Re: Is there a "penalty to skill roll" modifier for powers?
Not exactly, but it is the direction I am heading for. My idea is to make powers cheaper by imposing a penalty on the skill roll (independent of Active Points), such as: "Skill roll is -1" (- 1/8), which you could apply multiple times, even for a total of -10, -20 or more.
That way, you could have sets of relatively cheap powers (say, magic spells), that require a very, very high skill score in a core skill ("Casting Magic", for example).
