I present the Factotum with a DMZ and a mindless enemy immune to Sneak Attack. The area has no cover and the ground is covered in Fine objects that cause a great deal of noise when stood on, making sneaking impossible. Also Tremorsense.

I present to your Rogue, an Undead Dragon. To your Polymorph Rogue, I present an Undead Dragon in a DMZ.

I present to your Wizard, the world explodes. While in a DMZ.
Or a DMZ while surrounded by an army of Chicken Infested Commoners with those Caster eating chickens.

I present to your army of every single Class ever... Rocks fall everyone dies.
