Re: IQ points, talents, spells, XP
 

Oh. I think I see what you mean now. ITL says "you may assume a character is 20 years of age" when starting. The key words there are "may assume".

You "may also" randomly determine starting age if you want. Something like "18 + 1d6". Of course, all of this assumes they are human...

This leads back to my position that just because they all start with 10 points of skills doesn't mean they have to all be the same age.

Re: IQ points, talents, spells, XP
 

XP cost to buy additional attributes = as listed in ITL p. 45; additional IQ does not give additional points to buy talents or spells.

XP cost to buy additional talents or spells:

25 XP times the minimum IQ for the talent or spell...

...minus 25 XP per point of IQ the character has above the minimum IQ...

...with a minimum cost of 100 XP...

...per point it costs.

An IQ 10 wizard learning an IQ 8 spell, base cost of (25 x 8) 200 XP, the wizard is 2 above the minimum IQ (2 x 25 = 50) for (200 - 50) 150 XP, so he pays 150 XP.

An IQ 10 fighter learning an IQ 8 spell... base cost of 200 XP, the fighter is 2 above the minimum IQ, for 150 XP, and as a fighter his cost for spells is tripled, so (150 x 3) 450 XP.

An IQ 15 wizard learning an IQ 9 talent that costs 2 points. Base cost of 225 XP, the wizard is 6 above the minimum IQ (25 x 6 = 150), for (225 - 150 = 75, minimum 100) 100 XP per point; it's a 2-point talent (100 x 2 = 200), but the wizard pays double that, for a total of (200 x 2) 400 XP. An IQ 15 fighter learning that IQ 9 talent would pay 200 XP.

This works for me.

Setting aside the first sentence which I consider to be a truly flawed rule change...

I like the logic, hate the extra math (I oppose most math on principle ;)).

Re: IQ points, talents, spells, XP
 

Why not a simple cost to add your Nth skill point is 20 * N?

Combine with Attribute advancement of 100, 150, 200, 250, 300, 350 ....
