While updating the Monster Boss Modifiers article in the wiki this morning, chiefly with the new info from the BradyGuide preview (the page is still a WiP), I was reviewing the screenshots and Beta videos of various bosses and enjoying the show. All of them were seen in our forums during the beta, but I’m pretty sure I never posted any videos of Wallers or Jailers on the main page. This means that those of you who weren’t in the beta, or never got “Beyond the Cemetery Gate,” or didn’t endlessly run the Den of the Fallen, the second level of which was the only place to find such monsters during the last couple of months of the beta — probably never saw them.

To remedy that shotcoming, here are a couple of very cool videos showing off how Wallers play. It’s one of the more interesting properties, since it varies between Champions and Bosses. Champs can only create short and straight walls (at least on Normal), while Bosses can corral you in three-sided rectangles that force you to run back to them if you wish to escape. Imagine that with Vortex, Nightmarish, and Frozen on Inferno? Your only real choice would be to restart at the last checkpoint, or leave the game entirely.

Besides locking you in, Walls will also block projectiles, and ranged attackers who aren’t blocked in can be frustrated by their inability to shoot the Boss or Champion that’s casting the walls in the first place. One of them drove my Demon Hunter crazy in the Fields of Misery during the beta, and they’ll no doubt repeat that trick many times in the final game.

Here’s the video of a Boss with Waller, building house foundations to lock players in. (The titles on the videos themselves are reversed.)
