previous text: "I'll never be able to see that future again."

Request for Help

"I write this letter with immense guilt upon learning that you are a former rescue squad member who has left Sami. The vast majority of people are indifferent to Sami, so I can only turn to you with this request." While at Rhodes Island, Qanipalaat receives a letter. The sender is a Columbian plant enthusiast. When he entered the Myrkwood to observe its ecology, he was unfortunately beset by a snowstorm. The vehicle he was driving was struck by a giant falling tree, and half the car was buried beneath the falling snow. Fortunately, a member of the rescue squad located him and blew the rock horn to call for help. Everyone worked hard to drag the injured man out of the car and transfer him to an open area nearby. But what happened next filled him with regrets. When the rescue squad members tried to use Arts to melt the ice and snow freezing the trunk of the vehicle, heat-inducing Arts triggered an explosion of the Originium fuel inside the vehicle, causing members of the rescue squad caught in the epicenter of the accident to suffer varying degrees of burns and show signs of Oripathy infection. Furthermore, two members were left disabled due to their lack of experience in dealing with such traumas. "We're the ones who brought these Originium machines over, yet we're unable to solve the problems they cause. If Sami's rescue team had more experience communicating with the outside, or if more disaster relief from other countries were willing to come here, we might've been better prepared to deal with these technology-related accidents. Maybe, that explosion would never have happened in the first place."

Premonition of the Past

No news from tranquil Sami. Čappat's intercity net is rarely updated, limited mostly to tourism inquiries from Columbian visitors. At the office Volvort Kochinski opened in this small town, two on-duty researchers are chatting about news that a newly-opened tourism route had caused the disappearance of several tour groups. Outside the window, a passing local stops to look inside. "Excuse me, are you looking for someone?" The researcher walks outside and greets her in broken Sami. She shakes her head and responds in Columbian: "There's nothing I want to see here," before turning and walking away. Two years later, the office left Čappat amidst a wave of departures. The work of sifting through data is coming to an end. The researcher breathes a sigh of a relief and lifts his head emotionally to look at the scenery of the desolate town street. The window spanning from floor to ceiling reflects his own uniform-clad figure. The figure looks back at him, but he sees another pair of eyes through the reflection. They are the lightly-colored eyes of a Sami woman.

Redeem Misfortune

The Cyclops had foreseen Eikthyrnir's sacrifice, but was still one step too late. She called out to the center of the battlefield, but the gravely wounded Snowpriest already lacked the strength to respond. Through all of this, what supported the hero of Sami in his fight against demonic corruption was a figure who had already passed away. When Eikthyrnir looked through his dimming eyes for the last time, at the land he had so fervently blessed, what kept his scarred body from being transfigured was the longing he held for his wife. However, it was not the memory of her itself, but rather the mantra he repeatedly told himself – "I must remember her." Remembering a soul that had been contaminated by the demons; a restless, nameless soul that became her last trace in this world. This lingering obsession dissipated into thin air with a vague call from the aether –– he realized that he could no longer remember the voice of his beloved.

Reverse Order

"Why did the people of the tribe give me a wooden shield instead of a staff when they announced my coming-of-age?" "Because you'd lose the shield." "Why do you want to go to the icefields of the northern reaches?" "Because I saw a door open at their end." "You don't make any sense. No wonder nobody wants to talk to you!" "Once destiny reveals its course, there is no distinction between cause and effect. However, if some things are destined to happen, I at least hope that I can change the order in which they arrive." "The order?" "...You're still a child, and I'd never invite you on this terribly long journey. However, are you determined to follow me anyway?" ...... The dying boy lies on the ground, recalling the fateful prophecy revealed to him by the Cyclops just moments ago. "You've chosen to bring your own death forward to this moment... a moment when the calamity that will swallow all of Sami has yet to occur. You were unable to die a hero's death, but at the very least, you were able to see the silver icefields in this lifetime."

Blind Prophet

Guided by the Cyclops, several forest shamans who once safeguarded the tribe are about to head north. Due to the recent series of strange phenomena, the tribe is in disarray. The well-learned Cyclops intervened just in time to inform them of the danger that lurked in the northern icefields. Meanwhile, the Cyclops promised that through her foresight, she would do her best to bring everyone back safe and sound. Thus, the tribe held a brief farewell ceremony for the shamans, adorning their staves with branches and leaves from the clan tree. But what they did not know was that the oracle herself had long been unable to see the true face of fate. She had raised her hand and pointed northward, only to grope around in the darkness in search of a possible path.

