Can you get the Iskaaran Fishing Gear items from NORMAL Magma Thresher Pools?

Can I get the fishing gear from normal magma thresher pools or ONLY the overheated ones? Trying to finish this out before WW but the droprates seem nonexistant. Wondering if I need to seek out overheated pools only, or…

They can drop from normal pools, but the droprate is so tiny, it isn’t worth it. I would strongly recommend sticking to overheated pools, only clearing normal ones that share a spawn with overheated ones.

edit: to add context, I completed all the fishing gear farming overheated pools and probably only got one drop from a normal pool.
