magma dungeon is much better for a WS.. i dunno why would you want to waste time killing kasas in thor
with penomena & 2 SR you would get nice exp in juperos
Juperos is good exp, but zomg can it be rape in there if you don't prep with enough meat and have high reductions. You can do well in thor though, effectively mobbing kasa, but for kasa it's a toss up between gtb or penomena, you either get raped by fire balls or spiral peirce your choice. I generally did better with a gtb on, but I would never try to kill kasa w/o a WS, you need a bunch of buffs including maximum overthrust and ice endow to do well there.
