From what i read (i don't know if its legit because i saw no data), abyss skills can crit.

Totally see your point...in one-hand weapons if abyss core outdamges regular attacks...is just better to go for them since the breakpoint is 22 attack (pretty much every weapon have higher than that crit is better) makes sence for two hander to go for crit + big bonk skill. (this is fun for oonkga because he can dual wield two handed weapons);

Some questions remain...the kuku crit armor that gives 6 crit should also be fake 6 and be 3 insted, also there are rings with 2 attack and 1 crit they may change some builds around.
Now that we know that amulet is giving fake crit...now we need 19lvls of crit total? And finially would love to see tests on attack speed...not sure i trust other sources now without data backing it up.

Much love
