Roblox Is Unbreakable awards Tusk Act 1 when you merge your character with the Left Arm of the Saint's Corpse. Evolving Tusk through Acts 2, 3, and 4 requires learning the Spin specialty from Gyro Zeppeli, merging with a Ribcage, and riding a horse at 70 km/h during an active Steel Ball Run match.
How to Get Tusk Act 1
To obtain Tusk Act 1, you must acquire a Left Arm of the Saint's Corpse and use it from your inventory to merge with your character.
Each character level adds a 1% chance of a successful merge. Reaching level 100 provides a 100% guarantee that the merge succeeds, eliminating the risk of character death upon failure.
The Left Arm can be obtained through five primary methods:
- Steel Ball Run (SBR): Collect corpse parts from ground spawns marked by stars or loot them from eliminated players, then finish the race alive.
- Dimensional Rifts: Defeat the boss Funny Valentine inside rifts for a chance at a corpse part drop.
- Homeless Man / Beggar NPC: Pay $5,000 cash for a random item drop that has a low chance to yield a corpse part.
- Daniel J. D'arby: Spend tokens to roll cards for items, including corpse parts.
- Community Trading: Exchange existing parts or items with other players in trade hubs.
Merging with the Left Arm grants the Tusk Act 1 Stand alongside a passive bonus of 5% M1 damage.
| Tusk Form | Core Evolution Requirement | Key Location or NPC |
|---|---|---|
| Act 1 | Merge with Saint's Corpse Left Arm | Inventory (Anywhere) |
| Act 2 | Obtain Spin specialty, then talk to Gyro Zeppeli | Rocky Village (SBR Stage 2/3) |
| Act 3 | Merge with Saint's Corpse Ribcage and choose to shoot | Inventory (Anywhere) |
| Act 4 | Reach 70 km/h (8 speed upgrades) while riding horse | Active Steel Ball Run Match |
How to Evolve to Tusk Act 2
Upgrading from Act 1 to Act 2 requires unlocking the Spin specialty and speaking directly to Gyro Zeppeli during a Steel Ball Run match.
- Obtain a Steel Ball, which can be crafted, rolled via Daniel J. D'arby, or found in chests.
- Enter a Steel Ball Run race and ride to Rocky Village, located along the second stage route.
- Locate Gyro Zeppeli in Rocky Village.
- Interact with Gyro with a Steel Ball and $5,000 cash in your inventory to acquire the Spin specialty.
- Talk to Gyro a second time while equipped with Tusk Act 1 and the Spin specialty. He will give the dialogue prompt regarding Lesson 4 and the Golden Ratio, transforming your Stand into Tusk Act 2.
How to Evolve to Tusk Act 3
Transitioning to Tusk Act 3 requires a Saint's Corpse Ribcage. Similar to the Left Arm, your character level dictates your success rate per attempt, scaling at 1% per level up to 100% at level 100.
- Place the Saint's Corpse Ribcage in your inventory.
- Use the item to merge the Ribcage into your character.
- An apparition of the Saint appears, stating: "If your heart is wavering... Do not shoot. You will grow... Once more shall the gates leading to a new path open for you."
- Select the prompt to shoot yourself. This triggers the evolution into Tusk Act 3 and unlocks the Wormhole Nail Shot ability.
How to Evolve to Tusk Act 4
Tusk Act 4 requires reaching maximum cavalry rotation speed on a horse during an active Steel Ball Run match. You cannot perform this evolution in the pre-game lobby.
- Visit a Horse Trainer at the beach or designated settlements before or during SBR.
- Invest cash into horse stats until you reach 8 upgrades in top speed.
- Enter an active Steel Ball Run match.
- Mount your horse and accelerate until your speedometer hits 70 km/h (or 70 mph depending on HUD display).
- Trigger the evolution while riding at top speed to unlock Tusk Act 4.
Completing all horse upgrades requires $2,380,000 in total game funds. You can accumulate cash by completing bounties on SBR boards ($50,000 per target), finishing in the top five of an SBR race (up to $100,000 for 1st place), or defeating Diavolo to sell dropped Requiem Arrows.

Frequently Asked Questions
Can I evolve Tusk Act 4 in a private server or the lobby?
No. The evolution check requires your mount to maintain 70 km/h while an SBR match is actively running on the race course, not in the starting zone.
What happens if I fail to merge with a corpse part?
Failing a corpse part merge instantly kills your character and consumes the item. Raising your character level to 100 provides a 100% success rate.
Do I lose my corpse part if I die during Steel Ball Run?
Yes. If another player eliminates you while you hold a loose corpse part in Steel Ball Run, the part drops and can be claimed by other racers. Successfully merged parts remain bound to your character.
Can I switch back to earlier Tusk Acts after evolving?
The game allows switching between previously unlocked acts once they have been earned on your account profile.
