Darshan's solution looks promising.
A major problem with these skills is that you can't just use a straight stat x5% or similar formula because you will still get many creatures with over 90% or so at which point the game system breaks in several different places simultaneously. A solution like Darshan's that allows characters to have these abilities at over 100%, but still lets the game system cope with that is the way to go.
I particularly like this because it makes use of the fatigue system, which seems to work ok, and can also be used to solve the armour penalties problem by having them only apply to fatigue rolls.
