How to Play Thoma in Genshin Impact

Thoma is the official housekeeper of the Kamisato Clan and a well-known “fixer” in Inazuma. He is the first character you will meet when you arrive in Inazuma and will guide and help you through the troubles that a newcomer to the Electro Nation faces.

Despite being almost always busy with matters such as cleaning and cooking in the Yashiro Commission, Thoma does not stay there but discreetly goes elsewhere to deal with some special matters. Such matters include solving the problems encountered by the Yashiro Commission, asking for information from the head of the Kamisato Clan, and fulfilling Ayaka’s wishes. In those unknown corners, Thoma has always used his way to develop the influence of the Yashiro Commission.

Although Thoma has a vast network of contacts, he has never used it for personal gain nor forced others to do things in the name of the Yashiro Commission. Because Thoma is from Mondstadt, he is often regarded as an “outsider” by the residents of Inazuma. But despite the strange looks and gossip directed towards him, Thoma never showed any dissatisfaction and always smiled at all doubts.

Thoma has always been taught by his father the importance of the word “loyalty.” When the Yashiro Commission’s Kamisato Clan lost power, he was offered to leave the clan and not get involved. Thoma responded that if he left at such time, he would lose his loyalty and righteousness and promised to do his best to do his part for the young master and the young lady.

The will to burn for loyalty and righteousness forged the gods’ attention. As I respond to Thoma’s choice – on this night of divergent destinies, a Vision, bright red like a blaze, appeared beside him.


How to Get Thoma in Genshin Impact

Thoma is a 4-star character added as a permanent 4-star item in all wish banners. Using Primogems, Acquaint Fates, and Intertwined Fates, you can make wishes on the Standard and Character Event Wish Banners to get a copy of Heizou. However, the best time to make wishes on the banner is when Thoma is one of the featured characters because the chance of getting him will increase.

Thoma’s Team Role and Play Style in Genshin Impact

Thoma is a supporting character who can help the team by creating a shield and dealing with damage while not on the field. His kit focuses on shield-making and enhancing the abilities of said shield. After creating a shield, you will surely switch to the DPS character of your team, putting Thoma back off-field.

A screenshot of Thoma in Genshin Impact

Thoma’s elemental burst enhances his shield with this playstyle so he can still throw Pyro attacks on the opponents even if he is not on the field.

Since Thoma has high Max HP in a coop play, he should tank and taunt the enemies to focus on him. He can take all the damage with his shield and let his teammates attack the opponents.

Thoma’s Talents in Genshin Impact

Combat Talents

Normal Attack: Swiftshatter Spear

This talent allows Thoma to perform up to four consecutive spear strikes.

When the attack button is held down, Thoma will lunge forward and deal damage to opponents along the way. This method will consume a certain amount of Stamina.

A gameplay still from Genshin Impact

Thoma will plunge to strike the ground below if this talent is used while he is at a certain distance from the ground. This will damage opponents along the path and deal AOE damage upon impact.

Elemental Skill: Blazing Blessing

As a guest from afar, only the burning passion would allow one to master Inazuma’s pure and precise spear arts. Thoma’s mastery is not limited to being the “swiftest-studying student” or “a master of the spear,” but he has imbued his will to protect others and fend off foes into his art.

A gameplay still from Genshin Impact

This talent will have Thoma vault forward with his polearm to deliver a flame-filled flying kick that deals AOE Pyro Damage. This action will also summon a defensive Blazing Barrier, which will apply Pyro to Thoma himself at the moment of casting.

A gameplay still from Genshin Impact

The damage absorption of the Blazing Shield scales off Thoma’s maximum HP and has the following traits:

  • Absorbs Pyro Damage 250% more effectively. This means this shield is stronger against Pyro attacks than against other elements, which makes it a good shield against Pyro Elemental opponents and environments.
  • When a Blazing Barrier is obtained, the remaining Damage Absorption of an existing Blazing Barrier will stack, and its duration will be refreshed.
  • The blazing Barrier shield can be carried over to other active characters in your team.
  • The maximum Damage Absorption of the Blazing Barrier will not exceed a certain percentage of Thoma’s Max.

As a shield-maker for your team, Thoma’s playstyle is to summon him to cast his elemental skill and then switch back to your DPS characters.

Elemental Burst: Crimson Ooyoroi

“I will not forget my initial promise. Let this burning flame protect those I cherish, and may it never be extinguished.”

Using this talent will have Thoma spin his polearm, slicing at his foes with roaring flames that deal AOE Pyro damage and weave themselves into a Scorching Ooyori.

