Slayer 2 Update 1 is a massive update, and there is quite a lot to explore if you are returning to the game. We now have the Mt. Natagumo Spider Raid, two new Breathings, additional Evil Arts, new areas, fishing improvements, bounty hunting, faction activities, and plenty of equipment to collect.
I wanted to put everything together in one place because some of these additions are connected. For example, you will need Raid Tickets to enter the Spider Raid, while other activities help you earn Wen, EXP, Mastery, and new equipment. There are also several changes to character stats and weapon compatibility that you should check before jumping into the new content.
In this guide, I will walk you through the important features of Update 1, including the new codes, raid rewards, level progression, Beast and Flower Breathing, fishing, factions, and balance changes. If you are trying to catch up or decide what to farm first, this should give you a good starting point.
Slayer 2 Update 1 Guide – Spider Raid, Level 450, Codes
There is a lot of new content, so I recommend starting with the changes that affect your character before spending time farming.
Here is the order I would follow:
- Open your character stats and distribute your refunded points through the new Base Stats tree.
- Check your main weapon and make sure it is compatible with your current build.
- Travel to Duskweb Hollow and work on Beast or Flower Breathing.
- Defeat the Spider World Boss to collect Raid Tickets.
- Enter Mt. Natagumo during the Spider Raid opening.
- Complete daily quests, use the Daily Wheel, and work on whichever progression system you prefer.
You do not have to complete everything immediately. I would focus on getting your character ready, unlocking the new abilities, and then farming the raid for its equipment.

Beast Breathing, Flower Breathing and New Evil Arts
Two new Breathings arrive with Update 1: Beast Breathing and Flower Breathing. Both have their own trainers in Duskweb Hollow, and each comes with a matching Hashira boss and Mythic weapon.
Beast Breathing
Beast Breathing is built around dual-wielding two katanas. If you enjoy aggressive combat and want a different weapon style, this is one of the new abilities worth checking out.
You can learn it from the Beast trainer in Duskweb Hollow. The associated Inozu boss drops the Beast Breathing ultimate, Mythic Beast Katanas, and the Mythic Boar Head.
Flower Breathing
Flower Breathing is the second new option. Its attacks use flowing flower-themed slashes, giving it a different combat feel from Beast Breathing.
Visit the Flower trainer in Duskweb Hollow to begin learning it. Defeating Kanao can reward you with the Flower Breathing ultimate and Mythic Flower Katana.
New Evil Arts
There are also two important additions for Demon players:
- Thread Evil Art: Obtain it from Ruo’s raid chest. V1.01 also adds Thread Orb to Muzan.
- Capture Cavity Evil Art: Obtain it by defeating Hairo.
One useful detail is that you do not need to repeat the entire training process if you switch abilities later. After completing the training for a Breathing, Blood Demon Art, or Fighting Style, its trainer can teach it to you again for free.
New Clans
Update 1 introduces three new clans:
| Clan | Rarity |
|---|---|
| Hashibira | Supreme |
| Ayaki | Supreme |
| Tsuyuri | Mythic |
Mt. Natagumo Spider Raid: How to Enter and What You Get
The Spider Raid is one of the biggest additions in Update 1. It takes you through Mt. Natagumo, where you will face several spider bosses and work toward earning new accessories, runes, and other rewards.
You can enter through the Spider Raid portal during the first 10 minutes of every hour. Each player needs one Raid Ticket to join.
If you are looking for tickets, start with the Spider World Boss. On V1.01 servers, defeating it rewards three Raid Tickets.
Spider Raid Bosses
The raid takes you through several encounters:
- Mother Spider
- Brother Spider
- Father Spider
- Ruo
Each boss has its own attacks, mechanics, and cutscenes, so you should not expect every encounter to play out the same way.
You can choose between Easy, Medium, and Hard difficulty. Easy adjusts to your party size and is possible to complete solo. If you are farming for better rewards, Hard is worth considering because it offers improved reward chances.
A Hard clear also pays 152,000 Wen.
Spider Raid Rewards
The boss chests contain 17 new accessories, including the Mythic Tengu Wings. You can also collect Raid Runes from the spider bosses.
Runes are useful because they provide additional character stats. You can equip up to three at once, and Mythic Runes also come with a passive effect.
