That seems like a Rules Exemption perk to me.

Ditto. I don't know why you'd want that, but it's the same cost. A perk.

I'd call that Luck + Cosmic, Affects effect tables. It's -0% if you can only affect effect tables or +100% if you can affect normal rolls too.

Consider how expensive it would be to get a base skill that high, maybe a perk. Then again, Feverish Defense, Retreat, etc. can jack that up high. I'd apply Cosmic to the active defense per Power-Ups 4.

I can't parse this. What do you mean?

I would never extend it past 9. 9 is plenty. 10+ is just crazy.
