KAIZEN on Roblox layers its combat around four interconnected build pillars: weapons, cursed techniques, clans, and fighting styles. Each category spans multiple grades — from Grade 4 starter gear all the way up to Special Grade endgame options — and the gap between the best and worst choices is enormous. Knowing what to grind for (and what to skip entirely) can save you dozens of hours of farming.
Quick answer: The strongest loadout in the current meta pairs the Soul Split Katana (weapon), King Curses or Idle Transfiguration (cursed technique), Heavenly (fighting style), and the Sukuna or Mahito clan for PVE — or Gojo/Itadori/Uraume for PVP.
Weapon tier list
Weapons in KAIZEN are graded from starter-level all the way to Special Grade. The single best weapon is the Soul Split Katana, a Special Grade blade that dominates every other option in both DPS output and mobility. Its key moves — Soul Vortex and Severing Draw — double as gap-closers and combo starters, feeding into Spirit Dissection for massive burst damage. Pairing it with Cryofrost or Straw Doll and the Combo Binding Vow pushes its damage ceiling even higher.
| Tier | Weapon | Grade | Key Strengths |
|---|---|---|---|
| S | Soul Split Katana | Special | Best DPS, best mobility, strong combo starters, pairs with Cryofrost/Straw Doll |
| A | Blood Scythe | 1 | Excellent AOE range, great with Straw Doll stuns |
| A | Frost Fangs | 1 | Ranged poke, combo extender, solid mobility |
| B | Cursed Spear | 1 | Decent single-target boss damage |
| B | Cursed Daggers | 1 | Good mobility support weapon |
| C | Mantis Edge | 3 | Best early-game PVE carry after starter weapons |
| D | Slaughter Demon, Imperial Sword, others | Starter / 2 | Starter-only value; Grade 2 weapons not worth the grind |
The optimal weapon progression path is straightforward: start with Slaughter Demon, jump to Mantis Edge as soon as possible, skip Grade 2 weapons entirely, then farm for Blood Scythe or Frost Fangs. Use either of those Grade 1 weapons to grind for the Soul Split Katana. Grade 2 weapons sometimes deal slightly more damage than Mantis Edge, but the farming time is better spent pushing toward Grade 1.
Cursed technique tier list
Cursed techniques are purchased from the Curse Shop NPC using Yen or Robux. Buying a new technique replaces your current one, so plan your progression carefully. Techniques scale from Grade 4 through Special Grade, and the damage they deal is boosted by the Cursed Energy stat — even though the game's UI doesn't explicitly say so.
| Tier | Technique | Grade | Why It's Here |
|---|---|---|---|
| S | King Curses | Special | Highest DPS in the game; Fuga/Divine Flame and Domain deal massive AOE; best with Sukuna clan |
| S | Idle Transfiguration | Special | Top-2 CT; strong grabs vs humanoids; flexible single-target and AOE; easier to farm than King Curses |
| A | Limitless | Special | Good burst and domain but DPS no longer top-tier after nerfs |
| A | Blood Manipulation | 1 | Great kiting range; strong R move on full hit; requires Choso raid farm |
| A | Finger Bearer | 1 | Best Grade 1 DPS for PVE farming; easier to obtain than Blood Manipulation |
| A | Straw Doll | 2 | Underrated support CT; V move immobilizes for melee/sword combos; rush this early |
| A-/B+ | Shock Amplification | 2 | High PVE farming damage; easy to get; strictly a stepping stone |
| A-/B+ | Cryofrost | 1 | Massive PVP combo potential; strong vs bosses; lower general DPS |
| C | Rot | 1 | Decent PVE rotations but outclassed by easier-to-get Grade 2 options |
| C | Cursed Speech | 3 | Good AOE after rework; outclassed by B-tier and above |
| D | Devil's Broom | 3 | Weak DPS; M1s scale with Weapon stat |
| D | Construction | 4 | Acceptable starter; replace as soon as possible |
| D | Cloning Technique | 4 | Weakest CT in the game |
| D | Boogie Woogie | 3 | Mobility-only niche on melee builds; terrible to focus on |
The recommended CT progression is Construction → Straw Doll → Finger Bearer (optional) → Idle Transfiguration. Idle Transfiguration is strong even without its Domain, making it the better pick if you don't want to farm Domain Shards. If you are willing to grind Domain Shards, King Curses with the Sukuna clan is the absolute ceiling for damage output. To farm a specific advanced technique, you need to clear that technique's corresponding raid — for example, Choso raid for Blood Manipulation or Mahito raid for Idle Transfiguration.
The Kashimo update also introduced Beast Amber, a lightning-based technique with strong combo speed. Early community consensus places it in S-tier alongside King Curses and Idle Transfiguration, though the meta is still settling.
Fighting style tier list
KAIZEN currently has a small fighting style pool, which makes the rankings relatively clean. The late-game choice boils down to Heavenly versus Black Flash, with two earlier styles serving as progression stepping stones.
| Tier | Style | Stage | Notes |
|---|---|---|---|
| S | Heavenly | Late-game | Better combo starter (X) and extender (V) than Black Flash; superior stamina efficiency; V requires Physical Heavenly Restriction binding vow from Toji raid in Shibuya outskirts |
| A | Black Flash | Late-game | Higher raw burst damage per individual move; less sustained combo potential and worse stamina use |
| B | Cursed Fist | Mid-game | Upgraded Divergent Fists; use to farm toward Heavenly or Black Flash |
| C | Divergent Fists | Early-game | Starter style; replace with Cursed Fist when able |
Heavenly edges out Black Flash in most scenarios because its combo extender on V lets you chain more total damage over a fight, and it burns less stamina doing so. Black Flash is the pick if you prefer a burst-heavy playstyle where individual hits matter more than sustained pressure. To unlock Heavenly's V move, you need to roll the Physical Heavenly Restriction binding vow — Binding Vow spins can be obtained through in-game codes and other rewards.
Clan tier list overview
Clans affect your passive bonuses and clan-specific abilities, and the best pick depends heavily on whether you focus on PVE or PVP. For PVE, Sukuna and Mahito are the strongest clans because they synergize directly with the top cursed techniques (King Curses and Idle Transfiguration, respectively). For PVP, Gojo, Itadori, and Uraume offer better utility. One important caveat with Sukuna in PVP: the clan ability has noticeable animation lag that opponents can punish, so it requires careful timing.
Stat and progression tips
The Cursed Energy stat boosts cursed technique damage, which is not obvious from the in-game tooltip. If you're running a CT-focused build, prioritize this stat. You can reset your stats using Stat Purity Tokens, which drop from chests, bosses, world bosses, and the AFK World — or can be purchased with Robux.
For a weapon-focused build, the ideal late-game setup is Soul Split Katana paired with Straw Doll (for immobilization combos) or Cryofrost (for freeze combos and PVP control). Combine that with Heavenly as your fighting style and the Combo Binding Vow for raw damage amplification.
KAIZEN's meta shifts with each major update, and the recent Kashimo patch is a good example of how new techniques can shake up the rankings. Regardless of what changes, the core progression philosophy stays the same: skip intermediate grades whenever possible, rush toward the strongest options in each category, and invest your farming time where the power ceiling is highest.