Unfamiliar Friend

Magallan rummaged through her equipment bag for quite some time, but couldn't find anything that would appeal to a Samifjod. Of course, Columbian gold certificates were right out, and so were experimental materials. And freeze-dried biscuits didn't seem to suit their tastes either. For the first time in Sami, she hadn't prepared very well. The hunter she was attempting to trade with shakes her head in dissatisfaction. This small group of hunters from outside the tribe were willing to lend aid to people lost in the deep forest, and did not mind escorting the team, even to faraway places, but Magallan is unable to offer them suitable recompense, and therefore has to leave in frustration. Half a day later, the hunters catch up to her. This time, they have a tall Sarkaz among them. The hunters inform them that the Cyclops had already traded with them, and paid even for Magallan's share. As such, they now travel together with a common goal. Magallan looks at the strange Sarkaz with astonishment. She seems to have a pair of eyes that can penetrate people's thoughts. Before Magallan can even voice her doubts, she replies. "Because I've seen you before." She answers tragically.

Divergent Start

There are no roads in the icefields, only a vast silvery-white expanse with no end in sight. But this is exactly the kind of long journey that Typhon enjoys. Arges gazes at the future, but Typhon's eyes must focus on the present – and the crisis in front of her. So many times, Typhon could only watch on in regret as the outline of her back gradually disappeared. But now, for the first time ever, she is traveling with Arges. Arges remains cautious and silent as usual, and does not explain her goals. But Typhon does not ask either. She doesn't need to. Just by observing, she can tell what the Cyclops had foreseen: they avoided the demons' footsteps, found an underground cave in time to escape the blizzard, and discovered geological structures that could serve as large natural shelters. When Arges's gaze suddenly stopped on the flower blooming suddenly upon the ice, Typhon looked at her expression and thought: this is what she had been searching for. And nobody understands her better. "Please help me send the flower back to Čappat, to a certain Columbian." And so, Arges makes a request of her. "Also, I need to find a group of lost southerners." But the scientific expedition team lost in the snowfield never returned to town, and the flower was never delivered. Typhon's footsteps would finally cease in the course of her most beloved journey. Through the "flower," the demons sensed her. The shadow had caught up to her. And this is where the collapse of all evolution begins.

Resolute Effort

Arges sits in the darkness away from the campfire, meditating alone. To be more precise, she is just thinking. The Cyclops had not entered a meditative state for a long time. It had been replaced by real dreams and nightmares, as well as the pain caused by her gradually worsening Oripathy. She has already accompanied Magallan into the icefields on several occasions, while also reaching out to encourage anyone and everyone to explore the icefields in search of information. Of course, she no longer saw the possibility in the Columbians she had once seen, and thus needed to seek out new possibilities to see a different outcome at the end of the icefields. However, she never saw the ring at the end of the icefield light up again. Contact with the outside world only brought her a clearer perception of the passage of time. The flourishing and withering of nature, and the fate of birth and old age, sickness and death, were no longer merely drops of water falling on a rock wall. What should she do to transplant the lifeline guided by fate? She is willing to do whatever it takes, but how? Arges lifts her head and takes a deep breath. For some inexplicable reason, she thinks that a certain tragedy she had foreseen is due to happen now. So she watches the dark shadows cast over the campfire where the explorers are sitting. She does not raise her voice to warn them, instead she simply gets up and leaves quietly.

Unmelted Snow

Santalla chases after the black footprints alone. She had heard of Ursus's Royal Guard. The arrogant people of Ursus who went as far as to declare the permanent damage they inflicted upon the land their "Dominion." Wheresoever their absurd ambitions might extend into Sami, Santalla must deny them, put a halt to them. It has become incredibly difficult to press forward. The footprints left by the enemy have become intermittent. Sometimes, they seem to cross a natural chasm in a single stride; sometimes, they seem to vanish into thin air. At other times, they seem to leave behind abnormal weather and dead beasts in their wake. Despite this, Santalla still catches up to the black shadow. When she finally catches a glimpse of its appearance, she finally understands her own fate as well. That corrupted monster could no longer be killed, only stopped at best. And the shaman, just like the resolute ice, would have her footsteps frozen here forever.

