Restricting Magery to One College Only

That's easy.

Magery (One College Only, -40%) costs 6/level. Magery (Two Colleges Only, -30%) costs 7/level. Magery (Three Colleges Only, -20%) costs 8/level. And so on. Adding a college adds 1/level to the costs.

I would have adopted a different scale, with each doubling of the number of colleges cancelling 10% of the limitation; that would integrate better with the rules for different numbers of colleges. But it wouldn't give you a simple N points per college, or per extra college.

I'd pay 6x8=48 for the Fire college, then (4x1) + (3x1) + (2x1) = 9 more points for the other three colleges, for a total of 57 points.

Aha. That makes a lot of sense. I think I'm going to go with this solution.

Thank you!

Since full Magery exists only by buying all colleges individually, it's irrelevant what the cost comparison is to "regular" Magery in default campaigns.

Price the ability based on how many total levels/colleges you'd like a PC mage to take at the starting point total. That is, set the price for the effect you want it to have on the campaign.

Not really an option in GURPS, not for that. The price of One College Only is -40%, assuming the standard number of colleges, at any rate.

The price is whatever the GM wants it to be in his own campaign.
