League of Legends Arena mode is coming through with its very own update, Patch 13.16, with a range of changes aimed to bring more of the roster in line with one another, bringing buffs and nerfs to see it through.

Arena has been a godsend for League of Legends players, giving the 14-year-old MOBA a breath of fresh air. Riot is looking to continue balancing with the mode, despite it being removed at the end of the Soul Fighter’s event.

If you’re looking to keep up with the latest updates on everything happening in the newest mode, here are the patch notes for Arena in League of Legends Patch 13.16.

Bunch of Buffs

Plenty of champions, items, and augments are receiving buffs in Patch 13.16. These include buffs to AP assassins like Ekko, Akali, and Evelynn, buffs to healing and shielding augments, and much more.

Numerous Nerfs

Like the buffs, there are plenty of nerfs coming to champions, items, and augments deemed slightly too powerful in the Arena. Champions like Fiora, Warwick, and Cassiopeia are getting their power tuned down a bit in Patch 13.16.
