Treasure

Treasure chests and keys come in the same seven tiers as eggs, from Common up to Celestial, each with its tier’s colours and look. A chest opens only with a key of its own tier, so hold on to your keys. You hook chests, keys and gems while fishing, chests wash up on island beaches and drift across the open sea, and some are hidden for explorers to find. World chests are your own: every captain sees the same chest and can claim their own copy of it. Hooked chests and keys go up to Epic; Legendary, Mythic and Celestial treasure comes only from bosses. Keys are always earned, never bought.

Open your chests at the Treasure Dock on the harbor plaza: let go of a chest on the dock, or pick one from your treasure at its pedestal and turn the key in the lock yourself. Higher tiers hold richer rewards and put on a bigger show. Gems come in one kind per region, pearls, garnets, rubies and prisms, and you spend them on eggs at the Egg House and on rod tuning. Now and then you’ll also fish up a message bottle: read it for a few coins and a clue card with a rhyme that leads to a dig spot, where a buried chest waits for you.
