Arcane Tradition: School of PhysimancyPick 1 at 2nd level:
Experimental Self-SurgeryStuff that shouldn't come off does. You have one removable limb or organ (pick: hand, eye, heart, etc). It functions as normal when separated from you and you receive any sensory information it picks up. It can travel a maximum of 100' from you before you are in trouble. (I think I stole this from a GLOG class feature somewhere..)
SomnscribulateAt 2nd level, you can induce sleep in yourself while writing. As you sleep, you write patterns unintelligible to any save yourself. When you finish this sleep (a long rest), you can examine this writing for unconscious physical meaning. Roll two d20 and record the numbers rolled. You can replace any attack roll, saving throw, or ability check made by you or your undead minions with one of these physimancy rolls. You must choose to do so before the roll, and you can replace a roll in this way only once per turn.
Each physimancy roll can be used only once. When you finish a long rest, you lose any unused physimancy rolls.
