[Uh-Nu-Buh]

Ok, for anyone out there experimenting with spells--some tips:

1. Create your nation first, then any spells that are nation restricted to the new nation.
2. Divine magic should be #school 7. -2 (for nation restriction) -1 (for un-researchable) etc. do not apply.
3. Any changes you make to spells apparently do not take effect to current saved games. You must start a new game in order to test/enact the changes. This is in stark contrast to unit changes (e.g. changing your new light infantry's strength from 11 to 10 will take effect immediately as soon as you save the mod and restart dom III.)

That should do it.
