Project Slayers 2 Update 1 landed on November 14, 2026 — and it hit like a Hashira at full strength. The new level cap, two fresh Breathing styles, brand-new Blood Demon Arts, a whole fishing profession, and a world boss leveling method players are calling flat-out broken. If you've been grinding the same Kasugai Crow loop and wondering why the game feels stale, this is the patch that changes everything. This Project Slayers 2 Update 1 guide covers exactly what you need: the fastest route to Level 400 using the Hairo boss method, where to unlock Beast and Flower Breathing in Dusk Web Hollow, and a step-by-step walkthrough for getting the Capture Cavity BDA from the Hairo nighttime event.
⚡ Quick Answer
In Update 1, the fastest way to reach Level 400 is farming Hairo — a world boss that gives 5 guaranteed levels per kill. Beast and Flower Breathing trainers are both in Dusk Web Hollow. Capture Cavity BDA drops from the Hairo nighttime event at Duskweb Hollow Shrine (100,000 cost, 5% drop rate).
What Does Project Slayers 2 Update 1 Actually Change?
This isn't a small balance patch. Update 1 is the kind of content drop that reshuffles how every player builds, grinds, and fights. Here's the core of what arrived:
- Level cap raised to 400 — with a path to 450 via Hinokami Embers
- Beast Breathing and Flower Breathing — both tied to Dusk Web Hollow
- Capture Cavity and Thread — two new Blood Demon Arts
- Spider Mountain raids — multi-difficulty PvE with boss tiers
- Full fishing profession — Angler rank system capping at 30
- Base stats tree overhaul — full point refund for all players
- New crit system — crits deal 50% extra damage, displayed in orange with !
- Sun damage nerf for demons — down to 1% max HP every 2 seconds
- Extended buff timers — 2x Luck now 45 min, 2x Wen now 30 min
- Weapon transfer system — reforge one weapon's tier and level onto another in its set
What Is the Fastest Way to Reach Level 400 in Project Slayers 2?
Kasugai Crow quests still work. But Hairo laps them entirely. This world boss at Dusk Web Hollow is currently the most efficient leveling method in the game — and once you see the numbers, you'll understand why the community went wild over it.
📊 Key Stat: Hairo spawns every 3 hours and stays active for 30 minutes. He gives 5 guaranteed levels per kill. That's roughly 15 levels per 30-minute window — or 30 levels with 2x XP active. Through server hopping, players are stacking 45–90+ levels a day.
The Hairo Boss Leveling Method — Step by Step
- Navigate to Dusk Web Hollow: Open the map UI and head to the Shrine area and central clearing inside Dusk Web Hollow. Hairo's spawn point is marked on-map.
- Deal at least 10% damage: You must hit the 10% damage threshold to qualify for rewards and chest drops. In a packed public server this is easy — in a quieter one, make sure you're contributing before the boss dies.
- Server hop immediately after the kill: Hairo's 30-minute window means active servers stack up. Jump to a fresh server the moment he drops on yours.
- Stack 2x XP for maximum returns: With 2x XP active, 15 levels per window becomes 30. The free-to-play option is 2x XP (30 minutes) for 14 Ores from the in-game shop — far cheaper than the Robux equivalent.
I'll be honest — when I jumped in right after launch, about 400 players were crammed into the Hairo zone and it was pure chaos. His health had scaled to 50,000 HP before I could get a clean opener in, and I didn't even get a screenshot. After switching to a quieter server and running it with a friend — bringing him to 35,000 HP — we were stacking 10 levels a session before the timer ran out. The 3-hour respawn sounds punishing, but server hopping completely breaks that gate open.

💡 Pro Tip: Don't fight Hairo in packed public lobbies. His HP scales to 50,000 with four players present — a solo Hairo is only 15,000 HP. Use a private server or bring exactly one friend (35,000 HP, still fast) for the cleanest farming loop.
Where Are the Beast and Flower Breathing Trainers in Project Slayers 2?
Both new Breathing styles are gated inside Dusk Web Hollow — the new region that opened up with Update 1. They're the most-discussed additions across the community right now, and for good reason.
🐗 Beast Breathing
The Beast Trainer is located inside Dusk Web Hollow. To unlock the ultimate tier of Beast Breathing, you need a Hashira Inosuke drop — specifically the mythic beast katana and mythic board head. It's a chaotic, aggressive style that suits players who like to stay unpredictable in PvP.
🌸 Flower Breathing
The Flower Trainer sits in the same region — Dusk Web Hollow. For the ultimate tier, you're chasing a Hashira Kanao drop, which yields the Ozman/mythic flower tuzono. It's the precision counterpart to Beast's chaos: controlled, flowing, and deadly in its own right.
⚠️ Important: Rumours are circulating about combining Beast and Water Breathing into a hybrid style. Data miners have already confirmed this is not possible in the current patch. Don't invest time chasing something that doesn't exist.
How to Get Capture Cavity BDA in Project Slayers 2 Update 1 (Full Steps)
Capture Cavity is Hairo's signature Blood Demon Art — and getting it involves a full mini-event with a strict countdown, a boss fight with scaling HP, and a 5% drop rate on the orb. Here's exactly what to do:
- Travel to Duskweb Hollow Shrine: Open your map and navigate to the Shrine area inside Duskweb Hollow. The Shrine costs 100,000 to access.
