Great concept, but a nightmare description. Imagine the tooltip of his core upgrade when combined with trinket.

I think that with better scaling/utility like this, this could be actually a decent item to take one of the six basic slots. Otherwise there is no need to have this item in the trinket slot, it could be just champion's passive (and choosing the upgrade would be done like with Kha'Zix evolutions).

I'm actually not a fan of Rengar having the Bonetooth Necklace as a trinket - it could be his passive's description, since purchasing the item costs nothing and changes almost nothing.
