@Overlord_Mateus pretty sure that it says in one of the earlier chapters that experience is capped per event which would probably apply to merit also. 10 to 20 demons but they need to be killed individually, corpse explosion kills them simultaneously. So you can only gain one star at a time. So if corpse explosion gives 10 billion experience you still only get credit for 10 million experience or so. (I might be remembering this from the novel tho and I don't remember reading about merit cap
