At zero (they are the same IQ as when they started) talent points/spells cost 100xp
At level 1 (One above the original IQ) talent points/spells cost 200xp
At level 2 (two above the original IQ) talent points/spells cost 400xp
At level 3+ (Three " ") talent points/spells cost 500xp

What do you mean by 'levels' in this context? GURPS-like incremental skills (i.e HORSEMANSHIP 1, 2, 3, etc.)?
