The list of spells seems ok and not overpowering. The extra pip die means that the player will be able to cast 0-3 spells a turn. The skill in this system is picking the spells and deciding when to use them. The same way a hero does. This seemed basically ok to me.
PIP die, river crossing etc.
Also this spell apparently lasts forever until needed. All spells can be cast at any time. If so get your ideas out and on the web or published or whatever. I agree that there are a number of issues in these rules that are far from clear, but they can probably be sorted out. We have no idea what your rules are so can't do anything with them.
