Stand Out Stand Evolution: Opal Roka, SPTW and TWAU

Evolution here is an item transformation, not levelling. You eat a special fruit, the Opal Roka, while holding a base Stand, and the game may swap it for a related version. The official Trello keeps a list called Evolution/Quest/AU Stands, and it holds two true evolutions plus Hermit Purple.

Both evolved Stands sit outside the arrow pool, so no arrow, chip or reroll can give them to you. See the full Stands list for the base Stands.

The Opal Roka card lists four Stands it affects: The World, TWAU, Star Platinum and SPTW. Eating one on an already evolved Stand also has a 10% chance to swap to the other version, so you can in theory go back, but the same 10% wipe risk applies.

The October 7 patch notes say more Stands will get variants later, such as King Crimson to a King Crimson AU or Star Platinum to a Part 4 version. Neither exists yet, so treat them as planned, not released.

Per Opal Roka the official card says 10% to swap to the other version, 10% to lose your Stand, and otherwise nothing changes (80%).

The October 7 changelog adds that Roka tier scales both the chance to work and the chance to wipe, and that an S tier Opal Roka has a 0% chance to wipe. The 10% and 10% figures are what the card prints today. We list per-tier numbers as TBC because the developers have not published them.

Because a wipe loses the Stand for good, only eat one on a Stand you can re-roll or re-earn. Rokas that remove a Stand, remove a sub-ability or transform a Stand cannot go into splash mode containers.

Opal Roka is a Roka mutation. The October 7 patch says mutated Rokas have a 3% chance per fruit when you grow them, so you farm it in gardening, ideally in a gang base where Rokas grow at 3x speed (October 29 update). The Trello does not give a store price or a fixed drop, so a guaranteed source is TBC.

Other mutations from the same patch: Emerald Roka removes your Stand, Sapphire Roka has a 50% chance to remove your sub-ability, and Amethyst Roka restores EX and other bars instead of HP.

Star Platinum: The World keeps Star Platinum's strength and speed and gets a new moveset. Cooldowns are from the Trello card.

• Ora Blitz (19s): a barrage that carries enemies and deflects projectiles.
• Bearing Toss (9s): steel bearing, reaches 250 studs, headshots knock down.
• I'm Wide Open (24s): counter that puts you behind the attacker.
• Time Jump: instant jump up to 64 studs at base Ability.
• Bane of Rats: use H to catch frozen knives, nails or bullets in Time Stop and throw them back.
• EX moves: Campfire (20s, no EX cost), Tandem Rushdown (2 bars) and Panic Time Stop, 20s cooldown for the short stop and 60s for the full one.

See controls for the key layout.

The World: Alternative Universe plays close to The World. Barrage stays at 23s and Hole Puncher at 30s. It replaces Knife Throw and Head Slam with Deadly Shot (7s), a high-caliber bullet with a tap-again follow-up.

Its Time Stop has a 22s cooldown versus 36s on The World. The Pilot variant of Barrage is marked currently glitched on the Trello, so expect bugs there.

Pinnacle is a rarity tier, not an evolution result. Star Platinum, The World and King Crimson are Pinnacle from arrows (5% each on their Part 3 and Part 5 arrows), and the Jotaro and DIO bosses can drop chips. Hermit Purple is filed under Evolution/Quest/AU Stands on the Trello, but you unlock it through Bill's Request with Hamon and no Stand.
