This small magic slab allows you to essentially remove an obstacle or enemy in your way. 

While attuned to this slab, you can speak its magic word, Vanessaril, to essentially erase an object or living thing.  Upon speaking the slabs magic word, it starts to glow a bright white light.  Choose a target, if its an object, roll a d20 and if you roll a 13 or higher, the object gets teleported to a different location of the DMs choosing on the same plane of existence.  If the target is a living creature, they have to make a wisdom saving throw of DC 16.  If they fail the saving throw, they get plane shifted to a random place on a random plane of existence of the DMs choosing.  If they succeeded the save, they can't be targeted by the slab for d10*20 days.

The slab has 3 charges per day. At the start of a new day, the slab regains all expended charges. You must expend a charge to use it.  If the slab drops to 0 charges, roll a d20. On a 1 the slab crumbles into dust is permanently destroyed.
