Expert Sniper (5e Feat)
From D&D Wiki
Prerequisites: Int of 16 or higher, Proficiency in Firearms
You have learned where is the best part to hit a target, and how to hit it. This grants you the following benefits:
- When using ranged attacks, instead of using dexterity to hit, you can use intelligence. If you do this, you can add your intelligence to the damage roll.
- As an action, you can carefully line up your next shot. The first ranged weapon attack you make on your next turn has advantage and ignores half cover and three-quarters cover. If it hits, it is a critical hit. You lose this benefit if you move or are forced to move before making this attack on your next turn.
- Being prone doesn't impose disadvantage on your attack rolls with ranged weapons.
