Genshin Impact Thoma farming guide

Thoma is a well-known fixer around Inazuma and is the housekeeper for the Kamisato family. He's a half-Inazuman who originally lived in Monstadt, but was locked inside Inazuma after the Sakoku Decree was declared. Despite being a housekeeper, Thoma's undying loyalty to the Kamisato Clan often places him in unprecedented danger, to the point of almost being sliced by the Musou no Hitotachi. Here's everything you need to farm for Thoma.
