Hey, I've created a spell that I would greatly appreciate some feedback on, before I submit it to my DM
The aim of this spell is to provide a means where by a cleric can heal a fellow PC without having to expend any of their spell slots (ie it is a cantrip) and without having to use his/her precious action for the round. The obvious issue with having at will healing is that a cleric could use it out of combat to fully heal the whole party!
However, if the spell is a reaction triggered when an ally is damaged, then that would both prevent it from being used out of combat and save the cleric from using his/her action. That still seems very powerful - although the cleric only gets one reaction per round, there is little reason not to use it every round. So, taking a leaf out of the haste spell, I suggest the ally should give an action, bonus action or reaction up too. Which of those do you think would be appropriate, and is there anything else that should be done to balance the spell?
Invigorate
Evocation cantrip
Casting time: 1 reaction, which you take in response to seeing an ally within 60 feet being damaged
Range: 60 feet
Components: V
Duration: instantaneous
The creature that was damaged regains hit points equal to your proficiency bonus. This spell has no effect on undead or constructs. When the spell ends, the target cannot take actions? bonus actions? reactions? until after its next turn, as a wave of lethargy sweeps over it.
