All Weapons and How to Get Them
1. Slaughter Demon
- Location: Jujutsu Tech – Blacksmith
- Requirement: Purchase with Yen
Slaughter Demon is the earliest weapon most players can access. You can buy it directly from the blacksmith at Jujutsu Tech without needing rare crafting materials. It’s a strong beginner weapon and a solid choice for early leveling because it’s cheap and immediately available.
2. Imperial Sword
- Location: Outskirts NPC (Level 20+ area)
- Requirement: Crafting materials
The Imperial Sword is crafted through an level 20+ NPC found in the outskirts. To make it, you need several materials such as:
- Spirit Wood
- Spirit Infused Wood
- Fire Floater Head Core
- Flying Head Core
It’s a mid-game weapon mainly aimed at collectors or players who want more crafting options.
3. Menus Edge
- Location: Lotus Grave area (open public NPC)
- Requirement: Crafting materials
Menus Edge is obtained from an NPC in the Lotus Grave region. The vendor stands in an open area rather than a hidden cave, making it easier to find once you reach the swamp zone. You’ll need specific crafting drops from enemies in that region.
4. Nanami’s Weapon
- Location: Mizuka Village
- Requirement: Crafting materials
Nanami’s weapon is crafted in Mizuka Village and requires:
- Spotted Sea Pearls
- Mutated Mushroom Core
- Shroom Chief Core
This is a Grade 2 weapon and works well as a mid-game option. It’s not mandatory, but it’s a decent upgrade if you’re farming in the Mizuka region.
5. Jet Black
- Location: Sorcerer Arena entrance
- Requirement: 250 Cursed Essences
Jet Black is one of the more popular weapons because of its design and performance. The NPC is easy to find near the Sorcerer Arena spawn. The main challenge is collecting 250 Cursed Essences, which requires extended farming.
6. Inverted Spear of Heaven
- Location: Outside the main gate near spawn (Maki NPC)
- Requirement: Level 75 + crafting materials
This weapon is locked behind a level 75 requirement. The NPC is located just outside the main gate near the starting area. It’s considered a late-game craft and needs multiple rare materials.
7. Cursed Daggers
- Location: Cursed Cavern
- Requirement: Level 95 + crafting materials
Cursed Daggers are obtained from a level 95 NPC named Mia inside the Cursed Cavern. This area is tied to high-level farming zones and enchantment crystal materials. It’s one of the final NPC weapons you can unlock.
8. Split Soul Katana
- Location: Northwest Shibuya (top-right corner of the map)
- Requirement: Crafting materials
The Split Soul Katana is found through a Maki NPC in the northwest section of Shibuya. This weapon is rarer and not always listed in older resources, making it a hidden gem for players exploring the map.
All Boss Drop Weapons
Some weapons don’t come from NPC crafting and instead drop from world bosses.
1. Blood Scythe
- Dropped by: Eso (World Boss)
The Blood Scythe is a weapon reward from defeating Eso. Since world bosses have respawn timers and competition from other players, farming this weapon can take time.
2. Frost Fangs
- Dropped by: Uraume (World Boss)
Frost Fangs drop from Uraume, another world boss encounter. Like other boss weapons, expect to server hop or wait for respawns while farming.
Collecting every weapon in Roblox Kaizen takes exploration, grinding, and steady progression through higher-level zones. Early weapons like Slaughter Demon help you get started, while late-game gear such as the Inverted Spear of Heaven and boss drops reward dedicated farming. By knowing where each weapon comes from and what materials you need, you can plan your route and avoid wasting time searching the map.
