I forgot about web for some reason when writing the idea up, but I would consider it to be stronger then web and affect using items like grease and making both held items no-remove.

basically I envisioned it kind of like a shaman primodial vengeance, hard to land and nasty in well planned situations but not neccesarily an I win button. I guess another way of describing it would be web + grease + iron grip all in one shot.

as per the other concern, uhh the skill wouldn't hinder casting teleport and by and large I would argue teleport is still waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay to spectacularily good at what it does with no real risk so anything that makes it harder is just bringing it into balance.
