Jujutsu Kaisen Incremental — Status Effects Guide

Status effects in Jujutsu Kaisen Incremental are buffs and debuffs applied during combat through specific moves, passive traits, or Cursed Tool procs. Understanding every status effect — what it does, what applies it, and how to synergize or counter it — is the difference between a good build and an optimized build. See also Boss Farming Guide and Fighting Styles. Data sourced directly from the official developer Trello (meowtheturtle).

Detailed Breakdown

🔴

Vulnerable

Debuff · Duration: 2–4 turns

Target takes increased damage from all sources. Applies to physical, CE, and DoT damage equally.

Sources
Assassin — Shadow Strike (50 Mastery, 2t)Heavenly Tyrant — Brutal Takedown (50 Mastery, 4t)Brawler — Manji Kick (500 Mastery, 2t)Assassin — Phantom Image (500 Mastery, combined with Weakened)
Synergy

Assassin's passive deals 2.5× to Vulnerable targets — the highest single-hit multiplier in the game. Apply with Shadow Strike then use your 3 strongest moves. Standard Mahoraga kill strategy.

Counterplay

Block (70% DR) partially mitigates amplified damage. High Endurance stat reduces the effective amplification.

🩸

Bleed

Debuff — DoT · Duration: 2–5 turns

Deals damage at the start of each of the target's turns. Damage scales directly with the applicator's CE Output stat.

Sources
Sword Draw Iai — Quick Draw (50 Mastery, 2t Bleed)Sword Draw Iai — Flash Step Slash (400 Mastery, 5t Bleed)Assassin — Throat Slit (400 Mastery, 4t Bleed)Rika's Arm (Cursed Tool — applies 3t Bleed on every hit)
Synergy

Gojo clan +30 Output amplifies every Bleed tick. Stacking Flash Step Slash (5t) + Rika's Arm proc = extended Bleed windows. Essential damage source during Mahoraga's adaptation windows when direct damage is reduced.

Counterplay

No Bleed cleanse mechanic. Block reduces the initial hit but doesn't stop DoT. Vitality investment is the only mitigation.

Stun

Debuff — Hard CC · Duration: 2–5 turns

Target cannot perform any action. Queued moves are cancelled. Complete turn skip.

Sources
Brawler — Divergent Fist (50 Mastery, 2t)Brawler — Ground Slam (150 Mastery, 3t)Kempo — Seven-Star Rush (350 Mastery, 5t)CE Trait Electricity — 25% chance on any attack
Synergy

Brawler chain: Divergent Fist (2t Stun) → Ground Slam (3t Stun) = 5 consecutive turns of CC. Resets Naoya's Momentum stacks. Pairs with CE Electricity trait for passive proc uptime.

Counterplay

Bosses have reduced Stun duration (~50% effectiveness). No complete stun immunity, but boss resistance makes CC less reliable in endgame.

💨

Evasion

Buff — Self · Duration: 1–4 turns

Increases dodge chance for the duration. Dodged attacks deal zero damage.

Sources
Heavenly Tyrant — Air Walk (400 Mastery, 4t Evasion)Assassin — Vanish Step (150 Mastery, 4t Evasion)Kempo — base +10 dodge rate passive (always active)Shadow Style passive — Simple Domain costs 0 CE (enables Evasion-CE hybrid)
Synergy

Kempo passive +10 dodge stacks with Vanish Step for very high sustained avoidance. Critical for surviving Ishigori's CE Discharge and Mahoraga's high-damage turns.

Counterplay

Pierce status completely bypasses Evasion. Pierce attacks always connect regardless of dodge rate. Evasion-heavy builds are hard-countered by Pierce sources.

🗡️

Pierce

Status Override · Duration: Instant — applies to the triggering hit only

The triggering attack ignores both Evasion (always hits) and Block (deals full damage, not reduced).

Sources
Rock Cannon (Cursed Tool — drops, pierces on crit hits)Kempo — Iron Palm (150 Mastery, ignores defense on hit)Certain CT passive effects
Synergy

Hard counter to Evasion/Block defensive builds. Rock Cannon + crit build = consistent Pierce procs that bypass all defensive stats. Best-in-slot boss damage tool at endgame.

Counterplay

No direct counter to Pierce. Don't rely solely on Evasion/Block as your defensive strategy if enemies can proc Pierce.

🟣

Cursed Surge

Buff — Self · Duration: Until consumed or fight ends

Increases both CE Output (damage) and Defense simultaneously. Applied as a combat buff.

Sources
Jujutsu Sorcerer — CE Reinforcement (150 Mastery, applies Cursed Surge)Sword Draw Iai — Godspeed Impulse (650 Mastery, applies Cursed Surge)Status Effect passively triggered by CE-based build conditions
Synergy

The go-to pre-fight buff for CE builds. CE Reinforcement before engaging a boss gives both damage and defense for the fight duration. Godspeed Impulse applies it at high Mastery for Sword Draw Iai builds.

Counterplay

N/A — self-buff, no counterplay needed.

🛡️

Block

Defensive Action · Duration: Applies to the blocked hit only

Reduces incoming damage by 70% (85% for Martial Arts style). Not a status effect but a core defensive mechanic.

Sources
Available to all characters — default actionMartial Arts passive: Block mitigates 85% instead of 70%Sword Draw Iai — Sheath Counter (200 Mastery, grants Block + counter if timed)
Synergy

Essential against Higuruma's Deadly Sentencing (turns 3 & 6) and Ishigori's CE Discharge. Martial Arts + Block = near-complete damage mitigation, enabling CE accumulation while taking hits.

Counterplay

Pierce ignores Block entirely. Against Pierce sources, Block provides no damage reduction.

🔥

Momentum

Stacking Buff · Duration: Until consumed by attack or fight ends

Stacks with consecutive actions. Each stack increases the next attack's damage by a multiplier. Also used by Curse: Naoya boss — his stacks become deadly by turn 5+.

Sources
Heavenly Tyrant — Wall Run Strike (150 Mastery, grants 3 Momentum stacks)Naoya's Fist Wraps (Cursed Tool — grants Momentum stack on every hit)Curse: Naoya boss gains Momentum every turn automatically
Synergy

Naoya's Fist Wraps + Wall Run Strike = rapid Momentum stacking before a finisher move. Best for physical builds. Against Naoya boss: Stun him to reset his Momentum before stacks reach dangerous levels (turn 5+).

Counterplay

Stun resets Momentum stacks — CC-based strategies neutralize Naoya boss completely.

⬇️

Weakened

Debuff · Duration: 3–5 turns

Target deals reduced damage on all attacks for the duration.

Sources
Assassin — Phantom Image (500 Mastery, applies both Weakened + Vulnerable)Judge's Gavel (Cursed Tool — applies Weakened on hit)
Synergy

Weakened + high Endurance build = near-zero incoming damage window. Use Phantom Image on Mahoraga to dramatically reduce his damage output during adaptation phases.

Counterplay

Bosses with Adaptation (Mahoraga) adapt to repeated Weakened application — 3+ consecutive Phantom Image uses reduce its effectiveness.

🌑

Evasion (Shadow)

Passive Buff · Duration: Passive — always available at 0 CE

Shadow Style's Simple Domain ability costs 0 CE — unique passive that enables CE-free Evasion activation.

Sources
Shadow Style fighting style passive (always active)
Synergy

Shadow Style is the only style that can trigger its Evasion mechanic with zero CE, making it uniquely strong for CE-depleted survival situations. Combine with Vanish Step for layered avoidance.

Counterplay

Pierce still bypasses this like all other Evasion sources.
