Unfailing Precision - Ranger Feature

Unfailing Precision - Additional Ranger Feature - 2nd level

Whenever you make a weapon attack, you can expend one spell slot to empower it. The attack ignores disadvantage and is made with advantage. Furthermore, it scores a critical hit on a 20, 19 or 18 on the d20. The increased critical hit range increases by 1 for each spell level above 1st, to a maximum of 15 (to 17 with a 2nd level slot, 16 with a 3rd level slot and 15 with a 4th level slot). Furthermore, if the attack were to miss, it counts as a non critical hit that deals minimum damage instead.
