Shackles of the Grave is a 19th level cleric Daily power that was introduced in Heroes of Shadow.
A blast of black energy washes over nearby creatures, marking their souls as your divine property.
Close blast 5
Target: Each creature in the blast
Attack: Wisdom vs. Fortitude
Hit: 5d6 + Wisdom modifier necrotic damage.
Miss: half damage.
Effect: The blast creates a zone that lasts until the end of the encounter. The first time any enemy dies in the zone before the end of the encounter, it rises at the start of its next turn as an undead creature allied with you and your allies. Until it dies again, the creature is dominated by you. It has 1 hit point (the creature takes no damage from an attack that misses), no healing surges, and a -2 penalty to all defenses.
