Arms of Hadar

Level 1 Conjuration. Warlock.

Casting time: Action

Range: Self

Components: V, S

Duration: Instantaneous

Each creature in a 10-foot Emanation from you makes a Strength saving throw. On failure, it takes 2d6 Necrotic damage and cannot take Reactions until the start of its next turn. A successful save halves the damage and prevents the reaction restriction.

Higher-level slot: Add 1d6 damage per slot level above 1.
