Personally, I think Aldur's is perfect for a meleementalist
20 Oak Sage
1 Moulten Boulder
1 prereqs for a total of 106 skill points
Fissure should be fully synergized and the fire side of Volcano should be fully synergized as well. For bosses, just stick a volcano under them. For crowds... lay down a fissure, Throw a twister charge in behind it with Geddon running and start swinging. I'd experiment with Amns and Shaels in the jagged star.
The object here is maxing Armageddon damage and using Hunger on a wearbear to keep you alive. If I did my math right with the set damage bonus you get 106 health per bite on a 6 frame attack (assuming 3 shaels in the jagged star) with the Wearbear while your Armageddon does 4648-5491 damage. Armageddon will only last 12 seconds with this build though so you'll have to recast it periodically.
