Bear Traps

Bear Traps are very dangerous traps, usually set to keep out unwanted visitors, when not used for hunting animals. It's essentially a spring-loaded trap sitting on the ground, waiting for someone to step onto it. Once that happens, the two halfes of the iron close apruptly, and the force and sharp edges on the rim cause serious injury to the leg.

Note that in Britannia there are bear traps in circulation that automatically reset themselves after striking. Touching the trap is impossible for anyone but the one who set the trap, as the danger of injury is tto big. However, the Vanish spell can remove this danger. Thankfully these traps vanished after the time of the False Prophet (only to be replaced by caltrops).
