Eureka ARAM: Mayhem combos

Aurora's passive triple-ring deals % max-HP magic damage — at 800 AP it hits 20%+ max HP. Ethereal Weapon multi-procs it for insane burst that pure tanks can't survive. Forge: AP > magic pen. Always grab Ethereal Weapon, then prioritize CDR and MS hexes.

W and E have very short CDs and Archmage chains them — W reduces E, E reduces W — full-screen bullet hell. Needs 200+ haste; pair with haste hexes.

Use Infernal Conduit's CDR refund — stack 160+ haste with runes/items, and W on 2+ enemies refreshes seamlessly = infinite W. W must hit at least 2 enemies for the loop; early on, stack basic haste via Lost Chapter and Blasting Wand.

With Archmage's bond, Q reduces W's CD while W's mechanic reduces Q. At 110 ability haste, infinite QW. Just alternate QW endlessly and chain-control to death.

Very ability-reliant — prioritize stacking ability haste.

After casting R, press R again to control the bear — Killing Time still triggers. Stack CDR for seamless bear chains and Killing Time uptime; stored damage explodes as true damage, huge amp.

Mystic Punch infinite knockup build.

Combine Archmage with ~300 ability haste for infinite R.

High damage, good tolerance, long R cooldown.

At 500 ability haste, R has only a 12s cooldown.

Classic Fizz — one-shot low-HP enemies, then Zhonya's or Fey Magic E to bail. Fey Magic is the key tech; haste is your top priority for high uptime.

Mystic Punch's CDR + Dusk and Dawn enables infinite Q.

AP Irelia — damage from EWR.

Play this when the enemy lineup is squishy. RQ for explosive damage.

Pure AP is squishy and damage-light — go half-tank and stack CDR for faster passive procs. Use R to clear waves.

AP burst. Standard build, any of the listed runes work.

Ethereal Weapon procs Lux's passive — E into multiple enemies and you can detonate the passive mark on all of them.

Use hexes to slash R's CD. Take any R-CDR hex; Ultimate Revolution is even better.

Void Rift is magic damage, so it fits AP champions with high magic pen — % magic pen amplifies it, and Pridestalker's ability damage procs it many times. Forge: magic pen > AP > MS.

Use Q for huge damage. Standard AP build, no heavy hex reliance; with Cruelty, build Stormsurge first.

Infinite raining bullets.

100+ haste + Archmage = infinite Q.

Ascended Ryze. Operation + luck = win.

Use W's CC and damage to torture enemies. Once W-CDR + Eureka spawn, it's good to go.

Syndra's QE triggers Slap Around twice; hitting multiple enemies stacks it extra fast.

Stack CDR and plant shrooms everywhere.

R deals % magic damage — level 3 base is 30%, +16% at 800 AP, and 3500 AP hits 100% max HP.

Pairs with passive for massive AP and ability haste.

Once CDR is high, infinite E permanently jails enemies.

Ziggs's CDs are already short — stack haste and play it like URF.

Eureka is another excellent Karthus spike, giving him frequent ult pressure and strong snowball tempo.

After picking Eureka, step back after casting E so Eureka triggers — otherwise it doesn't proc.

Damage is huge but fragile.

AP build amps Twitch's passive true damage and E burst; W's huge slow locks enemies down. Slows don't stack — no Rylai's. Twitch's passive can't proc Liandry's or Ethereal Weapon — don't pick those.

Stack CDR to the extreme and chain infinite walls with W. Just for fun.

Meme build — Sejuani's kit scales hard with AP, full combo deletes squishies. Don't ask what happens when it doesn't kill — it's a meme. Weaker than tank Sej, but fun.
