The section about untrained skills on page 83 is a little confusing. Is this rule designed to allow anyone who is untrained at a 'trained only' skill (like tumble) to roll a check, with a max result of 10? Or is the intention to limit untrained use of skills that can be used untrained to a max result of 10? I'm leaning towards the first theory, since the second would mean that people with 0 ranks in climb could never even climb a tree. But I'm asking here just to be sure.
