Dead Shot (5e Feat)
From D&D Wiki
You have learned techniques to give you uncanny accuracy against a target you set your sights on. you gain the following benefits:
- Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged attack rolls.
- As an action, you can take aim and focus your attention on a creature you can see, requiring you to start concentrating as if maintaining concentration on a spell. Until you lose concentration, ranged attack rolls you make against the chosen creature have advantage.
