It sounds like you were a player on an escort run with low level NPC's XD 
I know that pain, a bad DM can hamper a game so much, in some cases more than a bad player. As a player can simply die, while a GM has to give up their position XD

When I 'cheat' against my players, I use their own characters against them. "Oh, you're a greedy bastard? Here's a chest in an empty room, a light shining down upon it. Go touch it."

I have a couple of cursed items, but most of which beat the guilds rules over the head until death, so I can't post them here... too NSFW XD all I can say is, Mimic Armor, or the Green Pact from The Elder Scrolls went a little too Evil Dead XD

Oh, I love the heartbeat one - that should drive anyone with low will power insane, or have to use multiple saves to keep it in check XD
