Since I’m solidly in the Monster Hunter World endgame now, I figure I want to start documenting some stuff into guide-like format for interest/posterity. I do frequent /r/MonsterHunter/, so I get exposed to many of the commonly asked questions, which would frequently benefit from a guide with pictures!
So, to start off, here are the locations for the rare canteen ingredients!
You should be aware of the research point gathering spots on each map, the ones that give you a canteen ingredient from a rare gather? Well, I just found out the other day that there’s an even more rare gather, specifically there is a unique gathering node only when the locale has “Flourishing” or “Upsurge” for that type of node. For example, in Coral Highlands, an “Upsurge: Pearl Oysters” will spawn a unique Pearl Oyster node. Gathering at that node will give you an account item for a new canteen ingredient!
I will update this post as I get more screenshots! Warning that this technically spoils some areas and names if you haven’t unlocked them yet. If you just want a hint for where you find it, you can ignore my description and only use the screenshot, or maybe the minimap on the screenshot :)
