After three weeks of the preseason update, the time has come for Riot Games to introduce another set of major changes to League of Legends with Patch 12.23.

ARAM updates

Frostgates

Frostgates: Frostgates will be present from the beginning of the game and will teleport you directly from your Nexus to your outer tower. Once your first tower is destroyed, the Frostgate will then link to your team’s inhibitor tower where it will then stay for the remainder of the game.

Falling Towers

Tower Rubble: When outer towers are destroyed they will collapse and leave behind a pile of rubble which will be treated as new terrain.

Brush Changes

Brushing Up: There is now one new brush in the middle bottom side of the bridge. The brushes between the outer and inhibitor turrets have also increased in size.

Bridge Repairs

Under Repair: The gaps on the bottom side of the bridge have been filled in and are now traversable

Battle Boost QoL Updates

Not so Fast: Players will no longer be able to activate Battle Boosts within the last 10 seconds of champion select

You’re Welcome: Allies will now be able to tell which player gifted their team a Battle Boost

Rune recommender

“We want it to be easy to get to the fun of League without having to do a ton of research beforehand. So like we added item recommendations to the shop, we’re also adding a rune recommender in champion select! You can access it by hovering or locking in a champion and clicking the new icon next to the edit rune page button. We have a few more planned additions for this feature and will be keeping an eye on your feedback to improve it over the next few patches!

Added the Rune Recommender to champion select for all game modes. These recommendations are tailored for your champion, position, and come with optional summoner spell recommendations as well. Like in-game item recommendations, these will be updated each patch.

All players have a free temporary rune page that the recommender will overwrite in each champion select. To permanently save a recommendation to your collection, you can add it in the post match screen.

The five preset rune pages have been removed.”

Pick order swapping

“Draft strategy is an important part of the game in queues that support drafting, so we want to make it easy for your team to optimize its draft for success. Currently there are a lot of opportunities for things to go wrong for players trying to swap their pick order — you have to communicate in chat with the person you want to swap with, have the champion that the other player wants, and then successfully trade champions before the game starts, all while preparing your rune and summoner loadouts. We’ll be streamlining this process by letting you swap pick order with the press of a button!

In matchmade queues with drafting, during the declaration, ban, and pick phases, you can now press a button next to ally portraits to swap pick order with them. When there is five seconds left in a phase, in-progress order swap requests will be canceled. If your order swap request is declined, you cannot initiate another request with that player.

Champion swapping during the preparation phase is now initiated by clicking on the allied champion’s portrait instead of a button next to the portrait.

Miscellaneous champion select font and text changes for consistency.”

Champ select anonymity

“We’ve heard feedback that with the only difference between ally’s names in champion select being the numbers 1 through 5, it can be difficult to tell who’s speaking, particularly when a lot of people are talking at the same time. So now you all get code names!

Ally one -> Ally five have been renamed to Gromp, Murk Wolf, Raptor, Krug, and Scuttle Crab for improved clarity around who is speaking in champion select chat.”

Behavioral Systems

“End of Season Honor rewards including the new Honor level five Malzahar skin reward will be granted according to your Honor level at the End of Season.

The ARAM AFK threshold has been changed to 120 seconds from 90 seconds.”

Bug fixes and quality-of-life changes

Champ select favoriting improvements

“Improving usability around favoriting champions so that you can find them faster in champion select. As a reminder, you can right click champions in champion select to favorite them for a specific role!

In champion select, ‘Sort by Favorites’ is the default sorting option. Note: The fallback option is ‘Sort by Name’ so a player who does not have any favorites selected will still have the same experience.

A player’s selection for “Sort by” preference is saved between champion selects.”
