Looks good, although I miss the spell book stacking. I think there is a charm picking books and placing them on your shelf.
BTW can someone tell me, what do Chaos and Wrath spell books? Is there a theme or common word for the spells in either of these books.
I assume that summoning books allows you to summon units and also buff your summonings in different ways, while the enchant books contains enchancements for cities, units etc. Please correct me, if I am wrong.
Did the commander get a neck?
