Has Anyone Done a GURPS Mage The Ascension Workup For GURPS 4e

In that case I would use the Margin-Of-Success mechanic from pp. T180-183 to give a penalty to the casting instead of an energy cost. And I would waive the base energy cost, since you get Reactive Reality as well.

If you go with Threshold-limited mana, I would double or triple the the cost for "vulgar" magic and maybe halve it for magic that is very easy to explain in a mundane way.
