Mana () is a resource that's used to cast or research spells.
There are several ways to generate mana:
- Captured power nodes can generate mana each turn if the owner has studied the appropriate sphere of magic.
- Heroes generate 5 every turn for every level of Spell Casting they possess. Leaders generate an additional 5 every turn.
- Mana crystal resources may be found on the world map.
The total amount of mana a leader can produce per turn before any spending is called their mana power base. A leader's power base can be allocated toward research to discover new spells or stored as mana crystals for future spell casting. Only freshly generated mana can be used for research; once mana has been stored, it is no longer available for research purposes.
If a leader is unable to produce enough mana each turn to cover the cost of their enchantments and summoned creatures, their mana production can be negative. Their mana reserves will continue to deplete each turn until they run out. When there is no longer enough mana to power ongoing spells, the spells will expire immediately until mana production is no longer negative.
Mana can be given to other leaders as tribute.
