From what I understand from the rules, each participant in the contest would cancel each other's Mastery, leaving each with a skill of 1. Therefore, each side would be attempting to roll 1 on d20, any success effectively being a critical. This also seems like a colossal waste of time, trying to roll 1s on a d20... Is this true, or am I being dense?
I've read through many examples on many sites and rules, and all of them always have an example such as 10W vs 15W dropping down to 10 vs 15...
Thanks for the insight...
