I'ts always helpful to have either Quelkulan/Cyril as Defense Eido and an Eido (please Rav Mains correct me)
a +45% Flame +25% attackspd eido +25% attackspd with +24% DMG as DPS eido.
*runs back to forums I've actually knowledge from*
for 90 pvp, unless u want make full tank with Ashe bottoms, just don't use cdmg-150. Really useless. It's not too hard to have 600+ cdmg for full geard.
