Ok, I want to play a secretly good guy in an evil party. My goal is to help NPCs not to die to my mates without them noticing. So, resurrecting, reviving, revivify, healing (that part is easy as long as the NPC is just left "dying") would all be options.
But cleric 13 casting resurrections would not be an option, because it costs 10k gp, a high level spell and needs much too many levels in a class I don't want to take.
What ideas do you have? Any solution that does not involve spending tons of levels in a full caster class or tons of gold in every NPC I save?
