you want things that can't be done. You either make a gateway spell for free and give ti too all nations or restrict it to 3.. can't give ti to a single mage.

Summoning units can be done, summoning in combat can only be done with regular spells not with self made spells.

I don't see why the better suggestions for the clockwork assasin would be moving it out of your general mod idea.
