How to Get Rotting
Only the Splitbranch Twig gives Rotting: 35% of the fish you catch with it. The rod costs 25,000 C$ in Everturn Forest.
Rotting multiplies a fish's sell value by 0.9x: a fish worth 1,000 C$ sells for 880 C$ with it. That is below 1x, so it makes a fish worth less than with no mutation at all.