While Scorching Ooyori is in effect, a Blazing Barrier will be summoned, and the active character’s Normal Attacks will trigger Fiery Collapse, dealing AOE Pyro Damage. Fiery Collapse can be triggered once every 1 second.

Except for the amount of Damage they can absorb, the Blazing Barriers created by Thoma’s elemental burst are identical to those created by his elemental skill, Blazing Blessing. The Blazing Barrier created this way will have the following properties:

  • Absorbs Pyro Damage 250% more effectively.
  • When a new Blazing Barrier is obtained, the remaining Damage Absorption of an existing Blazing Barrier will stack, and its duration will be refreshed.

The maximum Damage Absorption of the Blazing Barrier will not exceed a certain percentage of Thoma’s Max HP.

The best way to maximize the effects and properties of this talent is to use Thoma’s elemental skill before the shield created by his elemental burst disappears.

Thoma’s Passive Talents in Genshin Impact

Imbricated Armor

If this passive is unlocked, when your currently active character obtains or refreshes a Blazing Barrier, this character’s Shield Strength will be increased by 5% for 6 seconds. This effect can be triggered once every 0.3 seconds, with a maximum stack of 5.

The effect of this passive talent makes you want to spam the use of Thoma’s elemental skill, which will surely keep your active character protected.

Flaming Assault

This passive talent enhances the damage dealt by the Fiery Collapse triggered by Thoma’s elemental burst, Crimson Ooyoroi. The damage boost will be 2.2% of Thoma’s maximum HP.

Since all other active characters can trigger his elemental burst while Thoma is not on the field, this makes him a sub or off-field DPS character.

Utility Passive: Snap and Swing

Thom’s utility passive enhances your fishing abilities. With this unlocked, Thoma’s help grants a 20% chance of scoring a double catch when you fish successfully in Inazuma.

Thoma’s Genshin Impact Constellation: Rubeum Scutum

A screenshot of Thoma's Constellation in Genshin Impact

Constellation Level 1: A Comrade’s Duty

With this constellation level unlocked, when a character protected by Thoma’s Blazing Barrier is attacked, the cooldown time of Thoma’s elemental skill, Blazing Blessing, and his elemental burst, Crimson Ooyori, will be decreased by 3 seconds. However, this will not take effect if Thoma is the active character or the one hit by an opponent’s attack.

This effect can also only be triggered once every 20 seconds.

Constellation Level 2: A Subordinate’s Skills

Unlocking the second level of Thoma’s constellation will enhance his elemental burst. With this, the duration of Crimson Ooyori will be increased by 3 seconds. This gives the uptime of the shield created by his elemental burst.

Constellation Level 3: Fortified Resolve

Fortified Resolve is the 3rd level of Thoma’s constellation. With this unlocked, his elemental skill, Blazing Blessing, will be increased by 3, and its maximum level will be upgraded to 15.

Constellation Level 4: Long-Term Planning

Thoma’s constellation level 4 will help him spam his elemental burst because with this unlocked, every time he uses Crimson Ooyoroi, 15 Energy will be restored to him.

Constellation Level 5: Raging Wildfire

Raging Wildfire is the 5th level of Thoma’s constellation. With this unlocked, the level of his elemental burst, Crimson Ooyoroi, will be increased by 3, and its maximum level will be upgraded to 15.

Constellation Level 6: Burning Heart

The final level of Thoma’s constellation is called Burning Heart, and it will grant additional supporting capabilities to his elemental skill and elemental burst. With this unlocked, when a Blazing Barrier is obtained or refreshed, the damage dealt by all party members’ Normal, Charged, and Plunging Attacks will be increased by 15% for 6 seconds.

How to Build Thoma in Genshin Impact

A screenshot of Thoma in Genshin Impact

Max HP

Thoma’s shield has a damage absorption that scales off his Max HP, which means that to increase the strength of his shield, he needs a lot of HP.

Although he can deal Pyro Damage, the off-field damage he can provide also benefits from his amount of HP. This is due to his passive Talent called Flaming Assault, which increases the damage of the Fiery Collapse created by his elemental burst, Crimson Ooyoroi.

Physical and Pyro Damage (Not Recommended)

A non-conventional and not recommended build for Thoma is to increase his Physical damage. This may increase the damage of his normal and charged attacks but will compromise his shield’s strength.

You can also equip Thoma with items that give a Pyro Damage Bonus, increasing the damage of his elemental skill and burst. However, with his kit and playstyle, compromising his support capabilities to be a DPS character is not a good option.

