Vitalize

A creature you touch regains a number of hit points equal to 1d4 + your spell casting modifier. This spell has no effect on undead or constructs.

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

Special. Any creature may only benefit from the effects of this spell a number of times per long rest equal to your proficiency modifier after which a creature can still be stabilized when dying by the effects of the spell but will gain no hit points.
