Strongest Topaz and Numby Build in Honaki: Star Rail

Topaz and Numby are a Fire Hunt pairing that focuses on dealing large amounts of damage while supporting Follow-up characters in their various endeavors. This is done primarily through their debuff Proof of Debt, which increases the damage the marked target suffers from Follow-up attacks by 50%. This debuff is applied by using Topaz and Numby’s skill Difficulty Paying? on a target. As you might suspect, this is a massive boost to any characters that make use of Follow-up attacks, making Topaz and Numby a staple character in these comps.

Outside the debuff, Topaz and Numby deal considerable damage (though not as high as some other carry characters) on their own, making them a valuable addition to any team so long as she can provide her support simultaneously. That said, Topaz and Numby make a fantastic addition to any account looking to capitalize on Follow-up attacks.

Best Relics for Topaz and Numby

Topaz and Numby are unique even among Follow-up characters because all of their attacks are considered Follow-up attacks through the gracious assistance of their Overdraft trace. This means that they can make use of the follow-up-centric relic set, The Ashblazing Grand Duke. This set can be farmed from the Path of Darkness, Cavern of Corrosion.

Both the two-piece and the four-piece of this boost the power of Follow-up attacks, thus making it the absolute best relic set you can equip on Topaz and Numby. Incidentally, Topaz and Numby are also the best characters to make use of the four-piece bonus, because it provides a stacking damage boost every time a singular Follow-up attack deals damage. When Numby launches its follow-up attack, it hits the target several times, allowing for the attack to stack this buff to max after a single activation.

Alternatively, you can also make use of any two set bonuses that provide an increase to ATK%, as ATK is always a good stat to have in excess for a Hunt character. Still, I highly recommend farming out the Ashblazing Grand Duke set as soon as possible.

Best Team Comp for Topaz and Numby

The best team comp for Topaz and Numby capitalizes on making use of Proof of Debt while simultaneously allowing Numby to attack more often. Numby moves up the turn order when a Follow-up attack is launched and hits the target affected by Proof of Debt. This includes allies as well. As such, Dr. Ratio, Ruan Mei, and Fu Xuan are Topaz and Numby’s best team comp. With the introduction of Aventurine, you can replace Fu Xuan to enable even more follow-up attacks to occur.

Dr. Ratio’s Follow-up attacks are extremely potent when paired with the damage boost provided by Proof of Debt. Since these Follow-up attacks are hitting the target affected by Proof of Debt, Numby gets to attack more often. Dr. Ratio’s ultimate allows him to perform Follow-up attacks when the target he uses it on gets hit by any other attack. This unique synergy between the two often allows for extreme damage outside of the standard turn order, as both Topaz and Numby often proc(activate) their respective Follow-up attacks off each other.

Ruan Mei provides a massive damage boost to your entire team, something other Harmony characters cannot do, effectively boosting the potency of both Topaz and Numby equally.

Fu Xuan is the most replaceable, as her entire purpose is to provide protection to your whole team. Even so, this team comp, when properly built, will allow you to crush most of Honkai: Star Rail’s difficult content.

Should you get Topaz and Numby’s Lightcone in Honkai: Star Rail?

This is often the question you may ask when a new character is about to be released in Honkai: Star Rail. In the case of Topaz and Numby, I do recommend getting their Lightcone: Worrisome, Blissful if you can. It gives Topaz and Numby a significant damage boost due to its effects, but more importantly, it allows them to further support their team via the Tame debuff.

When the wearer of this Lightcone attacks with a Follow-up attack, they will apply Tame to the target. Tame stacks up twice, and each stack gives the entire team 12% CRIT DMG when they attack the affected target. With the team comp, I mentioned above, this is a large boost in damage as well. However, due to its universal application, this Lightscone allows Topaz and Numby to support teams outside their ideal comps moderately. You only need one copy of Worrisome, Blissful for it to function, but additional copies increase the CRIT DMG gained from each stack of Tame.

Best Eidolons for Topaz and Numby in Honkai: Star Rail

In terms of Eidolons for Topaz and Numby, all of them outside of the three and five provide significant value to them as a character. If you’re a low-spender looking to get the most bang for your buck, Eidolon One (E1): Future Market is the best place to stop. Here are all of their Eidolons so you can understand exactly what they do.

  • Future Market (E1) – Enemies affected by Proof of Debt will also receive the Debtor debuff, making them take 25% more CRIT DMG from Follow-up attacks. Stacks up twice.
  • Bona Fide Acquisition (E2) – When Numby attacks, Topaz herself gains 5 Energy. This allows for more up-time on her Ultimate: Turn a Profit!
  • Seize the Big and Free the Small (E3) – Provides a damage boost to Skill and Basic Attacks
  • Agile Operation (E4) – When Numby attacks, Topaz is Advanced Forward in the turn order by 20%. This means that Topaz will get to attack more often, meaning more Follow-up attacks. Important.
  • Inflationary Demand (E5) – Boosts the potency of their Ultimate ability.
  • Incentive Mechanism (E6) – When the Ultimate is activated, Numby gains an additional enhanced attack (up from two) and the enhanced attack gets 10% Fire Resistance Penetration (Fire RES PEN).

Topaz and Numby’s E1, E2, E4, and E6 are all high-impact Eidoleons that dramatically improve the power of their kit. While they may read as simplistic, the synergy between these additional effects and the base kit makes these Eidolons more potent than you’d expect.
