Players can also build Aztec-style pyramids to harness the power of magic from the five spheres of Magic: Sun, Star, Moon, Nature and Soul. The amount of magic available to the player is limited and measured in "Mana", Mana is used by Priests to cast spells, this Mana can be recharged by performing sacrifices at the Pyramids where priests are trained, the amount of Mana per unit depends on the Unit type. Each sphere of magic has different spells available with a vague focus on a specific type. Sun Priests specialise in attack spells, Moon in defensive ones, Nature Priests in Healing, Star Priests in 'debuff' or distraction and while Soul Priests are equally skilled in all fields.
