The best Bailu Light Cone is Night of Fright. This weapon increases her Energy Regeneration Rate by 12%. When any teammate 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, it increases the healed ally’s ATK by 2.4%. This effect can stack up to 5 times and lasts for 2 turn(s).

You can also use Bailu’s 5-star signature Light Cone called Time Waits For No One. This weapon increases Bailu’s Max HP by 18% and Outgoing Healing by 12%. It will also damage enemies equal to 36% of the recorded Outgoing Healing value.

As 5-star Light Cones, they aren’t easily accessible and are dependent on players getting lucky on banners. However, there are a few 4-star Light Cones that can be good choices.

Post-Op Conversation increases the Energy Restoration of Bailu by 12% and increases the outgoing healing of her Ultimate by 20%. Meanwhile, Shared Feeling improves Bailu’s outgoing healing by 12%. If that wasn’t enough, when she uses a Skill, the pint-sized healer regenerates energy for all allies.

Bailu can fit into a variety of Honkai Star Rail team comps.

The best Bailu team comp utilizes Bronya, Himeko, and Gepard. Bronya is a great DPS character and can advance an ally’s actions, meaning you can deliver instant damage or have Baliu deliver a lifesaving heal before an enemy can finish them off. 

Her ultimate also increases the ATK of allies by 36%-72% and enhances their CRIT DMG equal to 12%-18% of Bronya’s CRIT DMG, plus an additional 12%-24% for two turns. Combine this with Himeko’s deadly AoE fire attacks, and you have a recipe for some dizzying damage numbers. 

Lastly, Gepard serves as the team’s tank. His Ultimate, Enduring Bulwark, applies a shield to all allies and absorbs all incoming damage equal to 32% of his health for three turns. Meanwhile, his Technique also increases his allies’ defense by 25% during the next battle.

Not only does this team have great damage output, but the added defensive and healing potential will keep you on your feet during even the toughest of battles. 

So, there you have it. That’s everything you need to know about the best Bailu build in Honkai Star Rail, including the Relics, Light Cones, and team comp you should use.
