Shockstick (3.5e Equipment)
From D&D Wiki
This magical weapon discharges an electric shock on a successful melee touch attack, dealing 2d6 electricity damage. A shockstick also has a stun setting, which deals 2d6 nonlethal damage instead. A creature using a shockstick in either of its settings gets +3 to an attack roll against an opponent wearing a lot of metal. For the case of weapon proficiency, the shockstick is considered a simple weapon.
