What’s The Best Team For Thoma?

Thoma is a Pyro-elemental character who possesses formidable abilities that enable him to inflict significant damage upon his adversaries at close range while simultaneously providing support for his team. His Pyro-based attacks are incredibly potent, and he can generate Pyro elemental particles with ease.

To construct a triumphant team around Thoma, players must take into account the elemental reactions that his attacks can elicit. Pyro can trigger elemental reactions like Vaporize and Melt when coupled with Hydro and Cryo elements, respectively. As a result, it is critical to include characters who can generate these elements to increase the overall damage output of the team.

Furthermore, it is essential to consider Thoma’s role within the team. As a damage dealer, he must be partnered with support characters who can provide healing or shields. He can also benefit from characters who can boost his attack or grant him additional buffs. To maximize his effectiveness, players must carefully balance these factors and select characters that can complement Thoma’s abilities.

Pyro Burgeon Team

This team composition focuses on Pyro Burgeon reactions, with Thoma acting as the Pyro trigger.

• Main DPS: Ayato
• Sub-DPS: Thoma
• Sub-DPS: Collei or Nahida
• Support: Traveler (Dendro) or Bennett

In this setup, Thoma complements Ayato’s damage output by enabling strong Pyro Burgeon reactions. Collei or Nahida provide additional elemental reactions, while Traveler (Dendro) or Bennett offer support through healing and elemental buffs.

In the Pyro Burgeon Team, Collei or Nahida can offer additional elemental reactions to Thoma’s Pyro triggers, creating even more opportunities for damage. Meanwhile, Traveler (Dendro) or Bennett can provide valuable support by healing the team and boosting their elemental abilities.

Standard Pyro Sub-DPS Team

Thoma serves as the Pyro Sub-DPS in this team, focusing on off-field Pyro damage to enable Vaporize reactions for the Hydro Main-DPS.

• Main DPS: Tartaglia
• Sub-DPS: Thoma
• Support: Kazuha
• Support: Bennett

With this team, Thoma provides Pyro damage for Tartaglia to trigger Vaporize reactions. Kazuha offers crowd control and elemental mastery buffs, while Bennett supports the team with healing and attack boosts.

Standard Pyro Support Team

In this composition, Thoma functions as a Pyro Support, working alongside a core Pyro Main-DPS and Hydro Sub-DPS.

• Main DPS: Hu Tao
• Sub-DPS: Xingqiu
• Support: Thoma
• Support: Kazuha

Thoma provides shields and a useful buff with his C6 unlocked, while Xingqiu offers additional elemental reactions. Kazuha enhances the team’s elemental mastery and provides crowd control.

Pyro Shielder Support Team

Thoma acts as a Pyro Shielder in this Triple Geo team composition, providing off-field Pyro damage and enabling the Crystallize reaction for increased survivability.

• Main DPS: Itto
• Sub-DPS: Albedo
• Support: Gorou
• Support: Thoma

In this setup, Thoma’s shielding ability and off-field Pyro damage create a sturdy foundation for Itto to deal massive Geo damage. Albedo and Gorou further amplify the Geo-focused team’s damage output and provide additional support.

Thoma: Ability Rundown

Thoma’s kit is very powerful when it comes to shielding, and damage. To maximize Thoma’s potential in combat, it’s crucial to learn his various attacks and their specific uses.

Here’s an in-depth explanation of Thoma’s abilities:

Normal Attack: Spear Combo

Thoma’s normal attack consists of a series of up to four consecutive spear strikes. Each strike inflicts damage on the opponents and can be chained together seamlessly, allowing you to keep the pressure on your enemies.

The rapid succession of strikes makes it an effective way to deal sustained damage to individual targets or small groups.

	1	2	3	4	5	6	7	8	9	10	11
1-Hit DMG (%)	44.39	48.01	51.62	56.78	60.4	64.53	70.2	75.88	81.56	87.75	93.95
2-Hit DMG (%)	43.63	47.18	50.73	55.8	59.35	63.41	68.99	74.57	80.15	86.24	92.33
3-Hit DMG (%)	26.79×2	28.97×2	31.15×2	34.27×2	36.45×2	38.94×2	42.36×2	45.79×2	49.22×2	52.95×2	56.69×2

Charged Attack: Stamina-Driven Lunge

By consuming a portion of his stamina, Thoma can perform a charged attack that sends him lunging forward. During the lunge, he deals damage to any opponents in his path, making it an ideal move for closing the gap between you and your enemies or swiftly repositioning during combat.

This attack is particularly useful when dealing with multiple enemies or when you need to catch up to a fleeing target.

