What element is Thoma?

Thoma is a 4-star Pyro character from Inazuma who uses a polearm, released in version 2.2.

What stat does Thoma scale on?

Thoma's abilities multiply HP. That is read from the scaling rows on the Elemental Skill and Burst, not from the ability description, so it reflects what the game actually multiplies rather than what the text mentions.

What is the best weapon for Thoma?

Crimson Moon's Semblance is the closest fit on the data: it is a 5-star polearm with CRIT Rate as its ascension stat, and its passive acts on HP. Rightful Reward is the best 4-star alternative.

How much does it cost to level Thoma's talents?

Taking one talent from level 1 to 10 costs 1,652,500 Mora and 38× Philosophies of Transience among other materials. The Materials tab lists every item per level.

What does Thoma C1 do?

A Comrade's Duty: When a character protected by Thoma's own Blazing Barrier (Thoma excluded) is attacked, Thoma's own Blazing Blessing CD is decreased by 3s, while his own Crimson Ooyoroi's CD is decreased by 3s. This effect can be triggered once every 20s.

Thoma build summary

Updated August 28, 2026

Crimson Moon's Semblance is the closest fit on the game's own numbers: Thoma's kit multiplies HP, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Staff of Homa, Rightful Reward and Vortex Vanquisher come next. No playtested ranking has been imported for Thoma, so this is arithmetic over the kit data rather than a damage measurement.

Run Crimson Witch of Flames on Thoma, with Vourukasha's Glow and Tenacity of the Millelith behind it. Main stats are HP% sands, HP% goblet, HP% circlet. Roll substats in the order Energy Recharge > HP% > CRIT Rate > CRIT DMG.

Talent priority is Elemental Burst > Elemental Skill > Normal Attack. The Elemental Burst costs 80 energy, which is what an Energy Recharge target has to clear.

Skill

Blazing Blessing

Thoma vaults forward with his polearm and delivers a flame-filled flying kick that deals AoE Pyro DMG, while also summoning a defensive Blazing Barrier. At the moment of casting, Thoma's Elemental Skill applies Pyro to himself. The DMG Absorption of the Blazing Barrier scales off Thoma's Max HP. The Blazing Barrier has the following traits: · Absorbs Pyro DMG 250% more effectively. · When a new Blazing Barrier is obtained, the remaining DMG Absorption of an existing Blazing Barrier will stack and its duration will be refreshed.

The maximum DMG Absorption of the Blazing Barrier will not exceed a certain percentage of Thoma's Max HP.

As a guest from afar, only the most burning passion would allow one to master the pure and precise spear arts of Inazuma. Thoma's mastery, indeed, is not limited to being the "swiftest-studying student" or "a master of the spear," but he has imbued his will to protect others and fend off foes into his art as well.

Burst

Crimson Ooyoroi

Thoma spins his polearm, slicing at his foes with roaring flames that deal AoE Pyro DMG and weave themselves into a Scorching Ooyoroi.

Scorching Ooyoroi While Scorching Ooyoroi is in effect, the active character's Normal Attacks will trigger Fiery Collapse, dealing AoE Pyro DMG and summoning a Blazing Barrier. Fiery Collapse can be triggered once every 1s.

Except for the amount of DMG they can absorb, the Blazing Barriers created in this way are identical to those created by Thoma's Elemental Skill, Blazing Blessing: · Absorbs Pyro DMG 250% more effectively. · When a new Blazing Barrier is obtained, the remaining DMG Absorption of an existing Blazing Barrier will stack and its duration will be refreshed.

The maximum DMG Absorption of the Blazing Barrier will not exceed a certain percentage of Thoma's Max HP.

If Thoma falls, the effects of Scorching Ooyoroi will be cleared.

"I will not forget my initial promise. Let this burning flame protect those I cherish, and may it never be extinguished."
