So there I was, facing off against Baizel. I was standing in a doorway, so I could shoot her and her entourage, but still back up and make a one-monster bottleneck if needed. I was launching Fireballs at her, trying to pick off the nearby skeletons, and she was advancing toward me. Suddenly, my character screamed, and I got the "You have died" screen. Right before the screen came up, I figured out my error:
The "doorway" I was standing in was an open portcullis. As Baizel got closer, the blast radius from my Fireball tripped the lever controlling said portcullis, and it came down and crushed me.
Anyone else gotten yourself killed in a spectacularly stupid way? Want to share how it happened?
