Lupinaxe

The Lupinaxe is an axe whose head looks like a wolf. It can summon a dire wolf. On contact with a foe, the axe emits a howling noise like a wolf. If thrown, after contact, the axe will teleport back to the hand of its wielder.

The axe was used notably by Arun Maerdrym in 464 DR in the Sword of Anauroch to strike the Duskstaff of Sarael, an act that would kill him and his son Khelben "Blackstaff" Arunsun and eliminate their phaerimm enemies in the process, leaving a crater of glass behind.
