The Arknights Terra Wiki is a collaborative, community-maintained wiki. If you notice an issue, please consider making an edit, starting a discussion on the article's talk page, or reaching out via the Arknights Terra Wiki Discord.
This Reclamation Algorithm theme's updates in the Global server have been concluded. As such, the contents of this page and the related subpages have been archived.
New zones: Campervan, Deserted Town, Fortress, and Outpost.
New Raid types: Bandits, Brigands, and Stragglers.
The overworld is now divided into regions which are accessible once their respective Mountain Pass is cleared.
The overworld's weather is now affected by seasons which changes as days passed.
Changes:
The campaign no longer has a definite end; instead, the campaign is now divided into 3-day cycles with the player's progression being accounted for at the end of every cycle.
Operators no longer have Stamina which limits their usability; instead, they will be tired and unusable for the rest of the day after being brought into an operation.
Electrolyte Isotonics is replaced by Energy Drink which is required to enter combat zones.
Mountain Passes are now zones that blocks access to new regions until cleared; its previous role is now taken by Fortresses.
Encounters are now refreshed in every 2 cycles.
Resources in Resource Zones are now refreshed when a new season starts.
Wild Beasts in Hunting Zones are now refreshed in every cycle.
Bosses in combat zones now have their stats refreshed daily, but no longer respawns once defeated with the exception of those in No Man's Lands which respawns at the start of a new season.
New enemies:
Normal
Elite
Boss
Additional information:
Armored, Charging, and Flying Originium Slug are introduced in Expansion I.
"Liquid Shifter", Quicksand Beast, Rogue Burdenbeast, Thalebeast, and Vanillawing are introduced in Expansion II.
The campaign's difficulty can be changed in the main Tales Within the Sand menu, with changes immediately applying once selected.
Challenge Mode
Enjoy the challenge and pressure to survive
Technically the baseline mode due to the lack of handicaps. Strange Territory and Contention Reiteration is set to this mode irrespective of the current difficulty setting.
Same as Standard, but Raids no longer appear as days passed; this includes Elite Raids spawned by Fortresses, Bandits that would appear some time after taking over a Deserted Town, and Ameeri Armies that would appear at certain points in the campaign. However, Raids that are scripted to spawn as part of events and Sequences will spawn as normal.
Unlike the difficulty levels in Integrated Strategies, changing the difficulty does not affect the Prosperity Point accrual in any way, so feel free to switch the difficulty if one feels the campaign is too hard or easy!
After the Headquarters is upgraded to Level 3, the Logistics Support feature is enabled, which provides buffs to Operators of a certain class. The Logistics Operators can be assigned anytime, but their bonuses will only take effect from the next cycle and must be maintained at the cost of 1 for every 6 Logistics Operators[note 1] in every cycle; if the player's Energy Drink is insufficient, Logistics Support will not take effect.
Operators assigned to Logistics duty cannot participate in any other activities. Logistics Operators can be evacuated to partake in other activities again, but the buffs will be lost and they cannot be reassigned to Logistics duty for the remainder of the cycle.
The effectiveness of Logistics Support buffs are determined by the Support Points provided by each Logistics Operator for their respective class, which depends on their promotion and level:
Operators who are not yet or unable to be promoted to Elite 2 (including 1★ to 3★ Operators) provides 1 Support Point.
Operators who have been promoted to Elite 2 (includes 4★ and higher Operators) provides 2 Support Points, which increases to 3 upon reaching their respective Operator Module unlock requirement level:
Due to its indefinite nature, Tales Within the Sand features a save and load system that regularly records the player's campaign progress, allowing them to be reloaded anytime which can be useful to correct mistakes made during the campaign.
There are two save slots which records the first day of the last two cycles, done when the day starts with the newest one overwriting the oldest one. Saves can be loaded at any time during a campaign; the player will be prompted to load a save in the event they fail the Headquarters defense operation. Keep in mind that any progress up until a save is loaded will be lost, and if the player loads the oldest save, the newest one will be deleted.
After the newest save is loaded, the player must wait for 30 seconds before the oldest save can be loaded.
The save and load feature only affects the campaign's environment which includes inventory, built Constructs, zone exploration, Headquarters upgrade, Tech Tree, and score calculations; Tech Tree Points, Expansional Rewards' state, Formulating contents, and Contention Reiterations are unaffected.
The player can delete all of their saves; be warned that the process is irreversible and effectively terminates the campaign as the player will be returned to the main Tales Within the Sand menu and has to start a new campaign in a completely fresh state!! Fortunately, as stated above, Tech Tree Points are kept between campaigns, thus all spent Tech Tree Points will be refunded when a new campaign is started after deleting the previous campaign's saves.
Fight enemies in a repeatable operation like the usual Arknights gameplay.
Fortress
Elite Raids spawn from time to time in the Fortress (except in Peaceful Mode) until the Mobile Battle Tower within is destroyed. The Tower, however, will respawn at the start of a new cycle, with the exception of Taxed With a Choice.
