How to Use Thoma

Elemental Skill Shields Character

Elemental Skill: Blazing Blessing

Thoma's Elemental Skill, Blazing Blessing, deals AoE Pyro DMG to enemies while providing a shield. Thoma's shield is unique as its DMG Absorption can stack based on the remaining Absorption of the previous barrier.

In addition, Thoma will apply Pyro to himself, cleansing certain deterimental effects on him.

Elemental Burst Provides Off-Field Pyro DMG

Elemental Burst: Crimson Ooyoroi

Thoma's Elemental Burst, Crimson Ooyoroi, also deals AoE Pyro DMG to enemies while also surrounding the party with a Scorching Ooyoroi buff.

What is Scorching Ooyoroi?

Scorching Ooyoroi functions similarly as Xingqiu's Rainswords as it can deal Pyro DMG even if Thoma isn't on the field. It can also provide Blazing Barriers when using Normal Attacks once every 1s.

Refreshes Existing Barrier

A Blazing Barrier has a duration of 8 sec, and it refreshes every time your active character uses your normal attacks! The shield also stacks, which means that for every Scorching Ooyoroi proc, you refresh both duration and shield effectivity!

Can Catch Twice the Amount of Fish

Passive Talent: Snap and Swing

After acquiring Thoma, he provides you a 20% chance to double the amount of fish caught in Inazuma, making it effective in collecting more fish than usual.

Thoma does not have to be in the party for his passive to take effect.

Thoma Talents (Skills)

Normal Attack: Swiftshatter Spear

Talent Description
Performs up to four consecutive spear strikes. Charge Attack Consumes a certain amount of Stamina to lunge forward, dealing damage to opponents along the way. Plunge Attack: Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.

Blazing Blessing

Talent Description

Thoma vaults forward with his polearm and delivers a flame-filled flying kick that deals AoE Pyro DMG, while also summoning a Blazing Barrier. At the moment of casting, Thoma's Elemental Skill applies Pyro to himself. The DMG Absorption of the Blazing Barrier scales off of Thoma's Max HP. Blazing Barrier ・Absorbs Pyro DMG 250% more effectively. ・When a new Blazing Barrier is obtained, the remaining DMG Absorption of an existing Blazing Barrier will stack and its duration will be refreshed. The maximum DMG Absorption of the Blazing Barrier will not exceed a certain percentage of Thoma's Max HP. Flavor Text: As a guest from afar, only the most burning passion would allow one to master the pure and precise spear arts of Inazuma. Thoma's mastery, indeed, is not limited to being the ''swiftest-studying student'' or ''a master of the spear,'' but he has imbued his will to protect others and fend off foes into his art as well.

Crimson Ooyoroi

Talent Description

Thoma spins his polearm, slicing at his foes with roaring flames that deal AoE Pyro DMG and weave themselves into a Scorching Ooyoroi. Scorching Ooyoroi While Scorching Ooyoroi is in effect, the active character's Normal Attacks will trigger Fiery Collapse, dealing AoE Pyro DMG and summoning a Blazing Barrier. Fiery Collapse can be triggered once every 1s. Except for the amount of DMG they can absorb, the Blazing Barriers created in this way are identical to those created by Thoma's Elemental Skill, Blazing Blessing. If Thoma falls, the effects of Scorching Ooyoroi will be cleared. Flavor Text: ''I will not forget my initial promise. Let this burning flame protect those I cherish, and may it never be extinguished.''

Imbricated Armor

Talent Description
When your current active character obtains or refreshes a Blazing Barrier, this character's Shield Strength will increase by 5% for 6s. This effect can be triggered once every 0.35 seconds. Max 5 stacks.

Flaming Assault

Talent Description
DMG dealt by Crimson Ooyoroi's Fiery Collapse is increased by 2.2% of Thoma's Max HP.

Snap and Swing

Talent Description
When you fish successfully in Inazuma, Thoma's help grants a 20% chance of scoring a double catch.

