Thank you for the tips, I just tried it out and it works excellently! Just one question, how do you make the black-manastones absorb mana stones (to increase capacity) but not absorb the other black-manastones?)
Also, I'm finding berserker ring (+1 energy if no shields/armor) to be mildly useful (it's better than windmill, which is a relic!), although this build uses more mana than it needs energy/stamina.
