Integrated Strategies #5: Sarkaz's Furnaceside Fables, often simply known as Integrated Strategies 5 (IS5) or Furnaceside Fables, is the fifth theme of the namesake roguelike game mode in Arknights.

Introduction

The voices of Revenants lead you away from reality.
A rite, a conversation.
The fantasies transcending the land is about to begin.

Synopsis

Main article: Sarkaz's Furnaceside Fables/Synopsis

Difficulty levels

• Face the Revenants is initially available, while Face the Revenants +1 and above are unlocked by completing a run in the preceding level (e.g. Face the Revenants +11 will be unlocked once the player completed a Face the Revenants +10 run).
• Buff increases the HP and ATK of enemies by the specified percentage on each floor (starting on 1F and increases on subsequent floors), using the following formula: a = (1 + b)c (a is the total buff; b is the buff percentage; c is the floor number).
  • The secret floor applies the buff at the floor when the player enters it, and do not increase the buff.
• Era determines the namesake's effectiveness.
• Burden determines the severity of Thoughts' Mental Burden exceeding the Threshold.
• Score is a modifier to the run's final score.

Nodes

	Operation Everyone has their weapons drawn. They're definitely not here to negotiate. Self-explanatory. Operations can be distinguished by the ISW-NO code. Certain Encounters can force the player into a unique operation distinguished by the ISW-SP code.
	Emergency Operation Some violence may well exceed your expectations, a very common occurrence. An ISW-NO operation with various handicaps, similar to that of Challenge Modes, and always awards a Collectible when cleared.
	Dreadful Foe Criminals, ruffians, and the damned... You're in trouble. An operation featuring I.S.-exclusive bosses, which can be distinguished with the ISW-DF code. The 3F Dreadful Foe awards a Super Rare Collectible (chosen from two options) when cleared, regardless of whether the boss is defeated or not. The 5F and 6F Dreadful Foes will end the run when cleared, but the former will not and instead acts like the 3F Dreadful Foe if the player has met the requirements to enter 6F. Despite being given the ISW-NO code, the 3F Dreadful Foe operations will never appear as (Emergency) Operations. Despite being referred to as Dreadful Foes on in-game texts, the node itself is classified as The Root. Dreadful Foes cannot be refreshed.
	Encounter New friends, old rivals... Strange encounters never age. Only scars stand the test of time. A random event.
	Wish Fulfilled There are many ways of making a wish, but the wish itself is almost always the same thing. Gives a Collectible of the player's choice.
	Safe House Nobody will bother you here, and there's plenty of food and water. No need to be so tense all the time. Gives a free reward of the player's choosing from three of the options listed below: +3 Elite Logistics Rations Voucher +3 (also ends the current Era once upgraded through Impressional Reconstruction) Increases the squad size by 1 (2 once upgraded through Impressional Reconstruction) +2 (+3 once upgraded through Impressional Reconstruction) Ideas Increases the Mental Burden Threshold by 2 (3 once upgraded through Impressional Reconstruction) Elite HR Dispatch Letter (once upgraded through Impressional Reconstruction)
	Downtime Recreation A little indulgence in life's simpler pleasures goes a long way in fighting the monotonous and the harrowing on your long road ahead. A mini-game where the player spend resources for additional resources or even Collectibles depending on the player's fortune.
	Rogue Trader Neither an ally nor an enemy. Some people like to sit on the fence. See Rogue Trader for more information.
	Prophecy 抉择就在眼前，结局早已注定。 The player makes a decision which influences the ending that would be reached. Prophecy cannot be refreshed.
	Idea Filter 形式的转变惟妙惟肖，令你以为自己分清了真假。 Applies a bonus by interpreting Thoughts, expending them in the process. See Sarkaz's Furnaceside Fables/Thoughts#Idea Filter for more information. Idea Filter always appear at specific points and cannot be refreshed.
	Face Off 同样的事情曾无数次发生在萨卡兹身上。 Can enter a "time trial" operation; see Addendum for more information.
	Lost and Found The void of helplessness will be filled by the joy and satisfaction of gain. Can exchange a Collectible with a different one. Not all Collectibles can be exchanged this way; see the infobox of the respective Collectible to determine whether it can be exchanged or not. The rarity of the new Collectible will match the old one. Note: Lost and Found will only appear after a certain Historical Reconstruction node is unlocked.
	Scout Someone will always have to take the first step, to show the way for those who come after. Can send off an Operator until the start of the next floor, at which the Operator will be automatically promoted (if not already) and the player receives rewards including Thoughts. Otherwise, the player will receive +2 . Keep in mind that the Operator cannot be included to the squad while they are away! Note: Scout will only appear after a certain Historical Reconstruction node is unlocked.
	Possibility 将梦想倾注于框架，细碎想法即可变作崭新规划。 Can enter the secret floor. Otherwise, the player will receive 1 Idea. Similar to Bosky Passages in Expeditioner's Joklumarkar, Possibilities have an uncommon chance of appearing compared to other events and may appear multiple times in one run. Possibility cannot be refreshed. Note: Possibilities will only appear after a certain Historical Reconstruction node is unlocked.
Addendum
Face Off information When a Face Off operation starts, the player needs to choose one of three groups of enemies that they will face by deploying a friendly unit in front of the corresponding enemy; during the group selection period, friendlies can be deployed for free. Each enemy group is denoted by a white, blue, and orange icon representing their difficulty, with white being easier and orange being harder. The player can refresh the enemy groups once per operation during the selection phase. Once the group is selected, the player can start the battle by clicking a button on the lower-right corner of the screen. It is impossible to select multiple groups of enemies with summons tied to some Operators. Enemies in Face Off operations do not deduct Life Points when entering a Protection Objective but the operation itself has a time limit; the operation ends when all enemies left the map (whether being defeated or entering Objectives) or the time runs out, with the rewards based on how many enemies the player had defeated.

