A spear trap is a trap that fires spears when stepped upon by a player or monster. They hold 2-7 spears and deal 1d26 damage to you or 1d10 damage to monsters. The game will prompt you if you try to walk over one on less than 40 HP.
Much like other traps, spear traps cannot be disarmed, but they do have a limited supply of ammunition. They are fairly uncommon, appearing only in the Ossuary branch, in the Tomb and on Zot:5, in the chambers approaching the Orb of Zot.
