Level 3: Style Points

Starting at fighter 3rd level, your devilish power allows you to harness style and grace with every movement. Your ability to tap into style is represented by a number of style points. Your fighter level determines the number of points you have, as shown by the Style Points column of the Devil Hunter table.

You can spend these points to fuel various stylish features. You start knowing two such features: Stinger and Charged Shot. You learn more stylish features as you gain levels in this class.

When you spend a style point, it is unavailable until you finish a short or long rest, at the end of which your style is replenished a new.

Some of your style features require your target to make a saving throw to resist the feature's effects. The saving throw DC is calculated as follows :

Style Save DC = 8 + your proficiency bonus + your        dexterity​ modifier

Distortion
Your stylish features may use a Distortion die, a d4. This die changes as you gain fighter levels, as shown in the Distortion column of the Devil Hunter table.

Stinger

When you take the Attack action with a melee weapon that you are proficient with on your turn, you can spend 1 style point as a bonus action to move up to 30 feet in a straight line, stopping at the first creature you attack, adding necrotic damage equal to your Distortion die to the damage roll on a hit. This movement does not provoke opportunity attacks.

Charged Shot

When you take the Attack action with a ranged weapon or up to two melee weapons with the thrown property that you are proficient with on your turn, you can spend 1 style point as a bonus action to infuse your weapon with fiendish energy.

You are proficient with it, and you add your Dexterity modifier to its attack and damage rolls. Its damage is force, and its damage die is a d4. This die changes as you gain fighter levels as shown in the Distortion column of the Devil Hunter table.

Attacks made using Summoned Swords do not suffer disadvantage due to being within 5 feet of a hostile creature.
