My fav thing recently has been giving everyone the jump buff and just bouncing around the map. Main char is a barb1-monk3 right now. Potion of speed and the monk dash ability means he can literally just circle the map with jumps. Just found a weapon that does damage when he lands too, although I haven't used it yet I feel like it's going to be almost cheesy levels of ridiculous.
Also a fan of throwing or pushing enemies into the circle of blades. With karlach and my barb-monk there's plenty of enemies flying around. Or void bulb..
It would be nice to just be able to cast the rituals from the spell list rather than 'prepare' them for 2 seconds each time
