I hope that stands as the official rule, it just takes so much bite out of the wild die if rerolling it/ adding 1 to it gets rid of the penalty. Same with glitches.
yeah the "add 1 pip to the result" is the really itchy part about edge and wild dice. How to handle rerolls already has a better roadmap already given... and that's a better position than most rules questions have

Speaking of: I'd be amenable to thinking that "wild dice are flatly immune to the effects of edge", if there weren't the mention already there explaining how it interacts with exactly 1 edge boost. Maybe it should be that
all other edge boosts cannot affect wild dice. Or maybe that you cannot that one specific edge boost on a wild die.
Then again, a wild die is supposed to be a bonus, rather than a 50/50 lul. Allowing you to spend 2 edge to raise a 4 to a 5, or a 1 to a 2, ends up meaning wild dice are a 50% odds of 3 hits and ever so rarely a backfire.
