In the Ritual league, you have to fight waves of enemies you previously killed around a special altar to receive tribute. Seems straightforward enough, but the amount of tribute I get from each encounter seems almost random. What affects this amount and can I influence it?
I know that the waves are formed from enemies killed around the altar before its activation. What I don't quite understand is whether it's all monsters killed at any point or just some. Is there a limit? Should I try to draw more enemies into the ritual area before knocking on the altar?
