Thanks for your response.
Specifically, what I was trying to do is refer to the Magazine Owner itself, via an Ammunition Unit I'm not sure how to go about that. My understanding of the Iterate Magazine effect is that the effect has to stem from the Magazine Owner and will then effect the Ammunition Units. What I was looking for is a way to do the opposite, to have an ability target one of the ammunition units and for the effect tree to jump back to the owner.
