Looking for the best Thoma build? The famous fixer and Kamisato housekeeper is no stranger to those who’ve played through the Genshin Impact Inazuma storyline.
Thoma is a four-star character with a Pyro vision and features alongside Hu Tao on the second Genshin Impact banner of the 2.2 update that went live on November 2. You’ll still be able to get him after his banner ends, but he won’t have an increased drop rate unless he’s featured on the special wish banner again.
Thoma’s elemental skill and elemental burst both summon a Pyro shield to protect the active character. The damage absorption of this shield scales with Thoma’s max HP. His burst has a high Pyro damage potential, which partly scales with max HP again, thanks to his Flaming Assault passive. This means you can build him as a shield support character or a Pyro DPS character – here are the best Genshin Impact Thoma builds for both roles.
Genshin Impact Thoma shield support build
The best Genshin Impact Thoma support build is:
- Polearm: Black Tassel or Staff of Homa
- Artifacts: Tenacity of the Millelith (two-set) and Emblem of Severed Fate (two-set)
The three-star Black Tassel is the best weapon for our Thoma support build, as this is the only polearm in the game with HP% as a secondary stat. No other weapon is quite as capable of boosting Thoma’s shield strength, as his shield power scales with his HP.
However, if you don’t want to go without a high base attack and useful passive ability, you can also choose the five-star Staff of Homa. It doesn’t grant as much extra HP as the Black Tassel, but a fully refined Staff would come pretty close. Furthermore, this weapon boosts Thoma’s attack power based on his max HP. It’s not strictly necessary for a shield support, but isn’t a waste either.
The first artifact set we recommend is the two-piece Tenacity of the Millelith, which grants a 20% HP bonus. Unfortunately, the four-piece set won’t work well for Thoma as he can’t trigger the effect often enough. A much better option for this shield support build is a two-piece Emblem of Severed Fate. This will help you recharge Thoma’s elemental burst faster, which means more shielding.
Unsurprisingly, we recommend aiming for a high HP stat on both the Goblet of Eonothem and Circlet of Logos slots to strengthen the shield as much as possible. Thoma’s burst also casts his shields, so we want to make sure he can use this whenever the cooldown ends, so it’s best to get an energy recharge stat on the Sands of Eon slot instead of a third HP%.
Genshin Impact Thoma Pyro DPS build
The best Genshin Impact Thoma DPS build is:
- Polearm: Engulfing Lightning
- Artifacts: Noblesse Oblige (two-set) and Crimson Witch of Flames (two-set)
If you don’t want to focus on Thoma’s shield ability, you can also build him to capitalise on his Pyro damage by focusing on his elemental burst. After his initial burst damage – which is already significant – the active character’s normal attacks trigger additional Pyro area-of-effect attacks for 15 seconds. This effect remains even after Thoma leaves the battlefield, which is great for triggering elemental reactions.
Thoma’s elemental burst only has a 20-second cooldown, but it does have a high cost: 80 energy. Luckily, a polearm such as the five-star Engulfing Lightning can fix this with its secondary energy recharge stat. This weapon will also boost Thoma’s attack power based on his extra energy (over 100%).
As we’re focusing on Pyro and burst damage, the best artifact sets to use are the two-piece Noblesse Oblige, which increases elemental burst damage by 20%, and the two-piece Crimson Witch of Flames, which increases Pyro damage by 15%. If you need more energy recharge, you can swap one of these for a two-piece Emblem of Severed Fate set.
Ideally, you should go for energy on the Sands of Eon slot in this build. It enables you to use your elemental burst as soon as the 20-second cooldown ends, and any excess energy enhances your attack if you’re using the Engulfing Lightning polearm. On the Goblet slot, prioritise Pyro damage. Critical damage is the best choice on the Circlet slot, but go for critical rate instead if you don’t have enough.
Whether you choose to build him as a shield support or Pyro DPS, the best Genshin Impact Thoma builds will make him a worthy addition to your team.
