The following build is one of the primary builds that I've been using for about a month or so. It has served me well in elite areas such as DoA, Slavers' Exile, and other dungeons. Actually, I did a normal DoA run a couple weeks ago and this build wiped out two huge groups of Margonites in about 7 seconds.
The equipment that I use is as follows:
Adept Tormented Fire Staff of Enchanting
Radient Insignias
Survivor Insignias
Rune of Superior Vigor
Rune of Minor Energy Storage
14pts in Fire Magic
13pts in Energy Storage
You might be able to put in a Rune of Attunement or two if you desire more energy but with 13pts in Energy Storage, I have 85 energy and that's more then enough.
1) Searing Heat
2) Teinai's Heat
3) Meteor Shower
4) Savannah Heat
5) Arcane Echo
6) Mindbender
7) Mark of Rodgot (Or a Resurrection Signet / Deep Freeze)
8) Fire Attunement
Using Arcane echo, you have the choice of echoing Meteor Shower or Savannah Heat. This gives you more AoE damage or twice the knock downs, which is useful in the DoA.
Mindbender, combined with an Adept Staff, gives you 60% faster casting of Metor Shower. Fire Attunement helps manage your energy. I usually have around 40 energy left over after casting all attack spells and by the time your bar is recharged, your energy will be full again.
