The strategic landscape of Fire Emblem: Engage received a significant evolution in 2025 with the release of its fourth and final wave of DLC content. This expansion introduced a suite of five new advanced classes, each designed to challenge veteran commanders and reshape established team compositions. Acquiring these powerful assets, however, is no simple feat; they are the rewards for conquering the formidable trials of the Fell Xenologue, a parallel story campaign that tests the limits of any player's tactical acumen. Among these new tools of war, two are optional classes that can be applied to existing units, offering flexible new roles, while three are unique, character-specific classes tied to new allies recruited from the Xenologue's world. The choice of which unit to bestow the optional classes upon is a critical, one-time decision per playthrough, demanding careful consideration of a roster's strengths and weaknesses.

🎯 Optional Classes: The Mage Cannoneer & The Enchanter

Upon completing all six chapters of the Fell Xenologue, commanders earn the right to create two powerful new unit types: the Mage Cannoneer and the Enchanter. Each requires a unique, single-use item—the Mage Cannon and Mystic Satchel, respectively—to initiate the transformation. The process is specific: a unit must first be promoted to any standard Advanced Class using a Master Seal before they can be reclassed into one of these new specialties.

The Mage Cannoneer: Artillery Support

a-comprehensive-guide-to-fire-emblem-engage-s-wave-4-dlc-classes-image-1

This class is the army's long-range artillery platform, a unit that operates like a living siege engine. Eschewing traditional weapon proficiencies entirely, the Mage Cannoneer wields magical cannons with immense range, rivaling spells like Bolting. Its true strength lies not in raw damage but in battlefield control and disruption.

  • Class Skill - Let Fly: A guaranteed-hit, area-of-effect attack that triggers at the start of the next player phase. The trade-off is the loss of the equipped weapon, making timing crucial.

  • Class Growths: Notably high in HP, Dexterity, and Defense, making it surprisingly durable for a backline unit.

  • Role & Strategy: The Mage Cannoneer fires specialized rounds that inflict potent debuffs such as Poison (damage over time) and Silence (prevents magic use). It functions as the strategic linchpin of an army, setting up enemy formations for your frontline units to dismantle, much like a master chess player sacrificing a pawn to expose the king. Characters with balanced growths or high Dexterity excel here.

Recommended Units for Mage Cannoneer:

Character Reason
Clanne His mixed growths adapt well to the class's supportive role.
Boucheron High HP and Build complement the class's durability.
Mauvier Solid all-around stats make him a reliable artillery officer.

The Enchanter: The Master Artisan

If the Mage Cannoneer is artillery, the Enchanter is the mobile armory and alchemist combined. This class is pure utility, a force multiplier that turns the tide of battle through item mastery rather than direct confrontation. It requires proficiency in Fists and Knives.

  • Class Skill - Convoy: Allows the unit to access the shared convoy mid-battle to deposit or retrieve items, offering unparalleled logistical flexibility.

  • Class Growths: Leans towards Strength, Magic, Dexterity, and Luck, supporting its versatile toolset.

  • Role & Strategy: The Enchanter's power comes from two unique commands: Item Surge (enhances consumables used on allies) and Weapon Surge (temporarily buffs all weapons of a chosen type for the whole army). It can also use daggers to apply poison. This class is the adhesive that binds a team together, functioning like a master conductor ensuring every instrument in the orchestra performs in perfect harmony. Agile, supportive characters are ideal candidates.

Recommended Units for Enchanter:

  • Yunaka: Already a dagger specialist, she transitions seamlessly into this support/utility role.

  • Framme: Her inherent supportive nature aligns perfectly with the Enchanter's toolkit.

  • Jean: High growth potential allows him to maximize the class's statistical benefits.

⚔️ Character-Locked Classes: Unique Recruits

The Fell Xenologue also introduces three new allies, each arriving in their own unique, irreplicable advanced class at Level 20. These classes learn their exclusive skill at Level 25 and cap at Level 40.

Melusine (Zelestia): The Sky Sovereign

Zelestia's personal class is a flying cavalry unit that soars across the battlefield like a storm cloud laden with lightning. It boasts high proficiency in S-rank Tomes and A-rank Swords.

  • Class Skill - Soulblade: When attacking with a sword, damage is calculated using the average of the foe's Defense and Resistance. This makes her terrifyingly effective against both heavily armored and magically resistant targets.

  • Synergy: Her excellent personal growths in Magic, Strength, and Speed, combined with the class's balanced growths, create a hybrid unit capable of devastating physical and magical assaults from the skies.

Fell Child (Lance) - Nel: The Nimble Phalanx

a-comprehensive-guide-to-fire-emblem-engage-s-wave-4-dlc-classes-image-5

Nel embodies a swift and deadly lance-wielder, a combatant who moves with the precise, relentless grace of a weaving needle.

  • Class Skill - Resist Emblems: Reduces damage taken from Engage Attacks by 20%, a crucial defensive tool in the late game.

  • Role: With high personal Speed and access to lances, she excels as a mobile frontline duelist who can exploit weapon triangles. She is a well-rounded physical unit without obvious weaknesses, perfect for holding key positions.

Fell Child (Axe) - Nil: The Unbreakable Bastion

a-comprehensive-guide-to-fire-emblem-engage-s-wave-4-dlc-classes-image-6

Nil is the embodiment of raw, physical power—an immovable object and an unstoppable force rolled into one. His class is a defensive juggernaut with phenomenal HP, Strength, and Defense growths.

  • Class Skill - Spur Emblems: At the start of each player phase, fills the Engage meters of adjacent allies by 1. This is arguably one of the most powerful support skills in the game.

  • Role & Weakness: He is designed to be an axe-wielding anchor for the front line. However, his pitiful Luck growth makes him susceptible to critical hits, adding a layer of risk to his otherwise dominant presence. His true value is enabling his allies to unleash their Engage forms with dizzying frequency, turning the entire front line into an engine of transformative power.

In summary, the Wave 4 DLC classes for Fire Emblem: Engage offer deep strategic variety. The optional Mage Cannoneer and Enchanter provide customizable, high-utility roles for existing armies, while the unique Melusine, Fell Child (Lance), and Fell Child (Axe) classes bring powerful, specialized newcomers to the fray. Mastering their synergies is the key to conquering Elyos's greatest challenges.
