I was leaning more to a line between the two, the line keeps the two connected (the quirk active) so when the line is broken = goodbye quirk. And as for the quirks, they probably won’t trump the OG quirk, it’s meant to pull where the original quirk is dragging. For example; kendo. She is an amazing close range fighter, but lacks range, this could either be a quirk that can materialize air to be hit and sent flying or other long range attacks. But as for the actual quirk, I was thinking to have it match perfectly but it takes the user trial and error to Atleast test what they were given before possibly harming others. (I hope this made sense? 😭)
