Do you find your home very empty in Pokémon Legends Arceus? It's normal ! When you start you'll have nothing but walls in there but there are two ways to "decorate" your home.
Collect the Pokeshi Doll
By completing the request number 18 in the village, you can learn the crafting recipe for the Pokéshi Doll. Anvin will then ask you to craft one for him to complete the mission.
Buy furniture from Merchant Ginko
On the right of HQ Galaxy, in Rusti-Cité, two Ginko merchants will have a trailer to sell you some items. The one on the right will offer you fixed merchandise that will evolve over your Grade while the one on the left will offer you a unique item from time to time. To have new stock, you have to go on a mission several times in a row.
Thus, he will sometimes sell you evolution objects but especially very special machines which are actually receptacle machines for Rotom. By buying them all, laundry basket machine, cutting machine or even rectangular machine, you will then obtain household appliances in your Logis.
The Crunchy Salt is a resource that you will need to complete the Even More New Wares request from Choy in Pokémon Legends Arceus. Here's where to find it in Hisui.
