Base Stats

Thoma is a 4-star Pyro character that wields a Polearm in Genshin Impact. He excels as a support character, providing strong shields for the team through his Elemental Skill and Elemental Burst, the latter of which also deals coordinated Pyro attacks with the active character's Normal Attacks. Lore-wise, Thoma is the affable and reliable housekeeper for the Kamisato Clan of Inazuma and a well-known "fixer" in the nation.

Thoma's Tier & Rating

What Kind of Character is Thoma?

Thoma is as an Off-Field Pyro Support or Shielder who creates a Blazing Barrier with his Elemental Skill that can be made more durable through the use of Normal Attacks. After using his Elemental Shield, Thoma's Blazing Barrier or shield now pulses Pyro every time the On-Field character does Normal Attacks called a Fiery Collapse. Every time a Fiery Collapse is triggered, a new shield is created. This is 'merged' to any existing shield, inheriting the remaining damage absorption while also refreshing the duration.

Thoma at a glance has many use-cases and can be flexed into many teams. However there are very few teams where he is the absolute best in the slot as a shielder. He is currently the best Burgeon trigger or DPS, but that playstyle usually makes his Blazing Barrier weaker. His place in the meta also isn't very notable.

Rate Thoma!

Basics Of Using Thoma

Thoma is designed to be an Off-Field Pyro support with a Blazing Barrier or pyro shield that can continuously release waves of Pyro damage. Thoma wants to deploy the shield from his Elemental Skill first, then use his Elemental Burst to allow the active character's Normal Attacks to refresh the duration of the Blazing Barrier, which allows the shield to be stronger.

Elemental Burst is Required For Better Shields

Thoma's Blazing Barrier can be created with both his Elemental Skill and Elemental Burst. But it's his Burst that enables it to be durable. This is because the active character refreshes the shield's duration and stacks the remaining damage absorption of an existing Blazing barrier on to a new one.

By default, Thoma wants to have a lot of Energy Recharge since his Elemental Burst has high Energy cost, so equipping him with enough Energy Recharge% on his Artifacts or weapon should be prioritized.

Shield Scales with HP, Damage Scales with Attack

The Blazing Barrier bases its total DMG absorption based on Thoma's Max HP. Conversely, the Fiery Collapse (Pyro waves) only take into account Thoma's Attack. Because of the split in scaling, it can become difficult to build for both shield durability and DPS. It's typically better to focus on his utility as a shielder and support by equipping Artifacts with HP% and Energy Recharge% over offensive stats like CRIT Rate (unless you're using Favonius Lance).

Thoma's personal damage can be underwhelming, so maximizing his shielding abilities will result in better results.

Can Be Played in Burgeon Teams

Thoma's kit has features that make him one of the better Pyro characters to for a (Dendro, Hydro and Pyro) team. The Blazing Barrier can help with the self-damage inflicted by the Burgeon explosions, and his Fiery Collapse, that triggers with Normal Attacks, is an ideal source of Pyro to explode the Dendro Cores.

Thoma in Burgeon comps will build Elemental Mastery instead, since he's the main trigger of the Burgeon reaction in these teams. His shield's durability will naturally be compromised, so having a Hydro or Dendro healer is likely preferred in this case.

Roles & Playstyle of Thoma and His Strengths and Weakness

Off-Field Support Thoma

Thoma is primarily a shielder who provides a Pyro shield coupled with decent Pyro application. He wants to be paired with an On-Field DPS that uses Normal Attacks to consistently refresh his shield. He can also be played as the Pyro trigger in a Burgeon team with Elemental Mastery-focused Artifacts.

Pros and Cons of Off-Field Support Thoma

Best Build for Thoma

Thoma wants to be played Off-Field most of the time, with his weapon options focused on Energy to ensure his Burst is always available. See below for the recommendations.

