Spikes are the most common trap in the dungeons. They appear both as a floor hazard and on walls, and are the only trap that generates on walls as well as on the ground.
Spikes are also one of the three kinds of pit, alongside water and Toxic Ooze.
Resisting them
The Spike Ring carries a Spikes Resist effect that negates all damage from spike traps.
