General information

Thoma is a 4-star Pyro character in Genshin Impact, wielding a polearm and primarily serving as a support unit. His unique abilities allow him to create shields that absorb damage and apply Pyro damage over time, making him particularly effective in teams focused on Burgeon reactions. Thoma’s elemental skills scale with his max HP, enhancing his shielding capabilities while providing consistent off-field Pyro application. This guide will explore Thoma’s optimal builds, including weapon choices, artifact sets, and team compositions to maximize his potential in various gameplay scenarios.

Thoma is a four-star character who fights using Polearms. Thoma is best known as a Support who assists others with his shields that scale with his HP, but he can also be a Sub DPS. Unfortunately, his scaling with DMG is not that high, so he cannot become a Main DPS.

You should focus on stats like HP and Energy Recharge if you want to build him as a Support, and in the case of Sub DPS, focus on ATK, Pyro DMG and CRIT DMG.

Best compositions

Thoma excels in Genshin Impact as a versatile character capable of both shielding and dealing Pyro damage, making him an invaluable asset in various team compositions. Best compositions for Thoma include builds that leverage his unique abilities to create shields while applying Pyro damage effectively. For a support role, pairing him with characters like Hu Tao or Kamisato Ayato can maximize damage output through Vaporize and Burgeon reactions. His optimal weapon choices, such as the Kitain Cross Spear or Favonius Lance, enhance his Energy Recharge and Elemental Mastery, allowing for consistent shield uptime and Pyro application. Utilizing artifact sets like Flower of Paradise Lost or Noblesse Oblige can further amplify his effectiveness in both support and damage-dealing roles, ensuring he remains a top-tier choice for team synergy in challenging encounters.

Sub DPS – Hu Tao/Thoma/Jean/Xingqiu

Pyro Support Build

Thoma excels as a Pyro Support Build in Genshin Impact, primarily functioning as a shield provider while also enabling powerful elemental reactions. His abilities, particularly the Blazing Blessing and Crimson Ooyoroi, create shields that absorb damage and apply Pyro damage over time, making him invaluable in Burgeon teams. For optimal performance, focus on weapons like the Kitain Cross Spear or Favonius Lance, which enhance his energy recharge and HP, thereby boosting his shield strength. Artifacts such as Tenacity of the Millelith and Emblem of Severed Fate are recommended to maximize his support capabilities while ensuring consistent Pyro application for triggering elemental reactions without overwhelming the battlefield with excessive burning effects.

In the case of building Thoma as a Support, it is important to get him a large amount of Energy Recharge, so he will be able to create Shields for other characters. In addition, it is worth focusing on HP, since the Shield scales precisely with this statistic.

Artifacts – 4x Noblesse Oblige/2x Emblem of Severed Fate and 2x Tenacity of the Millelith
Weapons – Skyward Spine/Favonius Lance

Thoma as Support needs a large amount of Energy Recharge – Noblesse Oblige set works perfectly with a large amount of Energy Recharge. Thanks to the large amount of Energy, you will be able to use Elemental Skill and Burst much faster and more often, and this set will strengthen your Elemental Burst DMG by 20% if you have 2 parts. If you have 4 parts, after using Elemental Burst, you will increase the ATK of each character by 20% for 12 seconds – a very good buff for someone who is only supposed to help others in battle.

There is also a combination of Emblem of Severed Fate and Tenacity of the Millelith sets. The two parts of EoSF give 20% Energy Recharge, and the two TotM will give you 20% HP. This is one of the better set combinations you can make for Thoma, because, as a Support, you need a lot of Energy Recharge to use the Shields and HP to make them much stronger.

In the case of weapons for Thoma as Support, it is worth investing in Skyward Spine provided you have it. Besides the basic ATK, it also gives a large amount of additional Energy Recharge. Moreover, it increases CRIT Rate by 8%, Normal ATK SPD by 12%, and in addition, attacks have a 50% chance to deal additional 40% DMG AoE. However, this is not so important, since Thoma will not be in your team as a Support to perform too much attacks. This weapon is ideal if you have a lot of Energy Recharge.

