Desynth with Culinarian

[Raldo]

When desynthesis was added, several big fish could be desynthed into very lucrative swimwear and/or rare glamour ingredients. That was the original reason to level CUL desynth. They don't seem to have kept up with that though, since I can't recall anything SB fish that desynthed into anything particularly worthwhile, but the possibility is always there that they could do it again in the future.

Alternate reason for CUL desynth: It's cheap/easy to level up, and tons of fish have literally no other purpose in the game.

the sand that you often get is an ingredient for mortar, which is used in a lot of housing recipes - so don't just assume they're worthless and throw them out.

It's also easily available via lv15 mining points, so it's pretty worthless.
