Endurack is quiting!

20 warmth, 20 enchant, 20 fire mastery, 1 mana shield, 1 teleport, 1 shiver armor, 1 frozen armor, 1 firebolt, 1 fireball, 1 charged bolt, 1 telekenesis, 1 lightning, 1 chain lightning, 1 ice bolt, 1 ice blast.

You'll finish that at 61, then you can just keep putting points into mana shield or shiver armor.

Perfect gear would be 6 socket phase blade with fire jewels, 4 sock armor with fire jewels, 4 sock shield with fire jewels, 3 sock helm with fire jewels, any gloves with 20%ias (preferably some AR, dex, energy, mana, vitality and/or life as well), silkweave (for mana), arachnid mesh, 2xsoj, and mara's.

You'll want to put a lot of points into energy, as your mana shield will be taking most of your damage eventually. Don't skimp on vitality, though. You'll need enough str to wear your gear, and enough dex to hit your opponent.

Charms are +fire skill charms with mana or life.

Strategy: cast enchant, teleport to target, hit target, don't get hit.
