Juice of the Disintegrating Eye

Disintegrating Eyes. An eyeball bobs in the dark gray liquid of this potion. It vanishes when the potion is opened.   When you drink this potion you have resistance to Force damage for the next 10 minutes. During this time, you can use an action to shoot a magical ray from your eyes at a creature within 120ft. of you that you can see. The creature has to make a Dexterity saving throw (DC 16). On a failed save they take 10d8 Force damage. If this damage reduces the creature to 0 hit points, its body becomes a pile of fine gray dust. If the target is a Large or smaller nonmagical object or creation of magical force, it isdisintegrated without a saving throw. If the target is a Huge or larger object or creation of magical force, this ray disintegrates a 10ft. cube of it. You can use this feature once, only while you are under the influence of the potion.
