While Evo Defense: Merge TD doesn’t use traditional RPG-style classes like a typical MMO, every unit in the game belongs to a specific class that defines its role in combat. Understanding how these classes function is essential for building effective loadouts, activating Class Bonds, and adapting to different game modes.

Each class comes with a distinct battlefield purpose, as well as a Class Passive that enhances its performance in specific scenarios. Whether you’re clearing early PvE stages or pushing into tougher waves, knowing what each class contributes will help you make smarter decisions both during runs and when preparing your lineup.

Below is a breakdown of all available classes in Evo Defense: Merge TD and what they bring to your team.

Mage

Mages are high AoE damage dealers designed to eliminate clustered enemies quickly. They typically deal wide-area damage from mid-range, making them ideal for wave clearing, especially in early and mid-game stages where enemies appear in groups.

Their class passive increases Crit Rate by 5%, allowing them to scale effectively with damage-enhancing upgrades and enhancements. Because many Mage skills have longer cooldowns, they perform best when paired with control units like Ice Mage or when supported by attack-speed boosts from Support units. If your strategy revolves around burst damage and efficient wave control, Mage units are a core component.

Support

Support units focus on enhancing allies rather than dealing direct damage. They provide buffs, resource benefits, or temporary boosts that increase the overall efficiency of your formation.

The Support class passive grants 10 extra Silver Coins each time a Support unit is merged, making them economically valuable during matches. This passive alone makes Support units strategically important, especially in longer runs where resource generation determines how many summons and enhancements you can afford.

Although they don’t shine on their own, Support units become extremely impactful when paired with strong DPS classes like Mage or Archer.

Controller

Controllers specialize in crowd control and enemy disruption. Their primary purpose is to slow, freeze, or otherwise delay enemy advancement, giving your damage dealers more time to eliminate threats.

The Controller class passive prioritizes attacking Elites and Bosses while dealing 20% additional damage to them. This makes Controllers particularly valuable in boss-heavy stages or elite waves where raw DPS alone may not be enough.

In Evo Defense: Merge TD, board control is often more important than raw damage. A well-placed Controller can extend the time enemies spend within your damage zones, multiplying the effectiveness of AoE and poison-based units.

Archer

Archers are long-range physical DPS units that excel at targeting high-HP enemies. They typically focus on single-target damage, making them ideal for eliminating priority threats before they reach your Fort.

The Archer class passive increases damage based on distance, scaling up to 20% the farther the target is. This encourages strategic placement to maximize damage output.

Archers are best used as sustained damage dealers, complementing AoE-heavy Mages. When properly positioned, they can act as reliable boss killers or elite finishers.

Warrior

Warriors are melee-focused units that deal high close-range damage. They prioritize enemies with the lowest HP and function best when enemies are already near your Fort.

Their class passive increases damage by 20% against enemies within four tiles of the Fort. This makes Warriors particularly strong in defensive or recovery situations where enemies break through your frontline.

While not always optimal early in a run, Warriors can be highly effective in later waves when enemy density increases near your base.

Poisoner

Poisoners specialize in damage over time (DoT) mechanics. Instead of dealing massive burst damage, they apply poison effects that scale over time, making them excellent for prolonged fights.

The Poisoner class passive allows poison damage to stack up to six times, significantly increasing sustained DPS potential. This stacking mechanic makes Poisoners especially strong against high-HP enemies and bosses.

They synergize well with Controllers, as slowed enemies remain within poison zones longer, maximizing total damage dealt.

Summoner

Summoners create additional units or creatures that assist in defending the Fort. Rather than relying on direct tower damage, they overwhelm enemies through sustained presence and defensive layering.

The Summoner class passive restores 20 HP to the Fort for each summon created. This makes them uniquely defensive, offering sustain that can compensate for leaks during difficult waves.

Summoners are particularly useful in endurance stages or when attempting to complete levels with 100% HP for full chest rewards.

Activating Class Bonds

Beyond individual passives, Evo Defense: Merge TD also features a Class Bond system. By building a team with different classes such as Mage, Support, Warrior, Archer, and Controller, you can activate a +10% damage bonus.

However, activating the full bond isn’t always mandatory. Some stages favor specific classes, so adapting your lineup to match enemy weaknesses is often more effective than forcing a balanced composition.

Understanding class interactions is more important than simply stacking damage.

Although Evo Defense: Merge TD keeps its class system simple, each class plays a distinct role in combat. Whether you focus on AoE clearing with Mages, control with Controllers, sustained damage with Poisoners, or defensive support through Summoners, your team composition directly influences your success in every run.

By understanding how each class functions and how their passives impact combat, you can build smarter loadouts and make better decisions both in PvE stages and competitive modes.
