Honkai: Star Rail – Topaz build and ascension guide

Unleash the adorable power of Numby with the best Honkai: Star Rail Topaz build and become the IPC’s top-performing employee. Following the Path of The Hunt and dealing Fire DMG, Topaz and Numby are an unconquerable duo when they work together to make their adversaries pay any outstanding debts.

Topaz summons her loyal Warp Trotter Numby at the beginning of the battle thanks to her Talent, Trotter Market?!, after which Numby will have their own slot on the turn order. When it’s Numby’s turn, they’ll attack whichever enemy has the Proof of Debt status, dealing Fire DMG based on Topaz’s ATK. These attacks are counted as Follow-Up Attacks. In addition, Numby’s action is Advanced Forward whenever the target affected by Proof of Debt is hit by an ally’s Follow-Up Attack.

Topaz’s Skill, Difficulty Paying?, inflicts the target with the Proof of Debt status, which increases the Follow-Up Attack DMG they take. Only the most recent enemy targeted with this Skill can have the Proof of Debt status and Topaz will inflict a random enemy with this status in case no one carries it when an allied character’s turn begins. Numby will attack the target immediately when the Skill is used, dealing Fire DMG based on Topaz’s ATK.

Her Ultimate, Turn a Profit!, enables Numby to enter the Windfall Bonanza! state, increasing their damage and CRIT DMG. When Numby is in this state, their action will be Advanced Forward whenever a target afflicted by Proof of Debt is hit by an ally’s Basic Attack, Skill, or Ultimate. Numby exits this state once again after they have made two attacks.

Topaz’s Technique, Explicit Subsidy, allows Numby to search for Trotters and chests in the world and grants the player up to 10,000 Credits per day as additional battle rewards.

Her Eidolon Levels, which can be obtained by getting additional copies of her, provide additional boons: Eidolon 1 inflicts enemies with Proof of Debt that have been attacked with Debtor, which increases the CRIT Rate of Follow-Up Attacks against them — a powerful tool for Follow-Up Attack teams. Eidolon 2 allows Topaz to gain Energy whenever Numby attacks. Eidolon 4 causes Topaz’s next action to be Advanced Forward when Numby acts. Eidolon 6 allows Numby to attack an additional time before leaving Windfall Bonanza! and boosts their Fire RES PEN.

Honkai: Star Rail – Topaz: best Light Cones

Topaz wants as much ATK, CRIT Rate, and CRIT DMG as she can get to help boost Numby’s offensive moves. Her signature Light Cone, Worrisome, Blissful, offers that and more: It increases the wearer’s CRIT Rate and their Follow-Up Attack DMG. Additionally, after the wielder uses a Follow-Up Attack, it inflicts the Tame status on the target, which can stack up to two times. When allies hit an enemy afflicted by Tame, the CRIT DMG they deal is boosted.

Best Light Cones for Topaz in HSR:

• Worrisome, Blissful (5-Star)
• Cruising in the Stellar Sea (5-Star)
• Sleep like the Dead (5-Star)
• Return to Darkness (4-Star)
• Swordplay (4-Star)
• Only Silence Remains (4-Star)

Honkai: Star Rail – Topaz: best Relics

Best Relic Sets for Topaz in HSR:

• The Ashblazing Grand Duke (4) – +20% Follow-Up Attack DMG, +6% ATK each time the wearer uses a Follow-Up Attack to deal damage. This effect lasts three turns and can stack up to eight times. It's removed the next time the wearer uses a Follow-Up Attack.

Honkai: Star Rail – Topaz: best teams

Topaz is a powerful damage dealer in her own right, but shines especially bright as a Sub DPS on Follow-Up Attack teams, where she can maximize the damage output of the Main DPS with her Follow-Up Attack DMG buff.

• Feixiao (Main DPS), Topaz (Sub DPS), Robin (Support), Aventurine (Support)

This powerful Follow-Up Attack team ensures that Feixiao is able to deal the maximum amount of damage through all of her Follow-Up Attacks (thanks to the buffs Topaz and Robin provide) and charge her Ultimate up quickly (thanks to Topaz and Aventurine launching their Follow-Up Attacks).

Dr. Ratio is a robust alternative to Feixiao, while March 7th (Hunt) is another solid Sub DPS that can work alongside Topaz to strengthen the Main DPS. Lingsha is a great alternative in the final slot, being able to launch Follow-Up Attacks as well.

Honkai: Star Rail – Topaz: ascension materials

You can collect Silvermane Badges, Insignia, and Medals from enemies on Jarilo-VI as well as the Simulated Universe.

Silvermane Badges are one of the materials you can easily farm through the Daily Assignments to your characters, making for a steady income of the material. 

Searing Steel Blades are available from the Stagnant Shadow (Great Mine). The best source of Credits are the Golden Calyxes found on many different worlds.