Resource Zone
Materials can be gathered here, which will be refreshed at the start of a new season.
Hunting Zone
Main Provision ingredients can be gathered by hunting Wild Beasts here, which will respawn at the start of a new cycle.
A random event, like that of the namesake in Integrated Strategies. Encounters are refreshed at the start of every 2nd cycles.
Rally Point
Operators can be dispatched for missions which merits various rewards here, which expends one Act and some Energy Drinks; the dispatched Operators are also unusable until they return.
Base Camp
Various characters can be talked to here to start or advance Sequences. The Discovery Casket and Mail Box are also present here, where the player can accept Dynamic/Feral Strange Territory requests.
Unlike other zones, the Base Camp will always be present on a specific point and entering it does not expend Acts.
Mountain Pass
Blocks access to other regions until the Olden Keystone within is destroyed.
The player must have progressed through a certain point in the Main Sequence to be able to actually enter the Pass.
Deserted Town
Allows the player to dispatch Operators to obtain various resources in a similar manner to Rally Points, but without expending Acts, after being captured by destroying the Command Point within.
Each dispatch lasts for 6 days and a dispatch can be made every 3 days, meaning it is possible for two dispatches to be active at a time.
Except in Peaceful Mode, Bandits will appear and try to capture the Town from time to time; if this happens, the Town must be recaptured before the player can dispatch Operators again!
Raids must get through an Outpost before they can reach the Headquarters, which can be developed to aid in the HQ's defense. The higher the HQ's level, the stronger Outposts will be.
Good news: We'll reap a full harvest now if we work hard. Bad news: you have to help out too.
Drought
Resource-producing Constructs produce less resources;[note 2] <Dampsand> tiles dry up and become deployable tiles.
It's so dry we've gotten more nosebleeds than rainy days.
Monsoon
All Operators have Block -1 and Max HP -40%; <Splitmagma> tiles no longer deal damage
Heavy rain for days on end... who knew the Foehn wind could blow so much moisture our way? It's hard to get battle morale up in such extreme weather.
Additional information
A campaign always starts in the Lush season that lasts for 18 days, then cycles between the Monsoon, Drought, and Lush season in an infinite loop with each season lasting for 20 days.
The rain pours down a mix of dangerous elements absorbed from the earth, sparing not even the steel and iron machinery.
Thunderburst
Lightning strikes 1 random tile every 40 seconds, dealing 800 True damage to units (excluding Constructs) on the tile within a cross area; Crabbie Pumpie SP recovery +0.15/s
Its said that lightning tends to strike unlucky people...
Thunderstorm
Deals 20 Corrosion damage to all Operators every second; Lightning strikes 2 random tiles (range can overlap) every 40 seconds, dealing 800 True damage to units (excluding Constructs) on those tiles within a cross area; Crabbie Pumpie SP recovery +0.2/s
Thunder and lightning flash right before your eyes. To go out at this time, are you perhaps testing your luck against the elements?
Dizziness, blurred vision, confusion... the weather is too hot, please try to stay alert.
Bright Sun
Operators are afflicted with [Combustion] (receiving 50 Arts and Burn damage per second, does not stack and can be resisted) for 10s every 30s; All [Wild Beasts] Max HP -10%
Prolonged exposure to sunlight makes the ground hot enough to fry eggs, so be careful not to get sunburned while outside!
Scorching Sun
Operators are stunned for 10s every 50s; afflicted with [Combustion] (receiving 50 Arts and Burn damage per second, does not stack and can be resisted) for 20s every 30s; All [Wild Beasts] Max HP -15%
Weather that makes one wonder if this is what being baked feels like. If you stand outside for a while, you can feel your blood literally boiling.
Windblaze
Drought
Allied Operator Redeployment Time +50%; enemy Movement Speed -5%
Staying dehydrated for too long will deplete everyone's energy.
Sandstorm
A sandstorm starts blowing in a random direction when the mission begins, and allied units caught in the sandstorm will have -30 ASPD. Constructs and other Operators can block the sandstorm to negate the effects; enemy Movement Speed -10%
A storm in such a dry place makes sand and dust your biggest obstacle. Unless you have constructs or... someone else to cover you.
Habūb
Operator Redeployment Time +50%; A sandstorm starts blowing in a random direction when the mission begins, and allied units caught in the sandstorm will have -50 ASPD. Constructs and other Operators can block the sandstorm to negate the effects; enemy Movement Speed -15%
Being caught in such a fierce gale full of sand will not just hinder your movements!
Additional information
The Thunderburst/Thunderstorm lightning strike has an area-of-effect of the adjacent 2 tiles from the point of impact and briefly lifts the Fog of War on the affected area.
The Headquarters, Outposts, and Base Camp will always be Sunny.
Energy Drink which is required to enter combat zones.
Prosperity Point accrual in any way, so feel free to switch the difficulty if one feels the campaign is too hard or easy!
