What is the best Bailu build?

The best Bailu build is:

  • Light Cone – Time Waits for No One
  • Relics – Passerby of Wandering Cloud
  • Planar Ornaments – Fleet of the Ageless
  • Eidolons – Level 2: Pot of Slumbering Dragon
  • Team comp – Bailu, Serval, Bronya, Pela

The best Bailu build really capitalizes on her healing abilities, keeping her mainly as a background support to heal the rest of the team. As such, most of the best additions to a Bailu build involve increasing her outgoing healing value rather than any damage or attack stats, as well as keeping Bailu herself alive as long as possible with the best max HP available to her.

Best Bailu Light Cones

The best Bailu Light Cones are:

  • Time Waits for No One (five-star)
  • Post-Op Conversation (four-star)
  • Shared Feeling (four-star)
  • Cornucopia (three-star)

The best Light Cones for Bailu increase her outgoing healing value, as we’re building her purely as a healer. Time Waits for No One is recommended in game as the best Light Cone for Bailu, and it increases not only Bailu’s own max HP, but also her outgoing healing. This Light Cone also boosts damage dealt by healed allies, giving Bailu a helpful damage ability in battle without actually fighting herself. If you don’t have Time Waits, every other Light Cone listed above also boosts Bailu’s healing abilities. On top of outgoing healing, Post-Op Conversation increases Bailu’s regeneration, and Shared Feeling regenerates allies’ energy when Bailu uses her skill.

Bailu swims through blue waters, surrounded by fish and coral.

Best Bailu Relics

The best Bailu Relic is:

Relic Effect
Passerby of Wandering Cloud (four-piece set) Increases outgoing healing by 10% and immediately regenerates one skill point at the start of the battle.

The best Relic set for Bailu as a straightforward healer is Passerby of Wandering Cloud, as this – as with the rest of this build – further increases the Lightning user’s outgoing healing. The additional skill point could also help you out in a pinch, as this can be used by anyone on the team, further adding to Bailu’s altruistic abilities.

Best Bailu Planar Ornaments

The best Bailu Planar Ornament is:

Planar Ornament Effect Planar Sphere Link Rope
Fleet of the Ageless Increases Bailu’s max HP by 12%. Upon Bailu’s speed reaching 120 or higher, her allies’ attack increases by 8%. The Xianzhou Luofu’s Celestial Ark The Xianzhou Luofu’s Ambrosial Arbor Vines

The Fleet of the Ageless Planar Ornament is one of the best overall, and you will see it in a few of our best Honkai Star Rail builds. It is particularly special in this Bailu build though, as it stacks with her Light Cone to increase her own max HP. Meanwhile, the ability of Bailu, our healer, to further increase the attack of allies makes a huge difference to the wider team.

Bailu Bailu Eidolons

The best Bailu Eidolon is:

Eidolon Effect
Pot of Slumbering Dragon – Level 2 After using her Ultimate, Bailu’s Outgoing Healing is buffed by an extra 15% for up to two turns.

With Eidolons so hard to get on a five-star character like Bailu, we’re taking into consideration the usefulness of the Eidolon itself against how long it will take you to actually get it, so the best with this in mind is Pot of Slumbering Dragon at level two. This Eidolon increases Bailu’s outgoing healing for two whole turns which, stacked with some of the other healing buffs in this build, considerably aids the survivability of your team.

Best Bailu Honkai Star Rail team comp: Bailu, Serval, Pela, and Bronya all appear in an image together.

Best Bailu team comp

The best Bailu team comp is:

  • Serval – Main DPS
  • Bronya – Buff
  • Pela – Debuff
  • Bailu – Healer

Every Honkai build should consider weakness breaks, and so a Lightning DPS like Serval is a great choice thanks to the additional Lightning damage dealt at a weakness break. For support buff, we’ve gone for another character that deals damage on a break, but a different type of damage, so Bronya deals wind damage. She also buffs the team’s attack and gives allies additional turns, which comes in useful for both attackers and Bailu’s own skills.

If you don’t have these characters, you can swap them out with characters with similar abilities. Swap Serval out with another strong Lightning attacker like Jing Yuan. Bronya could be replaced with fire harmony character Asta. Finally, Pela could be swapped out for Silver Wolf, as her Quantum Nihilist traits can also take turns away from the enemy.

Bailu Ascension Materials

Here’s Bailu’s Ascension Materials:

  • Extinguished Core
  • Glimmering Core
  • Squirming Core
  • Lightning Crown of the Past Shadow

Lightning Crown of the Past Shadow is the hardest of the Bailu ascension materials to farm for as they can only be found in one place, the Stagnant Shadow challenge in Backwater Pass. Luckily, Bailu’s other ascension materials can also be found in Backwater Pass, with Cores dropped by Flamespawns and other enemies in that area, as well as in Rivet Town.

With the best Honkai Star Rail Bailu build, you should be able to keep your team going strong throughout the toughest of battles, especially with all those outgoing healing buffs.
