Anyone want a formula to calculate bonus spells?

It's not really any easier to remember than the tables, but it may be of use to someone:

Number of spells of level n=((Ability-10)/2-n)/4+1

provided you follow standard "D&D maths" and always round down.

If you just go by ability modifier you get the much easier.


Number of spells =(Modifier-spell level)/4+1


This does actually have a problem as it produces negative numbers if you try to work out how many 8th level spells a Int 11 person has, but as he cannot cast them anyway I consider that no great failing!

Does this produce an accurate portrayal of the relative power of the various spell levels? I doubt it. These bonus spells have always seemed to me to be icing for the existing spellcasting, and a reward for stat-boosting into the stratosphere. But I just prefer being able to plug away on a calculator than look up tables.
