True Seaking Shot

You brandish the weapon used in the spell’s casting and make a ranged attack with it against one creature within range of the weapon. You gain advantage on this attack roll. On a hit, the creature takes extra damage equal to your spellcasting ability modifier of the weapon's type.

This spell’s critical hit range increases when you reach certain levels. At 5th level, the critical hit range increases by 1 (19-20). The critical hit range increases further by 1 at 11th level (18-20) and 17th level (17-20). This bonus combines with any other feature that increases the critical hit range.
