The Kamisato Clan’s Housekeeper, Thoma, is a breath of fresh air in the Genshin pool of male characters who all look like they can’t tell a broom apart from a sword. He knows how to cook, clean, sew, and fight; what else can’t he do? Travelers first saw a glimpse of the 4-star Pyro character during the Inazuma arc, and many couldn’t wait to get him on their team.

Are you planning to pull for this polearm 4-star character or skip to save gems for the upcoming banners? If you did already pull or are currently still wishing for Thoma, continue reading to discover the breakdown of his talents, playstyles, weapons, and artifacts.

A Summary Of Thoma’s Kit

Thoma, Titled “Protector From Afar”, is a 4-star Pyro polearm user from Mondstadt. His kit revolves around his capabilities as a Shielder/Pyro Applier for your Burgeon teams.

Thoma‘s Elemental Skill and Burst are the main focus of his build. A supportive Thoma build would equip him with the Noblesse Oblige artifact set, with his preferred weapon for such a build being the Favonius Lance.
A Burgeonreaction-based build would equip him with the Flower of Paradise Lost artifact set and the Kitain Cross Spear polearm.

Thoma’s Elemental Skill and Burst

One way to play Thoma is as a Pyro shielder/support. His Elemental Skill and Burst create a translucent red shield around the active character that blocks incoming Pyro DMG and inflicts Pyro DMG on enemies.

Blazing Blessing (Thoma’s Elemental Skill) is a shield that scales off of Thoma’s max HP. The barrier is reinforced and stacks whenever Thoma gets hit.

On the other hand, Thoma’s Elemental Burst Crimson Ooyoroi deals AoE Pyro DMG and summons another shield similar to AoE Pyro DMG similar to Xingqiu’s Rainswords.

Typically, players can invest into HP and Energy Recharge pieces to build Thoma as a Pyro support/shielder.

His Crimson Ooyori has an 80 Energy Cost and lasts 15s, just like his Elemental Skill.

Pause…

A brief note is necessary here.. C0 Thomais a fantastic unit. Please do not feel forced to roll for a character’s constellations. They are nice to own and can boost a character’s effectiveness, but they aren’t worth spending real-world currency on unless you have a large reserve of expendable income. 

However, if you do end up getting more constellations, congratulations! Let us get you familiar with Thoma‘s Stella Fortuna.

Thoma’s Constellations

ConstellationDescription
Constellation 1: A Comrade’s DutyWhen a character protected by Thoma’s own Blazing Barrier (Thoma excluded) is attacked, Thoma’s own Blazing Blessing CD is decreased by 3s, while his own Crimson Ooyoroi‘s CD is decreased by 3s.
This effect can be triggered once every 20s.
Constellation 2: A Subordinate’s SkillsCrimson Ooyoroi‘s duration is increased by 3s.
Constellations 3 and 5:
Fortified Resolve and Raging Wildfire

Fortified (C3) increases the talent levels of Thoma‘s Elemental Skill, Blazing Blessing, by 3.

Raging Wildfire (C5) increases the talent levels of Thoma‘s Elemental Burst, Crimson Ooyoroi, by 3.

The maximum upgrade level for both of these abilities is now 15.

Constellation 4: Long-Term Planning
After using Crimson Ooyoroi, 15 Energy will be restored to Thoma.
Constellation 6: Burning Heart
When a Blazing Barrier is obtained or refreshed, the DMG dealt by all party members’ Normal, Charged, and Plunging Attacks is increased by 15% for 6s.
