Genshin Impact Thoma Build Guide: Team & Materials for Patch 2.2 (November 2021)

Housekeeper by day, dangerous Polearm wielder by night: meet Thoma, the Pyro Zhongli.

He saved you from the Raiden Shogun and he’ll save you many more times. Thoma, the new 4-Star Genshin Impact character, could very well become your new favorite shield Support. The Kamisato family knew what they were doing when they hired this guy as their Housekeeper.

Thoma is featured on the second Wish Banner during Genshin Impact 2.2 (alongside Hu Tao). His abilities have already been discussed on the official Genshin Impact channels, but we relied on Honey Hunter World for some of the missing information. A big thanks to them! 

Let’s have a look at our best Thoma builds!

Thoma’s Abilities

If you thought Thoma was helpful in the story, you haven’t seen him in battle yet. Inazuma’s favorite fixer turns out to be an expert shield provider. His Elemental Skill is a pretty straightforward shield ability that’s especially effective against Pyro and scales with his max HP. Use this ability as often as possible.

His Elemental Burst also provides allies with shields, albeit slightly less effective ones. Keep in mind that additional Blazing Barriers will increase the overall shield strength. Don’t mistake Thoma’s Burst as a Support-only skill though; it will be pretty damaging once you unlock his Flaming Assault Passive.

Thanks to the extra Pyro absorption, Thoma is great against Pyro enemies. However, while he’s the perfect Support to take down Inazuma’s fiery Hypostasis, neither him nor any of your Pyro DPS characters will be able to deal damage. Against Pyro, the Kamisato Retainer should be relied upon for his Support only.

Swiftshatter Spear (Normal Attack)

  • Normal Attacks: Performs four swift strikes with the Polearm.
  • Charged Attack: Thoma consumes Stamina and dashes forward, dealing damage to all enemies in his path.
  • Plunging Attack: Deals AOE damage on impact.

Blazing Blessing (Elemental Skill)

  • Thoma performs a kick that deals AOE Pyro damage. He also summons a defensive Blazing Barrier. 
  • Blazing Barrier’s damage absorption scales with max HP. It has the following traits:
    • The Blazing Barrier can stack, so unleashing a second one won’t reset the remaining defense from the first Barrier. The cooldown will be refreshed.
    • Blazing Barrier absorbs Pyro damage 250% more effectively. 
    • The maximum damage absorption of the Barrier does not exceed a certain percentage of Thoma’s max HP.

Crimson Ooyoroi (Elemental Burst)

  • Thoma slices his enemies with quick Pyro AOE attacks.
  • Also casts a protective Scorching Ooyoroi shield.
    • Normal attacks from active characters affected by Scorching Ooyoroi trigger Fiery Collapses (one per second).
    • Fiery Collapses deal additional AOE Pyro damage and summon Blazing Barriers. 
    • The Blazing Barriers triggered by the Elemental Burst absorb less damage than the ones triggered by his elemental Skill. Other than that, the effects are the same. 

Imbricated Armor (Passive 1) – Ascension 1

  • Whenever your active character obtains or refreshes a Blazing Barrier, their shield strength increases by 5% for a duration of six seconds. This effect can stack up to five times and may occur once per 0.3 seconds.

Flaming Assault (Passive 2) – Ascension 4

  • Damage dealt by Fiery Collapses (Elemental Burst) is increased by 2.2% of Thoma’s max HP.

Snap and Swing (Passive 3) – Unlocked

  • If you catch a fish in Inazuma, there’s a 20% to obtain double the catch.

Weapon Options

As your new Pyro Support’s shield strength and Elemental Burst damage scale with HP, it seems like the most obvious secondary stat to go for. However, there’s currently only one Polearm with an HP secondary in Genshin Impact, and that’s the 3-Star Black Tassel. Its passive is pretty much useless, but the HP boost still makes it a great option for Thoma.

Of course, those of you with more 4-Star and 5-Star weapons may prefer an Energy Recharge secondary stat. Both The Cath and Engulfing Lightning are good options if you rely on Thoma’s Elemental Burst damage. But the Staff of (T)Homa is arguably the best, as it increases Attack Power based on max HP.

Staff of Homa (5-Star) – Increases Critical Damage and HP. Also provides an Attack bonus based on max HP. This bonus will be increased if the wielder’s HP is below 50%. 

Engulfing Lightning (5-Star) – Increases Energy Recharge. Furthermore, increases Attack by up to 56% of Thoma’s additional Energy (above the 100% threshold). The max bonus is 120%. Furthermore, you will gain 30 to 50% Energy Recharge for 12 seconds after using an Elemental Burst.

