I've always thought that having no points in an Art just meant you had a 0 to add to your Lab Total, so someone with Cr 0 and Ig 0 could still learn level 5 CrIg formulaics, just from Int+Magic Theory+Aura, not to mention casting very small sponts. This came as a surprise to my troupe, which mostly assumes you need some xp in an Art to activate it. Can anyone settle this for us, preferably with a citation or other authority?
Thanks.
