Thoma vs Xinyan

The Burgeon specialist vs. the Physical support hybrid

TL;DR — Quick Pick

Pick Thoma if…

  • In Dendro-Hydro teams as a dedicated Burgeon trigger (EM build)
  • When you need a shield that can refresh and stack durability over time
  • If you need a reliable Pyro battery who doesn't steal field time

Pick Xinyan if…

  • In a Physical DPS team (Eula/Razor) for the shred and bonus damage
  • If you lack any other Pyro characters and need a filler shield
  • At C6, if you are running a Main DPS who uses Charged Attacks
Verdict

Thoma has found a strong niche in Burgeon teams, making him a relevant unit. Xinyan suffers from awkward split-scaling and a shield that breaks too easily, making her difficult to recommend in the current meta.

Shared Team Members

NahidaNahida

With Thoma

Nahida provides the heavy Dendro application needed to create the Dendro cores that Thoma's Burst triggers for Burgeon. Her EM sharing also increases the damage of those Burgeon explosions, making the duo the core of most Thoma-based Dendro teams.

With Xinyan

Nahida enables consistent Burning on enemies, which Xinyan can use to maintain a Pyro aura or trigger specialized reactions. This niche interaction allows Xinyan to benefit from Nahida's EM buffs and provide some utility in Burning-focused compositions.
