Stealth

Stealth is an status effect in Darkest Dungeon that prevents monsters or Grave Robber from being targeted. Generally, it will only last for the first two rounds, though there may be some exceptions. Enemies that have Stealth can still be hit by attacks that hit multiple targets. Additionally, some hero skills can bypass Stealth and can target enemies with it. If an enemy is hit with such a skill, they will no longer have Stealth.

It is signalled by a purple eye icon and monsters are a murky grey-blue while they have Stealth.
