Pokémon Legends Arceus offers you a whole new style of play where you will have to capture several creatures to advance your research level. In order to meet Arceus, you will also need to fully complete your Hisui Pokédex. For this, you will need Pokémon whose appearance is quite rare such as Munchlax for example. Don't worry, unlike previous games, you won't have to wait for your 1% chance of spawning in a tree.
Where to find Munchlax?
Only two very specific locations will allow you to find Munchlax. Note that it is available at any time of the day and in any weather condition, but its spawn rate is very low. Thus, you will come across many more Crikzik in its place (at the Obsidian Plains) or even Snorlax (at the Panora-Neige Source). Stay vigilant and, as soon as you see him, save well before capturing him so as not to lose him if he flees. Prioritize the attack or capture from behind in order to surprise him and prevent him from moving on the first turn.
If you don't see a Munchlax at the indicated location, return to the village and then comeback to refresh the spawns.
Raise the Friendship to the maximum of Munchlax (by making him fight or by making him pick up berries in the trees for example) and raise him a level if you want to make him evolve into Snorlax.
