I'll lead with a thought of my own - it seems to be too easy to hurt people seriously. Maybe instant death should be moved to 5, while 4 turns into mortally wounded, or something?
Agreed, I was just thinking that as I read about Dynamis accidentally killing Astalos. A Power Level 12 spell with the ability to instantly kill someone? That's much too easy.
Perhaps you could spread out power levels a bit, so instead of 1-5 we have 1-10 and have more subtle changes between the levels? Then keep everything else the same. So progression will be slower, but actually more meaningful in the effects that your character can do.
That would certainly solve the other issue I have of durations: they're too rigid. I wanted to make a spell that lasted about 6 hours but I only had the option of 1 hour or 1 day. I had to go for a day but it just felt wrong.
