3 things I need to know about Arans

Except in case of crit weapon + SE, where the Aran already has 70+15+10% crit, so the 5%/20% ring is better.

Gotta say though, I've killed a fair number of Nibelungs now and haven't seen any Neo weapons yet :/

Crit weapons suck, and it still wouldn't be better until your combo is 100+.
