The buffer-shielder vs. the persistent Pyro shield applier.
Pick Nicole if…
Pick Thoma if…
Nicole is strictly the better support if her Hexerei ATK buff and Celestial Gift DMG bonus are active — she provides protection AND meaningful offensive contribution that Thoma simply can't match. Thoma wins in teams that specifically need persistent off-field Pyro application (Burgeon, Burning) or when his on-hit shield refresh synergises better with the active character's kit. As a budget alternative, Thoma is a perfectly solid pick; but if you have Nicole, she upgrades every team she enters.
Nicole
Thoma
With Nicole
Nicole's shield keeps Hu Tao in the low-HP zone safely, and the Celestial Gift DMG% buff directly boosts her Pyro-infused attacks. Nicole's lack of off-field Pyro is irrelevant since Hu Tao applies her own.
With Thoma
Thoma's stacking shield absorbs hits while Hu Tao stays at low HP for her passive. His off-field Pyro application can occasionally interfere with Vaporize if timed poorly — requires careful rotation management.
With Nicole
Kazuha swirls Pyro from Nicole's shield application and spreads the Celestial Gift bonus. Together they form a strong shielder + VV enabler core for any Pyro carry.
With Thoma
Kazuha swirls Thoma's off-field Pyro hits, enabling consistent Pyro-Swirl for VV shred. Thoma + Kazuha is a common core in Pyro reaction teams where off-field Pyro application is needed.
