I noticed that there is a Master Trick that allows you to get Advanced Talents, but not vice versa. Is it allowed?
This is for my Archaeoloninja build.
I do not believe so. Can't find anything indicating it does.
It would, however, be a totally reasonable house rule. Sort of like how a lot of GMs are cool with Ninjas taking "Extra Rogue Talent." It seems more likely to me that it is a minor oversight than a purposeful balance choice.
