Thoma — Build, Teams & Rating Genshin 6.7

Is Thoma worth building?

Thoma is an easy-to-get 4-star shielder (his shield is usable even at C0), great for anyone who wants a durable layer of armor without spending a DPS slot. His shield scales with max HP, so stack HP% everywhere, and crucially build enough Energy Recharge to burst every rotation. He also shines as a Burgeon trigger with the Flower of Paradise Lost set. Don't expect damage; Thoma's value is safety. Prioritize Favonius Lance and full HP%.

Thoma's talents

Swiftshatter Spear

Normal Attack
Performs up to 4 consecutive spear strikes.

Charged Attack
Consumes a certain amount of Stamina to lunge forward, dealing damage to opponents along the way.

Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.

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.

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."

Imbricated Armor

When your current active character obtains or refreshes a Blazing Barrier, this character's Shield Strength will increase by 5% for 6s.
This effect can be triggered once every 0.3s seconds. Max 5 stacks.

Flaming Assault

DMG dealt by Crimson Ooyoroi's Fiery Collapse is increased by 2.2% of Thoma's Max HP.

Snap and Swing

When you fish successfully in Inazuma, Thoma's help grants a 20% chance of scoring a double catch.

Combat Rotation

Cast Elemental Skill (E) "Blazing Blessing" — deals AoE Pyro DMG, applies Pyro to Thoma himself, and creates a Blazing Barrier shield (CD 15s).
Right after E, swap to your driver character immediately — the Pyro just applied to Thoma lets their next hit trigger a reaction (Vaporize, Overloaded, etc.).
Once you've charged 80 Energy, use Elemental Burst (Q) "Crimson Ooyoroi" — deals AoE Pyro DMG and grants Scorching Ooyoroi for 15 seconds.
While Scorching Ooyoroi is active, switch to your main DPS and keep auto-attacking — each Normal Attack triggers Fiery Collapse (AoE Pyro DMG + a fresh shield), capped at once per second.
Stick to Normal Attacks (avoid Charged Attacks) on your main DPS so the shield keeps refreshing and you get full value out of Scorching Ooyoroi's duration.
Recast E on its 15-second cooldown between Bursts to refresh the shield and reapply Pyro to Thoma.
Prioritize Energy Recharge (artifacts/support characters) to reach the 80-cost Burst quickly, then repeat: E → swap to DPS → Q → Normal Attacks.
Thoma doesn't need to stay on field after E/Q — he functions as a background shielder/support, letting your main DPS hold field time while the shield and buff carry over.
