Animate Siege Weapon (EFA - A)

You imbue an otherwise non-magical and inanimate siege weapon, such as a ballista, mangonel, or battering ram, with a semblance of life. For the duration, on your turn the siege weapon attacks whatever you command it to. You can give it a new command as long as you are within range. You can also command it to allow itself to be operated normally. The siege weapon can operate itself as if it were operated by a trained crew. It automatically succeeds on any checks required to operate it.
