Zibai Build and Guide

Zibai is a 5-star Geo Sword user most commonly played as an on-field Lunar-Crystallize Main DPS. Her gameplay consists of gathering resources from her enhanced Normal Attacks and Lunar-Crystallize reaction triggers to use her special Skill to deal direct Lunar-Crystallize damage. As a Moonsign unit, she is deeply connected to her unique reaction, which is mandatory to play her effectively. 

Lunar-Crystallize is a reaction that replaces Hydro Crystallize when certain Moonsign characters such as Zibai, Linnea, or Columbina are on the team. It is triggered the same way, and doing so spawns intangible Geo Constructs called “Moondrifts” that count for enabling the effects of a team’s Geo Resonance; triggering the reaction three times causes the Moondrifts to launch a “Moondrift Harmony” which deals Lunar-Crystallize reaction damage. The aforementioned characters can also deal direct Lunar-Crystallize damage as part of their kits. All Lunar-Crystallize damage is considered Geo damage, and similar to other damaging reactions, scales with EM, reaction damage bonuses, ignores DEF, and does not benefit from standard DMG%; unlike typical reactions, it can also CRIT. 

Reaction Lunar-Crystallize damage takes into account the level and stats of all characters who contributed to triggering the reaction based on their damage dealt to the enemy - 100% of the stats of the strongest participant, then 50% and 8% for second and third, respectively. Direct Lunar-Crystallize damage is based on the multiplier and the scaling stat listed in the ability instead of level, but additionally enjoys a hidden 1.6x multiplier to its damage. 

Zibai’s Moonsign Passive enables Hydro Crystallize to be converted into Lunar-Crystallize and increases the team’s Moonsign level by 1. It also increases Lunar-Crystallize Base DMG - a separate multiplier to Reaction DMG - based on Zibai’s DEF, to a maximum of 14% at 2000 DEF.

Her core gameplay loop is accessed through her Elemental Skill, which causes her to enter the Lunar Phase Shift state where she gains interruption resistance and can accrue up to 100 Phase Shift Radiance points. She expends 60 of these points to cast her special Skill, which deals two instances of Geo damage; the second hit is dealt as direct Lunar-Crystallize damage when a Moondrift exists nearby. The state lasts for 15 seconds, but is more likely to end well before that as it also ended once Zibai has used this special Skill four times.

Zibai accumulates 10 points per second naturally, but can additionally generate more; her state-enhanced Normal Attacks at a rate of 5 each, or triggers of the Lunar-Crystallize reaction which give her 35 points on a 4 second cooldown. When enhanced by her state her Normal Attacks deal Geo damage, with the fourth attack being direct Lunar-Crystallize damage if a Moondrift is nearby. All this means consistently triggering Lunar-Crystallize is vital to Zibai’s use. 

Her Burst is simple and effective, dealing two instances of Geo damage with the second being direct Lunar-Crystallize. While hardly her main focus, her Burst deals enough damage that Zibai uses it when she can - aided by the fact that her Burst extends her special state to account for its animation time. 

In a similar vein, both her Ascension Passives are strong but hardly eye-catching buffs that double down on Zibai’s need to have the Lunar-Crystallize reaction triggered. The first Passive increases her special Skill’s Lunar-Crystallize multiplier when a Moondrift Harmony is launched, while the second allows Zibai to respectively increase her DEF or Elemental Mastery for every Geo or Hydro character in the team.
