SATED DEVOURER I CHOSE YOU
simple. Fix it, it's dumb everything about what you did to it is dumb. Shyvanna with sated + botrk when E aa Q'd does 40% (5botrk procs) current hp in physical 10% max hp in physical (botrk active) 10% max hp (5 shyv e procs) in magic damage 300 flat magic damage (5 60damage devourer procs) and she has a 300 something magic damage ult gap close 10581358105810 movespeed a redsmite ticking on you and a red buff ticking on you... explain your logic of balance?
riot logic it's only balanced when shyvanna can e aa q and take someone that's full tank to 300 hp with 2 items.
Give it a completely new passive there is no way you can balance doubling onhit effects be real rework it again.
