Demon Slayer is an Invention perk that increases damage dealt to demons by 7%. It can be created in weapon and armour gizmos.

Demon Slayer applies against the same demons as darklight. The perk has an effect on K'ril Tsutsaroth in normal mode. However, it does not work against K'ril Tsutsaroth in hard mode, or against the Twin Furies.

The Demon Slayer perk is an excellent option when augmenting equipment for Slayer training.

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