Don't bother using Archon Teleport either, as Belphegor can not path properly (according to old posts in thread, not sure if it's fixed.)
Use Archon Pure Power to lower cool down to 100 sec, then passive Evocation to lower another 15%, so down to 85 seconds. Make sure your dps is up high enough that you 1 hit trash mobs. Critical Mass is a good passive to use but you don't crit in Archon mode, so if you can keep it up swap it out for Blur or Glass Cannon. If you can't keep it up, use Critical Mass.
I don't bot wizards but these are my suggestions.
edit; make sure you enable combat looting too. You don't want to run back and forth after mobs are dead wasting seconds.