Thoma's Build Depends on Purpose

Off-Field General Shielder Off-Field Burgeon Trigger

Weapon	Favonius Lance
Best Artifact	Noblesse Oblige x 4
Artifact Main Stats	Sands: Energy Recharge% or HP% Goblet: HP% Circlet: HP% or CRIT Rate with Favonius Lance
Priority Sub-Stat	ER% > CRIT Rate (with Favonius Lance) > HP% > Flat HP/EM
Recommended Team

Stat Goals For Off-Field Shielder Thoma

HP	30,000+ HP
Crit Rate	50%~ with Favonius Lance
Energy Recharge	210%~ without C4 170%~ with C4

Thoma's Energy needs are very often going to be on the higher end due to the Energy Cost. Because this is most important ability, supplying him with enough Energy Recharge% is recommended. You always want to have Thoma's Elemental Burst to be ready every rotation, since his shield might be the only sustain option or source of Pyro application. Having his C4 drastically lowers his Energy requirements. Including Hp% or Flat HP in his Artifacts should also help strengthen the durability of the shield.

Weapon	Kitain Cross Spear
Best Artifact	Deepwood Memories x 4
Artifact Main Stats	Sands: Energy Recharge% / Elemental Mastery Goblet: Elemental Mastery Circlet:Elemental Mastery
Priority Sub-Stat	Energy Recharge% > HP% > Elemental Mastery
Recommended Team

Stat Goals For Off-Field Burgeon Trigger Thoma

Elemental Mastery	800~
Energy Recharge	210%~ without C4 170%~ with C4

Thoma's best Burgeon team at this point in the game includes Kinich, who can effectively trigger his Fiery Collapse in his grappled mode. Thoma is equipped with Deepwood Memories in this team to shred Dendro RES for Kinich. If you're running a different Burgeon team, you can opt to give Thoma Flower of Paradise Lost or Gilded Dreams instead to maximize the Burgeon damage. You can also consider getting HP% main-stat Artifacts instead if Thoma in a Burgeon team is the only sustain.

Best Weapon for Thoma

Thoma primarily wants to have weapons that can provide him Energy to charge his Elemental Burst. The best weapon will depend on how you plan to use him.

Off-Field General Shielder On-Field Burgeon Support

Premium Weapons for Off-Field Shielder Thoma

	Weapon	How to Get Rating
Best	Favonius Lance	Get from Banners - Energy Recharge% helps Thoma get his Elemental Burst up quicker and more consistently. - Passive provides Energy for everyone on his team including himself. - Thoma will need some CRIT Rate to activate the passive often.
2nd	Skyward Spine	Get from Banners - Energy Recharge% stat can make it easier for Thoma to have his Elemental Burst available for use every rotation. - No further team utility, which lowers its rank against Favonius Lance, but it's something you can use if you don't have any other choice.

Like most characters who are dependent on their Elemetal Bursts, the Energy given by the Favonius Lance's passive allows Thoma to meet his high Energy requirements, while his other teammates also benefit from the Energy Particles. So long as you have enough CRIT Rate to ensure the passive can be triggered constantly, Thoma can be a reliable Shielder that can generate Energy for his party. Other Energy weapon options such as the Skyward Spine is viable, but the polearms that lean more towards damage might be better on actual DPS characters, unlike Thoma.

Free To Play Friendly (F2P Weapons) for Off-Field Shielder Thoma

	Weapon	How to Get Rating
Best F2P	Kitain Cross Spear	Inazuma Forgeable (Craftable) Weapon - Provides Energy that'll let Thoma charge his Burst more consistently. - Best at R5 - Elemental Mastery on shielder Thoma isn't the best, but the Energy gain is still useful.
2nd F2P	Black Tassel	Get From Banners or After Finishing an NPC's Dialogue - One of the few Polearms with HP% as the secondary stat, which strengthens Thoma's shield. - Passive isn't anything noteworthy. - No form of Energy gain.
3rd F2P	Rightful Reward	Fontaine Forgeable (Craftable) Weapon - Has an HP% secondary stat. - Gives Energy whenever Thoma receives healing. - Thoma as a shielder is usually the main sustain and isn't typically going to be paired with healers, making it less than ideal. - Best at R5.

For Free-to-Play options, Thoma will appreciate the Energy he receives from the Kitain Cross Spear. Though he doesn't have use for the Elemental Mastery secondary stat for general shielding, it's still an option since it lets him meet his Energy requirements. The next options are viable due to the HP% that can make his Blazing Barrier more durable, but you'd need to have a lot of Energy Recharge% on his Artifacts.

