FP to Skill Raise for 1 roll

[Last Pawn]

Thought I'd throw in my nickle (we don't have pennies here). I've done this before using the following approach:

Rules Exemption Perk: Skill Functions As Power
This perk allows a skill, chosen at the time this perk is taken, to function as a power rather than a skill. To qualify for this perk the character must have at least 1 point already invested in the selected skill. The chosen skill may take any enhancements or limitations that the GM deems reasonable, with their usual costs and effects; however, all levels thus modified cost 4 points per level and never afford the character any benefits associated with having the skill at a specific level.

After that you'd just want to add Costs Fatigue at N where N is the number of levels purchased and use the Proportional Cost option from Powers.
