Normal Attack
Performs up to four consecutive spear strikes.
Charged Attack
Consumes a certain amount of Stamina to lunge forward, dealing damage to opponents along the way.
Plunging Attack
Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact.
A beautiful set of Normal Attacks — however, you usually don’t see them too often if you’re playing Thoma’s more popular playstyles such as Shield Support or Burgeon.
This is the main source of damage for Physical Thoma and a significant amount of damage for On-Field Pyro Thoma. Thoma’s recommended NA string for these playstyles is N4D/N4J for Stamina management as well as the stagger provided by his final Normal Attack.
Thoma vaults forward with his polearm and delivers a flame-filled flying kick that deals AoE Pyro DMG, while also summoning a defensive Blazing Barrier.
At the moment of casting, Thoma's Elemental Skill applies Pyro to himself.
The DMG Absorption of the Blazing Barrier scales off Thoma's Max HP.
The Blazing Barrier has the following traits:
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.
His skill applies an initial hit of AoE Pyro DMG that summons a Blazing Barrier, Thoma’s shield. Thoma’s Blazing Barrier lasts for 8 seconds if not refreshed, and absorbs Pyro DMG 250% more effectively. The percentage of Thoma’s HP that contributes to the DMG Absorption of the Blazing Barrier at max stacks is dependent on Thoma’s Skill Talent Level. For more information on how Thoma’s Blazing Barrier works, see the ‘Blazing Barrier: How Thoma’s Shield Works’ section.
Thoma’s Skill cooldown is 15 seconds (12 seconds with C1) and produces 3-4 particles at a 1:1 ratio– 50% chance to get 3 particles and 50% chance to get 4 particles. Additionally, activating his Skill applies Pyro to himself, cleansing all Elements excluding Pyro.
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:
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.
If Thoma falls, the effects of Scorching Ooyoroi will be cleared.
An integral part of Thoma’s kit in every playstyle except Physical, but it comes at a high cost of 80 Energy. Thoma’s Burst has an initial hit of AoE Pyro DMG which creates a Scorching Ooyoroi, a pair of flaming armor plates that spin around the active character for the duration of Thoma’s Burst. The Scorching Ooyoroi is not a shield. Additionally, Thoma does not create a Blazing Barrier upon his Burst initial hit.
The Scorching Ooyoroi will create Fiery Collapses, cones of AoE Pyro DMG in front of the active character when they use Normal Attacks, up to once per second. These NAs don’t need to hit an enemy to proc a Fiery Collapse.
Each Fiery Collapse creates another Blazing Barrier that stacks onto the existing Blazing Barrier. For more information on Thoma’s shielding mechanic, please see the ‘Blazing Barrier: How Thoma’s Shield Works’ section.
The final Fiery Collapse may activate after the visual effect of the Scorching Ooyoroi has disappeared. Here is an example of this—the 15th and final Fiery Collapse comes out after the armor has disappeared.
Thoma’s Burst lasts for 15 seconds at C0 and 18 seconds at C2. His Burst’s cooldown may be reduced from 20 seconds to 17 seconds with C1.
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 0.3 seconds. Max 5 stacks.
A decent Ascension Passive for Shield Support Thoma that allows the on-field party member to gain Shield Strength when protected by a Blazing Barrier. This Shield Strength does not persist after swapping characters so it’s important to stack your shield while your DPS is on-field.
DMG dealt by Crimson Ooyoroi's Fiery Collapse is increased by 2.2% of Thoma's Max HP.
Introduces dual scaling to Thoma’s Fiery Collapses. Generally inconsequential for Shield Support Thoma due to his low multipliers, but does provide a nice damage buff for Hybrid Thoma.
When you fish successfully in Inazuma, Thoma's help grants a 20% chance of scoring a double catch.
If you don’t have The Catch R5—first of all, what are you doing, and second of all, not to worry—Thoma can help you with his Passive Talent! There are some special notes about this Passive:
Any bonus fish from this Passive do not count towards the Ding Ding Ding! Achievement (Catch 100/500/2000 fish successfully).
It will work on Ornamental Fish, meaning if the Passive procs when you fished up an Ornamental Fish, you will get two Ornamental Fish.
Thoma’s Blazing Barrier can be created in two different ways: with his Skill and with the Fiery Collapses produced by his Burst. His Skill will produce a strong Blazing Barrier in one instant; however, in order to strengthen it further, you’ll need to stack it through his Burst. This can be done as follows:
Every time a Fiery Collapse is triggered, you gain a new Blazing Barrier whose DMG Absorption stacks, or combines, with the existing Blazing Barrier. When you stack a new Blazing Barrier, it refreshes the duration of the existing Blazing Barrier, meaning that the shield’s duration will reset to 8 seconds every time you gain a new shield.
His fully stacked shield is 2nd in terms of Max DMG Absorption, only behind Zhongli’s. However, the shield produced by his Skill alone is significantly weaker and falls behind Diona’s.
In order to get the max amount of stacks on Thoma’s Blazing Barrier, you need to use his Skill and proc 10-11 Fiery Collapses depending on your Talent Levels. With his Skill and 6-7 Fiery Collapses, Thoma’s shield becomes better than Diona’s Hold Skill.
Here is an additional explanation from dorketh about how Thoma’s shield works.
TL;DR: Always use your Skill and Burst together, then NA with your DPS to create a strong Blazing Barrier.
