I need help on increasing the dot damage on my totems, I can clear up to t11s fine but it seems that t12 and up are giving me grief as I guess my totems don't do as much damage as I thought.
Can anyone help me figure out how to increase my dps?

my unbuffed damage:


buffed damage:


edit-My bad didnt know my characters where hidden.

Can't see your gear (you set your profile as private) so I can't advise you there. But have you tried Elemental Equilibrium? Ball lightning is safe and easy way to trigger it. Also I would recommend using Righteous fire on totems for map clear and Scorching ray for boss and tough rare kill.

SR doesn't hit so fire penetration from Heart of flame is useless. Better to use Breath of flames as RF and SR counts as burning damage.

I feel like you focus on mana nodes a bit too much. Those points would be better spent in life nodes.
