I will give her a proper read and some more detailed feedback later, but my first three thoughts are:

The passive does something that I find annoying and I see happen quite a lot on custom champ designs - changing a fundamental game mechanic without really needing to. There isn't really any need to halve her autoattack AD. She could be a hybridey magic-attacky champion just by adding on bonus AP-scaling magic damage to her autos a la Orianna. It's like Chekhov's Gun - something as weird as this demands a more important use.

Her tether interaction with her other spells is beautiful, and I love the interactions.

However her tether range is well beyond the range of her W and E, so they wouldn't be able to hit you if you break the tether anyway. Which might be alright in a 'tether is just a bonus you can combo with' sense, but disappoints the promise of interesting enemy decisions.

Will take a closer look later, but smells good so far!
