Braum

Crazy like Devourer does that [slayer-jinx-unamused]

Sated Devourer will make all melee champions strike twice every two attacks, and every four attacks for ranged champion. The second attack doesn't deal damage, but applies on-hit effects, like Braum's passive, Master Yi's true damage, or life steal. Try playing AD Braum; I found it fun!

Ok thank you i didn't knew it
