Maybe replace the 3 special items with 1 special item, that replaces the ward slot?
Maybe it can have different upgrades for free with level requirements, if they are not too complicated.
Jaws of the Beast:
A lion "dragging around" a champion could look a bit awkward, maybe he should just hold them in place and snare them?
Also can Zii jump over terrain, when using this ability? I have the feeling, it shouldn't be able to.
Hunter Senses:
I think this ability is more complicated than it needs to be.
It gives you spellvamp AND a shield to sustain in the jungle. Maybe just increase the spellvamp, while Zii is scouting?
