Palladium Pike

Because the Palladium Pike does 32 damage and the Palladium Sword does 36 damage, you could use a Palladium Pike instead of a Palladium Sword. Despite its appearance, it is a type of spear.

Trivia

 * The Palladium Pike seems to have it's name mixed up with the Orichalcum Halberd, as the Palladium pike has a bladed edge.
