Thoma is a 4-star Pyro Polearm user in Genshin Impact, excelling as a support character who provides strong, stackable shields via his Elemental Skill 'Blazing Blessing' and Burst 'Crimson Ooyoroi'. Lore-wise, he serves as the affable and reliable housekeeper for the Kamisato Clan in Inazuma, known as a well-regarded 'fixer' who handles various tasks. His Burst triggers coordinated Pyro attacks with the active character's Normal Attacks, refreshing the Blazing Barrier and enhancing team survivability, especially in Burgeon teams.
