I thought I'd share my build, the one that didn't work as well as I'd hoped. I think it's more an isssue of me playing it poorly than it being a poor build, but take it for what it is, maybe you can do something with it.
Equip = Minor Earth, Earth Head gear (all I have that's usefull)
Armor of Earth
Arora of Restoration
Aurora of Restoration
Armor of Earth
Spam Stone Daggers. Between Ether Renewal and Aurora of Restoration, you'll heal yourself for about 800 over the course of 10 seconds. Your energy will be full by the time your done.
Then spam Stone Daggers for 5 more seconds. Net heal about 200. Use about 30 Energy.
Hit your 2nd Ether Renewal (arcane echo'd version). Spam Stone daggers. Again, net heal about 800. Follow with 5 more seconds of Stone daggers. Net heal 200, and you should be at about 3/4 Energy.
Rinse. Repeat. Never run out of HP or Energy.
I found the casting of Arcane Echo to repeat Ether Renewal to be too mana consuming and too complicated for me to pull off effectively. It worked fantastic the first round, but between dropping buffs and timing issues, I couldn't never get it to work well a 2nd time per fight. Backfire was too easily removed by those with Hex Removers, because I didn't have another hex I could lay on top of it. My Buffs dropped too often, and would need critical mana to put back on.
There. I hope that leads some of you to start thinking in a new direction besides all the huge flashy damage. People say Stone Daggers suck, but when you cast it non-stop for a few minutes, it really adds up.
