So, as you can clearly see, this is not complete. There's quit a bit more to do.
But it is something. A big portion of the help came from these threads posted here. So thank you very much. And thank you for future help.
Tell me what you see that I don't.
In regards to the mechanic itself:
I imagine it so - you go over the 4 steps - deciding the target, casting range, duration and effects. Sometimes the order of pickings matters. Sometimes it doesn't.
Each picking has a score. You add them all up. That's the spell level. It is the base for calculation things such as spell DC.
If the spell score is too high, the caster can reduce it by having a very long casting time. Turning it to an out of combat Ritual of sorts.
I know that some of the effects are missing. I wasn't sure about them. But I think I got the bulk.
I, also, am not sure about spelling and such. I want it written down in the clearest, shortest and easiest most possible option. So, remarks for that are welcome as well.
You can also see that there is a term AEGIS. This because it was easier noting options in one step and balancing them afterwords rather then doing so all at once.
I would especially like to thank the thread about seedcasting
and it's compilers. It greatly encouraged me when I was stuck with this list.
Constructive comments are more than welcome.
