Byrna Damage Increases
The Infinite Snowball: How Byrna Damage Increases to 91 Million
The way Byrna Damage Increases is starting to look like a nightmare for defensive teams in Hero Wars: Alliance. Specifically, she is the kind of hero who doesn’t just scale well—she completely breaks the ceiling of battle statistics the longer the fight continues.

In our recent stress tests, we pushed Byrna to her absolute limits to see exactly how her power evolves over time. Ultimately, what we found is a late-battle mechanic that can turn a single cast into a total battlefield swing. If you want to understand how Byrna Damage Increases from 65,000 to over 1,000,000 per strike, you must master her healing-to-attack conversion engine.
How Byrna Damage Increases: The Roar of Nature Engine
At first glance, her ultimate skill, Roar of Nature, looks simple. It deals magic damage to all enemies and heals allies. However, the real danger is hidden in the secondary effect: 100% of the healing from this skill is converted into a permanent Max Health increase until the end of the battle.
Consequently, Byrna is not just a healer. She is permanently raising the survival ceiling of her entire team. Furthermore, every cast makes the team harder to kill, which provides more time for her passive skill, Living Heart, to stack even more power. This creates a loop where Byrna Damage Increases exponentially because the team simply refuses to die.
| Battle Phase | Magic Attack Stacks | Roar of Nature Output |
|---|---|---|
| Initial Cast | Base Stats (~72,000 MA) | 65,000 Damage |
| Mid Battle (60s) | ~500+ Healing Triggers | ~350,000 Damage |
| Late Battle (110s) | 2,500+ Healing Triggers | 1,000,000+ Damage |
Living Heart: Why Byrna Damage Increases with Healers
To achieve these numbers, you must understand the synergy with her violet passive. Every time an ally is healed—no matter how small the amount—Byrna gains 544 Magic Attack. Therefore, the key to seeing Byrna Damage Increases hit the millions is frequency, not size.
The 91M Strategy Team:
In our test, we used a specific lineup to maximize healing triggers:
- Mushy and Shroom: Creates extra units (copies/mushrooms) for more healing targets.
- Maya & Guus: Provide constant, frequent healing “ticks” rather than one big burst.
- Martha: Speeds up the entire team to accelerate the trigger cycle.
- Electra: Her vampirism creates even more individual healing events.

The Strategic Warning: How to Counter Miu and Byrna
Because Byrna Damage Increases over time, the first 60 seconds of any battle are your critical window. If you allow her healing engine to mature and her Roar of Nature to reach its late-battle form, you are not finishing that fight cleanly.
Ultimately, her team becomes too healthy and too strong to stop once the 90-second mark is reached. Therefore, you must design your attacking teams with early pressure in mind. You need tools that can threaten Byrna fast, before her Magic Attack stacks reach the hundreds of thousands.
Final Thoughts
Byrna is a hero who demands respect from the very first second of combat. She is a late-battle conversion engine that turns sustained scaling into overwhelming pressure. Specifically in game modes like the Foundry in Clash of Worlds, she is becoming the undisputed Queen.
