Arena just received its most ambitious redesign since the mode launched. Season 2 arrives with three structural pillars that change how the mode plays at a fundamental level: a rotating Events system, a new Augment Levels mechanic that lets you amplify your strongest augments, and two maps — one brand new, one significantly reworked. Here is everything you need to know before you queue.
Four Events, Four Ways to Play
Events are rotating limited-time rule variants that change the match format from week to week. Think of them as mini-modes layered inside Arena. There are four in the current rotation, and each one rewards a different approach to champion selection and augment drafting.
No Event — The Learning Window
Each patch cycle opens with a No Event period intentionally. Riot uses this window to let players get comfortable with new maps and augment pools before additional format complexity layers on top. Use this time to master the Augment Levels system before the rotation changes.
3x6 — Three Players, Six Teams
The most dramatic format shift: 3x6 expands each team from two to three players while running six teams simultaneously. For the first time, you can run a proper ADC-support-frontline composition in Arena. Champions that previously struggled without protection — Kog'Maw, Jinx, Aphelios — become genuinely viable. Engage supports like Leona and Amumu shift from wasted picks into essential team anchors.
Bravery — Random Selection, Real Strategy
Bravery randomizes champion assignment across the lobby with curated fallback options available if a pick simply cannot function in the mode. The correct mindset for Bravery is adaptation rather than frustration — focus on augment selection and combat positioning fundamentals rather than champion-specific mastery. A wide champion pool is the best preparation.
Swift Arena — Read Your Opponents
Swift Arena runs a 2v4 structure at accelerated pace with repeated opponent matchups across rounds. Because you face the same teams multiple times, opponent-reading becomes a genuine competitive skill. Track what their build is doing between rounds and adjust your augment selection accordingly. A poke setup early should transition to sustain if they adapt correctly.
Petricite Grove — A Brand New Arena
Petricite Grove is the first truly new Arena map since the mode launched. Set in the Demacia countryside, the map features larger walls that provide genuine cover and scattered mining bombs throughout the terrain. These bombs detonate when an immobilized champion stands near them — making hard CC abilities like Jarvan IV's Cataclysm, Lux's Light Binding, and Nautilus's Dredge Line trigger explosive bonus damage on detonation.
Poke and kiting champions thrive on Petricite Grove thanks to extended sight lines and wall cover. Zeri, Jinx, and Ezreal find angles to sustain harassment from positions that the original Arena maps never permitted.
Ancestral Woods — A Smarter Small Map
Ancestral Woods retained its identity as Arena's most compact map but received significant structural updates. The central Power Flower has been removed and replaced with two systems: multiple flowers now ring the perimeter requiring active movement to contest, and the Bulwark Blossom at the center provides a large heal and shield when claimed — scaling up when your team is outnumbered to create natural comeback potential.
New brush sections and terrain features create extended engagement windows. Mobile champions like Ahri, Ekko, and Fizz exploit the terrain for cat-and-mouse sequences, and the map now rewards evasion over pure front-loaded burst damage.
Augment Levels — The Core System Change
Before Season 2, augment drafting was purely additive — you added new ones each round. Now you can level existing augments to amplify their base effect and unlock new bonus behavior at higher tiers. This changes how you evaluate augments from round one. A mid-tier augment with strong level-up potential can outperform a silver augment you would never invest additional points into.
Augment offering frequency has been increased to support the leveling system. Round 8 introduces the Crafting Round — a dedicated window to add a new augment slot or remove an existing one entirely. Use it as a pivot if your composition is not coming together, or to stack a sixth augment on a build that is already performing.
New Augments Worth Building Around
- Wild Fire: Auto-casts a bouncing fireball between champions. Bounce count increases with each level — extremely strong on mages and poke champions who want passive damage generation.
- Scavenger: Grants you augments from opponents you defeat, but restricts future offerings to level-ups only. High risk with a high power ceiling — best on aggressive early-game picks.
- Magical Girl: Deploys a protective falling star with knockback and a rain of damage on impact. Reliable defensive tool for squishier picks who need survivability options.
- Transmute: Silver: Instantly fills remaining augment slots with silver-tier augments. Useful for fast early power spikes when you want volume over quality.
Guests of Honor — Key New Recruits
Over 20 new Guests of Honor join Arena Season 2 while previous recruits are temporarily disabled. These are the standout additions worth drafting around:
- Kayle (Divine Ascent): Prevents your team from losing health on the next defeat — a safety valve for difficult matchups where elimination risk is high.
- Ornn (The Forge God): Unlocks a rotating prismatic item shop, opening access to items not normally available in Arena. Changes your entire itemization approach.
- Nocturne (Darkness): Creates visibility-blocking zones across the arena — completely disrupts standard positioning and benefits assassins and ambush compositions.
- Fiddlesticks (A Harmless Scarecrow): Attaches blessings or curses to all augment offers — high variance gameplay that rewards risk tolerance.
- Yone (Inner Demon): Forces a team vote between Demon and Demon Hunter alliance — adds a social coordination layer to champion selection.

Build Strategy by Event Mode
3x6 Build Priority
With three players per team, sustained damage and healing compositions dominate. Build Warmog's Armor on frontliners for healing during safe zone periods. Pair a protective Guest of Honor like Kayle or Ornn with two damage dealers. Assassins spike hard in 3x6 — Zed and Talon can eliminate an isolated target before the full team responds.
Swift Arena Build Priority
Fast power spikes outperform three-item scaling builds in Swift Arena's compressed round structure. Prioritize mythics that activate early — Trinity Force, Rabadon's Deathcap, and Luden's Tempest deliver value in two purchases. Repeated opponent matchups reward situational augment pivots: if they run heavy healing, invest in Grievous Wounds on your first augment pass.
Petricite Grove Pick Priority
CC-heavy champions convert mining bombs into free burst damage. Lux, Jarvan IV, Nautilus, and Zac perform above their standard Arena tier on this map. Mages and long-range ADCs benefit from extended sight lines and wall cover for sustained harassment without committing to close-range trades.

Arena Season 2 is a genuine ground-up redesign rather than a cosmetic update. The Events rotation prevents any single strategy from dominating for long, Augment Levels reward build-crafting knowledge across a game, and the new maps create distinct mechanical demands each session. Whether you are a returning Arena player or trying the mode for the first time, Season 2 is the strongest and most replayable version of Arena yet.
