Dragon Lance

It's actually more of a sword most of the time. The dragon lance is a legendary weapon created by the combined art of the greatest zarth and fay craft. The blade resembles twin pronged bastard sword made from adamantium but the handle is made from a potent stock of livewood. The blade can shear through the eldest dragon hide. The handle can extend to an incredible length to become a spear, whip, or for the act of dragon slaying itself swell into solid trunk and root itself in the ground.