Charged Attack
Charged Attack DMG (%)	112.75	121.92	131.1	144.21	153.39	163.88	178.3	192.72	207.14	222.87	238.6
Charged Attack Stamina Cost	25

Plunging Attack: Aerial Impact

Thoma’s plunging attack enables him to leap from mid-air and strike the ground with immense force. As he descends, he damages any opponents along his path, culminating in a powerful area-of-effect (AoE) attack upon impact with the ground.

This maneuver is excellent for targeting clusters of enemies or initiating combat from an elevated position, allowing you to take advantage of the terrain and surprise your foes.

Plunging Attack
Plunge DMG (%)	63.93	69.14	74.34	81.77	86.98	92.92	101.1	109.28	117.46	126.38	135.3

Elemental Skill: Blazing Blessing

Thoma’s Elemental Skill, Blazing Blessing, is a formidable technique that packs a punch in both offense and defense. With a swift vault forward using his polearm, Thoma delivers a fiery flying kick that unleashes a devastating wave of AoE Pyro damage, leaving enemies reeling in its wake. But that’s not all.

Thoma’s Blazing Blessing also conjures up a powerful Blazing Barrier that protects Thoma and imbues him with the power of Pyro.

The Blazing Barrier is a unique shield that absorbs damage based on a percentage of Thoma’s maximum HP, making it an excellent choice for tanky builds. What’s more, it is 250% more effective at absorbing Pyro damage than other types of damage.

And if you’re lucky enough to obtain a new Blazing Barrier while the old one is still active, you’ll enjoy even more damage absorption as the remaining damage absorption stacks and its duration is refreshed. However, do note that the maximum damage absorption is capped at a certain percentage of Thoma’s maximum HP.

Thoma’s Passive Talent 1, Imbricated Armor, enhances Blazing Blessing by boosting the Shield Strength of the active character by 5% for 6 seconds every time they obtain or refresh a Blazing Barrier. And the effect can be triggered once every 0.3 seconds, stacking up to 5 times. But Thoma’s Constellation Effects take things up a notch.

Constellation Effects

At Constellation Level 1, A Comrade’s Duty, Thoma’s Blazing Barrier comes to the aid of his teammates. Whenever a protected character is attacked, the cooldowns of Blazing Blessing and Crimson Ooyoroi are reduced by 3 seconds. But beware, this effect has a 20-second cooldown.

At Constellation Level 3, Fortified Resolve, Thoma’s Blazing Blessing talent level is increased by 3, elevating its maximum level to 15.

Finally, at Constellation Level 6, Burning Heart, all party members’ Normal, Charged, and Plunging Attack damage is increased by 15% for 6 seconds every time a Blazing Barrier is obtained or refreshed.

	1	2	3	4	5	6	7	8	9	10	11	12	13	14
Skill DMG (%)	146.4	157.38	168.36	183	193.98	204.96	219.6	234.24	248.88	263.52	278.16	292.8	311.1	329

Skill CD	15s

Elemental Burst: Ooyoroi

Thoma’s Elemental Burst, Crimson Ooyoroi, showcases his ability to manipulate Pyro energy by spinning his polearm rapidly. As he slices through his enemies, roaring flames erupt from his weapon, dealing significant area-of-effect (AoE) Pyro damage. These flames then form a powerful protective armor called Scorching Ooyoroi around Thoma or the active character.

Scorching Ooyoroi When active, Scorching Ooyoroi enhances the current character’s Normal Attacks, causing them to trigger a secondary effect called Fiery Collapse. Fiery Collapse releases a cone-shaped AoE Pyro damage every 1 second. Additionally, each Fiery Collapse summons a Blazing Barrier that shields the character from damage.

Blazing Barrier Mechanics The Blazing Barrier created during Scorching Ooyoroi works similarly to the one formed by Thoma’s Elemental Skill, Blazing Blessing.

It absorbs 250% more Pyro damage, and when a new Blazing Barrier is obtained, the remaining damage absorption of the existing barrier stacks, and its duration refreshes. The maximum damage absorption capacity of the Blazing Barrier is capped at a certain percentage of Thoma’s maximum HP. If Thoma is defeated, Scorching Ooyoroi’s effects are removed.

Crimson Ooyoroi Interactions Thoma’s Passive Talent 1, Imbricated Armor, and Passive Talent 2, Flaming Assault, both affect the performance of Crimson Ooyoroi. Imbricated Armor increases the Shield Strength by 5% for 6 seconds whenever a Blazing Barrier is obtained or refreshed, stacking up to 5 times. Flaming Assault boosts Fiery Collapse’s damage by 2.2% of Thoma’s maximum HP.

