Information:
These are only found scattered around T2A in the desert Northwest of Papua and across the "bay" from the desert on Titan Beach. They are also found in level 3 of Wrong (so I am told).
The basic description would be: an earth elemental with high level magic. They hit hard and cast a shit load of magic. They are not impossible but handle with EXTREME care. They can cast combos and have been known to teleport on you since the UO:R patch. Prior to the patch, I was once hit with an Explosion/Paralyze/Energy bolt combo and died. Who knows what nastiness they might have been coded with since then.

How to kill:
Mage: Fight at a distance (they will pathfind to you wherever you are or just teleport onto you), but do not mana dump them. Keep yourself alive by healing and cast an occassional flamestrike and ebolt combo and meditate as you can. They will try to machine gun you with magic arrows. Once they start casting magic arrows at a slower rate (and continually) start your magery kill combo or cast Energy Vortex/Blade Spirit and finish them off. If a Tamer, just sick Godzilla on them. If you have a mage buddy, one mana drain it while the other does the healing thing. Drop Energy Vortex/blade spirit to finish.
Archers: Keep your bandages going and shoot it to death. Forget about casting poison as they have 100000000 magic resistance, and even if you do sucessfully cast poison on him they will just cure themselves.
Warrior: Best if done with friends that can heal and cure you. Keep potions handy and keep the bandages going. It will eventually die to your onslaught. Watch your stamina as their hits and explosions will likely make it drop.

Loot:
400+ gold, cooked food (no bullshit), higher chance of magic items than cyclops, gems, and a chance of getting a level 5 treasure map.