A slightly weaker version of the weapon, although offering an additional amount of Energy Recharge, will be Favonius Lance. This weapon has a much better ability, because during a critical attack, you have a 60% chance of creating an Elemental Orb, which will recover 6 Energy to a character that will pick up this orb.

Sub DPS Build

Thoma’s Sub DPS Build in Genshin Impact focuses on maximizing his Pyro damage output while maintaining his supportive role. Utilizing weapons like the Engulfing Lightning or Kitain Cross Spear, this build enhances Thoma’s elemental burst capabilities, allowing for significant AoE Pyro damage. The ideal artifact sets include Noblesse Oblige and Crimson Witch of Flames, which boost elemental burst damage and overall Pyro damage, respectively. Prioritizing stats such as Energy Recharge and Elemental Mastery ensures that Thoma can consistently apply Pyro for elemental reactions while also contributing to team damage through his burst abilities, making him a versatile asset in various team compositions.

Thoma is not very suitable as a main DPS since he has very small DMG converter. However, a properly build Thoma can be ideal as a Sub DPS in combination with a Support.

Artifacts – 4x Emblem of Severed Fade
Weapons – Engulfing Lightning/The Catch

Emblem of Severed Fade set adds 20% Energy Recharge and increases Elemental Burst DMG by 25% of current Energy Recharge, up to a maximum of 75%. These artifacts perfectly match with the previously mentioned weapons, which additionally offer Energy Recharge and work great with this statistic.

Engulfing Lightning is a five-star weapon. Not only does it increase the potential for damage, it also works well with high Energy Recharge. The weapon itself gives you extra Energy Recharge, plus it boosts your ATK based on how much Energy Recharge you have, up to a maximum of 80% (a maximum of 120% at Refinement level 5). Moreover, after using Elemental Burst, you will receive 30% Energy Recharge (max 50%). The weapon works great when combined with Emblem of Severed Fade.

The second weapon, The Catch, also offers Energy Recharge, however slightly less than Engulfing Lightning. However, it is worth mentioning that it is easier to get, since it is a four-star weapon. This weapon also offers an Elemental Burst DMG increase by 16% (up to 32%) and Elemental Burst CRIT Rate by 6% (up to 12%). With so much Energy Recharge, you can easily use Elemental Burst to deal as much damage as possible.

Talents

Thoma, a 4-star Pyro Polearm user in Genshin Impact, excels in providing shields and enabling elemental reactions, particularly Burgeon. His talents are designed to enhance his role as a support character, with abilities that not only absorb damage but also apply Pyro damage through his elemental skills. Thoma’s Elemental Skill, Blazing Blessing, generates a protective barrier while dealing AoE Pyro damage, making him invaluable for team survivability. His Elemental Burst, Crimson Ooyoroi, further amplifies his shielding capabilities and allows for continuous Pyro application during normal attacks, effectively supporting characters reliant on elemental reactions. Prioritizing his talents will significantly enhance his effectiveness in battle, especially when built around maximizing Energy Recharge and Elemental Mastery for optimal performance in Burgeon teams.

Talents are abilities that each character in the game uses. When it comes to Thoma, Talents should be improving in the right order:

Blazing Blessing, Crimson Ooyoroi

In the case of the Support build, you should not waste resources on Swiftshatter Spear, as you will not use Normal or Charged ATK too much.

Constellations

Thoma’s Constellations enhance his abilities and overall effectiveness in combat, particularly as a support character in Genshin Impact. Each Constellation level provides unique benefits, such as reducing cooldowns and increasing damage absorption for his shields. For instance, at Constellation Level 1, “A Comrade’s Duty,” Thoma gains a significant boost to his shield’s effectiveness, while Level 4, “Long-Term Planning,” enhances the duration of his Elemental Burst. These upgrades not only improve Thoma’s survivability but also allow him to synergize better with other characters in Burgeon teams, making him a versatile choice for various team compositions.

