As a GM, you need to remember every piece of equipment that the PCs have, and prepare your traps and obstacles so that they can be overcome, but
not too easily. It’s embarrassing to prepare a pit trap that should hold them long enough for the villain to escape, only to forget that they’re
carrying a ladder at the time.
Of course things will probably turn out the other way. Design a fatal trap with the obvious escape route using a piece of equipment they have handy,
and you can virtually guarantee the players will either forget about it or decide not to use it.
