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. 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 respec starts at 2,500 and greatly increases each time, up to 50,000.

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 1.15n-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 × 1.152-1 = 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.

Cooldown reduction mutations
In this table, you will find the effect value (in seconds) of the cooldown reduction mutations based on your Stats. Red and Green CDR mutations cap at 25 stats, Instinct of the Master of Arms caps at 24, and Hunter's Instinct caps at 19 Tactics.

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 capping at 25% with 19+ Brutality.
 * What Doesn't Kill Me heals a % of your total HP after a parry, capping at 15 Survival.
 * Necromancy heals a % of your total HP after killing an enemy, capping at 18 Survival.
 * All three follow the classic formula used for calculation of DPS (see DPS mutations), which is base value &times; 1.15Stat-1.

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] &times; 1.15^Stats - 1

For example, the Melee mutation's base DPS bonus is 120 and scales with Brutality. If you have 4 Brutality, the Melee mutation will add 120 &times; 1.15^4-1 = 183 DPS to your attacks.

Removed Mutations