All to Deduction

The expedition is proceeding smoothly. Before the team embarked, the Cyclops had predicted with unparalleled accuracy the various troubles they would encounter. The only thing left for them to do was figure out how to carefully circumvent, or, as inexperienced amateurs, how to resolve the foreseen crises. In their opinion, this isn't particularly difficult. The squad successfully arrives at the hillside where the black hornbeast dwells, and sends the Messenger accompanying them back to report on the expedition's status. As the prophecy said, there is no day here, only starry nights. Everyone feels their heads spinning, either due to nerves or excitement. Perhaps the unique gemstone deposits she had foreseen are nearby. "When I set out, the people trying to stop me said she can't actually see the future at all." To lighten the atmosphere, one of the squad members jeered loudly, "If you ask me, those cowards were probably just afraid that she went crazy and got a bit TOO accurate." Hearing their voices, another expedition team emerges from the darkness of the valley. The explorers who had just arrived cheer even louder. They rush forward to embrace the first living people they've seen on their journey. But their laughter stops abruptly. Because what they face beneath those thick clothes are pitch-black voids. ...... The Messenger brings the report to Arges. Their whereabouts become a secret forever submerged in the shadows, their story becoming part of the Cyclops's prophecies. For a long time now, the only thing that's remained in the Cyclops' eye is a singular tragedy. All she can see is an apocalyptic ring.

Stray Signal

Rhodes Island continues to receive signals from the research outpost. Due to a certain decision, the landship docked near Sami half a month ago. Kal'tsit and the Doctor had already led a small team away towards the icefield. At first, the stationed operator thought it was intel sent back by the Rhodes Island team after successfully reaching the outpost. However, the intermittent signal did not match the voiceprint of any Rhodes Island operator, and the report contained a large amount of professional jargon, possibly involving confidential research results. The signal was quickly cut off. Over the next half month, every signal sent from the research outpost was dead silence. By the time they ceased entirely, Rhodes Island had received a total of seventy-five meaningless transmissions. A week after the signals stopped coming, the Rhodes Island team returned to the landship. Everyone kept silent about the situation in Sami and the icefield. Kal'tsit and the Doctor began dispatching Messengers to every corner of the land. They already know one thing for certain. Rhodes Island only received the signal by chance, because the user had found the sole method of transmitting their message. And despite the fact that research into the icefields has been suspended indefinitely, some are still encouraging outsiders to continue exploring through perilous secret passages, even delineating clear routes for these persistent explorers. In that research station, one visitor after another had carried out their final obsession before becoming completely corrupted. They had cried hopelessly and silently for Sami, through the only channel left to them.

Vision of Endings

There is no need to look back at where we came from. No matter how many warriors and explorers were buried by the snowstorm, no matter how many of their kind gave their lives to raise the veil against demonic encroachment, the Cyclopes and the outcast who ignored the order of morality had finally reached the end of the icefields. Now, the giant ring looms in front of them, just as prophesized, its awe-inspiring beauty completely incongruous with the icefield. It should have been a way out, a door to the future. It is the star the oracle had looked up to in her dreams countless times. It looked... full of hope. After countless sacrifices, after countless people apologizing and entrusting her with things in their dying breaths, she had no choice but to be hopeful about it. The oracle reaches out to the star. Nobody follows. Nobody cheers her feat. And no star falls to the earth. After a period of time no longer possessing any linear meaning, only the same deep void remains, both inside and outside the door.

Strategy

In general, Joklumarkar's Deep Investigations are not as difficult as the previous themes' Deep Explorations, in large part because the player can actually withdraw from an operation (with the sole exception of Dreadful Foes) without compromising the run if the situation does not work in one's favor, thus there is no shame in running away. However, Deep Investigations can be a bit more tricky to beat due to the radical changes over your average I.S. run.

• The usual Command EXP and level mechanic is replaced by Recon Proficiency and Investigation Level, the former of which is obtained from defeating enemies in an operation instead of clearing them (thus if the player retreats, no Recon Prof. will be awarded) and the latter of which has a much lower Hope payout but much higher cap and gives a Collectible in every level up to offset that. As such, if one want to achieve high Inv. Levels (especially because every single Deep Investigation's Mission Objective requires the player to be in at least Inv. Level 8 and meets a certain condition), go for the combat nodes over anything else!
  • As mentioned above, clearing Emergency Operations and Dreadful Foes give a higher Recon Prof. payout than normal Operations, so the former should be prioritized.
• Make good use of the Investigation Equipment! The Inv. Equipment will help the player a lot in gaining Recon Prof. and should not be underestimated.

