[@vancexentan] nay friend. It would have specific health conditions that need to be met, with only a single target recipient of the spell. Likely the char would need to be fatally injured or below a 5% max hp threshold. Prevents further damage dealt/receiced and prevent any actions until healed up to a certain %, lets say 25%? 
Otherwise I could just do a stasis/desoerate prayer combo and have them leap back into the fight.
