Do pets receive a sight benefit from their Parents' Oracle's Elixir?
Do Champions that make/obtain pets in game gain sight of stealthed champions or Wards vis a vis their pets if they have an Oracle's Elixir?
Maokai (seedlings) Annie (Tibbers) Malzahar (Voidling) Yorick (Ghouls) Mordekaiser (Ghost) Zyra (Plants, Seedlings)
Oracle's Elixir: Grants 750 radius stealth detection to champion until death.
As you can see the radius is around the champion and has nothing to do with pets.
