Mariner Biya Guide
-10% CD for Ranged + Best Attack Speed
No PvP survivability + Outpaced
Mariner Biya is a secondary team PvE pick whose main value lies in two things: a rare -10% skill cooldown for all Ranged allies and one of the highest base Attack Speeds in the game at 200. She has fallen behind in raw DPS as awakened heroes took over, but her support utility in ranged compositions keeps her relevant — particularly in the Gold Daily Dungeon.
⚠️ Mariner Biya is a collaboration hero — she can only be obtained during her collaboration event. If you missed it, you will have to wait for the collab to return before being able to summon her.
