Trained in ancient breathing techniques that sharpen body and spirit alike, Demon Slayers are warriors forged to fight the creatures that lurk in the dark. Through discipline and relentless practice, they channel their life force into blade and motion, transforming each strike into an expression of pure will. Whether mastering the flames, flowing like water, or moving faster than lightning, a Demon Slayer’s every breath carries the power to destroy evil, and the resolve to face it without fear.

Your breathing style manifests as a powerful named technique. Choose one option matching your style:

• Flame – Blooming Inferno: When you take the Attack action, you can replace one attack with a sweeping fire slash. All creatures in a 15-foot cone must make a Dexterity saving throw (DC = 8 + your proficiency bonus + your Strength or Dexterity modifier) or take 4d8 fire damage (half on success).

• Water – Flowing Torrent: You can move up to your speed without provoking opportunity attacks and make one melee attack at any point during the movement.

• Mist – Vanishing Cut: You can turn invisible until the end of your next turn or until you make an attack.

• Wind – Tempest Fang: When you take the Attack action, you can replace one attack with a slicing gust in a 10-foot-wide, 30-foot-long line. Each creature in the area must make a Strength saving throw (DC = 8 + PB + STR/DEX mod) or take 4d8 thunder damage and be pushed 10 feet away (half damage and no push on a success).
