Void Strike

With a short phrase of void speech, you gather writhing darkness around your hand. When you cast the spell, and as an action on subsequent turns, you can unleash a bolt of darkness at a target within range. Make a ranged spell attack. If your target is in dim light or darkness, you have advantage on the roll. On a hit, the target takes 5d8 necrotic damage and is frightened of you until the start of your next turn.

At Higher Levels. When you cast the spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
