Crystal Ball of Ominous Portent
Source: Arcana Unleashed - Deadfall
Wondrous Item, Legendary (Requires Attunement)
Black-and-scarlet clouds of ominous magic swirl inside this crystal orb. While touching the orb, you can cast Hex or Scrying (save DC 17) with it.
In addition, when a creature you can see within 60 feet succeeds on a D20 Test, you can take a Reaction to turn the roll into a 1. Once used, this property can’t be used again until the next dawn.
