Lost to a Kalista with Devourers in bot lane.

You lost to someone with Devourer in lane? Not even able to make it Sated or stack period unless they get 15 kills or 30 assists(or a mix).

You must be really bad.

So you lost to a champ without a key summoner spell (taking smite over flash or heal)? You lost to a champ that had a horrid early lanning phase since they were building a jungle item? Chances are you deserved to.

devourer has significant on hit magic damage in contrast to the physical damage that could be real punishing with the on hit damage and she jumps out of range before the damage can cause minion agro and double stacks for sated could really punish for kalista expecially if she went challenger for the true damage

you don't even need to sate it for it to be efficient, you get 50%as and 30 "ad" for only 2250 g, with the addition of a slow (smite). pretty strong on kalista
