Accursed Specter

The Accursed Specter can move through other creatures and objects as if they were Difficult Terrain. It takes 5 (1d10) Force damage if it ends its turn inside an object.

Melee Spell Attack Roll: your spell attack modifier to hit, reach 5 ft., one target. Hit: 1d10 plus your Charisma modifier Necrotic damage, and the target can't regain Hit Points until the end of the Accursed Specter's next turn.
