@RIot about Zyra's passive design

Now when I think of Zyra I think of a plant theme mage who is great at controlling and zoning areas with her plants and long range spells. The only thing that doesn't really fit is her passive. I want to know was her passive inspired by her lore?

For those who don't know I'll do my best to paraphrase it. Zyra is a sentient plant from the Kumungu jungle (P.S can we get some more info on this place and possibly another champ from that area) and dying from lack of food and with a last ditch effort she attacked a sorceress and is possessing her body similar to but doing so made it impossible for her to go back to the jungle.

Now with that out of the let's talk about how that possibly influenced her passive. When Zyra dies that means that the sorceress's dies and that plant is possibly is what Zyra naturally looks like and the spike is her trying to kill another person in hopes of trying to find a new host body.
