Monster Hunter: World has a couple of crossover events, but the most ambitious puts us in the shoes of Geralt of Rivia as he hunts down the monster that transported him and a Nekker to the forest. This turns out to be the Leshen who has taken up residence in the Ancient Forest and disturbed the natural order. You’ll therefore need to put it down.
Those new to hunting monsters, or if you just need to find a particular monster guide to get up to Hunter Rank 16 – needed to start this quest – should head over to our [cms-block] hub for a plethora of guides.
