This is, by the way, nonsense with a minimal number of spells. I already defeated all the Darkness creatures on the map...
The problem is that 3 levels of Darkness spells gave me Blind and Necromancy (a very useful spell for a living army:rolleyes:), but subsequent spells are not available:mad:.
Of course, I hope to still "win" on Recruit difficulty, but it's so frustrating to play as a mage without magic:(
