I guess for Pupp Theatre you could try to rush with different classes, amuse yourself by trying to get record number of people in the dungeon by “overcall” and see how mad people get, try to kill the main puppet without triggering any plot twists, do full clears & practice spellbomb with wizard or sorc/deva, archer/quiv accuracy. Eh that’s all I’ve got! I like the dungeon so it doesn’t take much to keep me happy in there.
Someone did try to convince me assassin can get the most out of it, but I have to admit I’ve not gone and looked properly because I don’t really like the look of it over csilk. Maybe one day.
