i really don't like that source point idea , the problem here is that in the first chapter we played we don't really need those strong spells , i finished one play through with the whole party muted except for my main hero Efan who was a warrior , so it was useless to get un-muted anyway . but what about late game ? i believe it will be really annoying trying to use powerful spells to find out that you lack the source points to do it ..
