Thoma is easiest to build when you decide whether the team needs a Burgeon trigger, a Hyperburgeon shell, Overload support, or a pure shield. His best modern value comes from matching ER, EM, and HP to that exact job instead of forcing one generic support setup everywhere.
Quick answer: Build Thoma by team job. Hyperburgeon and Burgeon want enough ER plus EM to trigger seeds reliably, Overload teams value Pyro application and defensive comfort, and pure shield teams can lean HP/ER. Do not mix full HP and full EM priorities unless the team truly needs both.
Thoma's role, element, weapon type, and talent names give the guide its baseline; the build advice below turns that profile into practical choices for current accounts.
Thoma should be treated as Pyro shielder, Burgeon or Hyperburgeon trigger, and Overload support. That one decision controls the artifact set, main stats, weapon value, and whether the team needs a battery, healer, shield, or stronger off-field application.
| Build choice | Recommended setup | When to use it |
|---|---|---|
| Main role | Pyro shielder, Burgeon or Hyperburgeon trigger, and Overload support | Use this to decide field time and team order. |
| Artifact direction | 4pc Flower of Paradise Lost or Gilded Dreams for Burgeon or Hyperburgeon, 2pc HP + 2pc ER/HP for shield support, or 4pc Noblesse where Burst uptime is stable | Choose the set that supports the role before min-maxing substats. |
| Main stats | ER or EM sands, EM or HP goblet, EM/HP/CRIT Rate circlet depending on Hyperburgeon, Burgeon, shield, Overload, and Favonius needs | Fix energy, scaling stat, and survival before showcase CRIT. |
| Talent order | Burst > Skill > Normal Attack | Level what the rotation actually uses. |
| Icon | Recommendation | Use case |
|---|---|---|
![]() | Kitain Cross Spear 4-Star, Elemental Mastery | Use when its sub-stat or passive supports the rotation. |
![]() | Favonius Lance 4-Star, Energy Recharge | Use when its sub-stat or passive supports the rotation. |
![]() | Black Tassel 3-Star, HP Percentage | Use when its sub-stat or passive supports the rotation. |
![]() | Dragon's Bane 4-Star, Elemental Mastery | Use when its sub-stat or passive supports the rotation. |
![]() | Rightful Reward 4-Star, HP Percentage | Use when its sub-stat or passive supports the rotation. |
![]() | Prototype Starglitter 4-Star, Energy Recharge | Use when its sub-stat or passive supports the rotation. |
When choosing between weapons, test the second rotation rather than only the first burst window. If Thoma loses Burst uptime or the support passive misses the main damage window, a lower-rarity weapon with the right stat can be the better build.
| Icon | Recommendation | Use case |
|---|---|---|
![]() | Noblesse Oblige ★★★★, ATK | Use when the set bonus matches the role described above. |
![]() | Flower of Paradise Lost ★★★★, Elemental Mastery | Use when the set bonus matches the role described above. |
![]() | Gilded Dreams ★★★★, ATK | Use when the set bonus matches the role described above. |
For stats, start with ER or EM sands, EM or HP goblet, EM/HP/CRIT Rate circlet depending on Hyperburgeon, Burgeon, shield, Overload, and Favonius needs. If the recommended artifact table and your account situation disagree, prioritize the stat that keeps Thoma's real rotation functioning, then improve substats gradually.

Priority: Burst > Skill > Normal Attack

Normal Attack Performs up to four 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.

Priority: Burst > Skill > Normal Attack

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.

Priority: Burst > Skill > Normal Attack

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.
Rotation note: build shield stacks with Skill and Burst before the driver attacks, keep Hydro/Dendro order clean for Burgeon, and maintain enough ER for every rotation. The GIFs above are useful for checking timing, range, and animation commitment before you decide how much field time Thoma should take.

Example: Thoma / Xingqiu or Yelan / Dendro support / Kuki Shinobu or Electro trigger
Use this when Thoma can trigger Burgeon while an Electro slot adds Hyperbloom or Overload pressure without breaking the core aura plan.
Example: Thoma / Hydro applier / Dendro support / healer or driver
Use this when Thoma owns the seed trigger and can build enough ER and EM to keep Burgeon consistent.
Example: Thoma / Electro carry / Chevreuse / Pyro or Electro flex
Use this when Chevreuse-style Overload teams want Pyro application, defensive comfort, and a flexible Pyro slot.
Example: Thoma / Hu Tao or Pyro carry / Xingqiu or Yelan / Anemo or Hydro flex
Use this when the Pyro carry needs interruption resistance and Thoma's Pyro hits do not steal too many reactions.
Team examples are functional shells, not fixed account rules. Replace premium units with characters that perform the same job: application, battery, buff, resistance shred, healing, or shielding.
Thoma is worth building when you need a reliable Pyro defensive unit, Burgeon or Hyperburgeon trigger, or Overload support. He is stronger when the team clearly defines whether he is shielding, triggering reactions, or enabling a Pyro/Electro shell.
The safest Thoma build depends on the job: EM and ER for Burgeon or Hyperburgeon, HP and ER for shielding, and enough Pyro uptime for Overload support.
Use the weapon table as a starting point when it matches your stat needs, then compare them with flexible options such as Kitain Cross Spear, Favonius Lance, Black Tassel, Dragon's Bane for Burgeon, Rightful Reward, or Prototype Starglitter.
Use teams that match Thoma's job: Hyperburgeon, Burgeon driver shell, Overload support, or Vaporize shield.
Yes, but follow the priority. For most builds: Burst > Skill > Normal Attack.
Thoma is worth building when your account needs Burgeon, Hyperburgeon, Overload support, or a Pyro shield. He feels best when the team decides between EM reaction trigger and HP shield support before farming artifacts.
A strong Thoma build is a full account plan: kit facts, exact material costs, weapon and artifact choices, then a team that keeps the rotation repeatable. Start with the role, test the second rotation, and only then spend resin on refinements.