If you get a rune you do not want, visit the Rune Keeper. You can use this NPC to reroll or break your runes.
Another helpful change is that nearby bosses now have separate health bars. Cast bars also show which ability a boss is preparing, making it easier to react before an attack lands.
Spider World Boss
The Spider World Boss is a separate activity from the raid. It supports up to 20 players and appears once every three hours.
Its chests have five reward tiers and contain 14 new pieces of equipment, with rewards reaching Mythic rarity.
V1.01 makes this boss easier to fight by reducing its damage to half of its previous value. Its health scaling is also reduced by 5,000 per player.
Boss Rush
Boss Rush is another activity you can try if you prefer fighting bosses rather than completing the full raid. This mode is solo-only and gives you two runs per day.
You will fight multiple bosses one after another. Defeated bosses return as echoes while you continue through the remaining encounters.
Level 450 Progression and New Areas
Update 1 increases the normal level cap from 225 to 400. You can push it further to level 450 by using Hinokami Embers.
The character progression system has also changed. Instead of relying on the old stat allocation system, you now have a new Base Stats tree with additional passive options. Previously spent stat points are refunded, so make sure you check your allocation before continuing your grind.
New Leveling Areas
Two new areas are included in this update:
| Area | New bosses |
|---|---|
| Duskweb Hollow | Dokuro and Kaganu |
| Iceveil Valley | Kibaro, Kumado and Utsushi |
These areas cover progression from levels 225 to 450. You can explore their quests and bosses while working toward the new level cap.
Hairo World Boss
Hairo is another important boss to farm in Duskweb Hollow. To bring him out, you need to defeat the wolves and complete his TNT objective.
His rewards include levels, Wen, Ore, and 15 accessories. Some of these accessories belong to his own critical-hit equipment set.
V1.01 reduces Hairo’s health scaling to 10,000 per player, making the encounter less demanding for larger groups.
Across the Spider World Boss, Spider Raid, Hairo, and the new zone bosses, Update 1 introduces 58 accessories and outfits.
Daily Quests and Daily Wheel
There are a couple of new daily activities that are worth adding to your routine.
- Daily Quests: You can complete three quests per day starting at level 10. Completing all three gives an additional bonus.
- Daily Wheel: Available from level 35, this gives you one free spin each day through the main menu.
I would recommend completing these regularly because they give you another way to make progress without spending all your time farming bosses.
Critical Hits and New Stats
Critical hits are now part of character combat. A critical attack deals 50% additional damage and appears in orange with an exclamation mark.
You can also build Critical Resistance to reduce the chance of an opponent landing a critical hit against you. Critical Damage is another stat added with the update.
Crow Missions and Nizen Hunts
Crow missions and Nizen hunts have also received a useful change. Their rewards are personal, meaning you can receive your full reward without having to worry about other players taking a share.
Some boss hunts can now ask you to defeat two bosses or a group of enemies in exchange for a larger payout.
Update 1 also adds 36 new titles across its content.
Ouwigahara: New Climb Tree and 107 Tokens
If you regularly play Roguelike mode, you will want to check the changes to Ouwigahara.
The total rewards from a complete climb have increased by approximately 30%. You can now earn 107 Tokens for a full climb instead of the previous 82.
The new total replaces the earlier reward milestone breakdown, so the update does not provide a revised individual payout for every floor.
Climber Rank and Climb Tree
You can now earn Climber Rank and points by progressing through the tower. These points are used in a new five-path Ouwigahara Climb Tree.
The tree includes progression options such as starting deeper into the tower, which can make future runs more convenient.
There is also a new Roguelike season with another collection of limited items available through the shop racks.
If you are unfamiliar with this mode, check our Tower Mode guide for preparation tips, cards, and rewards.
Fishing Update: Angler Rank, Boss Fish and Mythic Rods
Fishing has received a much bigger role in Slayer 2. It is no longer just a simple activity where you cast a rod and wait for a catch. Every fish now has a fight mechanic.
When the bobber goes underwater, you need to strike at the right moment. After hooking a fish, keep the reel inside the green area and react to its movements. Stronger fish can use additional moves, so you will need to pay attention rather than simply holding the fishing button.
Angler Rank and Fishing Skills
Angler Rank now goes up to level 30 and is shared across your characters. As you progress, you earn points that can be spent in the Fishing skill tree.
