Mutations

Mutations, introduced in the Foundry Update, are passive modifiers that replace the Stat-based secondary effects from the Brutal Update. They are obtained between levels from Guillain.

Most mutations are not initially available. To unlock them, one must bring the mutations' blueprints to the Collector, then spend the required Cells.

Mechanics

The player can only have a certain number of mutations at once. Each area cleared in a run allows one more mutation, up to a total of 3 (unless in custom mode, where many more can be picked). However, the player can spend gold between levels to remove all current mutations, allowing a new choice of mutations to replace the old set. The price to do this starts at 1,000 and doubles with each reset, until the cost reaches 8,000 gold, at which point it will stop increasing.

Most mutations are associated with and scale their benefits with a specific stat. That is, mutations' base damage and/or healing magnitudes are multiplied by 1.15^n-1, where n is the current level of the appropriate stat, rounded to produce the final amount.

For example, if a Brutality mutation provides an extra 90 base DPS and the player's Brutality is 2, the final extra DPS is 90 × 1.15^2-1 = 90 × 1.15 = 103.5 ≈ 104). Note that damage and DPS bonuses from mutations are not affected by gear-specific damage bonuses or Affixes.

Colorless mutations have fixed benefits unaffected by Stats, except for Instinct of the Master of Arms.

As of v1.9, skills can no longer be used to activate mutations that lower their cooldowns when killing enemies, such as 'Hunter's Instinct', but will still activate ones like 'Heart of Ice' or 'Instinct of the Master of Arms', as they are not activated when killing enemies.

Colorless Mutations

Icon	Name	Description	Location	Unlock cost	Notes

	Ygdar Orus Li Ox	Saves you ONE TIME if you die prematurely. Cannot be dropped once picked up.	N/A (Always available, but only obtainable after exiting the Prisoners' Quarters and before entering either second stage. It can be re-obtained immediately after resetting mutations.)	N/A	Upon taking lethal damage which does not trigger sudden death prevention, freezes nearby enemies, returns you to 25% of maximum health, cleanses accumulated malaise and destroys itself. Once used, you cannot take another mutation in its place, locking this mutation slot for the rest of the run. Does not protect against death by curse. If the heart icon is red, the mutation is active; a rotten heart icon means it was used.
	Recovery	Time available to recover your health after a hit is multiplied by 2.	Conjunctivius (6th kill)	50	Rally health now drains 0.16 seconds (usually 0.08) after taking damage, at a rate of 15% of maximum health per second (usually 30% maximum health/s).
	Emergency Triage	Health potions only restore 45% HP but their use speed is increased by 300% and it completely protects you for 3 sec.	The Time Keeper (8th kill)	100	Before the Baguette Update, did not reduce the amount flasks healed. Using it with Extended Healing will make the effects merge: 65% healing spread over 15 seconds, scaling damage boost from Extended, elites have a chance to heal some malaise, use speed is 300% faster and it protects you for 3 seconds.
	Velocity	Running speed duration bonus (for kill combo) multiplied by 3.	The Time Keeper (5th kill)	50	Base duration of the speed bonus is 10 seconds.
	Dead Inside	+50% HP. Food no longer heals you. Your infection counter is increased by +6.	Lancer (4+ BSC; 1.7%)	100	Increased infection counter makes most of things that reduce infection by percentage heal different amount of infection than before: Flask charges heal 8 infection (was 5); Cough Syrups heal 4 (was 3); Food and Small Cough Syrups still heal 1 infection (was 1). Before v1.1, increased HP by 30% but allowed food to heal, and before v1.2, did not increase the infection counter. Before v1.9, this mutation was unlocked from the beginning of the game. Any save file that was started before this version will have the mutation already and thus will not require getting its blueprint from Lancers on 4+ BSC.
	Alienation	Reducing a curse restores 5% HP but increases the number of enemies required to lift the curse by 50%. Reducing a curse 5 times removes 2 Malaise.	The Concierge (7th kill)	50	Each instance of healing occurs over 2 seconds. Before v1.5, did not grant Malaise reduction for 5 kills while cursed, and before v1.1, did not require more kills to remove a curse and granted 10% HP for each enemy defeated. If combined with Acceptance, the latter scales on the modified curse value, rounded up.
	Acceptance	Removing a curse requires killing 50% less enemies. Consuming food curses you.	Requires 3+ BSC. First, gather all 3 Gardener's Keys in Promenade of the Condemned, then go through the Ramparts, the Graveyard, and the Forgotten Sepulcher for the Moonflower Keys. They are hidden in secret areas and locked behind doors which each require Gardener's Keys. In High Peak Castle, there is a secret area containing the blueprint in exchange for the Moonflower Keys.	200	Consuming food gives you 5 curse. Before v1.1, only reduced the amount of kills to remove curses. If combined with Alienation, the latter scales on the modified curse value, rounded up.
	Masochist	Trap damage is capped at 10% of your max HP. When hit by a trap your movement speed increases by 20% for 20 sec.	Deep pit in Slumbering Sanctuary, with spikes on the bottom and very thin platform at the middle of the pit. After you fall down, climb up walls until you see a secret passage with blueprint.	100	Independent of the usual speed buff. Before v1.1, only reduced damage by 80%.
	Disengagement	If your HP falls below 20%, a force field protects you for 5 sec. Can only be used every 120 sec.	Chamber in the start of Prisoners' Quarters which can only be accessed with the Homunculus Rune.	200	Triggers with Darkness and Poison damage, but does not protect against them.

