This pocked and notched piece of yellowed bone seems to have once been used as the pommel for a dagger, though the blade is now missing.

When you grasp the hilt of a spectral dagger, a “blade” of ghostly light coalesces into existence. The weapon has no enhancement bonus (and can’t be imbued with one). Attacks with a spectral dagger are treated as touch attacks, but the weapon does not deal damage normally. Instead, any target struck by the weapon is affected by a chill touch spell (Fort DC 11 partial or Will DC 11 negates; see PH 209). A spectral dagger fades away if it leaves your hand, so the weapon can’t be used to make ranged attacks.

Prerequisites: Craft Magic Arms and Armor, chill touch.
