Zmey
Zmey revolves around his Gluttony stacking buff, which reduces damage taken and increases initiative. His ultimate doubles these stacks, making him an unstoppable force if left unchecked. To defeat him, you must bring heroes capable of removing buffs (like Morrigan) and managing HP Destruction (like Metztli), as the boss will try to permanently reduce your team's maximum health.
Key Mechanics
Gluttony
Each stack grants the boss 5% reduced damage taken and 5% increased initiative. These stacks are permanent and cannot be dispelled.
Soul Devour
Zmey's ultimate doubles the current amount of Gluttony stacks. Use heroes with HP Destruction to prevent the boss from reaching critical mass.
Recommended Heroes

Isis
Very useful for cleansing the debuffs the boss applies to your allies with her passive Mother’s Embrace.

morrigan
She is the best counter for this boss. Her ability Omen of the Raven removes all enemy buffs, wiping out its Gluttony in a single move.

metztli
She is vital for survivability. Her ability Endless Night restores 20% of Destroyed HP, countering the boss’s most dangerous mechanic.

Ares
Excellent for raw damage. His Brutal Cleave ignores and removes Shields and Barriers, while hitting for 450% ATK.
