Leveling in Roblox Is Unbreakable requires clearing story chapters, meeting specific level thresholds to accept key boss quests, and farming replayable encounters or Trials. Progress starts in Part 1 (Phantom Blood), shifts to Part 5 (Vento Aureo) at level 20, and opens Part 7 (Steel Ball Run) at level 70.

Part 1: Phantom Blood Leveling Walkthrough
New characters begin outside the Joestar Mansion. The early game focuses on collecting cash, learning your first specialty, and breaking through the initial level gates.
Mansion to London (Levels 1 to 5)
- Speak with Jonathan Joestar on the right side of the Joestar Mansion grounds.
- Spar against Dio in the boxing match, then return to Jonathan inside the mansion.
- Jonathan instructs you to travel to London to investigate the poison given to his father. Use The Coachman cab outside the mansion gates for fast travel.
- Search London for chests or dropped items on the ground. Sell collected loot to the Black Market Dealer to accumulate cash.
- Take the street quest from the Police Officer at level 5 to defeat five criminals for early experience and money.
- Locate Speedwagon in the underpass. He requires a payment of $1,500 to share details regarding the poison.
Hamon Training and Windknight's Lot (Levels 5 to 14)
After paying Speedwagon, return to the Joestar Mansion to consult Jonathan, then locate Will Zeppeli just outside the property.
Zeppeli teaches the Hamon specialty for $2,000. If short on funds, farm London chests or street enemies. Hamon adds a dedicated energy gauge and unlocks foundational skills such as Zoom Punch (unlocked at level 9 in the skill tree) and Sunlight Yellow Overdrive.
Once equipped with Hamon:
- Speak with The Coachman to travel to Windknight's Lot.
- Accept Straizo's quest to eliminate 10 zombies.
- Advance to the graveyard on the left side of Windknight's Lot and speak to Zeppeli at level 10 to receive the Bruford boss quest. Bruford respawns roughly every three to five minutes. Defeating him offers a 5% chance to drop the Pluck Sword as a global pickup.
- Farm surrounding zombies until reaching level 15. The subsequent quest will not open beforehand.
Clearing Part 1 (Levels 15 to 20)
Travel up the hill to Dio's Castle and speak with Jonathan. At level 15, Jonathan issues the quest to slay Dio inside the castle tower.
Block Dio's eye laser attacks to cut incoming damage in half, and channel Sunlight Yellow Overdrive during his vampire barrage. Once Dio falls, story mode registers as complete, but your character will likely sit around level 18 or 19. Open the quest log, navigate to "Dio the Invader", and select Replay. Slaying Dio a second time, or farming zombies in Windknight's Lot, brings your character to level 20.
Part 2: Vento Aureo Progression (Levels 20 to 70)
Exit to the main menu at level 20 and load into the Vento Aureo map set in Naples. Level 20 also unlocks the ability to redeem codes and interact with Daniel J. D'arby's gambling table.
Naples Story Objectives
Press M to reference the map, or use local cabs for transit across Naples ($1,000 to $3,000 per trip):
- Speak to Koichi near the start. Confront Giorno to retrieve Koichi's stolen luggage. Returning the bag awards an Arrow. Stand Arrow survival rates scale directly with character level, meaning low-level attempts carry a chance of death.
- Locate Giorno again to receive the quest targeting Leaky-eye Luca. Defeating Luca awards a shovel weapon.
- Travel to the train station to battle Bruno Bucciarati.
- Visit Polpo in prison to receive the lighter challenge, requiring you to protect the flame for three minutes.
- Regroup with the team at the cafe, answer the math questions, and speak with Mista and Abbachio.
- Meet Mr. X near the middle school to complete designated bounty assignments and city tasks.
- Challenge Risotto Nero and push through remaining mafia battles leading toward Diavolo.
Fast Leveling Routes: Trials and Quests
Reaching higher milestones like level 70 for Steel Ball Run and level 100 for endgame builds requires structured grinding beyond one-time story completions.
Trials Farming
Trials are accessible through Funny Valentine or the main menu screen. These boss battles award substantial sums of experience, cash, and shared item drops across squads. Farming Trials in a group speeds up kill times without penalizing individual loot drops. High-tier trial bosses include:
- Diavolo
- DIO (required to evolve Star Platinum into Star Platinum: The World)
- Jotaro Part 4
Quest Replays and Space-Time Rifts
If boss Trials feel overtuned for your current build, farm repeatable open-world encounters:
- Quest Replays: Replaying boss quests such as Dio or Risotto from your quest log provides fixed experience payouts on completion.
- Space-Time Rifts: Dimensional tears scattered across the map spawn enemies that yield heavy experience upon defeat.
- Double XP Events: Playing during active Double XP weekends accelerates progression through intermediate level locks.
Skill Tree and Stat Allocation
Every level-up grants one skill point. The character tree contains 77 total points distributed across four core attributes:
| Attribute | Primary Effects | Build Considerations |
|---|---|---|
| Vitality | Raises maximum health pool and speeds up passive HP regeneration. | Crucial for early survivability against boss barrages. |
| Strength | Increases base attack damage and raises maximum equipment weight limit. | Primary damage stat; allows equipping heavy armor sets without speed penalties. |
| Agility | Increases base movement speed and extends dash distance. | Counters heavy armor weight penalties; enables effective dodge recoveries. |
| Defence | Increases Block HP (the blue guard bar) and block duration. | Prevents block breaking and avoids stun states during prolonged combos. |
Exceeding your character's equipment weight limit disables sprinting entirely, while reaching half capacity inflicts a slight movement penalty. Invest points into Strength to carry protective armor without sacrificing mobility. Stand-specific skill trees function independently from the base character tree and reset whenever you swap your Stand.
Frequently Asked Questions

How does the Stand Arrow success rate work?

Defeat Dio at his castle, open your quest menu, and replay the "Dio the Invader" quest. Alternatively, farm zombie mobs in Windknight's Lot until the level 20 milestone is reached.

Locate the Whitesnake NPC in the game world to reset an existing Stand or specialty skill tree.
