What is the best breathing style in Slayers 2?

There is no settled answer after the v.09 patch. Pre-patch lists put Thunder alone in S tier, but v.09 added roughly a second of release delay to its Z, X, C and V skills and cut God Speed to normal running speed. Post-patch rankings place Flame and Wind above Thunder and often put Serpent first.

What level do you need for breathing styles in Slayers 2?

Level 25 is the gate for every breathing trainer, and you must physically walk to the trainer who teaches the style you want. There is no menu that hands you a moveset.

Can you change your breathing style in Slayers 2?

Yes. The Shop sells Reset Breathing for 100 Robux, but the same reset sits on the Ore tab for 7 Ore, which is farmable from chests and quest turn-ins. Resetting clears the style but not the next trainer requirements.

Is Thunder Breathing still good after the nerf?

It remains playable. Its damage and its Flaming Thunder God ultimate are unaffected by v.09, but its mobility was reduced and its approach can now be perfect blocked, so it sits in the strong-alternative band rather than the meta band.

Slayers 2 Breathing Style Tier List

This tier list ranks the eight trainable breathing styles in Slayers 2 as of the v.09 balance patch. It is built from published rankings and patch notes rather than from my own testing — see the honesty note at the bottom for exactly what that means for each row.

Tier List at a Glance

Tier	Style	Best used for	One-line verdict
S	Serpent	PVP	Teleport plus a knock-up opens fights on your terms, though conservative lists still say it needs more testing.
A	Flame	PVE	Buffed in v.09, it clears packs with wide reach and burn once paired with the Rengoku clan.
A	Wind	PVP	v.09 cut its startups to 0.12–0.18s and removed Whirlwind Cutter knockback, letting V start combos.
A	Sound	Group PVE	Nearly every move extends into another, and its projectile hits hard on its own.
A	Insect	PVP and PVE	Fast moves that link with little effort, with barrages as the payoff.
B	Thunder	PVP	Still hits hard with an untouched ultimate, but v.09 slowed its core skills and gutted God Speed.
B	Stone	PVP	Hyper armor on almost every attack, at the cost of slower combos and a longer counter cooldown.
C	Water	Grinding	Buffed in v.09 with a 0.35s strict stun on tapped X, but still the lowest damage of the eight.

Reading the tiers honestly: the gap between S and B here is narrower than the letters suggest. Most of it comes down to how fast a move starts up and how reliably it chains into M1 attacks, not to raw damage numbers.

What actually decides a style’s tier

Three things separate these kits, and they explain almost every placement on this page:

Startup speed — how long between pressing the key and the attack coming out. This is what the v.09 patch changed most.
Combo chaining — whether moves extend into each other and into basic M1 attacks, or leave you in recovery.
Area coverage — how much of a pack a kit clears at once, which only matters in group PVE.

Version-sensitive placements

Training Requirements

Every style is gated behind level 25 and a physical trip to its trainer — there is no menu that hands you a moveset. These are the costs published as of September 2026:

Style	Trainer	Where	Cost
Water	Urokodaki	Underground cave, Bamboo Grove	5,000 Wen, 30 Demon Horns
Flame	Rengu	Rooftop past the Mistfall bridge	10 Demon Horns
Serpent	Obari	Cliffside above Windy Peak	20 Demon Horns, 5 Beast Cores
Wind	Sanemi	Frozen water, Iceveil Valley	50 Demon Horns
Thunder	Zentaro	Tallest mountain peak	Level 25
Sound	Tengai	Cliff above Frost Veil Shrine	Wall Climb required
Stone	Gyomei	Near Hidden Mist Village Shrine	Axe and Mace
Insect	Shinora	Butterfly Estate rooftop	Level 25

Costs and unlock thresholds are early-access figures and can shift between updates — read the trainer’s own dialogue before committing to a long farm. For the leveling route that gets you to 25, see the beginner guide.

Method and sources

This page is a compilation of published research, not first-hand testing. Where sources disagree, both numbers are shown with their dates rather than averaged into a false consensus:

Style costs and trainer locations follow the Slayers 2 breathing trainer guide (updated September 19, 2026).
The pre-patch tier arrangement follows the breathing style tier list (September 19, 2026), which placed Thunder alone in S and Wind and Water in C.
The post-patch re-ranking and all v.09 numbers follow the Thunder Breathing nerf analysis (September 21, 2026).
Reset mechanics and the 7 Ore cost follow the breathing reset guide (September 21, 2026).

Rows still marked [TBD]

[TBD] Exact damage values for any style — no source publishes reproducible dummy benchmarks.
[TBD] Whether Serpent genuinely holds the top spot, or whether that is early patch reaction.
[TBD] Post-v.09 combo routes for Thunder, which the source itself calls unsettled.
[TBD] Demon-side equivalents — breathing styles are exclusive to the slayer side of the game, so this list does not apply if you play a demon.

Frequently Asked Questions

Should I reset a style I already trained?

Only if the style you are leaving is one of the ones v.09 actually hit. Thunder kept its damage and its ultimate, so the source’s own advice is that spending materials to change styles for this patch is unnecessary. If you do switch, buy the reset for 7 Ore rather than 100 Robux — see the codes page for free Wen and Spins to fund the rest.

How confident should I be in this list?

Treat it as a map of the current sources, not as a tested ranking. Nothing here is first-hand — the placements are compiled from published guides and patch notes, and the sources disagree with each other on the top of the list. The v.09 numbers are quoted directly, but the tiers built on top of them are judgments drawn from those numbers. Verify a style in-game before spending a long farm on it.

TL;DR

Safest pick right now: Flame for PVE (cheap at 10 Demon Horns, buffed in v.09) or Serpent for PVP.
Still fine, no longer dominant: Thunder — damage and ultimate intact, mobility and approach gutted.
Re-check first when the balance pass lands: Water and Wind, the two styles v.09 buffed most.
Before you commit: confirm the trainer’s current cost in-game, and use the beginner guide to reach level 25 first.
