If you buy Gunblade on Zyra, None of your plants provide the 15% leech on their auto attacks. Even though Gunblade applies to Heimer Turrets and other additional effects.
> UNIQUE – OMNIVORE: Instantly heal for 15% of all damage dealt, including physical, magical and true damage. Area of effect damage only heals 5% for every unit affected.

AaronMoll1 votesWanted to see if the build up could provide a return of zyra mid, since she relies on both auto attacking and her plants to win lane, an item that benefited both would have been useful, in addition a slow to set up your snare and full combo is a decent part of the reason you would want to rush rylai's in the first place.
It's weird that it doesn't work, given spell vamp works with plants, and heimers turrets work with omnivore.
