Thank you! That's what I was thinking, but needed to "hear" it from someone else! This also gives me the okay for my other idea, which was having two characters that function as one! What that looks like is at first, they will have the ability "Teamwork" that lets me roll with advantage whenever the two work together to accomplish something only two people (with the proper equipment) can accomplish! From there, abilities can be gained that only makes sense for one of the two, however both story and mechanics-wise only that one character can do it. In practice this would look like if the plot splits the two up, then they get the condition "Separated" and until that is resolved, one can only do what they know how to do well, and of course the Teamwork ability would become unusable. It is important to note since the two characters are functionally one, they share an archetype, and a common milestone pool.
