I am playing a character who will be undergoing size changes on a regular basis. I am interested in an effect which will make my primary weapon (in this case a bow) always be the correct size that I am currently (in case I end up dropping it while in a size different than natural).
I assume that this kind of ability makes the most sense as a weapon property. As much as I would like it to be a cost based ability like adaptive, but should most likely be an enhancement bonus since thats what most weapon properties are. Since keen is a +1 ability, I feel that this ability would be in-line in terms of power.
Would having adaptive size as a +1 weapon enhancement be balanced/fair? Or is it actually something that exists in Pathfinder already?
While researching this I discovered that there is a sizing weapon property in 3.5 which was a +1 bonus. Only it took a standard action for it to change size.
