It has absolutely annihilated the entire groups of enemies for me. One spell won several encounters. When you’re shooting them with range, they have no choice but to try to escape, and they’ll often walk through the entire thing and kill themselves. It’s pretty crazy. I doubt it would work that well in a table top game since the DM would likely jump out of it, or figure something else out, but the game logic engine will just walk them right through it and kill them all.
