Fishing and treasure recipe bonuses

Ordinary fishing#

At 80.0 base Fishing or above, a successfully delivered ordinary Fish has a 0.2% chance to award one randomly selected tier-one recipe. This is a bonus attached to the delivered catch, not a roll on every cast or on special fishing rewards.

The recipe must fit in your backpack. If it does not, that bonus recipe is discarded while the original fish catch is kept. Fishing, adventure and shared progression eligibility checks still apply.

Treasure-map chests#

A nontemporary treasure-map chest rolls once when it is created. Its chance is 3% + 2% per chest level, capped at level six for the formula. Existing chests are not given another roll simply by reopening them.

SOS salvage#

SOS salvage uses its own recipe roll after the normal chest contents are filled. It does not additionally run the treasure-map recipe constructor roll. Ancient SOS salvage explicitly uses level five for recipe discovery, regardless of the ordinary chest fill’s level cap.

Interpreting the odds#

Each successful bonus chooses uniformly among six recipes at that tier. The chance is for any recipe, not for a specific recipe or an unlearned recipe. Duplicate scrolls can occur and remain tradable if already known.
