Arena v2 was shipped to PBE today even though it’s not enabled yet. Naturally all of this is extremely subject to change in the future.

 

Cameos:

returning cameos:

• Sett
• Pyke
• Gwen

removed cameos:

• Evelynn
• Jhin
• Lux
• Naafiri
• Samira
• Shaco
• Viego

 

new cameos:

Sylas, “Great Mage Rebellion”

Sylas has broken the chains granting you access to a powerful Ultimate spell. Once cast, your spell will return to normal.

[this appears to be pulling straight from Ultimate Spellbook data, which might mean we might see Ultimate Spellbook come back somewhat soon since they would have had to make sure those spells all still work in order to repurpose them for this mode]

Thresh, “Midnight Express”

Thresh roams the map tossing his Lantern to the furthest champion, granting a nearby champion with the lowest Health a small Shield and allowing anyone to click it and take the Midnight Express to Thresh’s location. If a single champion is downed inside the Ring of Fire, Thresh will instead move to the downed player’s location and throw his Lantern to their ally. When a player is dead and their ally is outnumbered, Thresh will always throw his Lantern to the that ally.

 

datamined cameos (these were probably scrapped):

Zilean [placeholder title is just “Zilean”]

Zilean will cast Timewarp on every player increasing their AS, MS, AH, Tenacity, and HPregen for each time it is cast.

Draven, “4v4!”

Pair up with another team to take down the other four players!

 

Items:

TO BE ABSOLUTELY CLEAR THESE ARE ARENA ITEMS NOT PRESEASON ITEMS

No items appear to have been outright deleted, although figuring out if they’re disabled or not is a bit annoying so I’m not entirely sure that nothing was removed.

Some of these appear to be scrapped quest combo items (only Wooglet’s seems to have stuck around).

Sword of the Blossoming Dawn

• 40 AP
• 200 HP
• 15% HSP
• 15 AH

Effervescence: Gain +1.2% AS for every 1% HSP you have.

Promise: Gain 15% of your Promised ally’s Ability Power, and grant your Promised ally 15% of your Ability Haste. Champions can only be linked by one Wordless Promise at a time.

[there is also a data value implying this effect might only persist while you are within 1250 range of each other]

Hellfire Hatchet

• 55 AD
• 16 lethality
• 15% ovamp

Char: On-Hit, heal for 2% Target Current Health and apply a Burn that deals (16% bAD +10% AP) +3% Target Missing Health physical damage per second for 4 seconds.

• 20 lethality

Death and Taxes: Dealing damage that would leave an enemy champion below 7% health executes them. Champion kills grant an additional 250 gold and heal you for 30% of the target’s max health.

Adaptive Helm (appears to be disabled)

• 800 HP
• 50 AR
• 100 MR
• 10 AH

Voidborn Resilience: For each second in champion combat gain a stack granting 2 Armor and Magic Resist, up to 8 stacks max. At max stacks become empowered, instantly draining enemies around you for (100 +10% bHP) magic damage (healing you for the same amount), and increasing your bonus resists by 20% until end of combat. The drain repeats every 4s as long as you stay in combat.

Absorb: Taking magic damage from enemy Champions grants a stack of Steadfast (max 8) for 7 seconds. Enemy Immobilizing effects grant an additional 2 stacks. One spell can add a new stack of Steadfast every 1 second.

Dissipate: While at 8 stacks of Steadfast, gain 50 Magic Resist and 14% increased Move Speed.

[a mix of Jak’Sho and Force of Nature, perhaps a scrapped quest augment for collecting them, similar to Wooglet’s?]

Obsidian Cleaver (appears to be disabled)

• 70 AD
• 700 HP
• 40 AH

Carve: Dealing physical damage to a champion applies a stack of 7% Armor reduction for 6 seconds (max 42% Armor reduction).

• 40% AS
• 25 AH
• 30% LS

Cleave: Attacks and Abilities deal (40% tAD +24% AP if melee, 20% tAD +12% AP if ranged) physical damage to other enemies within 600 units of the target hit and triggering on-hit effects.

Spellblade: After using an ability, your next attack is enhanced with an additional (66% AP +320% bonus AD) + 4% of the target’s max HP physical damage, restores (39.6% AP +192% bonus AD) Mana, and creates a frost field for 2.5 seconds. Enemies that move across the field are slowed by 30%. Your primary target is crippled, applying a 100% stronger slow on them and reducing their damage by 10% against you for 2.5 seconds. 1s cooldown. If the target is a champion, also heal for 65% of the premitigation damage.

[appears to be a mix of every Spellblade item, perhaps a scrapped quest augment for collecting them, similar to Wooglet’s?]

 

Augments:

Unless stated otherwise, any previous augment not listed is either unchanged or is only a numbers change.

Also worth noting that there’s a new series of “Curse” augments that synergize with each other but are spread out across the different rarities.

disabled augments:

• Midnight Express: automatically throw a lantern to your ally. [repurposed by the Thresh cameo]
• Zhonya’s Epiphany: gain the Zhonya’s summoner spell.
• Cannon Fodder: enter combat launching from a cannon.
• Buckle Up: spawn a battle sled at start of combat.
• Evocation: gain summoner spell that channels to restore health and mana.
• Windspeaker’s Blessing: healing and shielding increases the targets resists.
• Virtuous Cycle: your healing grants extra shielding and your shielding grants extra healing.

 

modified augments:

Quantum Computing: automatically slash in a circle around you

Looks like the tooltip was updated in one spot (but not all of them) to mention that this slash also heals you. Old clips show that this healing was already in place previously. There’s still no actual values for the damage or healing available to the tooltip however.

Phenomenal Evil: permanently gain 1 AP on ability hits.

Summoner’s Roulette

Replace your Summoner spells with random ones. When you use a Summoner Spell in combat, replace it with another random one on a 6 second Cooldown.

 

Champions:

There’s a ton of champion-specific balance changes, but they aren’t all that interesting and this post is already obnoxiously long and pushing the bounds of usability for this platform.

Only real item of note is that the “this spell has +/- X ability haste” changes have been reworked into overriding the cooldown values directly. This is part of a new system they added a few patches ago to make mode-specific cooldown changes significantly easier to implement, and the previous system was really just a necessary workaround because they didn’t have a nicer way of doing it yet.
