First I'll start with the ANIMALIA spell concepts. There are two basic header columns to start. The first is a TYPE and the second column is the EFFECT.
The TYPE choice will be limited/ impacted by the sorcerer's IQ. Insects and rodents require a low IQ to manipulate and it gets harder to effect (requiring higher sorcerer IQ) these animals as the Animalia types get smarter and or larger.
So the base ST of a spell is 1 ST to cast. Then it becomes more expensive with the spell shaping (range, time, power of effect). You can cut the cost and time of casting by writing it all down in a scroll or spell book and then casting from it, but of course scrolls and spell books can be stolen or destroyed. That sort of arcane knowledge would be very valuable...the work continues.