Weapon: Polearm

The polearm is Thoma’s weapon, and the ones you need to equip him should increase the stats that boost his supporting capabilities. Among the existing and available polearms as of the writing of this article, you can choose between the damage-boosting ones and the ones that increase his Energy Recharge.

5-Star Polearms

Vortex Vanquisher

A screenshot of Vortex Vanquisher in Genshin Impact

This weapon’s passive effect, called Golden Majesty, increases the shield strength of the weapon user and increases that character’s ATK for a certain amount whenever that character hits an opponent. This effect can be stacked up to 5 times and doubled if a shield protects that character.

This effect may boost the strength of Thoma’s shield, but it is only active when he is on the field.

Engulfing Lightning

A screenshot of Engulfing Lightning in Genshin Impact

This time-limited 5-star weapon has energy Recharge as its secondary stat and a passive effect titled Timeless Dream: Eternal Stove that increases the ATK of the character by a certain percentage of Energy Recharge over the base 100%.

After using an elemental burst, the character will gain a 30% Energy Recharge for 12 seconds.

This polearm will not only allow Thoma to spam his elemental burst, despite having a high Energy Cost of 80, but also increase the talent’s damage based on his Energy Recharge. It works best with the Emblem of Severed Fate artifact set because it increases the user’s elemental burst damage based on their Energy Recharge.

Skyward Spine

A screenshot of Skyward Spine in Genshin Impact

Skyward Pride is a permanent 5-star item you can get by making wishes on the Standard and Weapon Banners if you are lucky enough.

This weapon’s secondary stat is Energy Recharge, and its passive effect, called Black Wing, will increase the character’s Critical Rate and Attack Speed. Additionally, when normal and charged attacks hit opponents, there will be a 50% chance that a vacuum blade will be triggered. The said vacuum blade will deal at least 40% of ATK as damage in a small AOE. Black Wing can occur no more than once every 2 seconds.

4-Star Polearms

The Catch

A screenshot of "The Catch" in Genshin Impact

The Catch is a weapon with Energy Recharge as its secondary stat and a passive effect titled Shanty that increases the elemental burst damage of the character and the Critical Rate of that skill.

This 4-star polearm is one of the weapons you can get for free by crafting it with the town smithy. All you need is to unlock the fishing mini-game feature of the game and catch the necessary materials for it.

This weapon is considered a good alternative to the Engulfing Lightning and sits well with Thoma’s playstyle, which involves using his elemental burst more often.

Prototype Starglitter

A screenshot of Prototype Starglitter in Genshin Impact

This polearm is a decent weapon for Thoma, especially when you cannot get any good weapon from the Wish Banners. This can be obtained by crafting with the town smithy as long as you have the necessary materials.

This weapon’s secondary stat is Energy Recharge, which can help prepare Thoma’s elemental burst. The passive effect of this weapon, Magic Affinity, increases the normal and charged attack of the character after using an elemental skill. This effect can be stacked up to 2 times.

However, Thoma cannot maximize this passive effect since Thoma’s elemental skill cools down time by 15 seconds, and Magic Affinity only lasts for 12 seconds.

Wavebreaker’s Fin

A screenshot of Wavebreaker's Fin in Genshin Impact

This is another 4-star spear that focuses on increasing the maximum ATK of the user. Watatsumi Wavewalker, the passive effect of this weapon, can be good due to the 90 Energy Cost of Thoma’s elemental burst. However, this effect will be maximized if the characters in the team also have elemental burst talents with high energy costs like his.

Favonius Lance

A screenshot of Favonius Lance in Genshin Impact

Thanks to its secondary stat, Favonius Lance is one of the weapons that increase the character’s Energy Recharge. Its passive effect called Windfall will allow Critical Hits to generate a small number of Elemental Particles, regenerating 6 Energy for the character using the weapon.

This effect, however, can only occur once every 2 seconds.

3-Star Polearm

Black Tassel

A screenshot of Black Tassel in Genshin Impact

If you do not mind using a very low base ATK for a weapon, you can choose to equip Thoma with the Black Tassel. This is a 3-star polearm with a secondary stat of HP. Although this weapon cannot increase Thoma’s overall damage output, its HP bonus can help strengthen the shield he creates.

Thoma’s Artifacts in Genshin Impact

4-Piece Sets

Tenacity of Millelith

A screenshot of Tenacity of the Millelith in Genshin Impact

This artifact set is designed for characters that focus on the main role as support, providing shield and off-field attacks with their elemental skills, like Zhongli.

