Hi friends. It’s just about that time to wake up, ‘cause September’s coming to an end.
This patch is on the lighter side, with most changes concentrated on tuning champion scaling as games progress. Big ticket items include a helping hand
 to a certain blue mage by giving him more damage to play with, along with tempering down Karthus who’s been a nightmare in the bot lane. Apart from champion changes, Worlds 2020 Clash is on its way to you! It's time to be the hero and to kiss
 away the pain. And to win a cool trophy.
On a clerical note, upon logging in this patch, you’ll be presented with the new Code of Conduct. This agreement helps us define the behaviors we expect of you as a player.
So get
 on the rift and that future boom boom boom. You gotta get that.

Champions
[Aatrox](http://gameinfo.na.leagueoflegends.com/en/game-info/champions/aatrox/)
R self-healing increased later.
Aatrox wants to step into his full potential as the unkillable DPS monster, so we’re helping him harness his darkin power by curbing some of his mid- to late-game falloff. Hopefully now this warrior demon won’t fall flat in late game teamfights.
