Today we had an encounter with a npc that first seemed like a barbarian with a really low int level. But when we dwell on it i saw him casting eldritch blast on something. So he has a lvl in warlock. We had some tips that the god in our setting liked him so maybe he somehow is a cleric as well. At the end od the session we have been informed that our npc is only 3 level. He was way too epic and rich for a 3 lvl. Im not really into dnd so do you guys have any idea how that happened?
