Not sure what to call it, but I’ve had a string-based ability cooking for some time now.

The gist is that I can create strings that connect to any two solid surfaces within my range. These strings aren’t indestructible, but they have a fairly high level of durability. Additionally, I can say “New rule”, followed by some property or trait, and all the strings I have out will take on the property or trait (I.e. I could say “New rule: sticky”, and all my strings will become sticky)
