So I have a player that wants to create or have it created for his character (who is a barbarian) a new weapon quality that he and another player sort of outlined. Basically he wants the benefits of the Longarm spell as a weapon quality but can only be used for a certain number of rounds per day with a lesser and greater version. The Lesser version would only attack as the masterwork version of the sword in the extra reach squares and the greater would match all the benefits of the weapon. In fluff he sees it as an phantom or energy blade extending out of the weapon and should be limited to spears and sword like weapons as well. I don’t think it really needs such a limit and don’t see anything wrong with it. I mean if Longarm wasn’t a personal spell I just say buy potions or make a wand but as this isn’t an option I figure take a good look at the possibility of such a quality which I think includes peer review. So, this is what I have so far.
Extending, Lesser (Could be a better name): An extending weapon is able to create a phantom extension of itself when wielded upon its users need. Three times per day, as a swift action, the weapon‘s threat range extends by 5 feet until the start of the wielder’s next turn. Any attacks in the extended reach are treated if the weapon was only masterwork plus any material qualities it might have.
Extending, Greater: A Greater Extending weapon shares the same qualities as lesser except they gain access to five times per day and treat attacks at the extended range with all the qualities of the enchanted weapon.
