Basically use your 4, dash with his 1 enough to fill up his battery and charge his redline, cast his 2 to have damage reduction, and with the [Archon Vitality] you can manage basically murder everything with his 3 once you are fully charged, press once to freeze everyone and then hold it to strip the enemy armor and burn them to death, if you need energy you can also just freeze the enemies to make them drop the energy orbs with the [Archon Flow].

Have Fun!
