Topaz comes blazing as the first Fire Hunt character in Honkai: Star Rail. As a debt collector for the Interastral Peace Corporation, she carries out her duties diligently and with empathy, something she's gained from growing up on a dying planet. She's accompanied by Numby, a special Space Trotter capable of devastating enemies with their follow-up attacks. Those follow-up attacks are also the basis of their playstyle, so you have to know how to buff them up as much as possible. Here's what you need to know to build your best Topaz, including the best Light Cones, best Relics, and team comps.

Topaz abilities

The bulk of Topaz and Numby's damage comes from follow-up attacks. That said, many of their abilities support a playstyle that strengthens those attacks and others' follow-up attacks, too.

Topaz and Numby are a team. Think of them as a two-in-one deal, similar to Jing Yuan and the Lightning-Lord. Numby acts on their own turn, and all of their damage counts as a follow-up attack as a result.