Branching Paths – Observer's Vision
This Deep Investigation serves as the introduction for the rest, where the player just starts with a humble Hot Water Kettle; other than that, the run is identical to your run-in-the-mill Joklumarkar adventure aside from the 5F Dreadful Foe that is randomized. To complete the Mission Objective, the player must simply make their way to 3F and reach Investigation Level 8.

Chasing Fate

Once Observer's Vision is completed, this group of six Investigations will be available.

Hornblower's Vision

In this Deep Investigation, combat nodes appear more often than usual and the player is awarded with two Rec. Vouchers instead of the usual one upon clearing an operation, in addition to be given Inextinguishable Torch and Rock Horn to buff friendlies' offensive abilities by deploying them adjacent to each other. As for the 5F Dreadful Foe, it will be Lofty Silverfrost. To complete the Mission Objective, the player must have recruited four 4★ or higher Operators and reach Investigation Level 8.

Merchant's Vision

In this Deep Investigation, Rogue Traders will be entirely absent (even at the secret floor, which sometimes could contain nothing but Rogue Traders); because of this, the last node of 1F will be a Wish Fulfilled instead of Rogue Trader. All (Emergency) Operations will also contain two random Treasure Chests and the player is given Golden Chalice to buff friendly units' ASPD based on Originium Ingots in one's purse and Knight Lance Pro to increase the loot from Treasure Chests. As for the 5F Dreadful Foe, it will be Lofty Silverfrost. To complete the Mission Objective, the player must have accumulated 100 excluding those given at the start and reach Investigation Level 8.

Surveyor's Vision

In this Deep Investigation, there will be at least one Bosky Passage from 2F onward, which will increase the Anti-Interference Index by 1 when entered (so if the player choose to enter the secret floor, the Index spent is essentially refunded) and the player is given Scarred Amber to remove the Index cap and strengthen friendlies for every excess Index, and Northern Pioneer's Crutch to give 4 when entering a non-combat node with at least 4 Index. As for the 5F Dreadful Foe, it will be Sami's Entropy. To complete the Mission Objective, the player's Anti-Interference Index must have reached 7 at any point during the run as well as reaching Investigation Level 8.

Innocent's Vision

In this Deep Investigation, the Collapse Level will be increased upon accumulating 8 Collapse until C.L. 3, after which the C.L. will increase in every single Collapse! Furthermore, Emergency Operations will appear more often over regular Operations! The player is also given Amma's Affection and Ceremony Bell, and the 5F Dreadful Foe will be randomized. To complete the Mission Objective, the player must have entered 3 Lost and Found, and reach Investigation Level 8.

Guardian's Vision

In this Deep Investigation, 1F and 3F will be made up of two Safe Houses and a Rogue Trader, while 5F will be made up of a Rogue Trader, a Safe House, and Gardener as the Dreadful Foe. 2F and 4F, however, will be made up of three Operations whose map will be chosen from those that normally would become the 3F Dreadful Foe (and awards triple Recon Proficiency as the result)! To make up for all those, the player will start with 60 and 18 , allowing the player to recruit three 6★ Operators right off the bat and buy lots of stuff from the 1F Rogue Trader! To complete the Mission Objective, the player must have entered the sole Dreadful Foe – Gardener and reach Investigation Level 8. Because the Objective simply requires the player to enter a Dreadful Foe, not actually clearing it, the player can quit-out of Gardener as soon as it starts, compromising the run in the process yet the Objective will be completed regardless. This is also the case if the player decides to run the operation anyway but ended up failing.

Wanderer's Vision

In this Deep Investigation, the nodes in each floor will alternate between a combat node and a non-combat node, with the exception to the last one which will be pre-determined as usual while the 5F Dreadful Foe will be randomized. The player is also given Damaged Revolver Cylinder, Old Steam Armor, and Vieux Vanguard's Blade to greatly buff friendly units' ATK and DEF! To complete the Mission Objective, the player must have entered six combat nodes and reach Investigation Level 8.

Causal Abnormality

Once the Mission Objectives of three Chasing Fate Investigations are completed, this group of three Investigations will be available.

