Touch of Healing

A creature you touch regains a number of hit points equal to 1d4, up to the creature's half of maximum health. This spell has no effect on undead or constructs. If used on a target which is at 0 hp, the creature becomes stable instead of healing.

This spell's healing increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
