Project Slayers 2 Best Loadouts: Weapons, Gear and Clans for Every Breathing Style

Project Slayers 2 has a rapidly changing launch-week meta, and current community guides do not always agree on a single universal best build. For example, some current tier lists emphasize Water or Thunder, while others put Thunder, Snake, Insect and Sound at the top.

For a straightforward high-damage setup, use a Duelist-focused gear set with a Dungeon Mask, Bamboo Muzzle, and an appropriate Duelist Haori, then pair it with a Nightfall weapon where your Breathing style allows it.

For Flame, Wind, Thunder, and Water, the Nightfall Katana is a strong general-purpose choice. Stone works best with the Nightfall Axe & Mace, while Sound requires First Light Sound Cleavers. Serpent can use a Nightfall or First Light Serpent Katana, and Insect can use the First Light Insect Katana for its additional utility.

For clans, Rengoku provides a strong damage-oriented setup for Flame, Wind, Thunder, Sound, and Stone. Kocho is suited to Insect, Iguro to Serpent, Tomioka or Urokodaki to Water, and Agatsuma is a strong specialized option for Thunder.

Once your equipment is assembled, finish your Mastery, maximize your relevant stats, and invest in the Additional Damage skill-tree node to complete the build.

Duelist gear setup in Slayers 2

The Duelist Set is the foundation for a damage-focused build. It provides the combination of flat and additional damage bonuses needed to make your weapon and Breathing abilities hit harder.

Dungeon Mask

Use any Dungeon Mask as your headgear. Dungeon Masks belong to the Duelist class, making them an important part of the overall setup.

The specific mask matters less than having the appropriate Duelist equipment, so you can use whichever Dungeon Mask is available to you.

Bamboo Muzzle

The Bamboo Muzzle is the recommended face accessory. It comes from Nezuko and has a low drop rate, so obtaining it can take some farming.

It is particularly valuable when you are putting together a damage-focused Duelist setup and want to keep your accessory slots centered around offensive bonuses.

Flame Haori

The Flame Haori is a useful choice while progressing through the game. It provides a practical option before you have access to the more advanced endgame Duelist Haori choices.

This makes it particularly useful during the transition between mid-game and endgame equipment.

Yoriichi and endgame Duelist Haori

Once you have progressed further, move toward the Yoriichi Haori or another high-tier Duelist Haori.

These options are better suited to a finished damage build, particularly when the rest of your equipment and stats are already approaching their maximum potential.

Nightfall Katana builds

The Nightfall Katana is the main weapon choice for several Breathing styles. Its high damage scaling makes it particularly effective when combined with high stats, Mastery and damage-focused clan bonuses.

Breathing style	Nightfall Katana
Flame	Recommended
Thunder	Recommended
Water	Recommended
Wind	Recommended
Other katana-based builds	Strong general option

Its higher tiers also provide a strong bleed effect, giving the weapon additional damage beyond its initial attack.

For players who simply want a powerful katana-based endgame setup, Nightfall Katana is therefore one of the most straightforward weapons to build around.

Stone Breathing build

Stone Breathing uses a different weapon setup from the standard katana builds.

The Nightfall Axe & Mace is the preferred endgame combination because it provides damage comparable to the Nightfall Katana while also offering additional damage reduction.

This gives Stone players a combination of offensive and defensive value rather than forcing them to sacrifice survivability for damage.

For a Stone build, prioritize the Nightfall Axe & Mace alongside Duelist gear and a damage-focused clan.

Serpent Breathing build

Serpent Breathing benefits from its specialized weapon options.

The Nightfall Serpent Katana or First Light Serpent Katana can provide stronger additional damage-factor scaling than simply using a generic weapon.

This becomes particularly useful as your other stats and bonuses increase. Instead of focusing only on the weapon’s basic attack damage, the specialized Serpent weapon allows the entire build to benefit from its additional scaling.

Pair it with Iguro when building specifically around Serpent Breathing.

Sound Breathing build

Sound Breathing requires the First Light Sound Cleavers, making them the natural weapon choice for this build.

Unlike a standard katana setup, Sound players should build around the cleavers rather than trying to replace them with a generic high-damage weapon.

For the rest of the loadout, use the Duelist gear setup and consider Rengoku when prioritizing general damage.

Insect Breathing build

Insect Breathing has access to the First Light Insect Katana, which provides benefits beyond straightforward attack damage.

Its advantages include movement speed, stamina regeneration and additional stats, making it a useful option for players who value mobility and sustained combat.

For the clan slot, Kocho is the specialized choice for Insect Breathing. This combination allows the build to focus more heavily on the mechanics associated with the style.

If raw weapon damage is your only concern, Nightfall Katana can still be competitive, but the First Light Insect Katana provides additional utility that a purely damage-focused weapon does not.

Volcanic Katana for mid-game progression

You do not need to obtain a Nightfall weapon immediately.

The Volcanic Katana is a strong transitional weapon for players who are still working through mid-game progression. It provides useful scaling while you gather the resources needed for an endgame weapon.

Once you can obtain a Nightfall weapon that fits your build, upgrading becomes the natural next step.

Best Slayers 2 Clans to get based on Breathing Style

• Universal Top Tier – Rengoku: The overall strongest clan for Flame, Wind, Thunder, Sound, and Stone. Provides the highest percentage damage scaling in the game. Note on Flame: Flame Breathing moves require Rengoku to apply the Burn damage-over-time (DOT) effect.
• Second Best Universal – Himejima: High damage scaling, strong counter-ability, and Indomitable Will.
• Style-Specific Clans:
  • Kocho: Best for Insect Breathing (outperforms Rengoku for Insect-specific builds).
  • Iguro: Best for Serpent Breathing.
  • Urokodaki / Tomioka: Best for Water Breathing.
  • Agatsuma: Great alternative budget clan for Thunder Breathing.

Final build combinations for Project Slayers 2

Breathing style	Weapon	Clan	Gear focus
Flame	Nightfall Katana	Rengoku	Duelist
Thunder	Nightfall Katana	Rengoku/Agatsuma	Duelist
Water	Nightfall Katana	Tomioka/Urokodaki	Duelist
Wind	Nightfall Katana	Rengoku	Duelist
Stone	Nightfall Axe & Mace	Rengoku	Duelist
Serpent	Serpent Katana	Iguro	Duelist
Sound	First Light Sound Cleavers	Rengoku	Duelist
Insect	First Light Insect Katana	Kocho	Duelist

Building for maximum damage is about combining every part of your character around the same goal. A powerful weapon alone is not enough. Your Duelist gear, clan, Breathing style, Mastery, stats and skill-tree upgrades should all complement one another.

For general katana builds, work toward Nightfall Katana. Stone players should prioritize the Nightfall Axe & Mace, while Sound, Serpent and Insect players should consider their specialized weapons. From there, match your clan to your chosen style and finish the build by maximizing Mastery and Additional Damage.
