D&D spells

[yojimbo]

I'd be inclined to set max spell level a character can cast to POW-10. Spells would have a MP cost of its level (this would make magic users more like 3e sorcerers or psions).

To simulate leveling up maybe have a Arcane Knowledge skill which determines what level of spell you can understand (10% for each level) and determines the mutliplier for POW to calculate your magic points (x1/3, x1/2, x1, x2, x3, x4, etc for every 5% increment). Clerics would use Allegiance (deity) instead.

Then I'd make characters read grimoires (which would function like CoC tomes) in order to acquire new spells.
