Magic Weapon Abilities - Extending

An extending weapon can alter its length to add or subtract 5 feet of reach. Once per round as a free action, the wielder of an extending weapon can make the weapon assume a length 5 feet longer or shorter than its normal length. The wielder must state, at the beginning of her turn, whether the weapon extends or shortens. Melee weapons can be turned into reach weapons to threaten foes 10 feet away, but when extended, the weapon no longer threatens foes within 5 feet of the wielder. Reach weapons can be set to threaten targets 5, 10, or 15 feet away. If set for 10 feet, the reach weapon no longer threatens adjacent foes, and if set for 15 feet it no longer threatens opponents 5 or 10 feet away. The extending property can only be added to Large hafted melee weapons (anything except a sword), flails, chains, whips, and similar weapons.
