whats the chace of getting a rotted seed in reinforced crabcage

The chance is about 1 in 2,000 in Toxic Grove, and it’s reportedly guaranteed by pity after 2,000 catches. Some player reports also say Scavenger can improve it to around 1 in 666 , and a toxic boil can boost it further to about 1 in 333.

Quick scoop

• Base chance: 1/2000.

• With Scavenger: about 1/666.

• With toxic boil + Scavenger: about 1/333.

• Pity: guaranteed after 2,000 catches.

Practical note

If you’re specifically farming it from reinforced crab cages, the public sources I found don’t confirm a separate cage-only drop rate; the strongest consistent info points to fishing in Toxic Grove rather than cages.

TL;DR

Best estimate: 1/2000 normally, with pity at 2000 catches. Boosts from Scavenger and toxic boils seem to improve the odds substantially.
