Burn everything with disintegrate, put tornadoes on them, then teleport to safety, watch the enemies hit your illusion while they are burned by firestorm.
Use ice crystal to extend your range if the situation requires more distance to survive. Or just to hit more enemies and slow them.
Really high dmg build, excellent for bosses, especially if you have to monkey around to survive, as tornadoes are kinda fire and forget. But don't forget to st the enemy on fire first.
The build can be improved with gems and other shenanigans but this is intentionally a budget build that works perfectly. I enjoy it anyway.
