Toll the Dead

Action | 60 ft | V/S | Instantaneous

You point at one creature you can see within range,
and the single chime of a dolorous bell is audible within
10 feet of the target. The target must succeed on a Wisdom
saving throw or take 1d8 Necrotic damage.
If the target is missing any of its Hit Points
it instead takes 1d12 Necrotic damage.

Cantrip Upgrade. The damage increases by one die when
you reach levels 5 (2d8 or 2d12), 11 (3d8 or 3d12),
and 17 (4d8 or 4d12).
