Monster Hunter World: Rotten Vale Grimalkyne Quest Guide

In this guide, you learn where to find the Plunderer Grimalkyne tribe in the Rotten Vale area of Monster Hunter: World. The Rotten Vale Grimalkyne tribe is the “last” of the Palico equipment gadgets and does not require a quest to obtain the reward.

However, you must have already completed the Ancient Forest Grimalkyne, Wildspire Waste Grimalkyne, and Coral Highlands quests in order to obtain the Plunderblade from this tribe.

Upon finding the Palico and feeding it you obtain the Plunderblade Palico gadget which you can then equip to your Palico. The Plunderer Grimalkynes can also accompany you on expeditions and solo quests as well.

Monster Hunter: World Rotten Vale Grimalkyne Tribe

Rotten Vale is one of the areas you explore in Monster Hunter: World. And the Plunderer Palico tribe is the local Grimalkyne tribe that you can encounter.

Rotten Vale – Plunderers

To start the quest to find the Plunderblade, you have to unlock the lowest level of Rotten Vale. And, you must enter the area on a solo Expedition.

A Plunderer roams around in Area 13 but it only appears after the Odogaron has dragged over the Legian corpse from Area 9.

Once you spot it, it runs away and as usual, you chase it with scout flies to the dead end in Area 15. It retreats to their inaccessible hideout.

You must then place Raw Meat near the entrance when told to by your Palico. Go back as far as possible while still being in few of the Raw Meat.

After a bit, multiple Plunderers will come to eat the meat. After the usual cutscene happens and they join and reward you with the Plunderblade. (You do not have to wait for a Lynian Researcher to be present in the area.)


So, where to find the Rotten Vale Grimalkyne Tribe? To find the Palico Tribe, start an expedition and head to the Rotten Vale. However, choose to start at the central camp (if already set up). From here, it is simple.
