Blade staff of devastation - 5.41% increase to MELEE DMG (aka mouse over attack) secret of fire does 270dmg
Power blade staff - 5.41% increase to melee dmg AND spell dmg (aka secret of fire does 283 dmg for me)
Power blade staff of devastation - 7.73% increase to melee dmg AND 2.32 increase to spells (sof does 279)

Just thought id let yall know the difference between "melee dmg rating" and "dmg rating"  dmg is universal and affects spells as well

So in other words to maximize the damage the best one is with power+devastation rather then devastation alone? I wonder how much more dmg do we make with "non-melee" dmg, so is it really worth spending coin on focusing power?

@Syb

what style are you? Cant imagine that a los of 7,5% crit for dragon or drunken without high end gear "not worth to have it" is.

2hand damage, specialy crit damage is maybe more but 7,5% crit is huge number for non harmo monks.
