[JLV]

I gotta say that I strongly agree with Firehorse on this issue. ST is ALWAYS important because of physical things, like getting stabbed or drowning. IQ for Wizards (and magic in general) SHOULD be the most vital stat for anything spell related.

In fact, I agree so much with this, that in my house variant of original TFT, IQ generated a separate Mana Point total (just like ST generates a Fatigue Point total) for use in expending on spells. Players COULD exceed their Mana points by burning ST too, but it wasn't "Fatigue" then, it was actual hits that had to be healed the normal way. Fatigue was then available for all the fatigue things that GURPS talked about (excess burdens, working too hard or too long without rest, desert/arctic survival, and so on), which made the whole thing a lot more sensible to both me and my players.
