World of Horror/Perks

Upon levelling up, you can also select one of three random perks; you can reroll which perks are offered to you at the cost of +4% Doom. While some are able to be taken no matter who you play as, most of the perks in the game are unique to your selected character.

General
These perks are able to be taken regardless of your current character.

Exclusive
These perks are unique to the character you've chosen for your current run.

Toshiaki Wakamatsu
(Note: With the exception of Aura of Azal-Hoth, which Toshiaki starts a run with, these effects are not applied upon gaining the perk, but are instead actively used as spells are.)
