In terms of "what to gear"... Ive read defense is best, then attack, then skill, but how much better is defense in terms of sacraficing attack?
My question pertains to a Silver Gladius im using (110a+22s - blind), with a great targe(52d+15s)...and i just got a crystal gauntlet(75a+30d-15s - none)
When i started writing this i thought id be replacing the gladius, but i just realized one if left-handed, the other is right... so i guess im asking now, would you replace the Great Targe w/ the Crystal Gauntlet for the 75 attack over the 22 defense & 30 skill lost?
