The Rotten Vale region in Monster Hunter World Iceborne has 10 Treasure Locations. This guide shows where to find all of them.
How Treasure Hunting Works
Each region has a total of 10 treasures. In order to start hunting treasures you will have to reach Unity Level 6 with the grimalkyne faction in the region you want to search for treasures (Bugtrappers for Ancient Forest, Protectors for Wildspire Waste, Troupers for Coral Highlands, Plunderers for Rotten Vale, Gajalaka for Elder’s Recess, Boaboa for Hoarfrost Reach).
To start leveling a faction you will first have to earn their trust by finishing their side quests, which also unlock a certain Palico Gadget from each of them. Use this guide for information on how to unlock all the Palico Gadgets: Palico Gadgets Guide.
Once you have a gadget unlocked in a region you can now use the help of a faction on a hunt. You can either just search for a grimalkyne on the map and it will join you on your hunt or you can use the new gadget “Tailraider Signal” you can unlock in Hoarfrost Reach which lets you call a tailraider like a taxi (highly recommended). Be careful though: you can only call a tailraider when you play solo, since it takes 1 of the 4 spots on your hunting party.
Once a faction reaches level 6 you will be able to perform pawswap with them in their lairs (marked on your map and also has a quick travel button). You can now trade them items for treasure tips. A grimalkyne will show their interest in your item by their movement. They can be non-interested and will turn their heads away, be curious or neutral about it, or go totally crazy for your item, jumping around, dancing around, basically begging you for it. That’s what you are looking for. Always give your items to the grimalkyne which wants it the most, or one of them since multiple can have the same reaction.
They enjoy stuff like potions, meat, traps, etc. Try giving them basically anything you have in your box, they might like it. They can drop the hints pretty fast sometimes and other times you will have to travel back and forward between regions a lot for a single hint, since you can only give them 3 items during a single visit. Only after you get the hint you can find the treasure. Some treasures have one or two hints before you can dig up the actual treasure.
This particular guide will cover the tresures locations in the Rotten Vale.
Tip: In the bottom left corner of the second screenshot of each treasure, you can view the exact map location. The area number (as seen on map) will be mentioned in the text below, just head to the area and check the minimap to align it with the screenshot. The 2nd screenshot also shows the exact spot to stand in for the treasure.
Number 1 can be found in the very north or area 13. Head through the bone-gates to reach it.
From camp 1 drop down and head right up the slope to the area where the stalagmites can drop down from the ceiling. There you can find the treasure in the southwest corner.
From camp 11 take the vines to climb up and follow the path. Right after the drop down you will find the treasure.
First hint will take you to the single tree in area 3. Not hard to find.
From this tree take the small tunnel south of it and drop into the pit with the cave paintings on a black wall. There will be the treasure.
In area 3, the same area as the single tree. Instead of going towards the tree take the slope down and on the corner you will find the second hint.
The treasure itself can be found next to the east wall of area 8.
Check the yellow grass in the north of area 9 to find the second hint for this treasure.
And the treasure itself will be in the acidic blue water in area 12 next to a rock.
Follow the hint to the south of area 2 where you can find the second hint.
The treasure can then be found in the east corner of are 4 at a red crystal.
The border of areas 12 and 14 hides the second hint.
It will take you to the bushes in area 10 next to some huge rib-bones.
And the treasure itself can be found in the very east of area 9 at the edge of the cliff there.
From area 8 head south into the lair of Great Girros and there in the corner you can find the next hint.
The second hint will take you to camp 1, where the final hint can be found.
Once again the treasure will be in the acidic blue water in area 12. Just above number 12 on your map.
Remember area 10 with the rib-bones? In the north corner of it will be our next hint.
Head into area 16 and check the bones in the southwest corner there. It is the place where Vaal Hazak takes his naps.
The final Rotten Vale treasure location can be found at the red wall in area 6.
