i need to no whats th average damage/crits of a destruction lock at lvl 60-65

My Shadowbolts could crit for about 1k-1.5k at 64.

Well, that was a long time ago, so it's just a rough estimate.

bananaz is right.shadowbolt is the best to crit and u get a bonus sometimes i forgotten its name but its incrasin shadow spells so its easyer to get crit with shadowbolt
