Spirit Wrack

6th-level abjuration

Casting Time: 1 action
Range: Self
Components: V, S, M (powdered silver worth at least 50 gp)
Duration: Concentration, up to 1 hour

You create a shroud around you that causes each spirit within 30 feet of you immense discomfort and makes it hostile toward you. Each such creature you choose that starts its turn within the shroud must make a Charisma saving throw. On a failed save, the creature is wracked by immense pain and is unable to take reactions, can’t concentrate to maintain a spell or power, and has disadvantage on attack rolls and ability checks until the start of its next turn.
