How do you guys decide on triggering the boss? I have yet to kill even the first one. Do you just sit on a bunch of Oblivions to blow up his palace beforehand, or aim for a specific build (the Warrior is really good at clearing the map with heavy counter + vampirism, but that sucks against the Lich), or do I just suck at this so far?
Typically I’ve been going to loop like 8-9 and going for it. Maybe that’s the wrong approach.
