- Thunder Breathing is widely considered an S-tier style for burst damage and PvP mobility in Slayer 2.
- Learn it from the Thunder Trainer (Jigoro Kuwajima-inspired NPC) after completing his quest and paying the unlock fee.

- Best paired with a Standard Katana and stamina-efficient clan passives.
- Commit to one path early — switching styles later requires significant investment.
Thunder Breathing Overview: Why It Is S-Tier
Thunder Breathing is the fastest, most aggressive Slayer style in Project Slayers 2. It trades area coverage for raw burst: nearly every move closes distance instantly, which makes it the go-to pick for players who want to end fights in a single combo. Community tier lists consistently rank it in S-tier thanks to its dash cancels, unmatched PvP mobility, and one-shot potential against under-leveled opponents.
Unlike Wind or Insect Breathing, which favor chip damage and area denial, Thunder rewards precision. You commit to a strike, burst in, and either finish the target or reset. That high-risk, high-reward rhythm defines the style's learning curve.
| Stat | Thunder Breathing | Rating |
|---|---|---|
| Burst damage | Highest among Slayer styles | ★★★★★ |
| PvP mobility | Dash cancels, instant gap-close | ★★★★★ |
| Farming speed | Single-target focused, slower on groups | ★★★☆☆ |
| Skill floor | Requires combo timing and stamina management | ★★★★☆ |
| Best weapon | Standard Katana | ★★★★★ |
Thunder Breathing suits players who like aggressive, execution-heavy combat. If you prefer safe ranged pressure or group farming, Wind or Temari-based builds may fit better.
How to Unlock Thunder Breathing: Step-by-Step
Thunder Breathing is learned from the Thunder Trainer, a Jigoro Kuwajima-inspired NPC located at his training grounds on the map. You must reach the required level, complete the trainer's questline, and pay the unlock cost in Wen before the style becomes available.
| Requirement | Details |
|---|---|
| Trainer NPC | Thunder Trainer (Jigoro-inspired location) |
| Level gate | Reach the required level first |
| Quest | Complete the trainer's questline |
| Cost | Pay unlock fee in Wen |
| Weapon | Standard Katana recommended |
| Race | Human (Slayer path) only |
Level Up in the Starting Village
Farm low-level bandits and starter demons near the spawn hub. Always accept quests before farming — quest rewards stack on top of kill XP and are the fastest early-game progression.
Save Enough Wen
Do not spend early currency on cosmetics. The Thunder Trainer charges a unlock fee in Wen, and arriving under-funded means a second farming trip.
Find the Thunder Trainer
Locate the Jigoro-inspired trainer on the map. Trainers are scattered across the world, unlocked through exploration and the fast-travel system.
Complete the Trainer Quest
Finish the trainer's quest objectives. Expect combat trials against mid-tier enemies — bring healing items and manage stamina.
Pay the Fee and Learn the Style
Pay the unlock cost to receive Thunder Breathing. Assign your new moves to number slots 1–4 before your next fight.
Switching breathing styles later requires significant investment. Try each trainer's preview or watch gameplay before locking in Thunder as your main style.
Thunder Breathing Moveset and Combos
Every Thunder move is built around instant acceleration. Here is the confirmed moveset and how to chain it.
| Move | Type | Best Use |
|---|---|---|
| Thunderclap and Flash | Signature dash strike | Gap-close, combo starter, PvP opener |
| Sixfold | Multi-hit follow-up | Burst damage after a landed opener |
| Rice Spirit | Multi-strike attack | Mid-combo pressure |
| Thunder Swarm | Finisher | Closing out stunned or exhausted targets |
Burst Opener Combo
- Thunderclap and Flash to close
- M1 string for chip damage
- Sixfold before the target recovers
Execute Combo
- Dash in with M1s
- Rice Spirit for stagger
- Thunder Swarm to finish
PvP Punish Combo
- Wait for enemy attack whiff
- Thunderclap and Flash punish
- Full M1 into Sixfold cancel
Exhausted players cannot block, dash, or use skills. Thunder combos burn stamina fast — leave enough in the bar to dash out if a combo drops.
Best Builds and Clan Synergies
Your clan passives shape how Thunder Breathing performs. Because Thunder already delivers damage, prioritize clans that improve stamina efficiency, breathing regeneration, or sword damage.
| Clan Tier | Chance | Synergy with Thunder |
|---|---|---|
| Common / Uncommon | ~90% combined | Fine for leveling; re-roll with spare spins |
| Rare | ~7% | Dash/block stamina efficiency pairs well with burst play |
| Legendary | ~2% | Sword damage and faster breathing regen amplify combos |
| Mythical (Kamado / Tsugikuni) | ~1% or lower | Top-tier damage multipliers, best-in-slot |
Thunder Breathing Milestones:
- Reach the level gate and save the unlock fee in Wen
- Complete the Thunder Trainer questline
- Learn all four moves and assign them to skill slots
- Land a full Thunderclap and Flash into Sixfold combo in PvP
- Re-roll for a Rare or better clan with stamina or sword passives
Invest in attack first, then stamina. Thunder wins fights in the first two seconds — extra health matters less than the ability to keep dashing.
Thunder vs Other Breathing Styles
Thunder leads the meta for PvP, but it is not the best tool for every job. Compare it against the other confirmed styles before committing.
| Style | Tier | Strength | Weakness |
|---|---|---|---|
| Thunder | S | Fastest burst combos, dash mobility | Weak area coverage for group farming |
| Water | A | Balanced moveset, reliable finishers | Lower ceiling than Thunder in PvP |
| Wind | B | Strong area damage for farming | Punishable wind-ups in PvP |
| Mist | B | Confusing repositioning tech | Low raw damage output |
| Insect | C | Poison damage over time | Slow kills, outclassed in PvP |
For mob farming runs, Wind or Shockwave-style area tools clear groups faster. Many players keep Thunder for PvP sessions and farm with area styles on alternate characters.
