After the events of the last game, the corruption had spread to such an extent that it had managed to successfully take over the entire kingdom by King Yakmar's mistake of destroying Omnious Shrines which had been cleansed from corruption. The player's role is now to liberate the kingdom, clearing each area one by one, by playing each of the 22 maps and beating them.
There are two base defences: Mages and Warriors. Each instance placed acquires XP; once enough is acquired, the unit levels up and can be given an upgrade. Depending on the rank in question, one of a number of things may be done:
- Improve base damage.
- Apply an element, out of Fire, Poison, Cold, Energy, and Physical (Warriors only).
- Apply a special effect, or improve it: Infect, Cripple, Slow and Debuff apply to Mages, while Criticals, Consecrate, Beserk [sic] and Armour Pierce apply to Warriors.
- Pick a skill for the unit, or a second special effect based on that skill.
- Apply a Legendary Upgrade to a unit.
UpgradesEditThere are two Legendary Upgrades: Necrosis, which increases a unit's damage based on its kill count, and Holy Light, which improves all of a unit's stats, as well as increasing its range.
The attackers are all creatures, undead, and people corrupted by the evil. Each individual attacker has one resistance and one weakness, for -50% and +50% damage for the affected elements respectively. All units also have HP, Armour, Gold, and XP values, (possibly) in addition to special conditions and immunities to either splash damage, Infect, Slow or Debuff.
Attackers can have one or multiple of Regenerating (regenerates health over time), Absorbing (the resistant element actually gives health), Flying (restricts attacks which can reach it), and Fast (moves faster).
