Defenses

Defenses, also known as Towers, are the structures heroes use to protect the Eternia Crystals and themselves from the creatures of Etheria. Each hero class and their counterpart (if any) has access to their own unique set of defenses.

The Apprentice and Adept can summon powerful, though frail, arcane towers. The Squire and Countess have access to sturdy blockades and brute-force turrets. The Huntress and Ranger deploys traps which detect and detonate on ground enemies. The Monk and Initiate create auras which apply effects to heroes or enemies inside them. The Summoner creates minions of which he can command. Series EV constructs two-point beams of adjustable lengths. The Jester can deliver presents which may contain a random hero defense. And the Hermit summons organic structures to slowly wither away his foes and provide health regeneration and buffs to ally heroes and defenses. The Barbarian does not have defenses; he uses battle stances instead. In Redux though, he can deploy totems to buff himself and his teammates.

Common Attributes

In contrast to traditional tower defense games, hero defenses are summoned on enemy walkways and can either be destroyed by the enemy or through their own means during combat. Most defenses physically collide with players, enemies and the environment. Monsters will attack (and damage) defenses that block their path to an Eternia Crystal. Traps, auras and beams (except the Physical Beam) are non-physical defenses. These intangible structures cannot be targeted by enemies directly (except for Djinn). A trap is destroyed when it runs out of charges, and an aura dies off when its lifespan expires. Beams go down from either exhaustion or, in the case of the Tower Buff Beam: from the loss of any defense along its length.

All defenses cost mana to summon and occupy a finite supply of either Defense Units (DU) or Minion Units (MU). The latter resource is used exclusively by the Summoner's minions. DU and MU limit the total number of defenses allowed on a map at any given time. Mana can be invested/returned by either repairing, upgrading or selling summoned defenses.

If the builder is active on the map, all of their defenses gain a 33% damage bonus. This also applies to the potency of Healing Auras.
