Level up choices?

There is a great spell for regenerating Mana - I think it is called Magic Spring or something like that. At level 3 it gives +5 mana every time the stack is hit, plus a 30% defensive bonus, for 3 turns. This is a great way to get some mana back later in a long fight. Give it to your stack of Griffins and plonk them down in the middle of a pack of weak spiders or something.

My mage is currently lvl 12. 8 atk. 14 def. 21 int. 3300 leadership. 41 rage, 70 mana.

I hit 3000+ with ice snakes(my current highest damage spell). Overpowering armies are easy pie, I usually don't even suffer losses.

Frog wife, in frog form. Using normal snakes and royal snakes in combination with frog form and Ring of the snake king is kickass =)

Im just wondering, is the skillchoise at lvl up totally random?
as mage ive only gotten rage/leadership so far...and once i found intellect.
Seems a bit boring to not get more mage stats as a mage tbh.
