Blazing Blessing

Blazing Blessing

Elemental Skill

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 Absoprtion of the Blazing Barrier will not exceed a certain percentage of Thoma's Max HP.

Crimson Ooyoroi

Crimson Ooyoroi

Elemental Burst

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 Absoprtion 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.
