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.
Bailu’s best build includes the five-star Night of Fright light cone which buffs her energy regeneration rate and healing output, a combination of two-piece Passerby of Wandering Cloud with two pieces of Longevous Disciple or Messenger Traversing Hackerspace, and a two-piece set of Fleet of the Ageless. All of her healing scales off her max HP, so double down on that stat to succeed.
How do I use Bailu?
Like most healers, you’re not running Bailu in your team for her basic attack. Make sure you save your skill points to use her skill each turn, and treat her ultimate partially as an emergency healing button but also as a shield thanks to its invigorate effect mitigating incoming damage for two turns.
What are the best light cones for Bailu?
Night of Fright is the current best-in-slot light cone for all healers, including Bailu. It buffs her energy regeneration rate so you can use her ultimate more often while providing passive healing to allies and a handy attack boost. Sadly, as Honkai Star Rail’s Huohuo‘s signature light cone, it’s only available on her event light cone banner.
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. Though more accessible than Night of Fright, this five-star light cone is obtained through gacha or by paying the expensive price tag in the shop, so it still requires a lot of work to get.
Honkai Star Rail Natasha‘s debut light cone, Post-Op Conversation is a great four-star alternative for Bailu as it buffs her energy regeneration for a faster ultimate and then buffs her ultimate’s outgoing healing. Perfect Timing is also a particularly good choice if you’re also running the Broken Keel planar ornament set, which we discuss more below.
| Light cone | Effect | How to obtain |
| Night of Fright | Increases Bailu’s energy regeneration rate by 12%. When any ally uses their ultimate, Bailu restores HP for the ally currently with the lowest HP percentage by an amount equal to 10% of the healed ally’s max HP. When Bailu provides healing for an ally, increases the healed ally’s attack by 2.4%. This effect can stack up to five times and lasts for two turns | Limited light cone banner |
| 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 |
| Post-Op Conversation | Increases Bailu’s energy regeneration rate by 8% and increases outgoing healing when she uses her ultimate by 12% | Gacha |
| Perfect Timing | Increases Bailu’s effect resistance by 16% and increases outgoing healing by an amount equal to 33% of her effect resistance. You can increase her outgoing healing in this way up to