Premium Weapons for Off-Field Burgeon DPS Thoma

	Weapon	How to Get Rating
Best	Dragon's Bane	Get from Banners - Gives Thoma Elemental Mastery. The more EM he has, the better the damage of the Burgeon Explosions. - No means of gaining Energy. Thoma still needs his Elemental Burst as a Burgeon support, so you may need a lot of Energy Recharge% with this weapon.
2nd	Favonius Lance	Get from Banners - Gives a lot of Energy Recharge%. - Allows Thoma to reliably use his Burst, which he uses often in a Burgeon team for Pyro application. - No Elemental Mastery provided, which may lower the damage of the Burgeon explosions. - Thoma needs some CRIT Rate to trigger the passive.

Thoma in a Burgeon comp is the main source of Pyro application, thus the trigger of the reaction. Because this is the case, he wants to still be able to use his Elemental Burst consistently every rotation for the Pyro. Dragon's Bane is a decent option, but has no Energy gain in its passive. Conversely, Favonius Lance is the go-to for Energy needs, but doesn't give Elemental Mastery, which increases Burgeon damage.

Free To Play Friendly (F2P Weapons) for Off-Field Burgeon DPS Thoma

	Weapon	How to Get Rating
Best F2P	Kitain Cross Spear	Inazuma Forgeable (Craftable) Weapon - Has an Elemental Mastery stat that Thoma wants in a Burgeon comp. - Has an Energy gain passive that helps Thoma meet his Energy requirements. - Best at R5

For Free-to-Play options, the Kitain Cross Spear is the best option by a good margin. There aren't a lot of polearms that provide Elemental Mastery, and this weapon can also provide Energy on top of it, making it the best weapon overall for Thoma as a Burgeon support. Since its a craftable weapon, its very accessible for Free-to-Play Travelers, but you would need to first unlock Inazuma and then complete the Orobashi's Legacy Quest.

Thoma Best Artifacts

Thoma's Artifact choices will depend on how you want to use him and who the On-Field DPS will be. See the recommendations below:

Off-Field Shielder Artifacts Off-Field Burgeon DPS Artifacts

Artifact	Recommendation Details
Noblesse Oblige	★★★★★ - Lets Thoma provide more utility through an ATK% buff after he uses his Elemental Burst. - Best generalist set that works with On-Field DPSes that want Attack, like Arlecchino.
Deepwood Memories	★★★・・ - Allows Thoma to shred Dendro RES. - The ideal choice if you play Thoma with Kinich.
Instructor	★★★・・ - Provides Elemental Mastery when Thoma triggers a reaction. - Good for On-Field DPSes that can appreciate the extra Elemental Mastery like Wriothesley in a Melt comp.

Artifact	Recommendation Details
Flower of Paradise Lost	★★★★★ - Best choice for maximizing the damage of the Burgeon explosions while also providing Elemental Mastery.
Gilded Dreams	★★★★・ - Decent alternative to the Paradise Lost set since it still gives Elemental Mastery.
2-pc. Elemental Mastery 2-pc. Elemental Mastery	★★・・・ - This set is a combo of 2 piece Elemental Mastery, which is good if you want Thoma still have decent Elemental Mastery for Burgeon damage. - Can be a temporary set while you farm for a better 4-piece set.

Recommended Artifact Stats

	Main: Flat HP Sub: Energy Recharge% / HP% / CRIT Rate (with Favonius Lance) / Elemental Mastery (in Burgeon team)
	Main: Flat ATK Sub:Energy Recharge% / HP% / CRIT Rate (with Favonius Lance) / Elemental Mastery (in Burgeon team)
	Main: Energy Recharge% or HP% Sub: Energy Recharge% / HP% / CRIT Rate (with Favonius Lance) / Elemental Mastery (in Burgeon team)
	Main:HP% Sub: Energy Recharge% / Flat HP / CRIT Rate (with Favonius Lance) / Elemental Mastery (in Burgeon team)
	Main: HP% or CRIT Rate (for Favonius Lance) Sub: Energy Recharge% / HP% / CRIT Rate (with Favonius Lance) / Elemental Mastery (in Burgeon team)

For Sub-Stats, Energy Recharge% Is the Most Important

Thoma wants Energy Recharge% for either of his playstyles, since they both want him to consistently use his Elemental Burst. HP% and Flat HP sub-stats are best for shielder Thoma because it bulks up his Blazing Barrier damage absorption. Elemental Mastery is more ideal for Burgeon Thoma due to Burgeons scaling off of this stat.

