Arms of Hadar

Invoking Hadar, you cause tendrils to erupt from yourself. Each creature in a 10-foot Emanation [Area Of Effect] originating from you makes a Strength saving throw. On a failed save, a target takes 🎲2d6 💀 Necrotic damage and can't take Reactions until the start of its next turn. On a successful save, a target takes half as much damage only.

The damage increases by 🎲2d6 for each spell slot level above 1.
