The Demon Slayer ability codex is an ability codex that unlocks the Demon Slayer ability when consumed. The ability increases the damage done to demons by 15% for 10 seconds.

This codex and ability replaced the demon slayer sigil, which was removed on 19 August 2019. The codex costs twice as much to create, but the ability has no upkeep.

The damage increase from the Demon Slayer ability affects damage over time abilities that have a bleed effect i.e. Dismember, Combust, etc.
