Level 15: Autonomous Weapon
As a BA you can split your weapon into as many autonomous copies as you have normal weapons combined. They remain separate for 10 minutes and you can see and hear through them as if you were present. As a BA (included in creation) you can both move them up to 30 ft and have each make an attack individually. They all have all available weapon masteries, attacks, and properties you choose from the original weapon. They count as creatures for the purposes of flanking and opportunity attacks. The weapons have 1 HP but cannot be destroyed when they are within 40 ft of the creator.
