Thoma is a four-star pyro character in Genshin Impact and a great companion to the already powerful Hu-Tao. If you are hoping to pull him though, then you are going to need to do some grinding to level him up all the way. Thoma, like most characters, is going to take quite a bit of mora, experience, and enemy drops to reach maximum level.
If you really enjoy his playstyle, then you may even want to crown him. The guide below goes over everything you need to know about leveling Thoma, ascending him, and ensuring that all of his talents are maxed out.

Treasure Hoarder Insignias can be gathered from Treasure Hoarders, so you likely already have quite a few in your inventory. If you still need insignias, then you can find Treasure Hunters roaming around ruins in all three regions. Fluorescent Fungus is a bit harder to get as it is found around Tsurumi Island.
Until you clear the fog on the island, you won't be able to gather much Fluorescent Fungus; for help with the quest, click here.
