Pick mutations by value first
The biggest multipliers matter most on rare or heavy fish because they multiply the final sale value. High-value mutations like Aether, Fury, Hades' Curse, Tryhard, and Plagued are worth tracking separately from common visual rolls because their routes are much more specific.
Appraising is only part of the system
Some mutations can be added or removed through the Appraiser, but many of the strongest rows are not appraisable. Rod passives, special baits, weather, pools, and event-style mechanics can matter more than repeatedly appraising the same fish.
High multipliers still make a major sale-value difference, but the routes vary a lot. Check whether the row is appraisable or locked behind a particular rod, enchantment, or fishing condition.
Low multipliers are often visual, utility, or route-specific mutations. Some are still worth knowing because they connect to appraising, NPC sales, or other mutation chains.
Mid-range mutations are useful value boosts and include several weather, rod, and pool routes. These are easier to compare once the top-value rows are out of the way.
These lower the sale value. They still matter because players may want to avoid them, understand a bad roll, or keep a special visual fish.