Thoughts About Thoma

Character	In-Game Thoughts
Ayaka	Thoma is a dear friend. He always lifts my spirits with his sunny disposition. In a sense, I think of him as another brother, and as a full member of the Kamisato Clan.
Ayato	There is no doubt in my mind about Thoma's loyalty to the Kamisato Clan. A long time ago, partly to see where he stood, I advised him that he would be better off leaving if he didn't want to get drawn into the never-ending disputes that plague public life. Still, he chose to stay, and in all the time he's been with us, he's spared me much worry. There are very few people I trust completely these days, but Thoma is one of them.
Itto	Some of the boys have been telling me that he was the star of the show at the Vision Hunt Ceremony. I'm like — are you kidding me??? How come he gets his own special ceremony!? Was the hundredth Vision supposed to be, like, stronger than the other ninety-nine, or something? Pff, nah, it can't have been that, 'cause, uh, hello! They would've chosen me if that's what they were going for.
Raiden	I can’t deny that I am somewhat culpable in the events that lead to him being almost stripped of his vision, but I rather think the Shogun should be the one to extend a formal apology to him… Okay, fine. I’ll give it some thought...
Sara	The Tenryou Commission’s estate is very large. It would serve us well to have a fine housekeeper like Thoma who could keep all the numerous and disparate household affairs in order. If he ever tires of working for the Kamisato Clan, I would very much like for him to come to us… though I doubt that day will ever come.
Sayu	He's got a Vision, and yet for some reason he pesters me about learning ninjutsu every time I run into him. I don't know what his deal is. It's not like I'd have the time to teach him anyway, I barely get enough sleep as it is.
Yoimiya	He's quite the talker and has reasons behind every word that he says. Sometimes, it might seem like there's no connection, but as he goes on, everything will eventually dovetail nicely towards a single purpose. It's... quite different from how I do things. I ask him for help whenever I encounter a matter I can't settle.

Thoma's Thoughts About Others

Character	In-Game Thoughts
Ayaka	About Ayaka Milady is in all respects a well-rounded person: erudite, compassionate, well-mannered, and elegant... The one thing she could do better is to speak her mind more. In fact, watch out for this the next time you're talking to her — sometimes, she looks like she's about to say something, but then she holds back. If that happens, keep asking her opinion, see if you can encourage her to open up a little.
Ayato	About Ayato As head of the Kamisato Clan, he's in a tough position. With all the political upheaval, he has to contend with public disquiet on one hand and a bunch of self-serving, degenerate public officials on the other. It's best not to dwell on it. All I can do is make sure to look out for him when he's at home.
Beidou	About Beidou The captain of The Crux — a formidable woman indeed. She once promised to take me out onto the open ocean to get a look at the thunderstorm that seals off Inazuma from the outside world. It's a shame that to this day, I've never had the chance to take her up on the offer...
Eula	About Eula You've had a run-in with Eula Lawrence before, huh? All I know is that their whole family are about the worst-tempered people you could ever meet. You're better off steering clear of them if you can help it. Ah, now I'm in a Mondstadt mood again... The memories.
Heizou	About Heizou Ho, that guy is a detective for the Tenryou Commission. He seems to have his own way of doing things — not the easiest person to get along with. Also... Any situation that involves a detective is probably not one that's going to end well. I think I'll keep on giving him a wide berth.
Itto	About Itto Hmm... Word on the street is that he's quite a character — apparently, he even has youkai heritage. Have you met him? If you two are close, maybe you could introduce me sometime. It's good to make friends from all walks of life... youkai included!
Jean	About Jean Oh, so Jean from the Gunnhildr Clan is the Master of the Knights of Favonius now? She definitely deserves it, she's known all over for her impeccable conduct... Oh, just the ''Acting'' Grand Master? Haha, well, someone of her standing won't care about titles.
Raiden	About Raiden Comparison: In my homeland of Mondstadt, almost everyone has great reverence for the Anemo Archon, Barbatos. But people in Inazuma feel a little differently toward the Shogun. How can I put this... They fell love, respect, gratitude... but also fear. The Unknown: Honestly, I don't harbor any resentment toward the Shogun. Yes, she almost took my Vision away, but ultimately that's just because of her unique perspective. Everyone has their own perspective, there's nothing strange about that. The only thing I don't understand is her goal in doing so. What does she imagine eternity really look like for Inazuma? And why is sacrificing her people's aspirations so necessary to achieve it? I can neither understand nor agree with her approach.
Sara	About Sara The Tenryou Commission General... Mm... Make sure to be extra careful if you have any dealings with her. She has a lot of power in her hands, and she's not very open to persuasion. Smiling and batting your eyelids certainly won't get you anywhere with her.
Sayu	About Sayu Ah Sayu, stubborn Sayu. I've asked her countless times to teach me ninjutsu, but she always refuses. She even goes out of her way to avoid me now... I'm just a student looking for a teacher, am I really that out of line?
Yae Miko	About Yae Miko Lady Miko? Wh—What about her? 'sigh' Every time Miss Kamisato sends me out to deliver messages, my least-favorite destination is Grand Narukami Shrine... Oh! N—Not because Lady Miko scares the bejeebers out of me, it's, uh... respect. Yes! She strikes respect deep into my heary, ahahahaha...
Yoimiya	About Yoimiya Of Naganohara Fireworks fame? She's so easy to get along with. Super straightforward, just says whatever she thinks. Oh, and Naganohara fireworks are just incredible, you should take every chance you get to see them in action. Ah, on that note — here, have a coupon!
