Crimson Moon's Semblance is the closest fit on the game's own numbers: Thoma's kit multiplies HP, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Staff of Homa, Rightful Reward and Vortex Vanquisher come next. No playtested ranking has been imported for Thoma, so this is arithmetic over the kit data rather than a damage measurement.
Run Crimson Witch of Flames on Thoma, with Vourukasha's Glow and Tenacity of the Millelith behind it. Main stats are HP% sands, HP% goblet, HP% circlet. Roll substats in the order Energy Recharge > HP% > CRIT Rate > CRIT DMG.
Talent priority is Elemental Burst > Elemental Skill > Normal Attack. The Elemental Burst costs 80 energy, which is what an Energy Recharge target has to clear.
The strongest team is Hu Tao, Xingqiu, Kaedehara Kazuha and Thoma, built around Thoma: Pyro · Vaporize.
Thoma's abilities multiply HP. That is read from the scaling rows on the Elemental Skill and Burst, not from the ability description, so it reflects what the game actually multiplies rather than what the text mentions.
Crimson Moon's Semblance is the closest fit on the data: it is a 5-star polearm with CRIT Rate as its ascension stat, and its passive acts on HP. Rightful Reward is the best 4-star alternative.
Crimson Witch of Flames. Its 2-piece bonus is: Pyro DMG Bonus +15% Its 4-piece bonus is: Increases Overloaded, Burning, and Burgeon DMG by 40%. Increases Vaporize and Melt DMG by 15%. Using Elemental Skill increases the 2-Piece Set Bonus by 50% of its starting value for 10s. Max 3 stacks.
