Rito, Rek'Sai needs a hidden passive with the Scuttle Crab

Seriously, I don't know why Rito hasn't already done this. Preferably, there could be a special taunt or something whenever Rek'Sai slays the crab.

But, since all Rek'Sai does is growl (obviously a bit problematic), we could have something a little more easier to make by Riot.

Just make like a little buff like Caitlyn, Vi and Jinx have, counting how many Scuttle Crabs Rek'Sai has killed. The count could be something like Brethren Slain or something idk. RITO PlS
