Genshin Impact Thoma Guide: Ascension, Talent Materials, Best Weapons, Artifacts

Genshin Impact Thoma

Thoma is the new pyro 4-star character that is on the same banner as Hu Tao. If you wanted to get Hu Tao or rolled on the new banner then chances are that you have Thoma and are now looking to build him. In this Genshin Impact guide, we are going to go over the materials you need to level up Thoma and his talents and recommend a build for him.

Genshin Impact Thoma Ascension And Talent Materials

The following are the ascension and talent materials that you need in order to level up Thoma and upgrade his talents.

Ascension Materials

The following are the ascension materials that you need in order to level up Thoma to 90:

  • 1x Agnidus Agate Sliver
  • 9x Agnidus Agate Fragment
  • 9x Agnidus Agate Chunk
  • 6x Agnidus Agate Gemstone
  • 46x Smoldering Pearl
  • 168x Fluorescent Fungus
  • 18x Treasure Hoarder Insignia
  • 30x Silver Raven Insignia
  • 36x Golden Raven Insignia

You can get Agnidus Agate Sliver and higher-tier variants of the resource by beating the Pyro Regisvine and Pyro Hypostasis bosses. Each encounter with these bosses is going to take a considerable amount of resin so be sure to have transient resin or fragile resin if you want to farm these bosses quickly. Once you have the base resources, you can use the crafting station to convert them into higher-tier variants. The Pyro Hypostasis boss also drops Smoldering Pearl, so this is the boss that you need to prioritize. 

Fluorescent Fungus is exclusive to Tsurumi Island. You can find it in the wild. Treasure Hoarder Insignia and higher-tier variants of the resource can be farmed by beating Treasure Hoarders. Once you have the base resources, you can convert them into the higher-tier variants at the crafting station. 

Talent Materials

The following are all the talent materials that you need to level up all of Thoma’s talents:

  • 9x Teachings of Transience
  • 63x Guide to Transience
  • 114x Philosophies of Transience
  • 18x Treasure Hoarder Insignia
  • 66x Silver Raven Insignia
  • 93x Golden Raven Insignia
  • 18x Hellfire Butterfly
  • 3x Crown of Insight

You can get Hellfire Butterfly by beating La Signore in the Narukami Island: Tenshukaku domain. You can only get rewards from this domain once a week. If you have other drops from the domain then you can convert them into Hellfire Butterfly at the crafting station if you have Dream Solvent. Crown of Insight can be earned via special events and by leveling up the shrine tree in Inazuma. 

Best Genshin Impact Thoma Build

Leveling up Thoma and upgrading his talents is not going to be enough. You also need the right weapon and artifacts. The following is the build that we recommend for Thoma in Genshin Impact:

Best Weapons

Staff of Homa is the best weapon that you can get for Thoma. It is on the weapons banner right now so you have a chance of getting it if you already do not have it. This is a 5-star weapon so you do need to spend a lot of Primogems on the weapon banner in order to get it. Staff of Homa has crit damage as the bonus stat which is ideal for dealing high amounts of damage. It increases max HP by 20% and increases your attack depending on your max HP. The buff is further increased when the HP of the wielder is less than 50%.

Skyward Spine is another 5-star weapon that we can recommend that has energy recharge as the bonus stat. It increases crit rate by 8% and normal attack speed by 12%. When normal and charged attacks hit an enemy, there is a 50% chance of creating a vacuum blade that deals 40% of attack as damage in a small area of effect. This can only happen once every 2 seconds. 

The Catch is a great 4-star weapon that you can get if you are not interested in spending your Primogems on the weapons banner. It has energy recharge as the bonus stat and it increases elemental burst damage by 16% and elemental burst crit rate by 6%.

Favonius Lance is another great 4-star weapon that we can recommend. It has energy recharge as the bonus stat and crit hits have a 60% chance of creating a small number of energy particles. 

Best Artifacts

We can recommend going with 2 pieces of Emblem of Severed Fate and 2 pieces of Tenacity of the Millelith. This is going to increase your energy recharge and HP by 20%. We recommend energy recharge on the sands, HP% on the goblet, and HP% on the hat.

Alternatively, you can go with 2 pieces of Tenacity of the Millelith and 2 pieces of Crimson Witch of Flames. This is going to increase HP by 20% and pyro damage bonus by 15%. For this build, we recommend energy recharge on the sands, pyro damage bonus on the goblet, and crit rate or crit damage on the hat.

This is how we recommend building Thoma in Genshin Impact. If you want to learn more then you can check out our guide on how you should build Xinyan.
