Amulet of the Monster Hunter

While wearing this amulet, you become more keenly aware of the machinations of especially powerful creatures. The amulet comes with a single charge that returns on a short rest. Every other level gained after 10th level, the amulet gains an additional charge, totaling five charges at 20th level.

You can use a reaction, expend a charge, and make a DC 15 Wisdom check to prevent a legendary resistance or legendary action of a creature that you can see.
