Demon King Invasion

Build four heroes, each one can be equipped with an elemental core and a rune.

There are five classes: Warrior, Mage, Priest, Paladin, and Ranger.
Five elemental cores: Fire, Cold, Elec, Shock, and Poison.
Four runes: Aether, Myst, Elder, and Storm.

Each combination of class, core, and rune can create a unique set of three abilities. Different abilities have synergy; using them with strategy can significantly increase damage.

Sixty levels in total, each with three difficulties: Normal, Hard, and Nightmare. Demon King's minions gain more abilities in Hard and Nightmare difficulties, and many of them require carefully using hero skills.

Control 4 heroes at the same time or individually.
