Twin Mind

You gain this spell on a roll of 21 or 71 on the Forbidden Spells List.

You and one creature you touch understand each other's thoughts and always know where the other is at for the duration of the spell.  A creature can avoid this effect by succeeding a Wisdom save.  While you are linked you each may cast spells the other has access to, use racial abilities of each other, and have disadvantage on deception checks against one another.
