Witches’ Eye
Wondrous item, very rare
Price: 20,000-60,000 gp | medium sentimentality
Commonly mistaken for witches, hence the misnomer, this eye actually comes from a coven of hags that share the eye to see the strands of destiny. If you’re missing an eye, placing the eye in your eye socket allows you to see using the eye. The eye has darkvision up to 120 feet, and you can use an action to observe a creature up to 60 feet away to see how many hit points it has.
Paid
Once a day, while holding the eye, you can use an action to cast the scrying spell without its material components requirement and with a DC of 20 for the target’s Wisdom saving throw.
Overpaid
The scrying spell’s target’s Wisdom saving throw DC is 25 instead of 20.
