Perks are passive items that modify and increase the abilities of the player in various ways. They are obtained between levels from Tutorial Knight . Most are not initially available, so in order to unlock them, one must bring their blueprints to the The Boy's Axe , then spend the required cells.
Mechanics [ ]
The player can only have a amount of Perks at once. Each area cleared in a run allows one more mutation, up to a total of 11 (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 Perks are associated with and scale their benefits with a specific stat. That is, Perks' 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 Perks provides an extra 90 base DPS and the player's Brutality is 2, the final extra DPS is 90 × 1.152-1</su> = 90 × 1.15 = 103.5 ≈ 104). Note that damage and DPS bonuses from mutations are not affected by gear-specific damage bonuses or Affixes .
Colored Perks have fixed benefits unaffected by Stats, except for Instinct of the Master of Arms and Frostbite which scale on the highest stat.
List of mutations [ ]
There are 54 mutations in the game: 12 for Brutality, 12 for Tactics, 12 for Survival and 17 that are Colorless.
