I took my tracker with my fisher and can't track deep sea serpents, as far as im aware these are meant to be trackable O_O
*thinks big fish should be caught individually as before* I'm fine either way but liked how one could catch a big at 65 skill, not as serp bycatch at 80 skill.
Big fish could begin to be caught at 90 skill, the same level as treasure maps. This was moved to 95 to account for some Anti AFK gathering chances. In a recent patch, in order to elevate the afk system to only checking grandmaster fishers, big fish were moved into the belly's of sea serpents. The rate at which they can be fished up should be changed slightly in patch 38, however they will continue to be available to be fished up at 95 skill.
