RP Price Increase

  • As a reminder, starting on August 19 Pacific Time, RP and TFT coin prices will increase in most Riot regions. For more information about the price increase check out our full article here.

Competitive Systems

  • Having a premade duo is a slight advantage, and while current Apex Tier (Masters, Grandmaster, and Challenger) players aren’t able to duo with anyone, the system only works off current rank. With this change, we’re tightening up the Apex Tier restriction to apply to MMR as well.

  • The goal of this is to prevent climbing smurfs from being able to duo queue into Apex Tier. That said, decayed Apex Tier players and the highest skilled Diamond I players may also be impacted by this change.

  • Up until now these players could duo and reliably get into Apex Tier games, which isn't fair when the people they're playing against can't duo. If this change works as expected, we'll evaluate shipping it to the rest of the world with plans to re-evaluate before Season Start.

  • We first rolled out this change back in patch 12.10 on the NA and KR servers as a trial and the results have been positive, so we’re rolling it out to the rest of the world. From now on, players with an MMR correlating to Master or above will no longer be able to duo queue in Ranked Solo/Duo, even if their rank is not Master or higher.

  • Fixed a bug where Yuumi would be unable to use swapped summoner spells from Unsealed Spellbook after using Teleport

  • Fixed a bug that caused Nilah’s Passive - Perfect Synergy to be audible from the Fog of War

  • Fixed a bug that caused Nilah’s Passive - Perfect Synergy to trigger with Ocean Drake’s buff

  • Fixed a bug where Leblanc’s W - Distortion was doing slightly less damage at rank 3 than intended

  • Fixed a bug where Evelynn’s stealth would break after a target she killed entered a Zombie Form and then died again (e.g. Sion’s Passive)

  • Fixed a bug where single target range indicators would sometimes follow enemies through the Fog of War

  • Fixed a bug where Rakan would automatically cast his second E - Battle Dance to an ally after using Flash

  • Fixed a bug where Yone could activate abilities while in his Spirit Form while locked in the blast cone knockback cc
