The Destroyer of Destiny requires that you destroy all 4 Activated Pillars in the Royal Crypt at once. This can obviously only be done when going to face the Skeleton King.
The pillars are placed a fairly good distance apart and all of the AOE or AOE-like attacks that I have tried with either the Monk or Demon Hunter have failed to destroy all 4 pillars. Replaying the section from when the Templar joins up to the pillars is getting tedious and I'm really at a loss.
What character/attack/strategy should I use? Is this something where you need a 4-player co-op to achieve it or something (exact timing on this would be bananas)?