Constellation Effects

Thoma’s constellation levels further enhance his Crimson Ooyoroi:

1. Constellation Level 1 – A Comrade’s Duty: Decreases the cooldown of Thoma’s Blazing Blessing and Crimson Ooyoroi by 3 seconds whenever a character protected by Thoma’s Blazing Barrier is attacked (excluding Thoma). This effect has a 20-second internal cooldown.
2. Constellation Level 2 – A Subordinate’s Skills: Increases Crimson Ooyoroi’s duration by 3 seconds.
3. Constellation Level 4 – Long-Term Planning: Restores 15 Energy to Thoma after using Crimson Ooyoroi.
4. Constellation Level 5 – Raging Wildfire: Enhances Crimson Ooyoroi’s talent level by 3 and raises its maximum level to 15.
5. Constellation Level 6 – Burning Heart: Boosts the damage dealt by all party members’ Normal, Charged, and Plunging Attacks by 15% for 6 seconds when a Blazing Barrier is obtained or refreshed.

Additional Notes

Crimson Ooyoroi does not snapshot Thoma’s stats and will dynamically adjust based on changes in Thoma’s attributes after the ability is cast. Fiery Collapse triggers in the direction of the attack’s impact rather than the character’s facing direction.

It may be triggered by distant Normal Attacks, but Fiery Collapse starts from the player’s position and may not reach the intended target.

Thoma – Passive Talents

Thoma boasts a set of three passive talents that enhance his abilities as a shield support and damage dealer, as well as providing a unique bonus when fishing in Inazuma.

Some talents are available as you ascend the character, while others are unlocked automatically. Here’s a detailed breakdown of Thoma’s passive talents and their effects:

Imbricated Armor – Ascension 1 Talent

Upon obtaining or refreshing a Blazing Barrier, the Shield Strength of your active character is increased by 5% for 6 seconds. This effect can be triggered once every 0.3 seconds and can stack up to 5 times. The Imbricated Armor talent further enhances Thoma’s shielding capabilities, offering better protection for your team.

Flaming Assault – Ascension 4 Talent

This talent increases the damage dealt by Thoma’s Crimson Ooyoroi’s Fiery Collapse by 2.2% of his Max HP. By scaling with his maximum health, Flaming Assault allows Thoma to deal more damage as he grows stronger, making him more effective in battles.

Snap and Swing – Utility Passive

Thoma’s Snap and Swing talent provides a unique bonus when fishing successfully in Inazuma. With Thoma’s help, there’s a 20% chance of scoring a double catch. If an Ornamental Fish is caught, the player will receive an additional Ornamental Fish.

It’s important to note that any bonus fish caught won’t count towards the “Ding Ding Ding!” achievement, nor will they be tracked in the archive.

Thoma does not need to be in the active party for Snap and Swing to take effect. In Co-Op Mode, only players who own Thoma can benefit from this passive talent.

Thoma – Constellations

Similar to other characters in Genshin Impact, Thoma possesses a total of six constellations that provide a combination of damage enhancement and utility-based improvements to his abilities.

Here are the detailed effects of Thoma’s Constellations during combat:

Level 1 Constellation – A Comrade’s Duty

This initial constellation benefits Thoma by reducing the cooldowns of his own Blazing Blessing and Crimson Ooyoroi abilities by 3 seconds when a character protected by Thoma’s Blazing Barrier (excluding Thoma himself) is attacked. This effect can be triggered once every 20 seconds, allowing Thoma to provide more frequent support and protection to his allies.

Level 2 Constellation – A Subordinate’s Skills

With this constellation, Thoma’s Crimson Ooyoroi ability has its duration extended by 3 seconds. This extension allows Thoma to maintain his defenses for a longer period, increasing his overall survivability and the protection he offers to his teammates.

Level 3 Constellation – Fortified Resolve

This constellation boosts the power of Thoma’s Blazing Blessing ability by raising its level by 3. The maximum level cap for this ability is increased to 15, enabling Thoma to provide even greater protection and support to his allies with each use of the skill.

Level 4 Constellation – Long-Term Planning

Upon using Crimson Ooyoroi, Thoma receives a restoration of 15 Energy. This energy boost ensures that Thoma can more frequently activate his Elemental Burst, contributing more consistently to his team’s overall performance.

Level 5 Constellation – Raging Wildfire

Thoma’s Crimson Ooyoroi ability becomes even more effective with this constellation, as it increases its level by 3. With a maximum level cap of 15, this enhancement allows Thoma to further improve his defensive capabilities and contribute more significantly to his team’s success in battle.

Level 6 Constellation – Burning Heart

When a Blazing Barrier is obtained or refreshed, this constellation increases the damage dealt by all party members’ Normal, Charged, and Plunging Attacks by 15% for 6 seconds.

This constellation greatly enhances the damage output of Thoma’s allies, making him an even more valuable member of the team.

Activating each of these constellations requires one of Thoma’s Stella Fortuna. As you unlock more constellations, Thoma’s strength and utility in combat will continue to grow, making him an increasingly powerful force in the world of Genshin Impact.
