Animate Graft (3.5e Spell)

Looks like Luke Skywalker is suffering from an acute case of Alien Hand Syndrome.

As you cast this spell, choose a graft the target has equipped. If it is an internal graft, they get a +2 bonus on their Will save. On a failed Will save, the graft animates and begins attacking its owner immediately, not stopping even when the owner is killed, although you can command the graft to grapple or deal nonlethal damage instead, if it's external.

If it's an external graft, it can use the unarmed strike attack of its owner, any weapons it's holding, and any attacks the graft itself grants, although its attack bonus is equal to your caster level plus one of your mental ability modifiers, and it doesn't get any bonuses to damage granted by class features, feats, or morale bonuses. The graft can also attempt to grapple its owner, using its owner's own grapple check modifier with a -4 penalty.

If it's an internal graft, it shifts around, destroying the target's other internal organs. This deals 1d2 points of Constitution damage per round.

Animated grafts have hit points equal to twice your caster level, and AC equal to 20 plus one of your mental ability modifiers, as well as any damage reduction, regeneration, fast healing, and similar abilities granted by the graft itself. Damage dealt to an internal graft is also dealt to the target. A missed attack directed at the graft automatically hits the target instead. An attack can only be directed at the graft if the target is willing.
