2026-05-07
Happy anniversary, Trailblazers! After the Version 4.2 update, the limited 5-star characters Firefly, Huohuo, Seele, and the regular 5-star character Welt will receive significant Character buff!
Now, let's take a closer look at the effects of these character buffs.
Firefly
Skill
Fyrefly Type-IV: Deathstar Overload
Firefly will now add Fire Weakness not only to one enemy target, but also to adjacent targets.
Bonus Ability
Module α: Antilag Outburst
Firefly's Break Effect is increased by 25% while in the 【Complete Combustion】 state. Additionally, when she inflicts Weakness Break on a target, 【Complete Combustion】 is delayed by 10%. This effect can be triggered up to 3 times per 【Complete Combustion】 state.
Module β: Autoreactive Armor
When the Break Effect is greater than or equal to 150%/300% (originally 200%/360%) in the 【Complete Combustion】 state, the Toughness Reduction from this attack against a Weakness-Brokenenemy target will be converted into one instance of 100%/150% Super Break DMG (originally 35%/50%).
Eidolon enhancement
Eidolon 2
From Shattered Sky, I Free Fall
The condition to gain an extra turn by defeating an enemy target or inflicting Weakness Break on them has been changed from having a 1-turn cool down to being trigger able once per turn.
This buff significantly enhances Firefly's AoE Break efficiency and damage. Additionally, extending her Ultimate's countdown after inflicting Weakness Break further expands her damage window. However, Skill Point availability remains tight at Eidolon 0.
Huohuo
talent
Possession: Ethereal Metaflow
【Divine Provision】 can now be obtained by using either a Skill or an Ultimate (previously only by using a Skill), and its duration is increased from 2 turns to 3 turns.
At the start of an ally's turn or when an Ultimate is used, its healing effect now restores HP to the user and the ally with the lowest current HP (instead of the user and allies with HP below 50%), and then restores HP to all allies with HP below 50%.
Furthermore, the ability of 【Divine Provision】 to dispel 1 debuff is refreshed immediately upon obtaining the effect, rather than only when a Skill is used.
Bonus Ability
Fearful to Act
When battle starts, the effect is changed from gaining 1 【Divine Provision】 to gaining 2【Divine Provision】 , and Huohuo additionally gains 30 Energy.
The Cursed One
When an Ultimate is used, for ally targets whose Max Energy is 160 or higher, it will additionally increase their ATK by 24%.
This enhancement slightly improves Huohuo's healing and support capabilities. Additionally, the mechanic of restoring 【Divine Provision】through her Ultimate reduces her reliance on frequently using her Skill to maintain the effect, significantly improving her Skill Point generation capability.

skill
Sheathed Blade
Damage dealt is increased from 220% of ATK to 360% of ATK, and the SPD increase's duration is extended from 2 turns to 3 turns.
Additionally, after an ally attacks, if the target's current HP is below 50%, Seele will automatically use her Skill on that target without consuming a Skill Point. This can be triggered once per turn. If there are no valid targets to attack, Seele will attack the single enemy with the lowest HP. This Skill usage does not generate Energy.
Ultimate
Butterfly Flurry
Damage dealt is increased from 425% of ATK to 720% of ATK.

As a launch-era character, this adjustment significantly boosts Seele's DPS, indicating she can perform well even against the new meta. The additional Skill available once per turn further enhances her ability to clear adds. With various buffs extended to 3 turns, they can essentially be considered active for the entire battle duration. After these buffs, this vlaunch-era character has the potential to deliver extraordinary performance in specific scenarios.

The effect is changed from dealing Additional DMG when using the Skill to: When using the Skill or Ultimate and hitting a Slowed enemy target, the CRIT Rate is increased by 30% and the CRIT DMG is increased by 60%.
The most significant change for Welt is his shift from a pure DPS role to a support role with considerable utility, while his own damage output has also been further enhanced. This means Welt can now be integrated into new team compositions as a secondary DPS. If you already have his Eidolons, the capabilities of this standard character will be improved even more substantially.
Conclusion
Compared to the previous round of character adjustments, this set of Character buff is more targeted and bolder. They not only address the original pain points of some older characters but also allow them to remain viable in the new meta. The Character buffs for Seele and Welt, in particular, demonstrate that the developers have not forgotten characters the community may have overlooked. For players eager to bolster their rosters or dive deeper into the refreshed meta, you can top up Honkai: Star Rail with BuffBuff.
