Burnt Boots of the Trapfinder - Weird Magic Item #9

Inspired by the incredibly excellent Weird Magic Item generator over at Donjon.bin.sh, I've been coming up with a few of my own system agnostic weird magic items to put in the many games I run, be they 13th Age or Beyond the Wall...

Eventually I want to try and put them into a randomizer, but I need to generate a few first. I'm going to try and post one every other Wednesday. Please let me know if you end up using an item I've created in your own game. You can find the entire series here...

Burnt Boots of the Trapfinder

Haunted by the unusually greedy ghost of a particularly unlucky thief, these shiny black leather boots smell slightly of burnt leather and flesh, and cannot be worn. Instead, they can be set on the ground in a room, corridor or other discrete area and activated by paying the ghost's price. Once the price is paid, the boots traverse the corridor or room and trigger any traps that would be set off by a person walking, standing or entering a trigger area. The price begins at 10gp and doubles each subsequent time the party calls upon the boots. The price must be put into the empty boots and disappears to the ghost's ethereal hoard, but it can be paid in any form, be it coin, raw gems or items worth at least the price (though the boots never make change, even when grossly overpaid). The boots can never be destroyed, except by a sphere of annihilation or other potent disintegration, but they do show appropriate damage. For instance, if the boots are used to trigger a spray of acid, they would be visibly singed by the caustic spray. Any damage slowly disappears over a 24 hour period until the boots are once again a pair of shiny black leather boots. It is rumored that the same unlucky thief once had a pair of gloves, but no one has seen them (or at least admitted so).
