I propose to change to current tooltip of the sated devourer passive into something like this:
Unique Passive - Phantom Hit: "Every time your champion deals damage with a basic attack, the next basic attack in 2 seconds will trigger a phantom attack that triggers all on hit-effect. This effect will apply after every standard basic attack. The Phantom Hit doesn't apply effects of basic attack's modifier on single hit (like nasus q, rengar q ecc...), can't critical strike and doesn't trigger on structures".
Ofcourse you can do that better. Thx for reading.
