I was thinking it would be pretty cool to be able to have a sort of focus that would add +1 caster level to an elemental subschool, or a small damage bonus to non-scaling spells.
This is sorta like the Alchemical Power Component, just its never consumed for any spell, and its kinda expensive.
I was thinking something like 5-8000gp worth of focus, due to a general +1 caster level wondrous item costing 15,000 to buy.
So say for the Air school, a wizard who has a necklace/talisman/whatever made from something like the essence of a small air elemental, or a thunderbirds feathers would get +1 caster level for all spells with the Air descriptor, but in the case for the odd spell like Jolt (the cantrip that only does 1d3 damage at a range of 25 +5/2 a caster level) feet would get +1 damage per dice or something.
Does anyone have any ideas for such a focus for the other schools?
i.e. What would you use as a focus for the wood subschool, void, life, fire, etc...? Also what do you think about the whole idea?

EDIT: someone suggested to me that various rings with different 'stones' as a jewel would be pretty cool thematically.
As in a focus for the Fire School would be a red-gold band (copper/gold alloy) with a tiny fire elemental bound in a jewel like a ruby. The jewel would look to have a roaring flame trapped in it. The water school would have a sapphire with a tiny water elemental in it, looking like it has a whirlpool inside, and the Air school would have a diamond with a whirlwind, etc...
