Fighter Subclass – Thunder Breathing

Lightning-fast movement, pinpoint accuracy, and explosive force define Thunder Breathing. A practitioner moves like a flash of lightning—silent one moment, devastating the next. To face them is to be struck before you even realize the fight has begun.

Thunderclap Step

You can strike faster than the eye can follow.

• When you take the Attack action, you can teleport up to 10 feet to an unoccupied space you can see before or after each attack. This movement does not provoke opportunity attacks.

• You may only use this teleport once per attack.

Flash Counter

Your reflexes crackle with reactive power.

• When a creature misses you with a melee attack, you can use your reaction to immediately move 5 feet and make one melee weapon attack against them.

You can use this feature a number of times equal to your Dexterity modifier (minimum 1), regaining all uses on a long rest.

Piercing Bolt

Your strikes tear through defenses with focused precision.

• Once per turn when you hit with a melee weapon attack, you can deal an extra 1d8 damage.

• If the target is surprised or hasn’t acted yet in combat, the damage increases to 2d8, and the attack automatically scores a critical hit on a natural 19–20.

Blinding Dash

You become a blur on the battlefield.

• When you take the Dash action, you may make one melee weapon attack at any point during your movement.

• This attack is made with advantage, and the target must succeed on a Strength saving throw (DC = 8 + your proficiency + your Dex mod) or be knocked prone.

Storm Reflexes

Your reaction speed borders on precognition.

• You gain +2 to initiative rolls, and opportunity attacks against you are made with disadvantage.

• Additionally, you can make two reactions per round, but only one per turn.

Final Form: Thunderclap and Flash – Sixfold

You vanish in a streak of pure speed.

• As an action, choose up to six creatures within 60 feet that you can see.

• You teleport in a flash between them, making one melee weapon attack against each target.

• Each hit deals extra 3d10 lightning damage, and targets must succeed on a Constitution saving throw (DC = 8 + your proficiency + Dex modifier) or be stunned until the end of your next turn.

You can use this feature once per long rest.
