Thoma’s Talents

Swiftshatter Spear

They will also summon a Blazing Barrier, which can be stacked with Thoma's Blazing Blessing.

The character on the field can trigger the Fiery Collapse every 1 second. The effect of the Scorching Ooyoroi will disappear when Thoma falls, but he does not have to be on the field after activating the skill.

Team Compositions

Thoma is a Pyro support character, adding him to a team with a Pyro DPS like Hu Tao is optimal because he does not heal Hu Tao like Bennett and provides Pyro Resonance. As a shield support character, he is a great addition to vulnerable characters on the field like Eula, allowing them to stay on the field longer.

Hu Tao Team

Hu Tao and Thoma work great as a team because of their Pyro resonance.

Hu Tao will act as your main DPS in this team. Thoma is a great addition because he is a Pyro character that applies a shield but does not heal. Hu Tao can have an extra boost in damage while Thoma's shield can keep her in the field for longer. You can also add Xingqiu as a support for extra shield and Hydro element, or Aloy as a Cryo Sub-DPS. Lastly, an anemo character like Sucrose or Venti can keep your enemies clumped up together.

Childe Team

Thoma can apply Pyro to enemies off-field, allowing for a Vaporize reaction with Childe.

What makes Thoma a great partner to Childe is that he can constantly apply Pyro to enemies even if he is not on the field. Childe will act as your main DPS, causing a constant vaporized elemental reaction to enemies. You have to watch out for Childe's cooldowns, though. Adding Bennett to the team can give you Pyro Resonance and extra healing. Lastly, Kazuha can act as your Anemo support and sub-DPS.

Free to Play Team

Thoma is a shield support character that can apply Pyro to enemies while he is not on the field.

If you are looking for a free-to-play team for Thoma, you can use him as an Elemental Support. Aloy will act as your main DPS, applying Melt reaction to enemies. You can add Kaeya to the team to act as a sub-DPS and battery, giving you Cryo resonance. This will increase your CRIT Rate. Lastly, Barbara can act as your healer and Hydro support character. You can also swap out Aloy or Kaeya with Xiangling if you would like a reverse-melt party instead.


Characters like Hu Tao makes Thoma shine because he can protect your main DPS while providing Pyro resonance to the team.

Thoma is a 4-star Pyro character and the housekeeper of the Kamisato Clan. Thoma can give shields to his party members and absorb a lot of incoming damage from enemies. His kit revolves around his maximum health, which is why you should prioritize both Energy Recharge and HP% when farming for his artifacts. His Elemental Burst allows him to apply the Pyro element to enemies even when he is off the field.
