Genshin Impact’s Thoma is the sweetest cinamon roll you’ll ever meet. He also happens to be a pretty great house husbando, and a decet four-star pyro polearm wielder with a great shield at higher investment. In this Genshin Thoma build we take a look at his skills, constellations, best weapons, and more, so you can give him the respect he deserves after all that hard work he does around the Kamisato household.

Here’s everything in our Genshin Impact Thoma build guide.
What’s the best Genshin Impact Thoma build?
Thoma is a pyro support character capable of shielding his team with his skill and burst, while also setting his enemies ablaze, shredding their defenses. He’s quite situational, but currently has the second strongest shield at max stacks, and offers great stagger resistance. He’s pretty cost-effective, requiring low investment and less resin to build than other characters.
However, he has extremely high energy recharge requirements, his damage and skills don’t scale well, and he’s a pretty niche option for most teams, meaning he can usually be replaced by a stronger unit.
Don’t sleep on Thoma, though. Especially in the current, dendro-heavy meta of Sumeru, he’s finding a firm place among many elemental reaction teams.

What’s the best Genshin Impact Thoma weapon?
Due to Thoma’s desperate need for energy recharge, we recommend equipping him with any weapons that boost that stat. Engulfing Lightning is a great choice for elemental interaction teams, due to it having both energy recharge and elemental mastery, but is more often better used on Genshin Impact’s Raiden or Genshin Impact’s Xiangling.
Alternatively, Favonius Lance is a great choice, helping you meet your energy recharge requirements, but you need a lot of crit rate to trigger its passive reliably. If you’ve got a spare Skyward Spine, this also works to boost his energy recharge, but offers little else.
Outside of the above, the Catch is the best free to play option, but, like Engulfing Lightning, is highly contested by other characters. A good alternative is Kitain Cross Spear, which falls behind in its general buffs, but is far more affordable for a niche character like Thoma.
|Increases attack by 28% of energy recharge over the base 100%. You can gain a maximum bonus of 80% attack. Gain 30% energy recharge for 12 seconds after using an elemental burst
|Crit hits have a 60% chance to generate a small amount of elemental particles, which will regenerate six energy for the character. Can only occur once every 12 seconds
|Increases crit rate by 8% and increases normal attack speed by 12%. Additionally, normal and charged attacks hits on opponents have a 50% chance to trigger a vacuum blade that deals 40% of attack as damage in a small AoE. This effect can occur no more than once every two seconds
|Increases elemental burst damage by 16% and elemental burst critical rate by 6%
|Kitain Cross Spear
|Increases elemental skill damage by 6%. After your elemental skill hits an opponent, your character loses three energy but regenerates three energy every two seconds for the next six seconds. This effect can occur once every ten seconds. Can be triggered even when the equipping character is not on the field
What are the best Genshin Impact Thoma artifacts?
If you plan to use Thoma on a melt or vaporize team, a four piece set of instructor is a good choice, due to its high elemental mastery. However, it’s not without its caveats. Instructor costs him his shield strength, doesn’t offer energy recharge, and the crit rate he requires for Favonius Lance’s passive.
Alternatively, if no one else has a set of Noblesse Oblige on the team, then it’s a good option for Thoma. Just ensure that you only use this if Thoma has enough energy recharge to burst regularly.
A really strong set combines two Tenacity of the Milelith with two Emblem of Severed Fate, providing him with energy recharge and HP% for his shield, though it can cost quite a bit of resin to get this set with all the sub-stats you need.
|Two equipped: elemental mastery +80
Four equipped: increases all party members’ elemental mastery upon triggering an elemental reaction by 120 for eight seconds
|Two equipped: elemental burst damage +20%
Four equipped: increases all party members’ attack by 20% for 12 seconds after using an elemental burst. This effect cannot stack
|Emblem of Severed Fate
|Two equipped: energy recharge increases by 20%
Four equipped: elemental burst damage increases by 25% of Thoma’s energy recharge. A maximum of 75% bonus damage can be obtained in this way
|Tenacity of the Millelith
|Two equipped: HP increases by 20%
Four equipped: when an elemental skill hits an enemy, the attack of nearby party members is increased by 20% and their shield strength is increased by 30% for three seconds. This can be triggered once every 0.5 seconds. It can still be triggered even when Thoma is not on the field
Your priority should be getting Thoma to at least 200-250% energy recharge above anything else.
- Sands: energy recharge
- Goblet: HP%
- Circlet: HP% or crit rate (crit rate is important here if you’re using Favonius Lance)
- Energy recharge
- Crit rate (if using Favonius Lance)
What are Genshin Impact Thoma’s skills?

|Swiftshatter Spear (charged)

|Swiftshatter Spear (plunging)
|Thoma plunges from mid-air to strike the ground, damaging enemies and dealing AoE damage
|Thoma launches forward with his polearm and delivers a flying kick that deals AoE pyro damage, while also summoning a Blazing Barrier. When Thoma casts Blazing Blessing, his elemental skill applies pyro to himself.
Blazing Barrier: pyro damage is absorbed 250% more effectively. When a new Blazing Barrier is obtained, the remaining absorption of an existing barrier stacks, and the duration is refreshed
|Thoma spins his polearm, dealing AoE pyro damage and weaving himself into a Scorching Ooyoroi.
Scorching Ooyoroi: While Scorching Ooyoroi is in effect, the active character’s normal attacks trigger Fiery Collapse, this deals AoE pyro damage and summons a Blazing Barrier. Fiery Collapse can be triggered once every one second. Except for the amount of damage they can absorb, the Blazing Barriers created in this way are identical to those created by Blazing Blessing. If Thoma falls, the effects of Scorching Ooyoroi are cleared
|When you obtain or refresh a Blazing Barrier, your shield strength will increase by 5% for six seconds. You can trigger this once every 0.35 seconds
|Damage dealt by Crimson Ooyoroi’s Fiery Collapse is increased by 2.2% of Thoma’s Max HP
|Snap and Swing
|When you successfully fish in Inazuma, Thoma’s help grants a 20% chance of scoring a double catch
