League of Legends Patch 26.12 reshapes ARAM Mayhem with a major Augment overhaul. You will no longer see Augment Sets, as the mode replaces them with Ability Augments that directly modify your champion’s spells.
The update introduces more than 50 new Augments, including several that carry forward effects from the removed system. You can expect a broader range of spell-focused upgrades and a refreshed pool that changes how you approach each match.
New Augments
Patch 26.12 replaces older systems with a wide range of direct ability upgrades and event-driven effects. You now choose from Prismatic, Gold, and Silver tiers that reshape how your champion functions in ARAM Mayhem. Some options unlock through progression in the Set 2 mini-pass.
Prismatic Tier
These offer the most dramatic changes to your kit and play pattern.
| Augment | Core Effect |
|---|---|
| Chain Reaction | Knockbacks cause secondary knockups and magic damage. Terrain collisions increase duration and damage. Scaling ties to the triggering spell’s cooldown. |
| Dimension Shift | Grants a special Summoner Spell that sends all living units into a separate Realm for 8 seconds, where you gain bonus stats and size. Units cannot target objectives inside. |
| DropBear | You explode on death, stun enemies, and summon Tibbers to chase your killer. Tibbers inherits your augments. |
| Echo Cast | Your chosen spell fires a duplicate toward your cursor and repeats after a delay. |
| En Passant | Periodically marks enemy Vitals. Hitting them deals bonus true damage based on max Health, heals you, and grants movement speed. |
| Hellbent | Build stacks through combat. At maximum stacks, you revive after death with bonus stats and Omnivamp. |
| High Roller | Enemies can drop Stat Anvils on death. |
| Multishot | Quest-based. Landing hits with a specific spell unlocks increasing missile counts. |
| One Trick Pony | Ability Haste applies only to your Ultimate but at higher effectiveness. |
| Overloaded | Using other abilities resets the cooldown of a designated spell. |
| Pin Cushion | Damage during a spell applies Marks that detonate afterward, granting movement and attack speed. |
| Poro Stampede | Feed Poros to unlock and scale a Summoner Spell that launches damaging waves. The first wave knocks up enemies. |
| Quickstep | Casting the linked ability causes you to dash toward your cursor. |
| Rite of Ascension | Takedowns leave behind an Essence. Consuming it blinks you to its location, makes you untargetable briefly, heals you, and refreshes cooldowns. |
| Spellsplit | A spell projectile splits into two upon impact, at max range, or on recast. |
| Spirit Bomb | Healing and shielding build stacks. At maximum, you throw a projectile that heals and shields allies. |
| Squishy Slappy Grab | Periodically latch onto nearby enemies. Your next attack pulls and stuns them while granting you shields. |
| Surge Field | Casting your ultimate creates a moving zone that grants Ability Haste, movement speed, and fires missiles at enemies. |
| Terror | Casting the linked ability fears nearby enemies. Duration scales with cooldown. |
| Titan’s Resolve | Dealing and taking damage builds temporary stacks that grant stats, size, and Tenacity. |
| Tripleshot | Your selected spell targets two additional enemies in front of you. |
Several of these focus on empowering a single ability rather than your full kit. Options like Echo Cast, Spellsplit, and Overloaded reward precision and timing.
Others alter survivability. Hellbent, DropBear, and Rite of Ascension give you second-life mechanics or post-death impact.
Gold Tier
Gold augments deliver strong upgrades without fully redefining your champion.
Ability Interaction and Damage
- Archmage partially refreshes another spell when you cast one.
- BONK! adds bonus damage to empowered attacks or abilities.
- Mercy’s Strike enhances your next basic attack after using a linked spell.
- Ravenous Bind adds damage and healing when you immobilize or ground enemies.
- Rejuvenation restores Health after casting a chosen ability.
Quest-Driven Scaling
- From Downtown tracks long-range snipes and adds delayed explosions on success.
- Pressure Cooker applies a stacking burn and expands its power through a damage quest.
- Pursuit of Haste grants Ability Haste for landing spell hits and scales further via quest progress.
