Jujutsu Kaisen Incremental — Complete Beginner's Guide
Jujutsu Kaisen Incremental is a Roblox idle RPG developed by Real Mouse Productions, inspired by the Jujutsu Kaisen anime. You build a sorcerer through four independent systems: Clan, Cursed Technique (CT), Trait, and Fighting Style. Each is randomly assigned at creation and rerollable later. This guide covers everything you need to know to build efficiently from Grade 4 all the way to Special Grade and beyond.
Full walkthrough covering core mechanics, roll priority, and grade progression.
The Four Core Systems
Every character in Jujutsu Kaisen Incremental is defined by exactly four components. Understanding what each does — and how they interact — is the most important foundation for new players. A strong build isn't just about having a rare CT; it's about all four systems synergizing together. See the full Tier List for rankings.
Clan
Passive BuffsYour bloodline. Provides permanent passive stat bonuses active at all times. Gojo clan gives +50 CE Efficiency and +30 Output — the best for CE builds. Zenin gives +30 Strength and +20 Agility — best for physical builds. Synergy with your CT is critical.
Cursed Technique
Combat IdentityYour active combat abilities. The single most impactful part of your build. Each CT has a unique passive multiplier plus 3–5 moveset slots unlocked through Mastery grinding. Rarity ranges from Common (50%) to Cursed (0.1%). Your CT defines your entire playstyle.
Trait
Permanent ModifierA permanent build modifier that stacks on top of everything else. Six Eyes adds +200 CE Efficiency. Heavenly Restriction trades all CE for +300 Strength and Agility — enabling a completely different physical build path. Black Flash Spark adds +10% Black Flash chance. Traits can completely redirect how a build plays.
Fighting Style
Combat StanceYour combat stance. Each style has a unique base passive and 4 moves unlocked by Mastery. Heavenly Tyrant multiplies all physical damage by 3×. Assassin deals 2.5× against Vulnerable enemies. Jujutsu Sorcerer multiplies CE-based techniques by 2×. Jujutsu Sorcerer + Limitless is the standard CE meta.
Rarity System & Drop Rates
All four systems use the same 5-tier rarity system. These rates apply equally to CT, Clan, Trait, and Fighting Style rerolls. There is no pity system — every roll is independent. Higher rarity always means stronger options, but the jump from Common → Epic is more impactful than Epic → Legendary for most builds.
| Rarity | Drop Rate | Avg Rolls | 90% Chance by | Examples |
|---|---|---|---|---|
| ⬛ Common | 50.0% | ~2 | ~4 rolls | Divergent Fist CT, Basic Clan |
| 🟦 Rare | 30.0% | ~3 | ~7 rolls | Nanami Clan, Shadow Style |
| 🟪 Epic | 15.0% | ~7 | ~14 rolls | Itadori Clan, Taido Style |
| 🟨 Legendary | 4.9% | ~20 | ~46 rolls | Zenin Clan, Sword Draw Iai |
| 🟥 Cursed | 0.1% | ~1,000 | ~2,302 rolls | Gojo Clan, Limitless, Six Eyes |
What to Roll First — Priority Order
Scrolls are scarce in early game. Use the 4 active codes (CULLINGGAME, SP24, BUGS, 1MVISITS) for free rerolls immediately — see our Codes page for the full list. Spend them in this priority order. For reroll math and efficiency, read the Reroll Guide.
Cursed Technique
Min target: Epic (15%) Dream: Limitless / Shrine / Mahoraga (0.1%)CT is your combat identity. A Common CT at endgame will always feel weak. Aim for Epic minimum before Grade 2. Every code you have should go here first.
Trait
Min target: Epic (15%) Dream: Six Eyes (CE) / Heavenly Restriction (Physical)A Cursed-rarity trait completely changes your build's ceiling. Six Eyes + Limitless CT is the #1 CE meta. Heavenly Restriction enables a totally different physical path that can out-DPS CE builds in specific scenarios.
Clan
Min target: Rare (30%) Dream: Gojo (CE builds) / Zenin (Physical builds)Clan bonuses matter but are less decisive than CT tier. Lock in your CT first so you know which stat direction to optimize. Gojo for CE builds, Zenin for physical.
