Beidou - Buff Details
Elemental Skill Enhancement
Increases DMG, Reduces Cooldown & Restores Energy
Beidou's new buff lets her hold her Elemental Skill to build momentum, which reduces the skill's cooldown based on the accumulated charge. This also restores a portion of her Elemental Energy, allowing for more frequent usage of her abilities.
Elemental Burst Enhancement
Shreds Cryo RES and buffs Elemental Mastery
While in the Radiance: Stellar-Conduct state during her Elemental Burst, Beidou lowers the Cryo resistance of nearby opponents and increases the active character's Elemental Mastery, though she still requires a team enabler to trigger the Polestar Field to unlock these benefits.
C6 Shreds Enemy Resistance & Increases Team's EM
At Constellation 6, Beidou maximizes her support potential by shredding enemy Cryo resistance and providing an Elemental Mastery buff to the on-field character while active within the Radiance: Stellar-Conduct state.
Needs an Enabler to Activate Stellar-Conduct
With this new buff on her kit, note that Beidou cannot trigger the Stellar-Conduct reaction by herself, and she needs someone like Sandrone who will enable her to create the Polestar Field to unlock these combat benefits.
Constellation Enhancement
Constellation Level 6