Thoma, as one of the few four-star characters, is very helpful with C0. His constellations mainly extend the effects, strengthen the shields, or lower the requirements needed to use certain skills.

What are the key differences between Thoma’s shield support and Pyro DPS builds

Thoma in Genshin Impact can be built primarily as a shield support or a Pyro DPS character, each focusing on different aspects of his abilities. Here are the key differences between these two builds:

Shield Support Build

Primary Role: Thoma’s shield support build emphasizes his ability to provide robust shields to teammates. His shields, created by both his Elemental Skill and Elemental Burst, scale with his max HP, making him an excellent choice for protecting characters that rely on normal attacks, such as Hu Tao and Xiao.
Artifact Sets: The recommended artifact sets for this build are Tenacity of the Millelith (for increased HP) and Emblem of Severed Fate (to enhance energy recharge), allowing Thoma to maintain high shield uptime and quickly regenerate his Elemental Burst.
Weapons: Ideal weapons include the Black Tassel, which boosts HP, or the Staff of Homa, which provides attack bonuses based on HP. The focus here is on maximizing shield strength rather than offensive capabilities.
Gameplay Focus: This build excels in providing consistent shielding and interruption resistance, allowing on-field characters to maintain their damage output without being staggered. However, it has limited damage output compared to dedicated DPS characters.

Pyro DPS Build

Primary Role: In contrast, the Pyro DPS build focuses on maximizing Thoma’s damage potential through his Elemental Burst, which deals significant AoE Pyro damage and triggers additional Pyro attacks during normal attacks from the active character.
Artifact Sets: For this build, players typically use Noblesse Oblige (to boost burst damage) and Crimson Witch of Flames (to enhance Pyro damage), enabling Thoma to contribute effectively to elemental reactions like Vaporize and Burgeon.
Weapons: The best weapon for this build is often the Engulfing Lightning, which increases Thoma’s energy recharge and attack power based on energy levels. This weapon synergizes well with his burst-focused playstyle.
Gameplay Focus: This build allows Thoma to deal substantial Pyro damage while still providing some shielding. However, it requires careful management of energy and cooldowns due to Thoma’s high energy costs for his abilities.

In summary, choosing between Thoma’s shield support and Pyro DPS builds depends on your team composition and desired role in combat. The shield support build prioritizes protection and utility, while the Pyro DPS build focuses on maximizing damage output through elemental reactions.

Which characters benefit most from Thoma’s shield support

Thoma’s shield support in Genshin Impact is particularly beneficial for characters who rely heavily on normal attacks and are vulnerable to interruptions. Here are the key characters that benefit the most from Thoma’s shielding abilities:

Characters That Benefit from Thoma’s Shield Support

Hu Tao: As a Pyro DPS character, Hu Tao performs frequent normal attacks during her elemental skill’s duration. Thoma’s shields provide her with the necessary protection to maintain her damage output without being interrupted.
Xiao: This Anemo DPS character often engages in close combat and can be vulnerable to enemy attacks. Thoma’s shields allow Xiao to unleash his powerful plunging attacks while reducing the risk of being staggered.
Yoimiya: Another Pyro character that focuses on normal attacks, Yoimiya benefits from Thoma’s shields, which help her maintain her damage output during her elemental skill and burst phases.
Ayato: While primarily a Hydro DPS, Ayato also relies on normal attacks for his damage. Thoma’s shielding allows him to perform his combos without fear of interruption, enhancing his overall effectiveness in combat.
Kazuha: As a support character who can deal significant elemental damage through swirl reactions, Kazuha benefits from Thoma’s shields, allowing him to stay on the field longer while maintaining his crowd control and damage capabilities.

Thoma’s shields not only provide strong damage absorption—especially against Pyro attacks—but also allow these characters to perform their roles more effectively by mitigating the risk of interruption during crucial damage windows.
