LoL Arena Patch 13.15 notes | All LoL Arena buffs, nerfs, and changes in Patch 13.16

The doors may be swinging shut on the League of Legends Arena playlist soon, but that won’t stop Riot Games from tinkering with the 2v2v2v2 game mode’s flourishing metagame right up to closing time⁠⁠⁠—and that’s exactly what the developers are doing in August’s next update, which is quite the whopper.

When will League Arena Patch 13.16 go live?

League Arena updates are always bundled into the League-proper patches, which means these changes will be going live on Wednesday, Aug. 16.

Riot likes to make sure the patch staging times are staggered a little to avoid any problematic hitches in rollouts, so it’s region-specific. My updates (I play in Australia) always go live around 10am AEST. For all the other major League regions, here are key patching times:

• 3am PT (NA)
• 5am GMT (EU West)
• 3am CET (EU North East)
• 8am KR (Korea)

Here’s a countdown to these changes releasing:

Expect several hours of League server downtime on that date.

What’s changing in League Arena in Patch 13.16?

The next League Arena patch is going to ship out a whopping 21 champion changes (divided between 18 buffs and three nerfs) and will also include tweaks for 14 Augments and at least a dozen items.

Riot leans toward buffs over nerfs

In regards to buffs, Riot seems to be leaning toward giving popular characters who haven’t really found their footing in Arena a little boost, including Akali (who was buffed last patch too), Lee Sin, Xerath, and Ezreal. Other characters like Nidalee, LeBlanc, Gragas, and Ekko are also in line to get Patch 13.16 buffs.

Three champions are heading the other way: Fiora, Warwick, and Cassiopeia, all of whom I flagged as powerful picks in my League Arena rankings recently.

More power for lagging Augments

Riot is trying to bring a few of the League Arena Augments up a tier in the mode’s waning days, with big boosts for flagging picks like Tormentor, Blunt Force, From Beginning to End, and Combo Master. Of the nine Augments getting buffs in Patch 13.16, only Phenomenal Evil and First Aid Kit got changes that altered defensive capabilities⁠—they are getting cooldown and shields respectively.

On the other side of the coin, most of the Augments being nerfed, including Tank It or Leave It, Ok Boomerang, and Spirit Link, are all tied to damage.

Stats the name of the game for item changes

In the item department, 10 items are getting buffs, while just five are being nerfed. There’s a specific focus Riot is placing on these buyable boosts in League Arena too, with more than half the changes targetting underlying stats, ranging from maximum health, armor, and magic resist to base damage and haste.

I’ve put together a full list of changes below. Remember, these are still being tested on the League PBE, so not every single one may land on live servers.
