It's unlikely to be the same guy really, but if the DM I knew was related to him, I wouldn't be surprised. Here's something else he pulled.
3.0 game, our first, in fact. The DM simply thought he could continue to use his 2e game with no changes, and was constantly flummoxed by the new rules and lamenting how "stupidly powerful" we all were. We were fighting a vampire in a cavern, when the Fighter finally had enough. He dropped his shield, downed a potion of Bull's Strength, and put a two-handed grip on his Dwarven Waraxe and went to town on the guy, boosting his damage per hit by 4 points- which you wouldn't think was too bad, but the DM freaked out when his precious NPC's hit points melted away.
"The last attack hits the vampire with such force that it cleaves through him and into the rock pillar he was standing next to, cleaving it in twain. Suddenly, cracks appear in the cavern's ceiling and it collapses!".
This, IMO, is the critical difference between a "killer DM" and a DM where sometimes the PCs die. It's clear retaliation, and there's no place for it.
Yeah, I've seen something similar. I managed to last 2 sessions in such a campaign, because I was overly forgiving of such behavior back then.Yeah, literally rocks fall, though only the Fighter died. But wait, there's more! Upon recovering the body, an NPC Druid wandered by and offered to restore the Fighter to life. The DM rolled some dice behind his screen and our Fighter came back as a Gnome. -1 level, -2 Strength, and unable to use his old armor or shield (but by 3.0 rules, he could at least use his Waraxe as a two handed weapon) as his "reward" for defeating a major foe.
And of course, no vampire xp since he "died in the encounter"!
