Kalran: Tales of the four nations/Epic units

Built to break through a deadlock, and is the essence of the commanders style, the Epic units is the strongest, and largest, units in the game. Defined as an incredibly powerful unit, often taking a long time to produce and expensive. An epic unit is able to engage and defeat entire armies of ordinary units. Only another epic (or a unit the epic cannot attack, such as air units) can fight them one-on-one with any hope of surviving without taking massive casualties.

They usually make use of experimental and/or classified technology, hence their considerable price. Even commanders wealthy enough to afford two or more can ordinarily only obtain one at a given time. They often require customized and dedicated infrastructure in order to produce or maintain, further adding to their cost and rarity. Epic units will announce their construction across the battlefield.

Though only buildable at the highest tier, the highest commander rank, and limited to one. Each epic unit has the power to crack an enemy base given enough support from allied units, or even by themselves. Either armed to the teeth or bearing their faction's strength at full force, these units can easily turn the tide of battle and is comparable to a superweapon.

Production
Due to their uniqueness each of the factions have four different ways to build theirs.

Earthborn (Dwarves, Fenrir, Xiagui, Goliath), ADF, and Ouroboros
The Earthborn requires a dedicated structure to produce their epic.

Waterborn (Humans), Byzalem, and Asura
The Waterborn builds their epic directly from their HQ once they reach the appropriate rank.

Fireborn (Orcs, Rokhari, Salamander, Mukasura), Guilds, and Horde
The Fireborn builds their epic in a dedicated tab. Before directly deploying it near a HQ.

Windborn (Elves, Navaheim, Nekomata, Faunus), Tenko, and Reclaimers
The Windborn buildstheir epic from a production structure, depending on the unit itself. (mainly their epic is either produced from their vehicle structure or aircraft structure)

Unique mechanic
Due to their size and complexity. Epic units can't be transported but they are universally amphibious, but unless stated they can't use their weapons when not in their environment, and don't have health in the traditional sense, instead each epic unit has hardpoints, which could be a weapon, a wheel/leg/track, or a gadget that enables their ability, that must be destroyed, not only damaging the epic but weakening it by depriving them of a weapon, a defense, or an ability, and once all hardpoints are destroyed its core is exposed. An epic is considered destroyed once its core is destroyed, but be wary as these hardpoint can be easily repaired.