Fighting Style
Min target: Epic (15%) Dream: Heavenly Tyrant (Physical) / Assassin (Burst)Fighting Styles are the most flexible system. The tier gap between styles is smaller than the CT tier gap. Unlock moves through Mastery before judging power — an under-leveled S-tier style can feel weaker than a maxed B-tier.
⚠️ Curse Race — Do Not Select Unless You Know What You're Doing
At character creation, Curse Race appears as an option. Selecting it permanently wipes ALL data — all prestiges, stats, grades, and gear are deleted. In return, you lose all clan passives but gain two unique moves: Cursed Regeneration (4 Mastery, passive regen) and Cursed Metamorphosis (6 Mastery, heal 40% and gain 2× damage for 3 turns). This is a niche build option for experienced players only. Not recommended for beginners or anyone with meaningful progress.
Grade Progression at a Glance
Grades are Jujutsu Kaisen Incremental's primary progression tiers (see Grade System). You start at Grade 4 and advance by accumulating Cursed Energy through combat. Each grade unlocks new enemies, bosses, and tools.
| Grade | Key Unlock | Build Target |
|---|---|---|
| Grade 4 | Starting point — redeem codes here | Reroll CT to Epic+ |
| Grade 3 | Hiromi Higuruma boss (5,000 CE) | Unlock first CT moves via Mastery |
| Grade 2 | Cursed Tools drop system | Equip first Cursed Tool |
| Grade 1 | Raids + Yuta & Naoya bosses | Legendary CT minimum |
| Semi-Special | Ryu Ishigori boss (50,000 CE) | Full Epic+ build all 4 slots |
| Special Grade | Prestige + Mahoraga boss (80,000 CE) | Prestige immediately after unlocking |
CE Farming Tips for Beginners
Cursed Energy (CE) is the core resource. It's your power stat, your currency, and your progression fuel. Here's how to maximize it early:
Idle CE accumulation never stops. Even offline, CE ticks based on your CE Efficiency stat. Log in daily to collect and spend.
Combat CE scales with enemy difficulty. Always push to the hardest enemy tier you can survive for maximum CE per fight.
Jujutsu Sorcerer style's CE Reinforcement (150 Mastery) grants Cursed Surge — boosts both defense and output before big fights.
Bosses give 8–15× more CE per time invested than regular enemies, plus exclusive Cursed Tool drops you can't get elsewhere. See the <a href="/guides/boss-farming-guide/" class="text-violet-400 hover:underline">Boss Farming Guide</a> for routes and HP tables.
Black Flashes randomly multiply CE gain per hit. Traits like Black Flash Spark (+10% BF chance) and Cursed Tools can dramatically increase farm speed.
<a href="/guides/prestige/" class="text-violet-400 hover:underline">Prestiging</a> resets your Grade but permanently multiplies your CE gain. It's the single biggest progression step in the game — don't delay it.

Beginner FAQ
If you have 3+ scrolls, reroll first — a Common CT at max Mastery still loses to an Epic CT at half Mastery. If you only have 1 scroll, grind Mastery while you accumulate more. Don't completely ignore Mastery while waiting to reroll.
CE Efficiency controls how fast you accumulate CE passively (idle income + combat gain rate). CE Output controls how much CE damage your techniques deal in combat. Gojo clan gives +50 Efficiency and +30 Output. For farming speed, Efficiency > Output. For boss damage, Output matters more.
Yes. Curse Race is a permanent character flag set at creation. Even if you reroll your clan using a Clan Scroll, the Curse Race designation and its unique moves remain. The only way to remove it is to delete your character and start over.
Attempt Hiromi Higuruma (Grade 3 boss, 5,000 CE fee) once you have at least one CT move unlocked and your CE output can survive 6–8 turns of combat. For every boss after that, check our <a href="/guides/boss-farming-guide/" class="text-violet-400 hover:underline">Boss Farming Guide</a> for minimum build recommendations before spending the CE entry fee.
Combat requires CE to use moves, but you can still do basic attacks with zero CE. Idle accumulation never stops — you'll regenerate CE over time. With Cursed Regeneration (Curse Race) or the CE Reinforcement move (Jujutsu Sorcerer), you can sustain CE mid-fight better.
