I just modified the "Ohren" Fight Class.
I added Ice Nova, Ice Block, and Summon Water Elemental, Comet Storm, Ice Barrier
Ice Block below 35%
Cold Snap below 65%
You should use Glyph of Regenerative Ice
Okay, i found the cave finally, but there is an "elite" in there, he kills me easily, and when I run back from gy it get stuck in the mountain above the cave.
I die in like every 5min, becuase it does not step out of "Fiery Ground", it hits like 4-5k, and i have 40-50k hp at lvl 90
