I made a new Sov, grabbed a number of shards, researched the spell books, but can't, in combat, cast attack spells. It says not enough mana, but yet I can cast greater haste at some large number of points. Now my first test game used and old Sov. I could cast flame dart, fireball, etc, but had none of the new book spells (no t-ports, etc). Not sure what the issue is. Anyone else had this problem?
