Why Jotaro's Quest Matters
The Jotaro quest is a major gate on the path to Made in Heaven, not just another NPC errand. It connects the Saint's Corpse Parts, Heaven Ascension DIO, DIO's Bone, and the difficult Part 6 Jotaro battle into one progression chain.
In-game, Jotaro may appear under the name Joe or Joe Kujoe. The names vary by encounter, but the important distinction is between the mountain quest NPC, the train-station boss, and the Part 6 boss near Diavolo's Castle.
| Encounter | Location | Role in progression |
|---|---|---|
| Jotaro quest NPC | The Tallest Peak | Sends players to Heaven Ascension DIO after they have Corpse Parts |
| Jotaro boss | Naples Train Station | Optional boss unless taken through DIO's related quest |
| Jotaro Part 6 boss | Water beside Diavolo's Castle | Drops the Disc needed for Made in Heaven progress |
The mountain NPC is the version relevant to the first part of the quest. Speak with him, accept his request, and return only after you have gathered the needed Corpse Parts. He does not consume those parts when you show them to him, so keep them safely in your inventory.
Starting the Mountain Quest
For the your bizarre adventure jotaro quest, begin by finding Jotaro on the highest peak near the train-station side of the map. His dialogue explains that he needs the Saint's Corpse Parts to reach DIO's current realm.
You must carry all four Saint's Corpse Parts to advance. Redeemed Corpse Parts also count for this requirement. If you claim to have the parts without actually carrying the full set, the conversation will not move you forward.
| Requirement | What to know |
|---|---|
| Saint's Corpse Parts | Bring the complete set of four parts |
| Redeemed Corpse Parts | Valid alternatives for entering the Heaven encounter |
| Readiness | Accepting the final prompt teleports you immediately |
| Quest reward | The NPC quest provides $3,000 and 4,000 experience |
Before confirming that you are ready, finish your setup. The teleport is automatic, so this is a poor time to discover that your skill tree, fighting style, healing items, or Stand are not prepared.
A practical preparation checklist includes:
- Carry all required Corpse Parts before returning to the peak.
- Set your preferred Stand and skill tree before talking to Jotaro.
- Bring a fighting style you understand rather than testing a new build during the boss fight.
- Leave inventory room for quest items, especially DIO's Bone.
- Plan for repeated attempts if item drops do not happen immediately.
The quest NPC does not take the Corpse Parts away. That makes the interaction less punishing, but it does not make Heaven Ascension DIO easy. Treat the teleport as the start of a boss run rather than a simple hand-in.
Defeating Heaven Ascension DIO
After presenting the Corpse Parts, Jotaro sends you to the Heaven encounter to fight Heaven Ascension DIO. The immediate objective is DIO's Bone, which is one of the two key items needed later for Made in Heaven progression.
The fight rewards careful timing more than blind aggression. Build around reliable damage, mobility, and an answer to dangerous time-based attacks. A durable setup with ranged pressure or safe positioning can be more consistent than a fragile high-damage build.
| Goal | Recommended approach |
|---|---|
| Survive major attacks | Keep movement options available and avoid committing during dangerous openings |
| Deal steady damage | Use safe combos, ranged tools, or attacks that can punish recovery windows |
| Avoid repeated failures | Learn the boss pattern before spending long periods farming preparation resources |
| Collect DIO's Bone | Expect the possibility of multiple clears if it does not drop immediately |
The most useful habit is recognizing when to disengage. If the boss begins a sequence that your build cannot safely contest, create distance instead of forcing a barrage trade. A failed greedy combo can cost more health than a patient approach.
Once DIO's Bone is acquired, return to Pucci's quest progression. The next major requirement is defeating Jotaro Part 6 for his Disc. Keep C-Moon equipped when the questline requires it; changing to another Stand at the wrong time can prevent you from continuing until you switch back.
Beating Jotaro Part 6 for the Disc
Jotaro Part 6 stands in shallow water on the right side of Diavolo's Castle, near the prison area. This version has 600 health and uses Star Platinum: The World. He is among the hardest bosses in the game because he attacks aggressively, reacts quickly, and becomes especially dangerous as his health falls.
| Health phase | Likely threat | Best response |
|---|---|---|
| Opening | Combat Precision, M1 attacks, Ora Kicks | Damage him early, then be ready to block or parry |
| General combat | Platinum Slam, barrage, barrage finisher | Watch for the slam and avoid getting trapped in a full combo |
| Below half health | Time Skip into Ora Beatdown | Hold block and prepare to jump if needed for the parry |
| Around 35% health | Frequent Time Stop | Keep distance, use Time Stop resistance if available, and punish safely afterward |
His opening behavior gives you a short chance to establish momentum. If you stop pressuring him, he can enter Combat Precision and begin a punishing sequence. That does not mean you should attack carelessly; use quick, confirmed damage and reset when a move goes on cooldown.
Blocking is important, but do not hold it forever. Jotaro can recognize a sustained block and use a block-breaking option. Instead, block individual threats, look for parries, and move away after a successful defense.
His Time Skip and Ora Beatdown are key turning points. When he Time Skips behind you, holding block can allow a parry, though jumping preemptively helps against the lingering hitbox of his aerial variation. Below roughly 35% health, Time Stop becomes a recurring danger, so preserve defensive resources for the final phase.
Players with Time Stop resistance or canceling abilities have a meaningful advantage. Gold Experience Requiem can use Return to Zero to interrupt his Stand activity, while beatdown-capable Stands may blunt a Time Stop if timed just as it begins. These options help, but pattern recognition remains more important than any single build.
The boss respawns on a several-minute timer, and the Disc is not guaranteed. If the Disc does not drop, repeat the fight with the same disciplined approach. Avoid changing your entire build after one unlucky attempt unless you identified a specific weakness, such as lacking mobility or a safe answer to Time Stop.
