Fighting Style Focus

This is an optional class feature for Fighters, Paladins, Rangers and any other base class that gains a fighting style.
It becomes available at the same level that the class gains a fighting style.

In battle, you use your training and discipline to outmatch your opponents.
On your turn, you can enter a focused state as a bonus action.

While focused, you gain a benefit based on your fighting style, if you have multiple fighting styles, you choose one to focus on.

Archery

If you miss an attack with a ranged weapon you gain advantage on your next attack with a ranged weapon against the same target before the end of your next turn.
You can only gain advantage in this way once per round.

Defense

You can add half your proficiency bonus, rounded down, to any saving throw you make that doesn’t already include your proficiency bonus.

Dueling

When you are wielding a versatile weapon in one hand and no other weapons, you roll for damage as though you were using the weapon two-handed.

Great Weapon Fighting

Once per turn, when you roll the maximum on weapon damage dice for an attack you make with a melee weapon that you are wielding with two hands, you can roll one additional weapon damage die and add it to the attack's damage. The weapon must have the two-handed or versatile property for you to gain this benefit.

Protection

When a creature you can see attacks a target other than you that is within 15 feet of you, you can use your reaction to move up to 10 feet towards the target.
If you end this movement within 5 feet of the target you impose disadvantage on the attack roll and the target gains temporary hit points equal to your proficiency bonus.
You must be wielding a shield.

Two-Weapon Fighting

If you miss with the off-hand attack from two-weapon fighting you can use your reaction to immediately make another weapon attack against the same target.

Blind Fighting

Your blindsight range increases to 30 feet and you gain advantage on Wisdom (Perception) checks that are not based on sight.

Interception

When a creature you can see hits a target, other than you, within 5 feet of you with an attack, you can use your reaction to swap places with the target, changing the attack's target to you. This movement does not provoke opportunity attacks.
You reduce any damage you take from the attack by 1d10 + your proficiency bonus (to a minimum of 0 damage).

Superior Technique

Whenever you use the Maneuver gained with this Fighting Style, you can roll a d4 and use it instead of expending a Superiority die.

Thrown Weapon Fighting

Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged attack rolls with thrown weapons.
Additionally, your ranged attacks with thrown weapons ignore half cover.

Unarmed Fighting

If you aren’t wielding any weapons or a shield you gain a +1 bonus to AC.
Additionally, when you successfully Shove a creature of your size category or smaller that you are grappling, you can choose to move that creature to any unoccupied space within 5 feet of you before pushing it or knocking it prone.

You can maintain your fighting style focus for up to 1 minute or until your concentration ends (as if you were concentrating on a spell).

Once you have used your fighting style focus you cannot use it again until you finish a long rest.
