Not sure how this got past beta testing....
1. Put Blackhole and Mirror Images on your skill bar.
2. Use Event Horizon on black hole, use any mirror image rune ( whatever makes them last longer is better! )
3. Use illusionist passive for effectively no cooldown on mirror images!
4. The event horizon rune sucks up ALL ELITE objects which INCLUDES: Walls, Desecrate, Poison orbs, Plague puddles, Frozen orbs, Molten explosions! And more!
This trivializes content pretty much, I just found out about this by messing around on my hardcore wizard.
Hope it helps, Enjoy!
