Horror

Horror was a debuff that was inflicted onto the player by many enemies in Revengeance Mode. It reduced the player's defense by 15 and movement speed and acceleration by 15%. It additionally altered vision similarly to the Darkness debuff.

Equipping a Laudanum or Draedon's Heart would cause the debuff to last twice as long, but instead of giving any negative effects it would grant a 10% bonus to movement speed and acceleration as well as 15 defense and 10% increased damage. This also changed the tooltip to 'The horror fuels your strength'.

Trivia

 * The debuff was a reference to an effect of the same name from the game, Darkest Dungeon.
