Ambusher’s Regret

1st-level evocation

Casting Time: 1 reaction, which you take when you are hit by a ranged attack from an attacker you can’t see

Range: 120 feet

Components: S

Duration: 1 round

You release an arcane arrow that traces the path of the triggering attack back to your unseen attacker, provided the attacker is in range. That creature must succeed on a Dexterity saving throw or be outlined in light until the end of your next turn. While outlined in light, the creature sheds dim light in a 10-foot radius, any attack roll against it is made with advantage if the attacker can see the creature, and the creature can’t benefit from being invisible.
