League of Legends Arena Patch 13.15 notes: Buffs and Nerfs, Augments, Cameo changes, and more

Riot announced all of the Arena changes that will be included in League of Legends patch 13.15.

Riot officially released the newest League of Legends game mode, Arena, a few weeks ago. It is played in a 2v2v2v2 form on a separate map with many new features to the game like Augments, Cameo, and more.

Arena varies fundamentally from Summoner’s Rift or ordinary League of Legends, therefore Riot must make certain arena-specific tweaks. During the PBE, they already made several adjustments. Furthermore, Riot hotfixed this mode twice when it was first released.

However, Riot has revealed that many more Arena-exclusive improvements are coming to the game with patch 13.15. Here is a list of all of them.
