Create Flameskull

You target a skull of a dead wizard in ranged, and bring back a fragment of the wizards consciousness. The target of this spell is transformed in to a Flameskull (The DM has the creatures game statistics). Immediately after creation of the Flameskull you give a directive a number of sentences long equals to twice you spell casting ability modifier. If the Flameskull cannot no longer complete its directive it becomes autonomous, a beholden to no one.
