Now, here are all the important details you need on Honkai Star Rail’s Bailu.
What’s the best Honkai Star Rail Bailu build?
Bailu is a five-star support unit with the power of lightning. She fills the role of main healer perfectly thanks to the high outgoing healing capacity from her skill, ultimate, and passive talent.
Although her healing output is high, it can be a little unreliable due to her skill’s random targeting. Additionally, she’s the only support unit in Honkai Star Rail so far without the ability to remove debuffs. For more consistent healing and debuff control we recommend running Bailu alongside Honkai Star Rail’s Luocha.
What are the best light cones for Honkai Star Rail’s Bailu?
Time Waits for No One is a five-star light cone that is specifically built for Bailu’s kit, increasing her HP and outgoing healing abilities and buffing her attacks. As this five-star light cone is obtained through gacha, you could use any other Abundance path light cone that you have access to.
|Light cone||Effect||How to obtain|
|Time Waits for No One||Increases Bailu’s max HP by 12% and outgoing healing by 12%. When she heals allies, it records the amount of outgoing healing. When any ally launches an attack, a random attacked enemy takes additional damage equal to 50% of the recorded outgoing healing value. This additional damage is of the same type as Bailu’s, is not affected by other buffs, and can only occur once per turn||Gacha, Starlight Exchange shop|
|Warm Nights Won’t Last||Increases Bailu’s max HP by 20%. When she uses her basic attack or skill, Bailu restores all allies HP by 2% of their respictive max HP||Gacha|
|Cornucopia||When Bailu uses her skill or ultimate, her outgoing healing increases by 12%||Gacha, treasure chests, quest rewards|
What are the best relics for Honkai Star Rail’s Bailu?
We recommend equipping Bailu with Passerby of Wandering Cloud to boost healing output and HP. It can be difficult to get a full set of Passerby of Wandering Cloud with your desired sub-stats, so you can mix and match with Musketeer of Wild Wheat while you’re building her.
Bailu’s best Simulated Universe relic set is Fleet of the Ageless as it further increases her max HP and therefore her healing output.
|Relic set||Effect||Obtained from|
|Passerby of Wandering Cloud||Two pieces equipped: increases Bailu’s outgoing healing by 10%
Four pieces equipped: immediately recover one skill point at the beginning of battle
|Cavern of Corrosion: Path of Drifting in Jarilo-VI’s Corridor of Fading Echoes|
|Fleet of the Ageless||Two pieces equipped: increases Bailu’s max HP by 12%. When her speed reaches 120 or higher, all allies’ attack increases by 8%||Immersion Reward devices in World 3 of the Simulated Universe|
|Musketeer of Wild Wheat||Two pieces equipped: increases Bailu’s attack by 10%
Four pieces equipped: increases Bailu’s speed by 6% and her basic attack damage by 10%
|Cavern of Corrosion: Path of Drifting in Jarilo-VI’s Corridor of Fading Echoes|