The Catch (4-Star) – Increases Energy Recharge as well as Elemental Burst damage and Elemental Burst Critical Rate. 

Black Tassel (3-Star) – Grants a high HP bonus as its secondary stat. Also increases damage dealt against Slimes.

Best Thoma Artifacts

There are more than enough Artifact sets for Thoma, but a two-piece Tenacity of the Millelith and Emblem of Severed Fate is the most reliable option. It’s also your best choice if you want to maximize his Support role. 

However, if you want to build Thoma as a Pyro Sub DPS, you should combine Emblem of Severed Fate with Noblesse Oblige instead. You can even go for the full sets, but bear in mind that Thoma’s Energy Recharge is unlikely to be high, and he can’t use his Burst very often due to cooldowns. A better hybrid Support/Sub DPS option is Crimson Witch of Flames together with Tenacity of the Millelith.  

As for his stats, HP% is never a waste. However, you probably want to use the Sands of Eon slot for Energy Recharge, especially if you chose an Artifact set to enhance Burst damage. Also, it’s always a good idea to do some shield testing before you decide on your final build: there might be enough room to go for a Pyro bonus on the Goblet slot instead of more HP.

Tenacity of the Millelith – (2) Increases HP by 20%.

Emblem of Severed Fate – (2) +20% Energy Recharge. (4) Increases Elemental Burst damage by 25% of Energy Recharge. 

Noblesse Oblige – (2) +20% Elemental Burst damage. (4) All allies gain a 20% Attack increase for 12 seconds after Thoma uses his Elemental Burst. Effect doesn’t stack.

Crimson Witch of Flames – (2) Plus 15% Pyro bonus.

Best Team for Thoma

Well… this should be easy. Thoma is a passive shield Support with Pyro Vision, so he matches with most characters. Before you assign him the full Support role, remember that he may be used as a Sub DPS too. Early game Genshin Impact players may even use him as their main DPS for a while.  

Our new 4-Star Pyro goes well together with a strong main DPS like Tartaglia, Ayaka, or (in the absence of 5-Stars) Kaeya. Fill the other slots with Sub DPS characters (some crowd control ability would be handy), and perhaps a healer. 

As for Elemental Resonance, it’s always good to team our Kamisato Retainer up with another Pyro to get an Attack bonus. If you need more Support, consider using both Thoma and Bennett on the same team. Alternatively, a 5-Star like Diluc or a 4-Star like Xiangling would be great. 

Top Tier Team

  • Main DPS: Tartaglia/Childe, Diluc, Yoimiya, Ayaka
  • Sub DPS: Kazuha, Venti
  • Sub DPS/Support: Thoma, Bennett
  • Support: Kokomi, Xingqiu, Raiden Shogun (Elemental Burst Battery)

Budget Team

  • Main DPS: Kaeya, Aloy (Melt Reaction)
  • Sub DPS: Xiangling, Amber (Elemental Resonance), Sucrose
  • Sub DPS/Support: Thoma, Bennett
  • Support: Barbara

Talent Materials

  • Talent Level-Up Material: Teachings/Guide/Philosophies of Transience
  • Common Ascension Material: Treasure Hoarder/Silver Raven/Golden Raven Insignia
  • Weekly Material: Hellfire Butterfly

Constellation

Although Thoma’s individual Constellation levels don’t seem that impressive, put them together and they greatly increase his Elemental Burst strength (look at numbers one, two, four, and five). Furthermore, given his Support role, it’s the final one that truly stands out. Reaching Constellation level 6 would provide the whole team with a useful attack buff that’s super easy to trigger. You don’t really need any of this to get a good shield provider, but pulling a few extra Thoma’s wouldn’t be a bad thing.

  • Level 1 – A Comrade’s Duty: When a Blazing Barrier absorbs damage for any ally that isn’t Thoma, Thoma’s Elemental Skill and Elemental Burst cooldowns decrease by three seconds. This effect may occur once every 20 seconds.
  • Level 2 – A Subordinate’s Skills Elemental Burst duration increases by three seconds.
  • Level 3 – Fortified Resolve: Increases the level of the Elemental Skill by three, to a max upgrade level of 15.
  • Level 4 – Long-Term Planning: After using his Elemental Burst, Thoma restores 15 Energy.
  • Level 5 – Raging Wildfire: Increases the Elemental Burst level by three. Maximum upgrade level is 15.
  • Level 6 –  Burning Heart: When a Blazing Barrier is obtained or stacked, every ally’s Normal, Charged, and Plunging Attack damage is increased by 15% for a duration of six seconds.
