Dark Spikes

You agitate the shadows, forming them into spikes to strike at your foes. This spell may be cast in one of two ways:

• You gesture sharply at a surface within 60 feet, causing roiling spikes of shadow to erupt from it. Each creature in a 10-foot cube originating from that surface must make a Dexterity saving throw. A creature takes 2d8 necrotic damage on a failed save, or half as much damage on a successful one.
• You clench a fist, forming spears or bolts of inky darkness around you before hurling them at a creature within 120 feet. Make a ranged spell attack against the target. On a hit, the target takes 2d8 necrotic damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
