The following may be out of date.
A general shell for any race or element of Archmage should be similar to the above build, but without the expenditure in Fire or Wildfire, reprinted here as follows:
Disruption Shield, while tedious, provides an incredible amount of shielding with correct use and allows Archmage to survive sudden unexpected damage without your other shields up.
Stone Wall allows you to isolate yourself, a problem enemy, or to block off sight or passages.
Disperse Magic allows you to get rid of powerful and annoying sustains on opponents; Quicken Spells lowers the CD on your important utility spells; Metaflow allows you to just reset their cooldowns, all very strong.
The category that should probably be your first unlock. Time Shield is an instant, high strength, long duration shield; Time Prison allows you to wait out unexpected explosions from your Disruption Shield and save escorts; Essence of Time is global speed, though it's best saved for near the end of the game when the very high sustain is more manageable.
Technique / Combat Training: 0/1/0/0
Level 4 is both when Phase Door and Teleport allow you to choose where you want to land
Arcane eye and Vision allow you to know what's coming and Keen senses allows you to see invisible and stealthed enemies and gives you more crit chance.
Is your bread and butter way to survive - Arcane Reconstruction + Arcane Shield gives you large shields, Shielding makes your shields stronger, and aegis buffs already strong shields into unbreakable ones.
