@megamaster22, if you mean cosmic monolith, you must equip all your items with dark ressistance, (especially lvl5 weapons with 50% dark ressist). At least 50% dark ressist per character, but more is much better.
I love this game. It's just the difficulty I am looking for. I've finished it with all 3 characters, and I recommened the engineer, as he was the most fun. The psionic was the least fun.
Some levels I won with less clicks than the PAR. Level 28 with 6 clicks instead of 7, level 31 with 9 clicks instead of 10, and level 44 with 29 clicks instead of 31...
I have wondered that as well.
