How to Beat EX9 and EX10 Bosses in Jujutsu Kaisen Phantom Parade

To consistently clear the challenging EX9 and EX10 stages in the Jujutsu Kaisen Phantom Parade Shibuya Incident story arc, you must move beyond standard rotations and optimize your team specifically for massive burst damage. These encounters feature bosses with health pools exceeding 20 million, effectively acting as DPS checks that punish slow, attrition-based playstyles. By focusing your roster on breaking these high-HP thresholds through precise ultimate management and buff stacking, you can bypass the lethal mechanics these bosses deploy once their health drops below critical percentages.

Understanding the EX9 Boss: Kurisaka Jiro

The battle against Kurisaka Jiro is a test of your ability to maintain consistent damage output while managing the boss’s unique defensive cycles. Kurisaka Jiro does not merely sit still; he periodically buffs his own defenses, which can stall a team that relies on chip damage.

Strategy for Success:

• Focus Fire: Avoid splitting damage between secondary adds. Your sole priority is the boss. If your damage is spread thin, you will fail to meet the DPS check required to end the fight before Kurisaka Jiro’s ultimate attacks overwhelm your team.
• Buff Alignment: Never fire your ultimates in a vacuum. Wait for your support units to apply "Damage Taken Increase" debuffs or "Team Attack Up" buffs.
• Memory Card Choice: If you find the boss surviving with a sliver of health, you are likely using defensive Memory Cards. Swap these for aggressive cards that provide percentage-based increases to your DPS unit’s critical damage or ultimate power.

Mastering the EX10 Boss: Shigemo Haruta

Shigemo Haruta in the EX10 stage represents a significant step up in complexity. This boss utilizes a defensive gauge mechanic that mitigates incoming damage significantly if you attack at the wrong time. The primary mistake players make is firing off their ultimate abilities the moment they become available.

Execution Tactics:

• The Burst Window: Observe the boss's defensive gauge. When the gauge is at its lowest, the boss is vulnerable. This is the only time you should unleash your full chain of ultimate abilities.
• Debuff Timing: Characters capable of removing or ignoring defensive buffs are invaluable here. If your team lacks this utility, you must rely on massive raw damage to force your way through the mitigation.
• Patience: It is better to wait one extra turn for your support’s cooldowns to refresh than to waste a full rotation on a shielded boss. Timing your burst in the final phase of the fight is essential to surviving the boss's end-game enrage mechanics.

Optimized Team Composition and Synergy

For high-HP boss encounters in Jujutsu Kaisen Phantom Parade, a balanced team is insufficient; you need a hyper-focused "Hypercarry" composition.

The Core Roles

1. Main DPS: Select a character with high scaling on their ultimate ability. Ideally, this unit should have self-buffing capabilities that trigger upon using skills.
2. The Enabler (Buffer): Your buffer must provide either team-wide attack scaling or turn-manipulation (Speed buffs). Increasing your turns per round is the most effective way to reach the 20 million damage threshold.
3. The Debuffer: This unit is non-negotiable for EX10. Look for characters who can reduce the enemy's defense or increase the damage they receive. This acts as a global multiplier for all your other units.

Composition Tip: Ensure your support units are leveled to the current cap. A support that dies to a stray AOE attack is a support that isn't providing the buffs necessary to secure the win. If you are struggling, prioritize the survivability of your buffers over the raw damage of your DPS for a few levels.

Resource Allocation and Account Progression

Clearing the Shibuya Incident EX stages is often a reflection of your account's long-term resource management. Spreading materials across too many units is the fastest way to hit a wall in this game.

• Focus Your Resources: Dedicate your upgrade materials to a "Main Four" core team. This team should be capable of handling various elemental requirements through sheer stat superiority.
• Memory Card Priority: Do not ignore your Memory Cards. High-level cards that provide percentage-based increases are often more impactful than a few extra character levels.
• Skill Enhancement: Prioritize the skill levels of your DPS unit’s ultimate and your buffer’s primary buffing ability. These two upgrades provide the highest return on investment for high-difficulty stages.

Looking Toward the Future: Anniversary Meta

With the anniversary event approaching, the Jujutsu Kaisen Phantom Parade meta is poised to shift significantly. Many players expect high-tier variants of characters like Toji Fushiguro to introduce power creep that makes current EX stages trivial.

How to Use Current Stages as a Benchmark: If you are currently clearing EX9 and EX10, your account is well-positioned for future content. If you are struggling, use this as a diagnostic tool. Does your team lack the raw damage (DPS check failure) or the survivability (Support failure)?

If you are failing due to a lack of damage, do not hoard your resources in anticipation of the anniversary banners. Spend them now to upgrade your core units so you can clear the current content and accumulate the rewards necessary to pull for upcoming, stronger characters. Investing in your current roster ensures you have the necessary currency to participate in the anniversary meta when it arrives.

Final Summary for Success

To overcome the EX9 and EX10 hurdles, remember:

1. Stop auto-battling: Manual control is mandatory for timing ultimates with buffs.
2. Stack Multipliers: A single turn where all buffs and debuffs overlap is worth more than three turns of uncoordinated attacks.
3. Check your Gear: If you hit a 20-million HP wall, it is almost always a sign that your Memory Cards or Skill levels are under-invested.

By prioritizing your Main DPS and ensuring your support units are properly leveled, you will be able to dismantle these bosses and prepare your account for the next wave of high-difficulty content in Jujutsu Kaisen Phantom Parade.
