Nemesis

A vow to kill another must be sworn in blood, and held close to an icy heart. When the fire dies, so must one’s mercy.
You declare a challenge, and describe a creature that you have damaged or has damaged you within the past year. That creature becomes marked by your magic, and it feels a sense of impending doom that grows the closer you get to it. You become supernaturally alert towards any sign of your quarry or information that would aid your search, gaining advantage on all checks made to discern the target’s location or path of travel. The first time the target sees you, they must make a Wisdom saving throw. If they fail, they are frightened until the end of their next turn, and must attempt to flee via the safest route they are aware of during their next turn. Once the target has seen you, the spell ends.
