Invoke Hive Magic

Invoke Hive Magic is an ability used in the Haunted Altars of Sorrow activity. Greedy Ghouls drop 30 treats each when slain, and once 80 treats are banked, a Shrieker appears over the enemy altar with a Devoured Ogre inside an Immunity Shield. A pile of hive debris also appears over a magic circle.

Guardians use Invoke Hive Magic over the circle to turn the Shrieker to their side. The Shrieker then fires on the Devoured Ogre and removes its shield, allowing the Guardians to defeat it.
