Bailu is one of two healer available in Honkai Star Rail right now. Considering that Honkai Star Rail only have 2 healers at the moment, Bailu is the best healer in the game right now. If you are lucky enough to get her from Warp, then I guarantee that your team survivability rate will be high even in auto mode.

Rarity	5 Star
Path	The Abundance
Element	Lightning
Faction	Xianzhou Luofu

Bailu is The High Elder of the Vidyadhara, who is also known as the “Healer Lady” on the Luofu. She uses her unique medical science and the medical treatment that can only be provided by the Vidyadhara dragon race to save lives.

Bailu Build in Honkai: Star Rail

She have appearance of a small child with dragon horn and dragon tail, some people even jokingly said that she is Qiqi of Honkai Star Rail. But luckily she didn’t suffer same fate as Qiqi during early days of Genshin Impact (outclassed by character with lower rarity).

You will met the dragon lady in Xianzhou Luofu main story when she tried to heal some mara struck soldier. Trailblazer will interract and help her a bit in the story. Take a note that I won’t mention skills and traces priority here, because in my opinion IF you are gonna build character and use her a lot, I will assume that you are gonna level them all equally.

Besides regular healing skills, Bailu also have revive mechanics for just in case your teammates died in the middle of fight. Without further delay, here’s all recommendations to build bailu:

Bailu Light Cones

To improve her healing and recovery, here’s all 4 recommended Light Cone to use:

Time Waits for No One: Increases the wearer’s Max HP by 18/21/24/27/30% and Outgoing Healing by 12/14/16/18/20%. When the wearer heals allies, record the amount of Outgoing Healing. When any ally launches an attack, a random attacked enemy takes Additional DMG equal to 36/42/48/54/60% of the recorded Outgoing Healing value. This Additional DMG is of the same Type as the wearer’s, is not affected by other buffs, and can only occur 1 time per turn.
Post-Op Conversation: Increases Energy Regeneration Rate of its wearer by 8/10/12/14/16% and increases Outgoing Healing when they use their Ultimate by 12/15/18/21/24%.
Warmth Shortens Cold Nights: Increases the wearer’s Max HP by 16/20/24/28/32%. When using Basic ATK or Skill, restores all allies’ HP by an amount equal to 2/2.5/3/3.5/4% of their respective Max HP.
Shared Feeling: Increases the wearer’s Outgoing Healing by 10/12.5/15/17.5/20%. When using Skill, regenerates 2/3/3/4/4 Energy for all allies.

Best Relics and Planar Ornaments

For healer character, the only choice is Passerby of Wandering Cloud which obtainable from Cavern of Corrosion: Path of Drifting in Corridor of Fading Echoes, Jarilo-VI.

(2) Increases Outgoing Healing by 10%.
(4) At the beginning of the battle, immediately recovers 1 Skill Point.

Planar Sets: Link and Rope

There’s 2 Planar Ornament that you can use on her. This 2 ornament have it’s own plus depend on what team you are using and what are you gonna use Bailu for, whether it’s purely healing or energy regeneration support as well.
