Concealment Effects and Miss Chance

[Deleted]

Support Issue: Combat
The Issue: If someone has concealment, and has a miss chance, which side of the chance results in the concealed creature taking damage?

Take wraithform because it's fairly simple to understand, a 10% per rank miss chance against purely physical attacks lacking chakra or soul rider effects. If a creature attacks another creature who has wraithform, based on what I understand after checking the handbook, the roll is made on behalf of and from the perspective of the attacker, not the defender. Is that correct, and is the positive result the low roll or the high one?

The handbook says:

Concealment gives the subject of a successful attack a 20% chance of that the attacker missed because of the concealment. Make the attack normally—if the defender accepts the attack, the defender must make a miss chance 1d100 roll to avoid being struck. Multiple concealment conditions do not stack.

So it looks like the defender makes the roll. Also, normally when doing rolls like that people make the "percentage of success" as the lower side of the die roll. So if you had a 10% chance of concealment, if you rolled a 1-10 then you'd have concealment. However I'm not sure this is a rule, and if the rolls are truly random then it shouldn't matter if you specify 1-10 or 91-100 as a success.
