Zenless Zone Zero Koleda Belobog is an S‑rank Fire‑attribute, Stun‑focused Agent and the young President of Belobog Heavy Industries. Wielding a massive hammer, Zenless Zone Zero Koleda triggers Furnace Fire via EX Specials or Chain Attacks, consuming it to unleash high‑damage, high‑daze enhanced Basic Attacks—especially when paired with Ben, her Bear‑themed Bangboo partner. Her Core Skill “Demolition Hammer” boosts Daze on Furnace‑powered hits, and its Additional Ability grants stunned enemies up to 35% increased Chain Attack damage.

Zenless Zone Zero Koleda Guide: Conclusion
Zenless Zone Zero Koleda is a powerhouse when it comes to stunning enemies and setting up devastating Chain Attacks. Though her pace is slower, her Furnace Fire mechanic and heavy Daze output make her a reliable breaker in stun-based teams. With proper support, she enables huge burst windows and thrives in coordinated setups. Whether smashing through mobs or disabling elites, Zenless Zone Zero Koleda proves that size doesn’t matter when you’ve got a hammer and a whole company backing you.
Frequently Asked Questions (F.A.Qs)
❓Can Koleda work in free-to-play teams?
Yes! You can pair her with starter units like Corin for DPS and Nicole for buffs. Using Ben or Avocaboo covers Stun or healing. Even without top-tier pulls, Zenless Zone Zero Koleda is effective thanks to her utility and base kit.
❓What are her weaknesses in gameplay?
Zenless Zone Zero Koleda’s biggest drawbacks are her slower animations and heavy reliance on EX energy to maintain Furnace Fire uptime. If interrupted or unsupported, she may struggle to keep pressure, especially against mobile enemies.
❓How can players obtain Koleda?
She’s available on the Standard Banner as an S-rank Agent. Her drop rate is shared with other S-units, so it may take 50-80 pulls (depending on luck or pity system) to obtain her without a rate-up banner.
❓Does Koleda have any trust events?
Yes! Burnice’s side story “Learn About Zenless Zone Zero Koleda’s Troubles” in Version 1.2 includes dialogue events that deepen her character. Completing it earns Trust points, Denny, and small rewards like Polychrome and materials.
