Bailu

Abundance healer with bouncing recovery, Invigoration, and one-time lethal protection

Released Apr 26, 2023

Bailu heals one ally and then bounces healing to random allies, while her Ultimate heals the whole party and grants Invigoration. Invigorated allies heal when hit, and her Talent can prevent one killing blow per battle. Use her when repeated healing and a one-time safety net are valuable, while remembering the lethal protection can only trigger once.

Bailu GUIDE

Understand Bailu

Useful when…

Restoring one target and then healing random allies with her Skill.
Healing all allies and granting or extending Invigoration with her Ultimate.
Preventing one teammate’s killing blow per battle and immediately healing that ally.

How does her healing work?

Singing Among Clouds heals one ally based on Bailu’s Max HP plus a flat amount, then heals random allies twice at the listed level-one parameters. Each subsequent heal is reduced by 15% from the prior one. Her Ultimate heals all allies, applies two-turn Invigoration to those without it, and extends existing Invigoration by one turn; Invigoration does not stack. While an ally has Invigoration, being hit triggers a heal based on Bailu’s Max HP plus a flat amount. That reaction can trigger twice at the listed level-one parameters.

What does the one-time protection do?

When a teammate receives a killing blow, Bailu prevents them from being knocked down and immediately heals them for a percentage of her Max HP plus a flat amount. This can trigger once per battle. Her Technique grants all allies two turns of Invigoration at the start of the next battle. These effects give her both preemptive recovery from hits and a limited answer to a lethal hit, but do not make her team invulnerable.

What investment fits her role?

The Skill and Ultimate are the main direct healing tools; the Talent supplies both hit-triggered recovery and lethal protection. HP bonus traces align with her Max-HP-based healing, while DEF and Effect RES bonus traces support her listed defensive profile. Basic ATK is Lightning damage to one enemy and is a secondary investment when healing is the priority.

What should you avoid assuming?

Skill healing after the primary target is random and decreases with each bounce. Invigoration does not stack, and the Talent’s hit-triggered heal has a limited trigger count. The lethal protection is once per battle, so after it has triggered, later killing blows receive no second prevention from this effect.

Limitations and tradeoffs

Skill’s secondary heals are random and diminish after each heal.
Invigoration does not stack and its hit-triggered healing has a limited count.
The lethal protection only prevents one killing blow per battle.

Common mistakes to avoid

Assuming Skill’s follow-up healing always reaches the ally who needs it; secondary targets are random.
Treating Invigoration as stackable or unlimited in trigger count.
Relying on Bailu’s lethal protection more than once in a battle.
