Each Killer and Survivor in Dead by Daylight have 3 unique perks. This character will start with the tier 1 version of their unique perks unlocked. At first, these perks are exclusive to the character they belong to. The can be taught to other Killers or Survivors by unlocking their teachable variants.
A character's unique perks can be taught to other characters starting at level 30.
At levels 30, 35, and 40, an orange teachable version of one of the character's unique perks will appear in your Bloodweb. After unlocking one of these teachable perks, the perk will begin to show up in other characters' Bloodwebs like a regular perk.
Alternatively, teachable perks can be purchased from the Shrine of Secrets. Each week, a selection of four perks will be available for purchase with Iridescent Shards. You do not need to own a character to purchase their perk from the Shrine of Secrets. After the perk is purchased, it will begin appearing in other characters' Bloodwebs like other perks.
