EDIT: I would like to use my Channel Divinity on the first attack. Increasing the attack by 10 for a to hit roll of 18.

Channel Divinity: Guided Strike

Starting at 2nd level, you can use your Channel Divinity to strike with supernatural accuracy. When you make an attack roll, you can use your Channel Divinity to gain a +10 bonus to the roll. You make this choice after you see the roll, but before the DM says whether the attack hits or misses.