In Causal Abnormality Investigations, enemies have their HP and ATK increase as the player progresses around the same rate as in Braving Nature +7 and Dreadful Foe bosses having their HP, ATK, and DEF buffed, but the Recon Proficiency accrual is increased to make up for those.

Prisoner's Vision

In this Investigation, the player will be forced to pick the As Your Heart Desires initial Rec. Voucher option and the 5F Dreadful Foe will be Gardener! To offset the difficult situation, the player starts with 16 in addition to "Little Gran Faro", "Memories of The Shard", and Rainbow Jar because the player has to inevitably let some enemies waltz into Protection Objectives especially if one starts with little or no damage-dealing Operators, and earns 20% more Recon Proficiency. To complete the Mission Objective, the player must make their way into 4F and reach Investigation Level 8.

Tourist's Vision

In this Investigation, friendly units and enemies have their ASPD buffed, and the player earns 20% more Recon Proficiency, but Emergency Operations are more likely to show up over regular Operations. As for the 5F Dreadful Foe, it will be Lofty Silverfrost. The player is also given Royal Liqueur and Weave of Snow and Soil to capitalize on the fact that the buffed ASPD allows friendlies with offensive/defensive SP recovery skills to charge them up quickly! To complete the Mission Objective, the player must enter 4 Emergency Operations and reach Investigation Level 8.

Avenger's Vision

In this Investigation, instead of generating DP over time, the player has to defeat enemies to earn 5 DP each time, the nodes will usually be straightforward (not branching out) with each floor also having one extra node and the 5F Dreadful Foe being chosen at random, and the player earns 50% more Recon Proficiency. To make up for the fact that automatic DP generation is turned off, the player is given Doll House and Dreambind Castle Model to increase the initial DP by 40 — enough to set up your starting Operators early on, at least. To complete the Mission Objective, the player must have defeated 200 enemies and reach Investigation Level 8.

Dark Foresight

Once the Mission Objectives of one Causal Abnormality Investigation is completed, this group of three Investigations will be available.

Similar to Causal Abnormality Investigations, Dark Foresight Investigations have enemies growing stronger as the player progresses and Dreadful Foe bosses being buffed, with the former being in around the same rate as in Braving Nature +10! Of course, the Recon Proficiency accrual is increased by 50% to make up for the harsher handicap.

Fool's Vision

In this Investigation, the player will once again be forced to pick the As Your Heart Desires Rec. Voucher option and the Anti-Interference Index will go down by 2 upon entering a new floor! As in Prisoner's Vision previously though, the player starts with 16 to make up for the random start and will also be given "Blindness", Cannot's Mark, and Sprouted Stick to improve one's chances in this harsh condition. As for the 5F Dreadful Foe, it will be chosen at random. To complete the Mission Objective, the player must have obtained 12 Collectibles other than the aforementioned and reach Investigation Level 8.

Pariah's Vision

In this Investigation, the player will have to start with Life Prioritizing Squad and be given 3 random Foldartals, and the Recon Proficiency accrual will be increased by 5% each time the player declare Foldartals! However, aside from the last node which will be pre-determined as usual — the 5F Dreadful Foe will be chosen at random, 1F, 3F, and 5F will be entirely made up of (Emergency) Operations while 2F and 4F will consist of nothing but non-combat nodes! To complete the Mission Objective, the player must declare Foldartals 4 times and reach Investigation Level 8.

Prophet's Vision

In this Investigation, the player will have 12 Collapse right off the bat, causing them to start in Collapse Level 3! Furthermore, 1F to 4F will always start with a combat node; 1F will continue with a Safe House and ending with a Wish Fulfilled, 2F to 4F will have two non-combat nodes inserted in between, 2F and 4F will end with a Wish Fulfilled, and 3F will end with a Rogue Trader. As if those weren't enough, 5F will follow the same layout as in normal Joklumarkar runs (albeit without Prophecies as the second-to-last node) but will be made up of no less than 10 nodes in total including the Dreadful Foe, which will be chosen at random! To make up for this grueling condition though, the player is given Roundstone Altar, Slytooth, Forest Destroyer, and Three-Dimensional Art Display. To complete the Mission Objective, the player must clear 2 operations perfectly (i.e. without losing Life Points from leaking enemies) and reach Investigation Level 8.
