The first Ranked split of 2019 ends this Sunday night at 23:59 AEST for OCE players.
This means you have until this time to earn your Ranked Summoner Icon, Armour Upgrade, and Emote rewards before the second split starts and a new set of rewards becomes available to earn. Once the split ends, these rewards are unobtainable so make sure to get your last few ranked wins in before it's too late!
To check your current progress on split rewards, check out the Ranked tab under your Profile in the League client.
