Mastering Koleda Belobog: Your 2026 Guide to the Stun Fire Agent

Few agents in Zenless Zone Zero capture the spirit of industrial resilience quite like Koleda Belobog. She’s not the type to sit in a corner office signing papers — this pint‑sized president would rather slam a colossal hammer into a hollow‑borne Ethereal and call it a day. For those hoping to add a rock‑solid Stun specialist to their roster in 2026, Koleda remains a premier choice, balancing raw Fire damage with masterful crowd control.

But assembling an agent like Koleda requires more than just pulling her from the banner. A mountain of materials, careful skill prioritization, and a clear vision for her role in a squad are all part of the blueprint. Think of this guide as your personal construction foreman, walking you through every promotional chip, every upgrade tube, and every tactical nuance so that your Koleda can start knocking enemies flat and lifting your team’s performance to skyscraper heights.

Who is Koleda Belobog?

Koleda is the hyper‑active president of Belobog Heavy Industries, a construction and infrastructure giant in New Eridu. Standing barely at shoulder height next to most of her crew, she defies expectations the moment the fighting starts. With an S‑Rank status, Fire attribute, and Stun specialization, she excels at disrupting enemy attack patterns and opening wide windows for her teammates to unload heavy damage.

She’s an anomaly — a corporate leader who prefers getting her hands dirty on the front lines. That massive hammer she swings isn’t just for show; it functions as an extension of her own stubborn will. And honestly, who doesn’t enjoy watching a tiny powerhouse command a battlefield like it’s just another Monday morning on the loading dock?

Acquiring Koleda in 2026

Koleda can be obtained through the Stable Channel: Star‑Studded Cast, the standard banner that has grown even more generous as HoYoverse rolled out QoL updates over the years. The signature “300 Signal Search” rule still applies — once a player completes their 300th pull on this channel, they are given the power to hand‑pick any S‑Rank agent currently available.

This is the simplest path to guarantee Koleda, and by 2026 the community has widely adopted the strategy of saving standard pulls specifically for this milestone. She has also appeared in a few limited event banners over time, but she’s never been easier to acquire directly than through that 300‑pull selector. Long‑time players who have been sitting on a hoard of Master Tapes can probably just scoop her up on a lazy Sunday afternoon. That’s the beauty of a maturing gacha — patience pays off.

Koleda Materials and Progression

What takes real investment, however, is turning that fresh pull into a fully battle‑hardened agent. Koleda’s promotion and talent upgrade paths require a healthy stock of specific items that blend general Fire‑type resources with Stun‑class components. Let’s break it down, because skipping a material run can leave your team hanging in the hardest Hollows.

Character Promotion Materials

Ascension Level	Key Materials
20 → 30	Scorch Chip x4, Dullahan Fragment x15, Denny x20,000
30 → 40	Advanced Scorch Chip x8, Elite Dullahan Core x10, Denny x40,000
40 → 50	Advanced Scorch Chip x12, Elite Dullahan Core x20, Burning Emblem x5, Denny x80,000
50 → 60	Superior Scorch Chip x16, Magnus Core x10, Burning Emblem x10, Denny x160,000

Players should farm the Stun‑Material domain on days when Fire resources are also in rotation — the overlap saves a surprising amount of Battery Charge. The Dullahan line drops from designated Notorious Hunts, so it’s wise to mark those on the weekly calendar and never let the boss reset go unused.

Skill and Talent Materials

Skill Type	Required Materials (per level)
Basic Attack	Basic Fire Chip x3, Dullahan Fragment x5, Denny x10,000
Special Attack	Advanced Fire Chip x5, Elite Dullahan Core x3, Koleda Key Card x1, Denny x20,000
Chain Attack / Ultimate	Superior Fire Chip x8, Magnus Core x5, Koleda Key Card x2, Burning Emblem x3, Denny x50,000

The Koleda Key Card is a character‑specific drop obtained by completing her Agent Story and weekly boss challenges — this is the bottleneck for most builders. Prioritize her Chain Attack and Ultimate first; both not only dish out massive AoE Fire damage but also trigger her signature Furnace Fire buff.

W‑Engine and Drive Discs

Koleda’s best‑in‑slot W‑Engine amplifies Impact and Daze application, making those stun windows even more reliable. F2P alternatives like “Steam Oven” have gained popularity in 2026 team‑building circles because of their reliable stat scaling without gacha dependency. For Drive Discs, the Swing Jazz 4‑piece set remains the gold standard, boosting the entire squad’s damage when Koleda triggers a stun. It’s a team‑first mentality that mirrors her character: she builds the stage, and her allies perform.

Unleashing Her Abilities: Skills and Playstyle

Koleda isn’t just a one‑dimensional stun bot; her kit encourages a rhythmic dance between offense and defense. Her Basic Attack string applies steady Fire damage and Daze buildup, but the real magic happens when she rotates with teammates.

Her Defensive Assist parries incoming threats and inflicts a massive chunk of Daze, often enough to push an enemy straight into a stun state. A well‑timed swap can completely turn the tide — it’s like watching a tiny construction worker catch a speeding truck and gently set it aside. On the flip side, her Offensive Assist lets her leap into the fray, deal immediate Fire damage, and grant herself Furnace Fire. This buff empowers her Basic Attack with extra slamming power, so chaining assists is the secret sauce.

Both her Chain Attack and Ultimate unleash wide‑ranging Fire devastation. The floor practically ignites under a storm of hammer blows, and each one refreshes that Furnace Fire duration. When you pair this with a properly built Support agent who can amplify damage during stun windows, elite enemies and bosses quickly turn into target dummies.

Here’s the kicker: Koleda’s true ceiling comes from smart positioning. Her Furnace Fire state makes her hyper‑aggressive, so you need to recognize when to commit and when to back off. Over‑extending just because you’re glowing can lead to a swift knockout — and trust me, a stunned Koleda isn’t building anything except a trip to the respawn screen.

Team Synergy and Final Thoughts

Koleda slots beautifully into almost any composition that needs a reliable stun anchor. Pairing her with a Fire DPS agent (like a certain soldier with a flamethrower) creates a dual‑Fire resonance that increases overall damage. Support agents who can group enemies or provide energy regeneration help her cycle through assists faster, meaning more Furnace Fire uptime and more frequent stuns.

One popular 2026 setup runs Koleda alongside a ranged Anomaly unit and a burst‑oriented Attack agent. The idea is simple: Koleda locks down priority targets, the Anomaly unit builds disorder on the side, and the Attack unit detonates everything during the stun window. It’s a rhythm as steady as a metronome — and just as satisfying when you hit that beat.

Building Koleda isn’t about following a strict formula; it’s about embracing that “blue‑collar” tenacity she embodies. Gather the materials, sharpen her W‑Engine, and watch as every fight becomes a carefully orchestrated demolition. The construction may take time, but when the hammer finally drops, you’ll realize the foundation was worth it.
