While on various spells, I was checking the "Guidelines" and noticed a possible contradiction...
Perdo Vim Guideline:
I take this to mean a level 10 spell, will reduce the might by 20...???)
Okay, part two:
"Demons Eternal Oblivion"
This seems to say a level 10 spell reduces Might by 10.
The Guidline says level+10, so it should be 20. Is the spell an exception, or is it within the guidline?
Also: Whats the base effect for that spell??? I don't see any base level, then it says +2 for Voice. Does this mean the spell must be a minimum level?
I have always taken this at face value, but I am interested in designing new spells, so it will help to know what it Should be...
All guidlines are for range personal, duration momentary, target individual.
A caster could develop a level 10 spell that would reduce his own might by 20 (if for some reason he had a might score).
Demon's eternal oblivion is range voice. Raising a spell from range person to range voice is a two magnitude boost => 10 levels. Ergo a level 20 DEO spell would have a level calculation of (base 10, +2 range range voice). At base 10 the spell lowers that might of the target by 20.
There is weirdness when you use low level spells because of the issues of changing Ranges, Durations, and Targets below level 5 but IMHO this is why they're called spell guidelines rather than spell rules.
