Stand evolution
Understand Opal Rokas, alternate forms, and the risk before you transform.

Pinnacle is a rarity label. Evolved and quest-acquired Stands use additional routes; owning a high-rarity Stand does not mean it has evolved.
The two reported Opal routes
Star Platinum can become Star Platinum: The World. The World can become The World: Alternative Universe. Both are reported to use an Opal Roka rather than a direct arrow roll.
Read the item tier first
The published base description gives a 10% transformation chance and a 10% Stand-loss chance, with no change otherwise. Roka tiers reportedly alter these risks; S-tier is described as having no loss chance. Full per-tier rates are not documented here. Read the actual item before using it.
Other Roka types
Emerald is associated with Stand removal, Sapphire with sub-ability removal, and Amethyst with resource bars. These have different purposes; do not substitute one based on color alone.
Quest routes and future variants
Hermit Purple is tied to a Jonathan Hamon quest while Standless. Jojosapiens has a quest route. Announced future variants should not be treated as obtainable until the game confirms them.
