It doesn't have more mana than Heart of the Oak. Also, the extra resist and fast cast rate is nice, but what do you need resist for if you're doing jack shit for damage? +3 Skills is going to add a lot to skills if they're maxed (expecially now with synergies).

Speaking of which, does anybody have a program that shows damages with synergies for any classes? (I'm curious about the damages around the lvl 30 range.)

What is it they say about silence being golden?
