Honkai Star Rail Best Topaz & Numby Build – Light Cones, Relics, & more!

Topaz & Numby make up Honkai: Star Rail's first five-star two-in-one unit (unless you count Clara, though Svarog doesn't run around the overworld). They are of the Fire Element and follow the Path of The Hunt, with a unique kit focusing on follow-up attacks.

While Numby acts independently, its position in the action order can be manipulated with the help of Topaz's skills and her teammates' follow-up attacks. If you managed to pull for Topaz & Numby, here are my recommendations on their best Light Cones, Relics, Planar Ornaments, and teammates.

Best Light Cones for Topaz & Numby in Honkai Star Rail

Below are all the best Light Cones for Topaz & Numby in Honkai: Star Rail:

• Worrisome, Blissful (best-in-slot 5*) - Topaz & Numby's signature Light Cone and their best-in-slot five-star option. It offers a DMG and CRIT Rate boost for follow-up attacks and applies a debuff on enemies, which forces them to receive extra CRIT DMG when hit by allies.
• Cruising in the Stellar Sea (free 5*) - A free-to-play five-star option purchasable from Herta's Store. It offers a large CRIT Rate increase and significantly increases ATK after defeating an enemy. If you have multiple good Light Cones to choose from, consider the conditional ATK increase before choosing Cruising in the Stellar Sea.
• Swordplay (best 4*) - Increases DMG every time Topaz & Numby hit a target, which you can maximize due to their follow-up attack mechanic.

Best Relic Sets and Planar Ornaments for Topaz & Numby in Honkai Star Rail

Without a Relic Set that is tailor-fit for Topaz & Numby's kit, they're better off with two-piece combos of the following:

• Two-piece Firesmith of Lava-Forging (+10% Fire DMG)
• Two-piece Musketeer of Wild Wheat (+12% ATK)
• Only if more SPD needed: two-piece Messenger Traversing Hackerspace (+6% SPD)

Meanwhile, for Planar Ornaments, I recommend using either of these sets:

• Inert Salsotto (best-in-slot) - increases CRIT Rate and further increases Ultimate and follow-up attack DMG when the wearer's CRIT Rate is 50% or above. It's a no-brainer option that complements Topaz & Numby's follow-up attack-dependent kit.
• Space Sealing Station - increases ATK and further increases ATK when the wearer's SPD is 120 or higher.

Which stats should you boost on Topaz & Numby?

Topaz & Numby are DMG dealers, so they're best paired with the following DPS-oriented stats:

• Body: CRIT DMG or CRIT Rate
• Feet: SPD
• Rope: ATK
• Sphere: Fire DMG

For substats, focus on ATK, CRIT Rate, CRIT DMG, and SPD. Topaz & Numby's recommended SPD breakpoint is 134. You can swap out the shoes for ATK if you can meet this limit through substats.

Best Topaz & Numby Team Comps in Honkai Star Rail

Topaz & Numby offer a unique kit focused on dealing follow-up attacks. Some great teammate options for them include, but are not limited to:

• Follow-up attacker: Topaz & Numby help their teammates deal more follow-up attacks, and having more follow-up attacks will also help Advance Forward Numby. Because of this quirk, I highly recommend having teammates who deal follow-up attacks, such as Clara and Himeko.
• Abundance support: You can opt to include a healer for better survivability.
• Preservation support: You can add a shielder for better survivability, with a focus on units like Fu Xuan who do more than just shield, and March 7th who does follow-up attacks.
• Buffer: Opt for ATK or Advanced Forward buffers like Asta, Tingyun, Yukong, and Bronya.
