True(r) Strike

With a pointed finger and a determined mind, you hone in on your target's weaknesses. For the duration, your first attack roll against the target on each of your turns gains advantage, as your magic gives you uncanny insight into their defenses.

Additionally, if your attack hits, it deals an extra 1d4 damage of the same type as the attack.

The spell ends if you target a different creature with it, if the target drops to 0 hit points, or if the spell's duration ends.
