Thoma is a 4-star Pyro polearm user from Inazuma, serving as the housekeeper of the Kamisato Clan. While known for his polite demeanor and loyalty, in combat Thoma offers strong Pyro application, shield support, and utility in Burgeon and Overloaded teams.

The best Thoma build focuses on HP%, Energy Recharge, and Elemental Mastery depending on whether you build him as a shielder or a reaction enabler.

Thoma’s shield scales with HP, and his Elemental Burst deals continuous Pyro damage while providing additional shield refreshes. This makes him excellent for off-field Pyro application, particularly in Burgeon teams with Dendro cores.

How to Play Thoma Effectively

Thoma is most effective as an off-field Pyro support or shield generator. His Elemental Skill, Blazing Blessing, creates a Pyro shield that scales with Max HP. His Elemental Burst, Crimson Ooyoroi, provides periodic Pyro damage from off-field and refreshes his shield.

The best Thoma build focuses on either maximizing HP for shield uptime or Elemental Mastery for Burgeon triggers. For Burgeon comps, focus on EM and reaction chains. For defensive builds, stack HP% and use ER to ensure consistent Burst uptime.

Is Thoma Worth Building?

Yes — Thoma is a versatile 4-star support with reliable shielding and unique synergy in Dendro-Pyro comps. He’s easy to build and brings utility even at low constellation levels.
