V2.6 Changes & Patch Notes
Many players are curious to know what is going to change in V2.6 for Firefly Honkai Star Rail. Here is a brief overview of what changes you can expect in this version. Keep in mind that the core kit of this character will remain the same because of the Firefly build.
However, some refinements will be made in this character to make it more appealing, powerful, and aesthetics.
The news has confirmed that the recommended trace order has been updated to enhance her ability from Ultimate first, then Talent, and then Skill. It seems like the trace pattern will look like Ultimate > Talent > Skill.
Instead of Firefly trace updates, the speed breakpoints have been clarified. For example, achieving 150 SPD outside of her Ultimate buff is a baseline goal to guarantee a strong turn in Firefly Complete Combustion state.
Many reports have also confirmed the addition of more Firefly F2P light cones in V2.6. These new cones have been documented along with Firefly best light cones that will remain same in this update too.
How Do the Changes Affect Builds & Team Choices?
It is an authentic question, and every player has to get an answer to this question. The reason is that they should be familiar with the effect of these changes on the team builds and team choices. Let us share brief information about the prominent effects for your understanding.
● Trace Priority: As mentioned earlier, Ultimate has not got more emphasis; you need to choose resource materials accordingly.
● Speed Target Focus: With a clear speed benchmark, every player is focused on getting 150 SPD before buffs. It helps make her more accessible and impactful in HSR.
● Team Synergy: As Firefly’s burst window is strong, you need to build around supports that can enhance Weakness Break. It will help her sustain through the burst phase and help you in the gameplay.
Stats, Traces & Priority
When you are looking to get the Firefly's best build, you can’t just start the process. You must be familiar with her stat priorities and trace upgrades. Since she is a break-focused Destruction DPS, her damage scales different from other DPS units.
In the following section, we have shared a brief overview of stat priorities and trace priorities. You must consider keeping them in your mind while building Firefly Honkai Star Rail.
Stat Priorities
Let us share a quick table that summarizes the most recommended main and substates for Firefly builds. You should focus on these stat priorities and follow them for better outcomes.
| Slot | Main Stat | Recommended Substates |
| Body | CRIT Rate / CRIT DMG | Break Effect > CRIT > ATK% > SPD |
| Feet | Speed / ATK% | SPD until ~150 > CRIT > ATK% |
| Planar Sphere | Fire DMG Boost / Break Effect | CRIT > Break Effect > ATK% |
| Link Rope | Break Effect | Break Effect > ATK% > Energy Regen |
Break Effect is Firefly’s key stat because her kit multiplies Break damage during Complete Combustion. However, CRIT Rate and CRIT DMG still matter, especially when you want consistent burst numbers.
For better outcomes, keep your speed around 150 to 160 SPD before buffs. If you try to get more, it may cost too many substates.
Trace (Ascension/Traces) Priority
Firefly trace makes her more powerful and strengthens her burst phase. As her kit revolves around the Ultimate state, you should follow the right approach when upgrading. Here is the best order that you can follow in this regard.
Major Trace Priority
| Priority | Trace | Reason |
| 1 | Ultimate – Complete Combustion | Increases Break damage and unlocks her main DPS window. |
| 2 | Talent – Magma Will | Boosts Break scaling and provides self-buff synergy. |
| 3 | Skill – Deflagration Crash | Adds moderate damage and utility outside Ultimate. |
| 4 | Basic Attack | Lowest return; level last. |
Minor Trace Notes
● You need to unlock Break Effect % and Fire DMG % nodes early.
● HP percentage nodes are useful for survivability during Skill usage since she consumes HP outside of Ultimate.
● Energy Regen Rate minor traces are helpful if you struggle to cycle her Ultimate quickly.
Quick Tip: In early-mid game, focus on leveling her Ultimate and Talent to at least level 8 before worrying about the rest. It will help you improve your gaming experience and get maximum power from Firefly Honkai Star Rail.