The new Professions page also gives you access to your Fish Log and weekly fishing records.
If you do not want to manually handle every catch, you can use Auto Angler by holding your rod’s button.
Nushi Boss Fish
Nushi introduces three boss fish that take turns appearing every two hours.
Defeating one together with other players rewards you with:
- Wen
- Angler XP
- A trophy
- A title
These encounters are worth checking regularly if you want to level up your Angler Rank and collect additional rewards.
Mythic Fishing Rods
Once you reach Angler Rank 20, visit Angler Runo to craft two Mythic rods.
| Rod | Main use |
|---|---|
| Bloodmoon Rod | Catching large fish |
| Tidecaller Rod | General fishing and farming |
There are several other fishing improvements as well. Rare fish sell for more Wen, completing individual Fish Log pages gives you titles, and you can find 12 different pieces of fishing gear while fishing.
Bounty Hunting and Village Capturing
Update 1 adds more activities for players who enjoy fighting other players or working toward faction-related rewards.
Bounty Hunting
To start bounty hunting, speak with the Mercenary and request a mark. Your objective is to hunt players with the opposite reputation inside a shrinking storm zone.
Winning earns Bounty Medals, while losing can reduce your reputation.
As you increase your Hunter Rank, you receive points for the new Bounty skill tree. You can also work through contracts and compete on the weekly Most Wanted board.
The Mercenary’s shop lets you exchange Bounty Medals for several rewards, including:
- Hunter accessories
- Ore
- Rune Dust
- EXP
- Wen
- Mastery
Village Capturing
Village capturing is available to Evil Spirits at level 100 or above.
You need to raise a flag in a village and defend it against Slayers. Successfully holding the area rewards you with EXP, Wen, Mastery, Ore, and chests.
This gives Demon players another way to progress while taking part in PvP activities.
Faction System: Levels, Store and Battles
Factions now have a larger progression system. Members work together to earn faction EXP and unlock shared benefits.
The faction leader can choose which upgrades the group should focus on, so the progression is not entirely individual.
Faction Store
The Faction Store includes 18 exclusive pieces of equipment. You purchase these items using faction contribution.
One important detail is that faction equipment is stronger than other equipment of the same rarity, making it worth working toward if you are part of an active faction.
Faction Boss
You can also challenge a daily Faction Boss with up to four faction members.
The boss is a large oni, and defeating it rewards a Faction Boss Chest.
Faction Battles
Faction Battles let members join their team from any server and fight against another faction.
Each side can have between 3 and 15 players, so you can take part in smaller fights or larger group battles.
Other faction features include:
- A Faction Reputation board showing the top 50 factions.
- Custom faction tags containing 2–4 letters.
- Shared faction progression and leader-controlled upgrades.
New Weapons, Fist Guards and Weapon Variants
One of the biggest weapon changes affects Demon players. Every Demon now receives Fist Guards as their main weapon.
Fist Guards and Beast Katanas come in three versions:
- Damascus
- Firstlight
- Nightfall
Kanabo and Kusarigama also receive Damascus, Nightfall, and Poison Parasol versions.
Weapon Transfer Tickets
Weapon Transfer Tickets let you change a Firstlight or Nightfall weapon into another weapon from the same set.
The useful part is that your weapon keeps its existing tier and refinement after the transfer.
V1.01 fixes Weapon Transfer Ticket usage on mobile. If you are switching your weapon back, use the Update1Reforge3 code.
There are a few more weapon-related changes to understand:
- You can only carry one main weapon on your toolbar.
- The supported main weapon types include Katana, Axe, Mace, and Fist Guards.
- Switching a sub weapon does not remove your unlocked skills.
- You can use any weapon you own as the appearance of another weapon.
- Evil Art skills work with Gauntlets, Claws, Sickles, and War Fans again on V1.01.
Poison Parasol and Halloween Event
The Poison Parasol variants give you another reason to collect weapon materials.
You can use Venom Vials to convert Firstlight or Nightfall equipment into its Poison Parasol counterpart.
At Tier 3, hits from these pieces reduce the opponent’s healing by 30%. This can be particularly useful when fighting players who rely heavily on healing.
Trick or Treat Event
The Halloween event takes place at night in Lanternrest Village.
