Thoma Best Team Combo

– Because of Thoma, Childe can recklessly attack enemies and will also increase Childe’s damage through reactions but it will not be consistent enough to proc constant Vaporize.

– Bennett will boost the attack of the team and also provide healing.

– Kazuha will keep the enemies within reach and is able to increase damage through Elemental Buff.

Best Thoma Builds in Genshin Impact

Thoma is best suited to the support role, more specifically, the shielding role. Not only does he shield his team from damage, but he can also be a consistent pyro enabler as mentioned.

Thoma’s kit revolves around him having high HP as even his fourth ascension passive taps into this, buffing his elemental burst’s damage using his max HP.

Best Weapons for Thoma in Genshin Imapct

As you may see, some of these weapons have Energy Recharge as their substat. This is due to Thoma having a very high energy requirement for his elemental burst. However, Staff of Homa towers all over them due to the sheer amount of HP it provides and the effect of the weapon itself.

Staff of Homa

Staff of Homa

HP increased by 20%.

Additionally, provides an ATK Bonus based on 0.8% of the wielder’s Max HP. When the wielder’s HP is less than 50%, this ATK Bonus is increased by an additional 1% of Max HP.

The Catch

The Catch

Best Artifacts for Thoma in Genshin Impact

Thoma benefits a lot from energy recharge. The ideal artifact sets for him would be a 2 piece Tenacity of the Millelith and a 2 piece Emblem of Severed Fates.

However, if you’re looking for more firepower, you can opt for 2 piece Crimson Witch of Flames and 2 piece Emblem of Severed Fates.

For mainstat priorities, go for HP% for Sands, Goblet, and Circlets.

FAQs about Genshin Impact Thoma

Thoma’s constellations are one of a kind, and even probably the only character in which each of the constellations provides extreme value.

Obtaining multiple copies of Thoma significantly increases his supportive capabilities, and is recommended if you have primogems to spare.

The age of Thoma is not obviously stated in the game. His birthday is on January 9th. 

Thoma’s shielding potential

Numbers-wise, Thoma has the second strongest shield in the game.

Thoma’s shield will surpass characters like Diona and Noelle when your shield is consistently refreshing, as his shields refresh off of Normal Attacks with his Elemental Burst.

According to the current rumors Thoma will return as part of the first banner of the upcoming 2.5 updates. This next banner will mainly be about the new 5-star character Yae Miko, but Thoma will be joined by fellow 4-star characters Fischl and Diona.

The best team composition to work with Thoma includes Tartaglia, Bennett, and Kazuha.
