The PBE landing page has received small updates: the chat and right hand corner (notifications, friends list, buttons) now fit the new UI. The full list of champions and skins that will be on sale this month is out. Below is the long list, or if you want to come back and check daily, I will be posting the full list on the League of Legends page. Just head on over to the top menus of this website under League of Legends and click August Sales (under Champion & Skin Sale). And lastly, there were a few balance changes to champions like Morgana, Zed and Rengar.
**Poro summoner icons have been added on PBE.
