These spells are ridiculously powerful, a dragon shrunk twice is a pup! And as nothing has more than 50% spell resist, you only have to cast it 4-5 times, for a meager 5 mana each ! Compare that to a 50 mana Fireball that don't kill anything bigger/badder than a bear ..
Same for Growth, that makes very cheap super warriors (combine that with a Crushing blow on your sovereign, and you'll do 100 damage !)
Pls make them less powerful, with let's say -5/+5 attack/dodge instead of -50%.. Or tell me how to mod them !!
