What is the most efficient way to farm Cavern Mushrooms?

[KurokaiSO]

I have every ingredient I need for the Pal Research Lab (Medicine Production) and I'm in need of 700 Cavern Mushrooms in total to complete it.

I personally think that the Expedition Station isn't worth the wait and the chances of gathering them. Any tips to speed up to process?

restart dungeons b4 boss fight.
Expedition Station is a added bonus except for slabs.

Afaik, expeditions and caverns themselves are the only way to get them.

sadly the expeditions are the fastest way to grind those mushroom.
ones you have done all the bosses on normal mod then the hardmod grizbolt fight you get access to a expedition that 100% of the time give about 10 mushrooms.

if you grind alphas, max condense and max out HP/ATK/DEf with souls and IV you can cut the timer by a lot.

i myself have a entire page fuel of jormuntide ignus for the Xenolord fight and all though they are far from finish and only 6-7 of them are alphas. just with them i have expedition time of 6 minutes. ones i'm done with them i bet i can get the 5 minutes limit.

if you like to grind at the same time go to underground bosses on the map to grab some.
example be: splatterina, lyleen noct. blazumut, ect...
