Potion of Clairvoyance

When you drink this potion, you gain the effect of the clairvoyance spell. An eyeball
bobs in this yellowish liquid but vanishes
when the potion is opened.
You create an Invisible sensor within range
in a Location familiar to you. The sensor
remains in place for the duration, and it
can't be attacked or otherwise interacted
with. You can see and hear through it.
