Her Skill, Abundance Among Clouds, heals a target ally and then jumps to another ally, healing them two times with reduced effectiveness. Bailu can increase the amount of HP she can heal by raising her own Max HP. Being able to heal two team members in one go makes her a lot more efficient than Natasha, whose Skill only targets a single ally.

Bailu’s Ultimate, Leap of Marsh Drakon, heals all allies at the same time and once again is partly based on her own Max HP. Bailu’s Ultimate also applies the Invigorated effect. An ally with Invigorated automatically heals HP when they are hit, which can trigger up to two times. 

Bailu can revive an ally thanks to her Talent, Gourdful of Elixir, once per battle, which is very powerful. You can boost the value of Invigorated even more through her Eidolon levels, which you gain by getting duplicates of her on the banners. On level 1, Invigorated allies that are healed up to their Max HP regenerate Energy as well. Levels 2 and 4 boost Bailu’s healing power after her Ultimate and allow her to buff her allies’ damage after healing. Level 6 enables her to revive two allies during a battle. A fully upgraded Bailu provides a ton of value, it’s safe to say.

Honkai: Star Rail – Bailu: best Light Cones

Bailu has access to a signature Light Cone, which is named Time Waits for No One and is the best option for her.

Time Waits for No One increases the wearer’s Max HP and Outgoing Healing, which in Bailu’s case are both significantly boosting her healing power. In addition, this Light Cone will once per turn record the Outgoing Healing value for a heal and then deal damage to a random enemy based on that amount when the character healed by the wearer makes an attack. The Damage Type of this attack depends on the wearer of the Light Cone, which thus allows the healer to contribute some damage output to the team.

Best Light Cones for Bailu:

• Time Waits for No One (5-Star)
• Night of Fright (5-Star)
• Hey, Over Here (4-Star)
• Warmth Shortens Cold Nights (4-Star)
• Post-Op Conversation (4-Star)
• Shared Feeling (4-Star)
• Cornucopia (3-Star)

Bailu is in high demand in the lore, less so in terms of gameplay these days. / HoYoverse

Honkai: Star Rail – Bailu: best Relics

Naturally, HP and Outgoing Healing are the two critical stats for Bailu you’ll want to boost through Relics. SPD is always a great attribute to boost as well, as it allows for quicker actions and is a requirement for some Planar Ornaments to provide their full effects, so that’s another one to get. The same goes for Energy Regeneration, which allows a character to get their Ultimate into action much sooner.

Best Relic Sets for Bailu:

• Passerby of Wandering Cloud (4) – +10% Outgoing Healing, recovers one Skill Point at the start of battle.
• Messenger Traversing Hackerspace (4) – +6% SPD, +12% SPD for all allies for one turn after the wearer uses their Ultimate on an ally.

Best Planar Ornaments for Bailu:

• Fleet of the Ageless (2) – +12% Max HP, +8% ATK for all allies when the wearer’s SPD is 120 or higher.
• Sprightly Vonwacq (2) – +5% Energy Regeneration, the wearer's action gets advanced forward by 40% upon entering battle when their SPD is 120 or higher.
• Broken Keel (2) – +10% Effect RES, +10% CRIT DMG for all allies when wearer’s Effect RES is 30% or higher.

Prioritize the following Relic and Planar Ornament stats for Bailu:

• Head – HP (Primary), HP%, SPD, Effect RES, DEF%
• Hands – ATK (Primary), HP%, SPD, Effect RES, DEF%
• Body – HP% (Primary), HP, SPD, Effect RES, DEF%
• Feet – SPD (Primary), HP%, HP, Effect RES, DEF%
• Planar Sphere – HP% (Primary), HP, SPD, Effect RES, DEF%
• Link Rope – Energy Regeneration (Primary), HP%, HP, SPD, Effect RES

Honkai: Star Rail – Bailu: best teams

Bailu is useful on basically any team that needs a healer, although she comes with a weakness compared to most of her 5-Star peers: She does not possess an ability that can cleanse status debuffs. This means that Bailu can’t wake up stunned characters or purge DoT effects, to name some examples. That’s fine for most of the story, but is a deadly drawback in endgame content.

• Seele (Main DPS), Bronya (Support), Pela (Support), Bailu (Support)

This Seele hypercarry team from version 1.0 remains a solid one – Bronya can manipulate the turn order in Seele’s favor, while Pela shreds the enemy DEF and removes buffs. Bailu keeps up with healing and can bring back a fallen character, if necessary.

Bailu's Ultimate is an excellent tool to keep the team healed up during intense battles. / HoYoverse

Honkai: Star Rail – Bailu: ascension materials

Here’s everything you need to know to get Bailu ascended to the maximum level and upgrade all of her talents.

Bailu requires the following ascension materials to get to level 80 in addition to the necessary XP:

• Credits x308,000
• Extinguished Core x15
• Glimmering Core x15
• Squirming Core x15
• Lightning Crown of Past Shadow x65

You can collect Cores from enemies in Backwater Pass and Rivet Town as well as the Simulated Universe. You can create or exchange them through the Omni-Synthesizer on the Astral Express, too. Extinguished Cores are one of the base materials you can easily farm through the Daily Assignments to your characters, making for a steady income of the material. Storm’s Eye is dropped by the Stagnant Shadow (Corridor of Fading Echoes) or gained through exchange. The best source of Credits are the Golden Calyxes found on many worlds.

Bailu requires the following materials to upgrade her combat abilities and Traces:

• Credits x3,000,000
• Extinguished Core x41
• Glimmering Core x56
• Squirming Core x58
• Seed of Abundance x18
• Sprout of Life x69
• Flower of Eternity x139
• Guardian’s Lament x12
• Tracks of Destiny x8

For the materials already mentioned, check above. Seed of Abundance, Sprout of Life, and Flower of Eternity can be farmed in the Crimson Calyx (Backwater Pass). As usual, you can create the high-level materials by investing lower-level materials in the Omni-Synthesizer on the Astral Express.

Guardian’s Lament is rarer material only gained from the Echo of War (Everwinter Hill) domain, while Tracks of Destiny can be obtained during time-limited events, the Embers Exchange, the Nameless Honor, or as a Simulated Universe Points Reward.
