Price +15,000 gp; CL 15th; Aura strong transmutation
A greater transformative weapon becomes any other weapon the wielder desires when a command word is spoken. The weapon cannot become ammunition, but can freely change between simple, martial, exotic, light, one-handed, two-handed, melee, and ranged. The weapon retains all of its enhancement bonuses and weapon special abilities.
However, abilities prohibited by its current shape do not function. For example, a keen greater transformative weapon functions normally in the form of a piercing or slashing weapon, but cannot use the keen special ability when in the shape of a bludgeoning weapon. A double weapon that loses the double quality cannot use the abilities on one of its ends (wielder’s choice), whereas a non-double weapon that gains the double quality applies all its abilities to only one end. When unattended for 1 day, the weapon reverts to its true shape.
