Tactician

3rd-Level Ranger Feature

Beginning at 3rd level, your tenacity can wear down the most powerful of foes. You gain one of the following features of your choice. Art of War. Your skill in combat with hordes allows you to move through numbers without fear of reprisal. During your turn, when you make a melee attack against a creature, you don’t provoke opportunity attacks from that creature for the rest of the turn, whether you hit or not.
Giant Killer. When a Large or larger creature within 5 feet of you hits or misses you with an attack, you can use your reaction to attack that creature immediately after its attack, provided that you can see the creature.
Horde Breaker. Once on each of your turns when you make a weapon attack, you can make another attack with the same weapon against a different creature that is within 5 feet of the original target and within range of your weapon.
Marksman. Being within 5 feet of a hostile creature doesn't impose disadvantage on your ranged attack rolls. Also, when a hostile creature's movement provokes an opportunity attack from you, you can use your reaction to make a ranged weapon attack as opposed to a melee weapon attack.
