Martial Tactician

General Feat (Prerequisite: Level 4+, Martial Weapon Proficiency)

You gain the following benefits.

Ability Score Increase. Increase your Strength, Dexterity, or Constitution score by 1, to a maximum of 20.

Advanced Tactics. You can take the Help action as a Bonus Action. Additionally, when you take the Help action to assist an attack roll, the distance from which you can distract an enemy is increased to 30 feet.

Impactful Retaliation. When a creature within 30 feet of you uses their reaction to make an Opportunity Attack, you can give the creature a bonus to the attack and damage roll of the attack. This bonus is equal to the Ability Score modifier increased by this feat. 

Word of Warning. When another creature within 30 feet of yourself who can hear you makes a saving throw, you can use your Reaction to grant that creature Advantage on the saving throw, as you call out a warning before they succeed or fail.

Once you use this benefit, you can’t do so again until you finish a Short Rest or Long Rest.
