League of Legends Arena 2v2v2v2 returns with patch 13.24: All changes coming with the new permanent game mode

The 2v2v2v2 Arena has finally returned with League of Legends patch 13.24, and this time around it’s going to be a permanent game mode in the MOBA. However, with its return, Riot has changed some features of the mode quite a bit and also introduced a series of balance tweaks to both champions and items.

Some of the biggest updates to the game mode will be the addition of Hexgates to all four Arenas, along with the feature to revive dead teammates.

Below is the list of all the changes that have made their way to the 2v2v2v2 Arena with League of Legends patch 13.24.

League of Legends Arena 2v2v2v2 changes

1) Arena Returns

A huge amount of class and individual champion balance changes.
Hexgates have been added to all four Arenas!
Death is not the end! After a delay, you can revive your dead teammate by standing on their body!
Riot has removed the Naafiri, Samira, Shaco, Virgo, Lux, Evelynn, and Jhin cameos, and we've added Sylas and Thresh cameos!
4 new items!
60 new Augments!

2) Gameplay Updates

Hexgates

Hexgates have been added to each of the 4 Rings of Wrath. They work just like they do on Hextech Rift and Howling Abyss and have a 7 second cooldown.

Downed State/Reviving

When a champion dies for the first time each round, they become downed for 11-8 seconds (based on round number), after which they become revivable. If an ally stands near a revivable ally for 3 seconds, they are resurrected and healed by their ally for 150+75 per level.
Revive duration is cumulative. If you spend 1 second near your Downed ally, then leave and come back, they will only take 2 seconds to Revive.
Revive duration is decreased based on the reviver’s Heal/Shield Power, and also decreased based on how much less team health the reviver has than the enemy team.
When you are revived, you become Invulnerable, Untargetable, and unable to attack/cast for 0.75 seconds. You will also gain 30% damage reduction, 75% Move Speed, and 50% Tenacity decaying over 3 seconds (or 2.25 seconds after the invulnerability ends).
In order to revive an ally, the ally must not be reviving with another effect or ability such as Zilean’s R, Zac’s Passive, or Guardian Angel.

Cameos

The following Cameos have been removed: Naafiri. Samira, Shaco, Viego, Lux, Evelynn, and Jhin
The following Cameos have been added: Sylas (At the start of the round, Sylas replaces Summoner Flee with a one-use random Ultimate) and Thresh (Thresh will occasionally throw out a Lantern. The Lantern continuously Shields and can be selected to be pulled to Thresh).

3) New Items

Sword of the Blossoming Dawn: 40 Ability Power, 200 Health, 15% Heal and Shield Power, 15 Ability Haste. Passive Effervescence: Gain 1.2% Attack Speed for every 1% Heal and Shield Power you have.

Wordless Promise: 60 Ability Power, 15% Heal and Shield Power, 25 Ability Haste. Active - Promise: Make a Promise to an ally (90 second Cooldown). Passive Promise: Gain 20% of your Promised ally's Ability Power, and grant your Promised ally 20% of your Ability Haste.

4) Augment Updates

Once two champions possess the same Augment, that Augment is removed from the pool.
60 Augments have been added to the Augment Pool! While we could share them all here, it’s more fun to enjoy exploring and experiencing them live. GLHF!
