@Ray716_Just read your article on Feats. How would you make a feat that allowed you to take 1 class feature you don’t have access to? I'd try to avoid it, honestly. depends on the feature – did you have a specific on in mind?

@Ray716_yes, a wizard getting access to another wizard power, like a necromancer getting a single enchanter power. in other words, a spell can benefit from your standard wizard features, or the one gained from this feat

@Ray716_ in most cases, features from different subclasses were designed to remain separate. stacking them can get ugly.
