Scribing Spell Costs

[PlzBreakMyCampaign]

In the spirit of the Shrodinger Wizard topic, I'd like to discuss Scribed spell costs and their balance. It's common knowledge that the RAW low costs allow wizards to hold every spell they could want in their spellbooks are higher levels.

Though I'm aware that a WBL hit is a bad way to balance higher level spells, I'd like to propose the following increased costs on scribing spells as a start. This serves as a targeted nerf on prepared casters and could be expanded even to other casters that know all their spells. I'm thinking either:

x sub n = x sub (n-1) * 3      or      x sub n = x sub (n-1) * 4

0th: 15      5
1st: 45      20
2nd: 135   80
3rd: 405      240
4th: 1,215   960
5th: 3,645   3,840
6th: 10,935   15,360
7th: 32,805   46,080
8th: 98,415   184,320
9th: 295,245   737,280

It certainly obliviates the 'gotta catch'em all' mentality. Thoughts?

(oh noes math class run away before it gets OUCH!!)

1e required a proto-type-ish of Spellcraft check,
to be able to learn any given spell, and had a
maximum # of spells known per level.
I mean it's rather arbitrary, like a Sorc.


I wonder how long the argument threads would
get on the old wotc junior boards, if a Sorc
got 2 spells known with 3 daily uses, versus
a Wiz getting 3 spells know with 2 daily uses.
I bet it'd be longer than the Paladins code threads.