Health mutations

In this table, you will find the heal value (in % of total HP) of the health mutations based on your Stats.

• Soldier Endurance increases your health by a % of your total HP, starting at 2% and capping at 25% with 19+ Brutality.
• Adrenalin heals a % of your total HP based on percentage multiplied by total damage of a single hit after dodging at the last second. Percentage provided by mutation starts at 0.0015% and is capped at 0.015% with 30+ Brutality.
• Frenzy heals a % of total HP based on percentage multiplied by total damage of a single hit if you are currently under speed buff. Percentage provided by mutation starts at 0.0012% and is capped at 0.008% with 37+ Brutality.
• What Doesn't Kill Me heals a percentage of your total HP after a parry, starting at 1% and capping at 3% with 24+ Survival.
• Necromancy heals a % of your total HP after killing an enemy, starting at 0.2% and capping at 1.7% with 33+ Survival.

Soldier Endurance's scaling follows the classic formula used for calculation of DPS (see DPS mutations), which is base value × 1.15^(Stats-1). On the other hand, Adrenalin, Frenzy, What Doesn't Kill Me and Necromancy scale based on slightly different formulas, which are base value × 1.085^(Stats-1), base value × 1.055^(Stats-1), base value × 1.05^(Stats-1) and base value × 1.07^(Stats-1), respectively.

DPS mutations

In this table, you will find the added DPS of mutations that add damage in certain conditions. All of these mutations scale with the formula [Base DPS] × 1.15^{(Stats - 1)}

For example, the Vengeance mutation's base DPS bonus is 90 and scales with Brutality. If you have 4 Brutality, the Vengeance mutation will add 90 × 1.15^(4-1) = 137 DPS to your attacks.

Other mutations

In this table, you will find the scaling of Melee, Berserker, Tainted Flask, Predator and Frostbite.

• Melee applies a slow down to enemies, which initially lasts for 0.2 second and caps at 0.8 second with 11+ Brutality.
• Berserker grants a % of damage reduction following a melee kill, which starts at 10% and caps at 60% with 14+ Brutality.
• Tainted Flask, on top of its DPS scaling, can grant a flask recharge if the player's potion is empty. This is triggered upon killing a certain number of Elites which decreases proportionally with the number of Brutality stats, starting at 12 Elites and capping at 4 Elites with 28+ Brutality.
• Predator grants short invisibility after killing an enemy with melee strike. The invisibility duration starts at 1 second and caps at 3.5 seconds with 23+ Tactics.
• Frostbite makes slow down also deal damage over time, with 32 base DPS.

For Melee, Berserker and Frostbite, the scaling formula is the same as for DPS mutations, that is [Base value] × 1.15^{(Stats - 1)}.

For Tainted Flask and Predator, the formula is instead [base value] × 0.96^{(Stats - 1)} and [base value] × 1.06^{(Stats - 1)}, respectively.
