Ultimate Demon Born Breathing Styles Guide: Unlock Every Style in Project Slayers

Master all Demon Born breathing styles in Project Slayers. Learn unlock requirements, upgrade paths, and tips for Water, Thunder, Flame, and more.

Why Breathing Styles Matter in Demon Born

If you're diving into the world of Demon Born breathing styles, you're likely playing Project Slayers, one of the most popular Roblox experiences inspired by Demon Slayer: Kimetsu no Yaiba. Breathing styles are the core combat system that determines how you fight, combo, and deal damage. Without mastering them, you'll struggle against demons and bosses alike.

Understanding Demon Born breathing styles isn't just about knowing which one looks coolest—it's about optimizing your build for the content you want to tackle. Whether you're grinding for Wen, fighting other players, or taking on tough NPC bosses, your breathing style choice and upgrade level directly impact your success rate. Community reports suggest that players who rush to upgrade their lungs see a 40% faster clear time on early-game quests.

What Are Breathing Styles in Project Slayers?

Breathing styles are specialized swordsmanship techniques that rely on Total Concentration Breathing, an esoteric method taught by the Demon Slayer Corps. In Project Slayers, these styles serve as one of the two primary damage-dealing systems (alongside Blood Demon Arts for demons). Each breathing style has unique animations, combo potential, and visual effects that make them distinct.

The game currently features nine breathing styles in Part 1: Water, Thunder, Wind, Insect, Flame, Beast, Mist, Snow, and Sound. Each has its own trainer, unlock requirements, and playstyle. According to player experience, Water and Thunder are considered the best starter options due to their straightforward mechanics and lower cost.

Complete Breathing Style Unlock Requirements

To acquire any breathing style, you must be a human character—demons cannot use breathing styles. The requirements vary depending on which world you're in. Below is a comprehensive breakdown of all unlock conditions.

Starter World Breathing Styles (Part 1)

These styles are available in the first area and require lower levels and Wen. Perfect for new players learning the ropes.

Insect BreathingShinobu KochoButterfly Mansion12+5,000Poison-based damage

If you approach a trainer without meeting the requirements, they will say "Get out of my sight." This applies to all NPC trainers in the game, so make sure you're properly leveled before traveling to find them.

Ouwohana Breathing Styles (Part 2)

Once you reach the Ouwohana area, you'll need significantly more resources to unlock advanced Demon Born breathing styles. These styles are generally more powerful but require grinding.

Breathing StyleLevel RequiredWen RequiredDemon Horns RequiredDifficulty
Flame Breathing75+10,000150Hard
Beast Breathing75+10,000150Hard
Mist Breathing75+10,000150Hard
Snow Breathing75+5,000100Easy
Sound Breathing75+13,000150Very Hard

Based on community reports, Snow Breathing is the easiest to obtain in Ouwohana due to its lower Wen and demon horn requirements. Sound Breathing is considered the most expensive and time-consuming, requiring the highest Wen cost.

Mastering the Breath System

Having a breathing style isn't enough—you must upgrade your lungs to use it effectively. The breath system has five levels, each improving your maximum breath and adding new abilities.

How to Upgrade Your Lungs Efficiently

The upgrade process involves breaking gourds at the Butterfly Mansion. Here's what you need for each level:

  • Strong Lungs: Break 3 large gourds (108 exp), 7 medium gourds (70 exp), and 7 small gourds (21 exp)
  • Total Concentration Breathing: Break 10 large gourds (360 exp)
  • Healing Total Concentration: Break 15 large gourds (540 exp)
  • Complete Total Concentration: Break 20 large gourds (720 exp)

To go from Weak Lungs to Complete Total Concentration Breathing, you'll need a total of 1,800 exp. The most efficient path costs 38,150 Wen using 7 small gourds, 7 medium gourds, and 48 large gourds. If you want exact exp without waste, use 8 small gourds, 12 medium gourds, and 46 large gourds for 39,200 Wen.

Pro tip from experienced players: Prioritize reaching Total Concentration Breathing (level 3) as early as possible. The passive breath regeneration makes a massive difference in combat, allowing you to chain skills without constantly waiting for recharge.

Best Breathing Styles for Different Playstyles

Not all Demon Born breathing styles are created equal. Your choice should match your preferred combat approach.

Beginner-Friendly Options

Water Breathing is the most forgiving style for new players. Its moves have wide hitboxes and decent damage, making it easy to land combos. The trainer, Sakonji Urokodaki, is located in Waroru Cave, which is easy to find.

Thunder Breathing offers the fastest attack speed among all styles. If you prefer hit-and-run tactics, this is your best bet. Jigoro Kuwajima's location on Zapiwara Mountain is straightforward to reach.

According to player experience, Mist Breathing is particularly effective in player-versus-player combat due to its evasive properties. Sound Breathing, while expensive, offers the most complex and rewarding combo potential for skilled players.

Trivia and Hidden Details

Understanding the lore behind Demon Born breathing styles adds depth to your gameplay experience. Here are some interesting facts:

  • Flame Breathing vs. Sun Breathing: Flame Breathing (炎の呼吸 Honō no kokyū) should never be confused with Sun Breathing (日の呼吸 Hi no kokyū). Their pronunciations are identical in Japanese, but they're completely different styles.
  • Visual Effects Are Dramatic: Despite the fiery or watery visuals, breathing styles don't actually create elements. The effects are purely dramatic—except for Moon Breathing and Black Thunder Breathing, which demons use alongside their Blood Demon Arts to make the effects real.
  • Snow Breathing Origins: Snow Breathing is the first fan-made breathing style added to Project Slayers, making it a unique addition not found in the original anime.
  • Sun Breathing Confirmation: Sun Breathing is officially confirmed through the Kamado clan's perks, though it's not a standalone unlockable style.

Frequently Asked Questions

Can demons use Demon Born breathing styles?

No, demons cannot learn breathing styles. Demon Born breathing styles are exclusive to human and Slayer characters. Demons instead use Blood Demon Arts, which have their own unlock requirements and combat mechanics. If you're playing as a demon, you'll need to focus on mastering your Blood Demon Art instead.

What is the easiest breathing style to unlock?

For new players, Water Breathing is the easiest to obtain. You only need level 12 and 5,000 Wen, and the trainer is located in Waroru Cave. For higher-level players in Ouwohana, Snow Breathing is the easiest, requiring level 75, 5,000 Wen, and 100 demon horns—significantly less than other Ouwohana styles.

How much Wen does it cost to max out my breathing?

Going from Weak Lungs to Complete Total Concentration Breathing costs between 38,150 and 39,200 Wen, depending on the gourd combination you choose. This doesn't include the cost of unlocking the breathing style itself, which ranges from 5,000 to 13,000 Wen. Budget at least 50,000 Wen total for a fully upgraded build.

Which breathing style is best for PvP?

Mist Breathing is widely considered the best for PvP due to its evasive maneuvers that make you harder to hit. Thunder Breathing is also strong for its speed. For more information on competitive strategies, check the official Project Slayers Trello board for developer updates and community resources.

Mastering Demon Born breathing styles takes time and grinding, but the payoff is worth it. Choose your style based on your playstyle, upgrade your lungs efficiently, and you'll be dominating demons in no time.
