Longicolnis 

The Longicolnis is the sacred spear forged from Shaher's missing horn in Tactics Ogre: The Knight of Lodis. It is the only weapon capable of piercing the Sacred Demon's skin. It is sought after by every party in the game for it's ultimate power.

Guy 1: I can't break through Shaher's shield!
Guy 2: Have you used the Longicolnis?
Guy 1: *facepalm* That makes sense.
