Sure shot

You calm yourself and steady your aim. This allows you to take shots you'd never dare to otherwise. 

Make a ranged attack with the weapon used while casting this spell. You gain an additional +3 to hit, and the damage from the attack becomes magical. Roll an additional d8 when determining the damage for this attack.

If you miss by 5 or less, the target takes half the damage that it would've taken if the attack had hit. 

If you hit by 10 or more, the attack is considered a critical hit. If you rolled a natural 20, You may roll an extra 2d8 when determining the damage for this spell.

If you have a feat that allows you to attack multiple times per action, you may make up to that many attacks with this spell's benefits.
