Mana suggestion
I think the magic system is great in Fallen Enchantress, but the mana should be divided into different elements as in Age of Wonders: Shadow Magic:
Earth, Air, Fire, Water, Life and Death
If a sovereign has at least the apprentice talent of an element the mana pool of that element is increased by 1 per season. A shard increases the mana pool of the element by 2 per season if a sovereign has at least the apprentice talent of the element and the shard harvesting tech, but it does not increase the spell damage. The spell damage is increased by the number of talents:
Apprentice (element): 100 % damage of all spells of that element
Disciple (element): 125 % damage of all spells of that element
Mage (element): 150 % damage of all spells of that element
Expert (element): 175 % damage of all spells of that element
Master (element): 200 % damage of all spells of that element
