Stand Out Evolution
For SPTW, use Opal Roka on Star Platinum; for TWAU, use it on The World. Opal has a 10% swap chance and a separate 10% Stand-loss chance, so preserve the loadout you want before attempting a change.
Stand Out evolution routes
Stand Out evolution has two distinct tasks in this guide: swapping eligible Stand versions with Opal Roka and completing Billy’s quest for Hermit Purple. Choose the destination first. An arrow can help you obtain a base Stand, but it is not the item that directly grants SPTW or TWAU. Billy’s reward instead depends on a standless Jonathan Hamon setup and two quest objectives.
Scroll to see every column.
| Starting condition | Action | Destination |
|---|---|---|
| Star Platinum | Apply Opal Roka; swap is not guaranteed. | Star Platinum: The World (SPTW) |
| The World | Apply Opal Roka; swap is not guaranteed. | The World: Alternative Universe (TWAU) |
| Standless with Jonathan Hamon | Complete Billy’s DIO and plant objectives. | Hermit Purple |
The Opal item also lists SPTW and TWAU themselves as affected. These are paired version changes, so applying another Opal to a variant is not a guaranteed further upgrade.
Prepare before applying an Opal
First identify the exact Stand currently equipped. Star Platinum and Star Platinum: The World are different versions; so are The World and The World: Alternative Universe. A similar display name is not enough reason to spend the item without checking which version you already have.
Next read the kit you are choosing. SPTW has a one-bar short stop, a four-bar full stop, Time Jump and a zero-EX Campfire. TWAU has its own four-bar Time Stop with a held quick version. Compare those with Star Platinum and The World before deciding that a variant suits your play.
Then use D’Arby storage and chips to preserve a Stand you want to keep. A chip can return to storage or equip its Stand, but equipping it permanently loses the Stand currently in use. Preserving your current loadout and later replacing another one are separate decisions; inspect both sides of the exchange.
Finally apply Opal only to an eligible version after accepting the item’s outcome risk. The recorded outcomes are 10% to swap to the paired version, 10% to lose the Stand and otherwise no change. An unchanged result does not mean the next attempt is guaranteed.
Obtain a base rather than roll for a variant
The Stand Arrow guide covers the base pools, crafting costs and focused Part arrows. Its Part 3 focused route lists Star Platinum and The World at 5% each. Those values concern the named base results. They do not turn an arrow into a direct SPTW or TWAU roll.
DIO’s world-boss card also lists a possible The World Stand Chip. DIO spawns at night, and his drops scale with damage dealt; the card gives no numeric chance for the chip. If you use that route, distinguish the world-boss reward from Train and Highway Star raid chips. The raid guide covers those two farms and their separate shop destinations.
Complete Billy’s Hermit Purple route
For Hermit Purple, the quest giver is Billy. The quest requires no Stand and Jonathan Hamon. Your current Jonathan Hamon and standless setup determine whether you meet the quest conditions. Check the actual sub-ability before removing a Stand you value.
If you need to become standless, preserve the current Stand first and read Emerald Roka’s removal conditions. Emerald removes a Stand with a chance that scales by grade; the existing route requires Hamon or Vampire. For this quest, merely having Vampire does not meet the Jonathan Hamon requirement. Clear the Stand only when the Hamon setup is appropriate for Billy.
Accept the quest and complete its two recorded objectives: defeat DIO once and use Life-Giving Overdrive on plants 15 times. Plan DIO around his night spawn. For the plant task, Jonathan Hamon’s Life-Giving Overdrive targets a nearby growing crop, costs two EX bars and has a 25-second base cooldown. It speeds growth for ten seconds and stops when the plant is harvest-ready.
Return to the quest progression after both objectives are satisfied to obtain Hermit Purple. Its profile then explains tap-to-swing, hold-to-pull and the difference between ordinary and EX Grasp. The reward gives you a different movement and control kit. Read its move details next to learn the new vine inputs.
Choose the next useful task
If you lack the required base, gather arrows or compare the documented chip route. If you have the base but want to keep it, solve storage before using Opal. If your aim is Hermit Purple, prepare Jonathan Hamon and growing crops rather than spending arrows searching for the quest reward. Each route uses a different starting condition, so the next useful action depends on what you already possess.
