Endaris' True Strike

When you attack a creature with a weapon, your magic grants you a brief insight into the target's defenses. You make a melee or ranged attack against one creature within range, using your spellcasting ability for the attack and damage rolls.

On a hit, the target suffers the weapon attack’s normal effects, additionally, the target must succeed a Wisdom saving throw. On a fail, you gain advantage on your next attack roll against the target, until the end of your next turn.

A target that fails the save is immune to this saving throw, when you cast the spell again, until the end of your next turn.
