Several armies get various kinds of beast riders classed as various kinds of camels. A bit disappointing that lots of things like jaguars are classed not as Cm but as Wb. This is a bit odd. I don't actually see the reason this is necessary. I think it means you can have more than 4 commands.
Spells have a limit of how often they can be used.
I thought the magic rules in general were pretty decent. It seems clear to me that you can cast as many spells as you have pips. The list of spells seems ok and not overpowering. The extra pip die means that the player will be able to cast 0-3 spells a turn. The skill in this system is picking the spells and deciding when to use them.
