Sinister agents of the Hag, Crones are support units that drive Unclean Giants into battle. From behind these meat shields they target two heroes at once with Curse of Vulnerability, reducing ACC and DODGE, and Embrace the Dark, a similar spell to Cultist's Stressful Incantation. If forced to the front they use Fetid Censer, which inflicts blight on the front two ranks.
Curse of Vulnerability increases enemy's chances of landing one of their lethal attacks on the Heroes, and worse the Crone hits your party twice with it each attack. She should be prioritized first in any battle.
This enemy has no apprentice level.
