R: Touch D: [dice] x 10 minutes

You summon the ghostly memory of a whole body that was once attached to a skull. It will be somewhat helpful to you and retain the approximate intelligence of the creature it had in life, but none of the memories. It can attack with its skull as a heavy weapon and can fit through any space that its skull can fit through. It only has 1 HP but is attacked with disadvantage.

If you invest 4 dice or more in this spell, the effect becomes permanent.
