League of Legends Patch 13.1 Overview: LoL Patch 13.1 Changes

Riot Games is kicking off 2023 like any other year: a new season that brings a plethora of changes to flagship multiplayer online battle arena League of Legends, a trend that makes an effort to keep the game fresh since its 2009 inception. Season 13’s pre-season patch, Patch 12.22, was released on November 15, 2022, and introduced the player base to what League of Legends would look like in Season 13. And, as usual for Riot, the preseason patch was used to glean more information from the player base regarding the first official patch of the season: LoL Patch 13.1, which drops on January 11, 2023. 

The majority of changes to League of Legends were introduced in the pre-season patch of 12.22, but what does 13.1, the first patch of the new season based on the calendar year, hold for players? Let’s take a look at what the official beginning of Season 13 will harken for gamers looking to hit Summoner’s Rift.

LoL Patch 13.1: Jax Midscope Update

As per usual in the pre-season, Patch 12.22 introduced many a change to League of Legends, but in the first official patch of 2023, Jax takes center stage in terms of LoL updates. Jax has been around since the inception of League of Legends, and while he has been the subject of minor adjustments in the past, Season 13 marks his first true rework. 

Leap Strike (Q)
  • AP Ratio: 60% >>> removed
Counter Strike (E)
  • Damage: 55-155 (+50% bonus AD) physical damage >> 55-175 + 4% max health (+100% AP) magic damage
  • Damage bonus per attack dodges: 20% of total damage >> 20% of base damage
Grandmaster’s Might (R)
  • Cooldown: 80s >>> 100 – 80s


  • Damage: 100 / 140 / 180 (+70% AP) >>> 100-150 (+60% AP)


  • Bonus Armor: 10 – 40 + 10% bAD and 14 – 22 + 10% bAD per target >>> 25 – 65 + 40% bAD and 15 – 25% + 10% bAD per target
  • Bonus MR is 75% of Armors Value

New Active:

  • Jax swings his lantern around him, dealing 150-350 (+100% AP) magic damage to nearby enemies. If he hits a champion he gains 10-40 (+.1 Bonus AD) Armor and Magic Resist, plus 14-22 (+.1 Bonus AD) per champion hit for the next 8 seconds. During this time the passive damage applies every 2nd attack instead of every 3rd.

Aside from stat changes, Jax’s midscope update for 13.1 features a new active for his Ultimate Ability Grandmaster’s Might, and while the removal of the AP ratio from his Leap Strike is an objective loss, the changes to his Counter Strike even things out in terms of his overall damage spread. Crucially, Jax’s changes – specifically, the addition of an Active to his Ultimate – should afford him more options in early game scenarios while not pushing his late game strength over the edge. 

Abyssal Adjustments in Patch 13.1

Abyssal Mask is getting an update in Season 13 and the change harkens a return of the item’s component from seasons’ past: Catalyst of Aeons. After a two year absence from League of Legends, Catalyst of Aeons will once again be part of Abyssal Mask’s build path in addition to being part of the build path for Rod of Ages, a health-centric mage items that will also be returning to the game after two seasons absent. 

Abyssal Mask
  • Damage to Mana: 8% >>> 7%
  • Mana to Healing: 20% >>> 25%
  • Max Healing per Cast: 15 >>> 20
Catalyst of Aeons
  • Damage to Mana: 8% >>> 7%
  • Mana to Healing: 20% >>> 25%
  • Max Healing per Cast: 15 >>> 20
Rod of Ages
  • Damage to Mana: 8% >>> 7%
  • Mana to Healing: 20% >>> 25%
  • Max Healing per Cast: 15 >>> 20
  • Bonus MS: 25% >>> 35%
  • Bonus MS duration: 2s >>> 3s
  • MS threshhold: 250 >>> 200

League of Legends experienced a massive shift mid-2022 with the Durability Patch (12.10) which saw average champion durability rise to the highest rate in five seasons. The re-introduction of Rod of Ages and the subsequent ripple effects of the item’s existence – particularly the additional re-introduction of Catalyst of Aeons – should result in a meta that will feature control mages but in a far more diverse array than what was present at the 2022 League of Legends World Championship. 

Cosmetic Updates in LoL Patch 13.1

The gameplay updates present in Patch 13.1 aren’t the only changes coming to League of Legends – many champions will be receiving new cosmetic skins to ring in 2023 as well: 

Champions Getting Mythmaker Skins in Patch 13.1

  • Mythmaker Zyra
  • Mythmaker Galio
  • Mythmaker Irelia
  • Mythmaker Sivir
  • Mythmaker Garen
  • Mythmaker Sivir Prestige Edition

Patch 13.1: Champions Getting Lunar Gods Skins

  • Lunar Empress Ashe
  • Lunar Empress Qiyana
  • Lunar Emperor Thresh
  • Lunar Guardian Kha’Zix
  • Lunar Guardian Malphite

Of all of the skins listed above, Mythmaker Irelia will be a legendary skin, and Mythmaker Sivir will serve as The Battle Mistress’ first ever prestige skin.. In addition, Porcelain Lissandra will be returning to the League of Legends shop with a Prestige Edition on 13.1.

Changes to Ranked in League of Legends Season 13: Mid-Season Reset

LoL Patch 13.1 will be the first patch to go live in Riot Games’ new ranked format for League of Legends, which is headlined by a first-ever mid-season ranked reset. There won’t be a second preseason in the middle of the year, and the second half of the year will not see the game change as dramatically as it does every preseason. “We know this is a huge change, but it’s one we think will help keep leek feeling modern and fun while addressing a few of the pain points we’ve seen over the years,” explained Riot Games Head of Events & Global Marketing Chris “Oberon” Roberts in the Season 13 Roundtable with the media earlier in January.

End of season rewards will now be handed out at the end of each of the two ranked “seasons” and good news is coming for the average League of Legends player – the Victorious skin given out to players who finish gold or higher each year will instead be a skin you get at the end of each of the two ranked runs in 2023 regardless of your ranking. That being said, higher ELO finishes will have access to more rewards, and realistically, more sought-after skins, too.
