Light Demonslayer Arm (3.5e Equipment)
From D&D Wiki
Description: The Light Demonslayer Arm occupies the same space on the body as a glove. While wearing this, if you aren't a demon, or have the demonblood subtype, your total level decreases by one, and you gain no benefit from Demonslayer Claws.
Activation: Activating the Light Demonslayer Arm is a swift action. Because of its weight you can't use your second hand. The Light Demonslayer Arm is considered a two handed weapon. Deactivating it is a free action.
Effect: When the wearer makes an attack with the Light Demonslayer Arm, it deals 2d6 bonus damage against demons or those with the demonblood subtype.This is treated as a natural weapon.
Effect 2:If you are tripped during your own trip attempt, you can deactivate the light demonslayer arm to avoid being tripped.