Look for the costumed children and complete Trick or Treat interactions to collect candy. You can then spend the candy at Kabocha’s shop.
The event shop contains 20 Halloween items and the Pumpkin Rune.
Refinement Changes, Boosts and Ranked Rewards
Refining equipment is more forgiving after Update 1 thanks to a new pity system.
Whenever an attempt fails, the item’s chance of succeeding at that refinement level increases. This means repeated failures gradually improve your odds instead of leaving you with the same chance every time.
Auto Refinement
The Refiner now has an Auto tab where you can configure your refinement process.
You can select a target refinement level, set Wen and Guard limits, and check the expected cost before starting.
This is useful if you are trying to refine several pieces of equipment without manually repeating every step.
Longer Boost Durations
Two familiar boosts have received longer durations:
| Boost | Previous duration | New duration |
|---|---|---|
| 2× Luck | 15 minutes | 45 minutes |
| 2× Wen | 15 minutes | 30 minutes |
These longer boosts make it easier to spend time farming without constantly activating another boost.
Ranked Season 2 Rewards
You can claim Ranked Season 2 rewards through the Ranked Board in the main menu.
The rewards are cosmetic, account-wide, and tradable. From Season 2 onward, ranked rewards also provide more Wen and Ore, along with Refinement Guards.
The Roguelike board provides Ouwigahara Tokens.
If you earned the same reward through multiple rankings and did not receive every copy, V1.01 fixes this issue. Rejoin the game to receive the missing rewards automatically.
Storage, Trading and Other Quality-of-Life Changes
There are several smaller additions that make everyday gameplay more convenient.
Item Locking and VIP Storage
You can now lock items to prevent them from being sold, deleted, or traded accidentally.
VIP Storage adds a shared 40-space storage box that can be accessed across your characters.
The new Cosmetics page also brings vanity items and titles together. You can save loadouts and toggle cosmetic effects when you want a cleaner appearance.
Helper Box Gamepass
The Helper Box gamepass allows you to carry another player on your back.
It also protects the carried player from sunlight and lets them earn half of your EXP, Wen, and Mastery.
Trade Hub
The Trade Hub gives players a place to exchange equipment, materials, and cosmetics face to face.
You need a verified account or one month of VIP to enter.
More Small Changes
Here are some other additions and adjustments worth knowing:
- Arena voting: Players can vote for the map before each fight.
- Muscular Horse: A rare wild horse with improved speed and stamina. You can tame it and then purchase it for 50,000 Wen.
- Dash keybind: You can change the dash key in Settings. Q remains the default.
- Snow’s cold damage: Cold damage is reduced from 3% of Max Health every 1.3 seconds to 1% every 2 seconds. Standing under a roof prevents the damage.
V1.01 Changes: What Was Fixed?
V1.01 brings several useful fixes and adjustments after the main Update 1 launch.
Here are the changes I would pay attention to:
- Evil Art skills work again with Gauntlets, Claws, Sickles, and War Fans.
- Mobile Weapon Transfer Tickets work again.
- Use
Update1Reforge3when switching weapons back. - The Spider World Boss now awards three Raid Tickets.
- Spider World Boss damage is reduced by 50%.
- Spider World Boss health scaling is reduced by 5,000 per player.
- Father Spider deals less damage during the raid.
- Hairo’s health scaling is reduced to 10,000 per player.
- Thread Orb is now available from Muzan.
- Quest EXP is doubled up to level 400.
- Missing duplicate Ranked rewards are automatically delivered after rejoining.
If you are still seeing older behavior, make sure you have joined an updated server.

There is a lot more to do in Slayer 2 now, especially if you have already reached the previous level cap. The Spider Raid gives you a new reason to farm bosses, while Beast and Flower Breathing provide fresh options for players who want to change their builds.
I would start with the Base Stats reset, unlock the new abilities you are interested in, and then work toward the Spider Raid and its Mythic rewards. Once you have a build you are happy with, fishing, bounty hunting, factions, and Ouwigahara give you plenty of other ways to keep progressing.
The V1.01 changes are also worth checking because they fix weapon compatibility and make several progression activities more rewarding. Whether you are returning for the new level cap or just want to collect the new gear, Update 1 gives you plenty of reasons to jump back into Slayer 2.
