Beating Wyrm – Disorder

If you’ve been banging your head against the Wyrm Disorder boss in Etheria: Restart and wondering why your team keeps getting vaporized, don’t worry, you’re not alone. This battle is one of the more punishing challenges in the Union mode, and it all comes down to understanding the nuances behind this brutal fight.

In this guide, we’re breaking down everything you need to know about the Wyrm Disorder boss—from its deadly mechanics and essential team-building strategies to in-combat tips that will help you scale your score and survive the chaos.

At first glance, the Wyrm might just look like another high-damage boss—but don’t be fooled. Its mechanics punish unprepared teams hard. The real secret to surviving (and thriving) is debuff management.

Let’s talk about the big one: Spatial Whirlwind. This AoE skill hits all your allies with two strikes of 250% damage. Sounds bad, right? It gets worse. If the Wyrm has fewer than two debuffs on it, that multiplier jumps to 400%, meaning you’re eating a truckload of damage just because you didn’t slap enough status effects on it.

If you’re not consistently rotating debuffs on this boss, you’re going to get wrecked.

Before you load up with control units and DoT spam—don’t. The Wyrm is immune to all control effects and DoT damage. You also can’t mess with its action bar or skill cooldowns.

That means traditional CC heroes like stunners, freezers, or time-manipulators won’t do anything here. Instead, you’ll want raw debuffers, turn-pushers, and damage-dealers who respect the mechanics.

You’ll want to bring heroes who can:

• Apply different types of debuffs to avoid stacking the same one.
• Rotate cooldowns efficiently to keep the debuffs flowing.
• Survive long enough to reach score milestones.

Kloss is a solid pick despite being unconventional. She procs multiple debuffs and can keep them up reliably. Other standout options include:

• Heinrich – Applies heal blocks, defense downs, and other useful effects that count toward your debuff quota.
• Withered Sania – Not only applies debuffs, but extends their duration, which is massive for keeping pressure on the boss.
• Rahu – Brings defense down and some nice utility.
• Friend Support Units – Don’t sleep on this! If you lack a strong debuffer, bring one from your guild or friends list. It can make a huge difference, especially early on.

Pro tip: Don’t overload your team with duplicate debuff types. Instead, bring variety—think defense down, heal block, burn, slow (even if it doesn’t function here, some still count as debuffs), etc.

The key to success? Keep three debuffs active at all times. Not two, not one—three. This reduces the Wyrm’s defense ignore from 100% to almost nothing, letting your units actually survive longer than a couple of turns.

While pushing for higher damage (and higher scores), a “damage-first” strategy can work if you maintain your debuff rotation. The run highlighted in the video managed to hit Double S rank by doing just that—balancing damage with debuff uptime and smart rotation.

Also, don’t underestimate the value of turn pushers. Units that help your team act faster (without manipulating the Wyrm) can keep your debuffers cycling their skills.

What makes the Wyrm Disorder fight great is that it’s actually very doable, even if your units aren’t fully built. In the featured run, many units were only 5-star and not fully skilled up, yet still pushed impressive ranks.

As you continue to invest in:

• 6-starring your units
• Leveling their gear
• Skill enhancements

—you’ll naturally push higher ranks with the same strategy.

The Wyrm Disorder fight is a masterclass in mechanic-driven combat. It’s not about brute force or raw power—it’s about smart team-building and respecting the fight’s unique design. Maintain debuffs, bring the right units, and watch your performance skyrocket.

As Union content continues to evolve, we’ll likely see even more variations of this boss type. But for now, this encounter is a great way to test your roster and maximize your team synergy.
