Eldritch Sight

By being born from an arcane bloodline or for augmenting yourself with mechanical parts, your sense of sight gets a boost after you feel pain by developing an arcane target aim. You point at the creature who hits you from a close range of 30 ft. with your index and pinky fingers in a gesture of being watching, causing your arcane eye lock mechanism to activate, causing your eyes to shine in a color of your choice during the duration of the spell.
Until the spell ends, either as a bonus action of yours or because you lose concentration, you gain advantage on saving throws and rolls on spells and attacks. You will not be able to attack other opponents while focused on an enemy, or you will lose your concentration. If the creature goes away from your sight and beyond 30 ft., you lose track of that creature and your eye mechanism goes off, and the spell ends.
