Your goal is to conquer each realm by defeating the inhabited creatures, including the guardian of the realm. To do this, you must complete the campaign missions, defeating the waves of creatures by casting elemental spells and destroying them. This allows you to unlock each element and its spells, until you face the guardian of the Obsidian Lair.
