More things to spend XP on.

[Chris Goodwin]

How about improving your ability to use a spell that you already know?

Spell Improvement: You can spend XP on spells that you know, to improve your effective knowledge of them. The first level of this on a particular spell costs 100 XP; the next level costs +200 XP; and so on, up to a maximum +500 XP for the fifth level (Rule of Five). Each level either reduces the effective minimum IQ of that spell, for the caster only, or grants you +1 to DX for purposes of casting it. Reducing the minimum IQ alleviates the need for gestures, incantations, materials, and whatnot, that the caster has to perform for that spell. This amount is tripled for non-wizards, but otherwise works the same way. You have to already know the spell in order to make use of this; you can't use XP to reduce the IQ requirement for learning it in the first place. If your IQ drops for whatever reason, you can still use the spell, though you'll find it more difficult, potentially requiring the additional accoutrements.