Floors

1F – Genesis of Soulforge	The first sentence. Familiar temperature fades into the darkness, the reality is weakened at every turn. A Sudden Lack of Words It seems that you and your Sarkaz ancestors are equally attached to the warmth of the furnace. You have moved away from the illusions, and entered the dreamland.
2F – Wrought Iron Roots	The second line. The winding past connects to a future that has never been seen, and seeds of imagination burgeon in every pipe. A Sudden Lack of Words Each pipe seemed to branch into three, and then connect head to end, and you lost your words to describe them.
3F – Ashen Labyrinth	The third paragraph. Do you recognize this city//wreckage//palace//village? A Sudden Lack of Words That city//wreckage//palace//village has rejected you, it changes no more with your persuasion.
4F – Crossroad of Possibilities	The fourth section. Imaginations have reached perfection, Kazdel is complete yet empty. It greedily wants more, oblivious to the approaching boundaries. A Sudden Lack of Words You crossed the boundaries one after another, chose the Kazdels one after another, and they all accepted you.
5F – Boundary of Virtuality	The fifth chapter. To end is to split, to unify is to split, to stabilize is to split. Subverting the consensus is the only way to a new chapter. A Sudden Lack of Words "Come back."
6F – Shimmering Zenith	The sixth volume. The transcendental imagination beyond rebirth is right in front of you, unexpected yet reasonable. Accept the curse//blessing. A Sudden Lack of Words You fell before the truth. The resistance of the truth is so great, and you can only escape back to the truth.
Secret – Bizarre Fragments	Footnotes. Recorded history always longs for supplementary stories, just as the surface of water longs to be filled with reflections. A Sudden Lack of Words The surface of the water spread out as the molten thoughts rippled, and the boundaries were expanded once again.
Addendum
Excluding the first and last, nodes in 1F and 3F may have up to 3 branches, while those in 3F to 5F may have up to 4 branches. 1F consists of 4 nodes with a branch of 2 Operations as #1 and a Rogue Trader as #4. 2F consists of 5 nodes with Prophecy: Coronation as #1, a branch of 3 Operations or Encounters as #2, and an Idea Filter as #5. 3F consists of 6 nodes with a branch of 3 Operations or Encounters as #1, an Idea Filter as #5, and a Dreadful Foe as #6. The Dreadful Foe is randomly chosen between A Warrior Never Advises, Beneath the Crown, Decapitation, Devotion, Songless Courtyard, The Unstoppable, The Watching River, Veil of Possibility, and War For Survival. 4F consists of 6 nodes with a branch of 3 Operations or Encounters as #1, Wish Fulfilled (may be branched) as #5, and an Idea Filter as #6. 5F consists of 8 nodes with a branch of 3 Operations or Encounters as the first, Idea Filter (may be branched) as #6, Prophecy: The Last Page (may be branched) as #7, and a Dreadful Foe as #8. The Dreadful Foe is normally Urgent Teaching, but can be changed to Audience by choosing "Tell the King's names" on Prophecy: The Last Page (requires Pledge of Babel). 6F can only be entered by clearing the 5F Dreadful Foe while having Time and Light and consists of 5 nodes, always in the following order: Rogue Trader > Branch of 2 non-combat nodes > Branch of 2 combat nodes > Branch of 2 Idea Filters > Dreadful Foe: Civitas Sancta

Secret floor

To enter the secret floor, choose the option that requires the player to expend 2 Idea in a Possibility node and certain other events, or obtain either the “拱门” or “呼救” Collectible. The secret floor has one of the following layouts: Safe House > Rogue Trader > Branch of 2 combat nodes > Encounter: 温暖余韵 Branch of 2 Emergency Operations > Branch of 2 Prophecies > Dreadful Foe: Triumphant Return of Time Operation > Wish Fulfilled > Emergency Operation Face Off > Wish Fulfilled > Emergency Operation The (Emergency) Operations will be those that appears in the floor where the secret floor is entered and the next floor (e.g. if entered from 2F, the secret floor will have operations that would appear in 2F and 3F). The only exception to this is 6F, where the operations will be those on 5F and 6F instead. The player will receive one of the following Collectibles when entering the secret floor, which applies a handicap that is only effective on the secret floor. Each Collectible will only be given once per run if the secret floor is entered multiple times. 血税之谜: Friendly units and enemies have -35% (maximum) HP 结晶之谜: Friendly ground units have +600 DEF but will be Frozen for 15 seconds after deployment 猜疑之谜: Originium Ingot gains and Life Point losses are doubled 惧傲之谜: DP generation rate during operations halved but have +50 initial DP 预示之谜: Command Level EXP gain +20% but there will be more enemies that spawns a Terrorkaz when defeated 烙印之谜: Automatic SP recovery rate halved but friendly units have +30 initial SP 宁静之谜: Friendly units and enemies have -25% ATK 丝契之谜: Friendly units have +50 ASPD if there are no others in the surrounding 8 tiles, otherwise they lose 150 HP every second (which is non-lethal) Once the secret floor is cleared, the player will be taken back to the floor where they entered it and proceed into the node succeeding where the secret floor is entered from.
