Dark Bead

A glimmering orb of pearlescent black energy streaks from your palm towards a creature you can see within range. Make a ranged spell attack against the target. On a hit the target takes 1d10 necrotic damage. If used on a corpse it rots away the flesh leaving only bones behind; it takes 1 bead to rot a tiny or small creature, 2 for a medium creature, 3 for a large creature, 7 for a huge creature, and 15+ for a gargantuan creature.

This spell’s damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