- Find the Hairo NPC — only at night: This is the step most players miss on their first attempt. The event and the NPC interaction only triggers during the in-game nighttime cycle. Come back during the day and nothing happens.
- Kill 10 wolves in a circle: Once you trigger the event at night, a ring of wolves spawns nearby. Take down all 10 before moving on to the next phase.
- Defuse 5 dynamites in 2 minutes and 50 seconds: Five dynamites spawn roughly 100–200 meters apart across the area. On-screen arrows point you toward each one. The timer is strict — don't stop to fight anything you don't have to.
- Fight Hairo: His health scales by player count. Solo: 15,000 HP. Two players: 35,000 HP. Four players: 50,000 HP. If you're strong enough, solo is fastest.
- Check your archives for the orb: The Capture Cavity Orb has a 5% drop rate. It appears as a clouded orb that smells of smoke and wet fur. Crush it in your inventory to begin Capture Cavity core training.
| Players in Hairo Event | Hairo's HP |
|---|---|
| Solo | 15,000 HP |
| 2 Players | 35,000 HP |
| 4 Players | 50,000 HP |

⚠️ Important: Public servers at launch are a disaster for this event. Random players flooding the zone scale Hairo to 50,000 HP and can interrupt the wolf and dynamite phases. Farm this on a private server for consistent, controllable runs.
Other Update 1 Changes That Are Worth Your Attention
Free Stat Tree Reset
All previously spent stat points are being refunded. The old system is gone — replaced by a new base stats tree with passives built in. Take the time to plan your allocation before sinking points, since the meta is freshly shifted by the new crit system.
New Critical Hit System
Critical hits now deal 50% extra damage, shown in orange with an exclamation mark mid-combat. Crit Resistance is a new defensive stat that counters this. At Tier 3, attacks also cut healing by 30% — a significant PvP consideration that changes how you build defensively.
Sun Damage Nerfed — Demons Rejoice
Sun damage dropped from 3% of max health every 1.3 seconds to 1% of max health every 2 seconds. Standing under a roof now completely blocks it. Demon players can finally engage in outdoor fights without burning down in seconds — this was one of the most requested balance changes in the community.
📊 Key Stat: Buff timers received a major quality-of-life improvement: 2x Luck now lasts 45 minutes (up from 15), and 2x Wen runs for 30 minutes (up from 15). Stacking these before a Hairo farming session makes a measurable difference in rewards per hour.
Fishing Profession
Project Slayers 2 now has a full fishing system. The Angler rank caps at 30 and is shared across all characters on your account. Three boss fish surface every 2 hours for high-value drops, and completing fish log pages rewards titles and fishing gear. The Angler Node skill item is craftable at Angler Rank 20. It's not essential for combat progression, but it's a decent passive income stream while waiting for boss respawns.
"Refinement raises its success chance at that level, so climbing to plus 10 always gets easier — that is absolutely beautiful."
Frequently Asked Questions
Where are the Beast and Flower Breathing trainers in Project Slayers 2 Update 1?
Both trainers are inside Dusk Web Hollow, the new region added in Update 1. The Beast Breathing Trainer teaches Inosuke's combat style, and the Flower Breathing Trainer teaches Kanao's. For their ultimate tiers, you need Hashira drops from Inosuke and Kanao respectively — mythic items that unlock the highest-tier movesets.
What is the max level cap in Project Slayers 2 after Update 1?
The base level cap is 400 in Update 1. Players can extend progression to 450 by using Hinokami (Heno Kami) Embers, a special item that unlocks the final tier of the level track. Developer notes confirm this extended cap is intentional — 450 is the current maximum.
What is the drop rate of the Capture Cavity Orb, and how do I farm it reliably?
The Capture Cavity Orb has a 5% drop rate from the Hairo Event. Because the drop is RNG-based, repeated farming is expected. Using a private server lets you fight Hairo at 15,000 HP solo rather than 50,000 HP in a crowded public lobby, making each attempt faster and less frustrating.
How often does Hairo spawn, and how do I get Spider Mountain raid tickets?
Hairo spawns every 3 hours and remains active for a 30-minute window. Spider Mountain raid tickets are earned by defeating the Spider World Boss. Once you have tickets, you can queue for Spider Mountain in easy, medium, or hard difficulty — each tier offers different boss encounters and loot rewards.
How has sun damage changed for demons in Update 1?
Sun damage was reduced significantly — from 3% of max health every 1.3 seconds to 1% of max health every 2 seconds. Additionally, standing under a roof now completely blocks all sun damage. Demon players operating outdoors have meaningfully more survivability and time to engage in extended fights.
Bottom Line: Update 1 Is Exactly What This Game Needed
Project Slayers 2 Update 1 earns its hype. The Hairo boss leveling method alone — 5 guaranteed levels per kill, server-hoppable, stackable with 2x XP — is genuinely the most efficient grind route the game has ever had. Beast and Flower Breathing give Hashira fans an immediate reason to push into Dusk Web Hollow, and the Capture Cavity BDA grind, while punishing on public servers, is a satisfying reward for those who run it correctly with a private lobby. Stat points are refunded, buff timers are more generous, demons got a real quality-of-life improvement with the sun damage nerf, and the fishing system gives you something to do while waiting on boss timers. Prioritize Hairo first, plan your stat tree before you allocate, then work your way into the breathing unlocks. The race to 400 is on.
