Build:Sandwich Worldshaper

Description
The idea of this build is to trap the heroes in a sandwich of Grael Bedrock walls in a narrow hallway. Cerberus Inferno is the meat in the sandwich, ticking persistent damage to quickly wear down the trapped heroes. The remaining ability can be altered to suit your preference; anything that works on top of breaches can be used.

Tips
While theoretically possible to pull this combination off with any veil demon, and certainly it is much more deadly in the hands of a Chaos Weaver, the Worldshaper's Winds of Auros makes it much easier to pull off in practice. Place your breach and your wall down in front of the heroes, then quickly fling them against the wall with your Winds and place the other wall behind them. Try to leave as little room as possible in the sandwich so there are no corners to hide in to avoid the inferno's damage. Summon an elite in the trap when you successfully catch a majority of the heroes to ensure their death if they fail to quickly take down your walls.

Variations

 * Aside from the 33% cooldown reduction, the rest of the talents are optional.
 * Consider swapping Fungal Spore out for Paralyzing Field for a more control-focused option. The consistent stuns in the tight space between the Grael Bedrocks will help control the heroes and prolong the lifespan of your walls.
 * You may prefer Grael Vitalis or Veil Fade when not using Fungal Spores in the trap.
 * Veil Shroud might also be an interesting choice if the majority of the heroes are ranged. With the right placement, you may be able to make it very difficult for the heroes to destroy the walls.
