Hello there, I think to maximize the exp/hr ratio you should get all floors, except for the top one, because the asuras wont come all together because of the four towers there, and then go straight to bottom floor then make your way up again, still thinking of exp I would skip too destroyers and the others creatures that belong to the access quest to the mirror, and yes, for a 250 ek, one true asura can be the reason you end in temple, considering that you will have more asuras with it in the box
