I'm looking at the Challenge System & Difficulties table and I'm partly confused by the Skill Roll column. Do they add onto your d100 roll or do they add to the Total Proficiency? What I mean to ask: Deadly is a -20% modifier, to the d100 roll or the number you have to roll under?
Another thing: I think it would be nice to have a sample of play and a few sample characters to show new players how things should look like.