Zone and Terrain Control
- Terrain’d causes terrain you create to damage nearby enemies over time.
- Void Dash leaves a slowing, damaging zone at your dash destination.
- Shark Tempest surrounds your Snowball with damaging sharks that attach on hit.
- Snowblast upgrades Snowball with knockups and increased damage on recast.
On-Death Effects
- Shark Bait lets you move after death and trigger a delayed knockup and missing Health damage.
Economy and Resource Effects
- Combusting Interest converts burn and damage-over-time into gold.
- Yowch, My Coins! causes enemies to drop coins on takedown.
Stat and Scaling Tools
- Tooth Fairy drops collectible Teeth when you burst enemies, granting Lethality and Magic Penetration.
- Warlock Juicebox scales Omnivamp with Ability Power.
- Lil’ Extra Help boosts Attack Range and Attack Speed during a chosen spell.
- Overextender upgrades your Cannon Launcher’s range, speed, and damage.
Team and Positioning Effects
- Pat On The Back grants shields and movement speed when passing allies.
- Wee Woo Wee Woo improves healing and shielding toward low-health allies.
- Our Healing lets you benefit from nearby healing, including doubled effects from enemies.
- Hide on Bush increases damage while empowered by brush.
- Nature is Healing restores Health while inside bushes.
Area and Combat Pressure
- Endless Decimation periodically swings a circular axe for physical damage.
- Porcupine builds stacks when damaged, releasing slowing needles at maximum.
Gold augments encourage repeated interaction. Many reward you for landing specific spells or staying active in skirmishes.
Silver Tier
Silver augments provide smaller but reliable bonuses.
- Adaptive Ward grants stacking Armor or Magic Resist when you strike an enemy champion, based on their primary damage type.
- Don’t Change the Channel supports channeling abilities by improving their reliability and presence in fights.
These options strengthen consistency rather than redefining your strategy.
Design Direction in 26.12
This update emphasizes targeted ability upgrades and quest-based scaling. Several augments directly modify a single spell, reinforcing focused play patterns.
Quest augments now track clear numerical milestones. You unlock incremental rewards rather than receiving all power at once.
The removal of older trait-style systems shifts attention toward individual champion expression. You build around your own kit instead of stacking shared tags.
Practical Impact on Your Play
If you rely on crowd control, options like Chain Reaction, Terror, and Snowblast extend your engage potential.
If you prefer scaling pressure, Multishot, Pressure Cooker, and From Downtown reward repeated hits over time.
If you want survivability, Hellbent, Rite of Ascension, and Titan’s Resolve offer durability through stacking or revival mechanics.
Team-oriented players benefit from Spirit Bomb, Wee Woo Wee Woo, and Pat On The Back.
These augments introduce varied win conditions. You can amplify a single spell, build around repeatable quests, or add post-death influence. Your selection shapes not only your damage output but also your mobility, survivability, and team utility throughout the match.
Removed Augments and Augment Sets
You no longer see Augment Sets in ARAM Mayhem. The developers removed them because bundling effects together narrowed your decision-making and led to repetitive builds. A few former Set bonuses continue as individual picks, but the grouped format is gone.
Several standalone options also leave the pool in Patch 26.12. The following Augments do not appear in the current rotation:
- Buff Buddies, Cerberus, Cheating, Crack Open That Egg
- Demon’s Dance, Executioner, Feel the Burn, Frost Wraith
- Gash, Grandma Chili Oil, Hat on a Hat, Holy Fire
- Keystone Conjurer, Laser Heal, Lightning Strikes
- Poro Blaster, Poro King, Rabble Rousing, Red Envelopes
- Repulsor, Restless Restoration, Self Destruct
- Slow and Steady, Snowball Roulette, Speed Demon
- The Brutalizer, Tormentor, Trailblazer, Trueshot Prodigy
- Twice Thrice, Upgrade Collector, Upgrade Hubris
- Upgrade Mikaels, Upgrade Thornmail, Void Rift
- Watch Out! Cupcake!, Weighted Popoffs, Wind Beneath Blade
