Vicious Encouragement

You unleash a string of insults laced with subtle enchantments at one creature you can see or hear within range. The target heals 1d6 Hit points. 

Cantrip Upgrade. The Healing increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), and 17 (4d6).

Cantrip Improvise version: When voice acting/roleplaying what your character said to the target, with a submissive voice and act, the target will be gain double healing from the spell.
