This trap was a lot of fun to use. Not immediately deadly but may prove to be so for some in the party if they aren't careful.

A door opens into a round room (appx 30-40' in dia.) The smooth floor slopes slight down to the center which is about 5' below the entrance level. In the middle is a good collection of armor and weapons (the bait), and a couple of which still have a body in them. On appearance it would seem that a tremendous fight took place in the room. Hidden underneath the pile of armor is a huge lodestone. Once someone with any modest amount of iron or steel on them steps inside the room they appear to start sliding down the smooth floor. But in reality they are being pulled down by the lodestone (magnet). Someone not in armor or in leather may be able to resist it, but studded leather or mail or plate won't be able to. Even just carrying a dagger or sword in hand will pull the wielder down unless they realize what's going on and let go. I ruled that mithral was magical and not iron based so magic armor weapons didn't get sucked down. The victim is now pinned on top of the pile in the center (perhaps a reflex save to avoid any weapons sticking up might be appropriate). The victim also now has to make a choice, remove (and leave) their armor and non-magical weapons or lay there and die. Great way to take some of the fight out of the warriors and get their attention.