The 2-piece set increases HP by 20%, and the 4-piece set increases all party members’ ATK and shield strength when the artifact user hits an opponent with an elemental skill. This effect can also be triggered even if the artifact user is not on the field.

Although Thoma can still trigger the 4-piece set effect of this artifact, he can only do this once every 15 seconds, which is the amount of time it takes for his elemental skill to cool down and be used again.

Emblem of Severed Fate

A screenshot of Emblem of Severed Fate in Genshin Impact

The 2-piece set of this artifact gives a bonus of 20% Energy Recharge, and if four pieces are equipped, the elemental burst damage of the character will be increased by 25% of the character’s Energy Recharge. A maximum of 75% bonus damage can be obtained in this manner.

With the 4-piece set of Emblem of Severed Fate equipped, the higher the character’s energy recharge, the higher the damage of their elemental burst will be.

A full 4-piece set of this artifact can be considered the artifact set for Thoma because he needs a boost to his Energy Recharge, and his play style involves spamming his elemental burst.

Noblesse Oblige

A screenshot of Noblesse Oblige in Genshin Impact

The Noblesse Oblige is a good artifact set for an off-field type Thoma with a play style that is more into throwing elemental burst attacks to the enemies.

With four pieces equipped, Thoma’s elemental burst damage will be increased by 20%, and when he uses the talent, all party members will have an ATK boost of 20% for 12 seconds.

Retracing Bolide

A screenshot of Retracing Bolide in Genshin Impact

The 2-piece set of the Retracing Bolide will increase the shield’s strength around the artifact user by 35%. With the 4-piece set, while a shield protects the character, they will gain an increase of 40% to the damage of their normal and charged attacks.

This artifact is designed for DPS characters who can summon a shield over themselves and deal damage with their normal or charged attacks. The play style of a DPS Noelle will benefit from the effects of the 4-pieces set of this artifact.

This set can work with Thoma in a co-op game setup where he is always on the field.

2-Piece Sets Combination

The tenacity of Millelith, Emblem of Severed Fate, and Crimson Witch of Flames

The 2-piece set of these artifacts can be combined for Thoma to have a decent build. The Tenacity of Millelith will increase his HP, Emblem of Severed Fate will boost his Energy Recharge, and Crimson Witch of Flames will grant him Pyro Damage Bonus.

You can try mixing and matching these 3 sets and see what works for you.

Artifact Parts’ Main Stat

Since the damage absorption of his shield and the bonus of the damage dealt by the Fiery Collapse both scales off Thoma’s HP, it is recommended to equip him with Circlet of Logos, Goblet of Eonothem, and Sands of Eon that have HP as their main stat.

For the Goblet of Eonothem, you can also choose one that gives Pyro Damage bonus, and it will still work fine with Thoma.

Thoma’s Character Ascension

What is Character Ascension in Genshin Impact?

Each character has a certain level cap depending on their current ascension phase, and a character can ascend to 6 phases to reach the maximum character level, which is 90. Passive talents and special ascension stats will also be unlocked when a character is ascended to certain phases.

It must have been the will of the world that Pyro Hypostases should constantly cool down and heat up because even the burning flames shall one day grow cold, and even the ashen firewood can will itself back into a raging blaze.

These things can be obtained by defeating the Pyro Hypostasis in its arena on the island northwest of Kujou Encampment in Kannazuka, Inazuma.

Thoma’s Talent Level-Up Materials

What are the Talent Level-Up Materials for Thoma

Aside from Mora and Treasure Hoarder Insignias, you will need a few Hellfire Butterflies to increase Thoma’s combat talents.

Hellfire Butterfly

A screenshot of Hellfire Butterfly in Genshin Impact

This material is a warped shard that houses great might, an original power that Crimson Witch of Flames then unleashed.

The seal of ice was broken under duress, and as her former will surged forth from its pale white prison and she remembered her old name once more, the undying butterfly danced amidst burning flesh and blood. And she remembered her past, wandering the land, spreading the flame, burning away all evil — and recalled the face of the person she could never meet again.

You can get a few of this material after defeating Signora in the Tenshukaku Memories: Duel to the Fiery Death Domain in Narukami Island, Inazuma.

Talent Level Book: Transience

The talent scrolls you will need for Thoma to master her combat capabilities are the ones of the “Transience” series, which you can obtain from the Violet Court Domain of Mastery: Reign of Violet in Narukami Island, Inazuma.

These scrolls include the Teachings of Transience, Guide to Transience, and the Philosophies of Transience. The last two can be crafted using the crafting bench in the town.

Crown of Insight
