What Mermaid Isle codes give you
Codes primarily reward Pearls and cosmetic items. Pearls are used in the in-game shop to purchase tails, accessories, makeup sets, and other customization options. Some codes unlock full tails directly, including higher-tier designs such as Exquisite or Uncommon variants.
Tails are a central part of progression and style, with categories ranging from Common to Mythic, plus special Radiant variations tied to certain sets. Codes that grant tails provide immediate access without needing to farm currency or complete quests.
New codes typically appear alongside updates, seasonal events, or milestone celebrations. Checking regularly ensures you don’t miss limited rewards that may not return once they expire.