- A burgeon team comp for Thoma - Nahida and Ayato will provide continuous Dendro Cores - Thoma's slow Pyro application will insure you deal Burgeon instead of burning - Kazuha will be able to increase the team's damage and deal shred to enemies

Other Characters That Work With Thoma

Character	Sub	Details
Ayato	Childe Ayaka Itto	- Since Thoma's Pyro on-field attack sync with the active character normal attack, it's best paired with main DPS characters that utilize Normal Attacks - Not good with Pyro characters since Thoma might end up stealing reactions from them instead
Nahida	Dendro Traveler Xingqiu Chongyun	- Thoma can work with most characters who have on-field abilities - This doesn't apply only to Burgeon, but you do have the risk that Thoma might steal reactions. This is not ideal since Thoma has a lower damage multiplier
Kazuha	Sucrose Venti	- Since you want Thoma for reactions, he works really well with Anemo characters who also run EM or those that deal Elemental shred

Notes About Team Comps For Thoma

Thoma has a very limited pool of characters he can work with due to his kit working best with those that deal Normal & Charged Attacks. There's also the concern that due to his Pyro application being relatively slow, he might end up stealing reactions, lowering the team's DPS.

Team Rotation of Thoma and Combos

Basic Team Rotation for Off-Field Thoma

Thoma usually wants to be deployed at the start of the rotation, before the On-Field DPS and other supports due to his longer durations and cooldowns Note that if your On-Field DPS wants to activate their skill at the start, like Arlecchino or Mavuika, then it's fine to use Thoma after instead of the start.

This rotation should also still apply for both normal shielder Thoma and Burgeon Thoma teams.

Elemental Skill, Burst and Abilities Guide for Thoma

How To Use Thoma Skills & Passives

Pyro Shielder That Can Apply Off-Field Pyro

Thoma's shield is fairly strong with the right setup, and has Pyro application that can be useful in specific teams. If you have Thoma on the Kitain Cross Spear, then starting with his Elemental Burst into his Skill allows you to trigger the Energy passive easily. You want to use your other supports' abilities first if Thoma has Kitain.

Elemental Skill Provides the Initial Shield

Thoma usually prefers to start his combo with his Elemental Skill to trigger the initial Blazing Barrier.This will let him catch the Energy Particles generated by his Skill. The shield made by his Elemental Skill is noticeably less durable without the Elemental Burst refreshing it, however, so its important to have his Elemental Burst ready.

Elemental Burst Refreshes the Shield and Adds Pyro Application

Thoma's full Elemental Skill into Burst combo is a key part of his team's rotation. The Burst creates a new Blazing Barrier each time the On-Field character triggers Fiery Collapse, which are the Pyro waves that follow your On-Field character's Normal Attacks. Any leftover damage absorption from an existing Blazing Barrier stacks with the new one. The Blazing Barrier's duration is also refreshed. This results in a stronger shield as long as the On-Field DPS keeps using Normal Attacks.

Thoma in Burgeon Teams Wants Elemental Mastery Over HP%

While it's range is limited, the Pyro application from Fiery Collapses are enough to trigger Burgeon reactions, which makes Thoma the ideal Pyro character for Burgeon teams. He wants to be built with Elemental Mastery instead of HP% in these teams, which is good for increasing the damage dealt by the Burgeon explosions, but makes his shield less durable. It's better to rely on a healer for survivability if you play Thoma this way.

Should You Pull for Thoma's Constellation Or Best Weapon?

Aim for C4 if You're Able To

C4 Is Ideal for Thoma's Best Use-Cases

Thoma is very reliant on his Burst to sustain his "Blazing Barrier" and for Pyro application, and C4 refunds a decent amount of Energy that results in less Energy Recharge requirements for consistent Burst uptime. This constellation lets you invest into other stats (such as HP for better shields) instead of Energy Recharge, and it should yield good results in the teams that would benefit from having Thoma's Burst always up. Anything beyond C4 is a good bonus to have, with the buff from C6 being good for Normal, Charged and Plunge on-fielders respectively.

Note that constellation levels will not be strictly required if you are content with how he functions at C0. If you want to improve Thoma's performance in his given role, however, then going to C4 is highly recommended.
