Infinite Recursion

Infinite Recursion lets Karthus cycle Requiem absurdly fast and constantly pressure team HP bars.

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

Morgana's Q and W cooldowns overlap heavily. With Archmage's Q-reduces-W / W-reduces-Q loop, you can perma-root and burn enemies. Only ~80 ability haste needed for infinite QW — high tolerance, miserable to play against.

Ult has high AP scaling and deals magic damage.

Build around Fey Magic + Ornn's first R hit. Fey Magic procs Brittle 4 times on first ult — Brittle's 18% max-HP magic damage stacks four ways for 72% max HP, then magic pen + amp items finish the kill. Forge: ability haste > magic pen. At ~500 haste, Fey Magic is ~15s CD and ult is ~16s — every fight is a nuke. Build straight magic pen + damage amp.

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

Ethereal Weapon makes abilities trigger item effects — feels like old-school Zed.

Ezreal's passive at max stacks gives 50% attack speed, which Purist + Caster converts to 200+ ability haste. Q's hit-reduces-CD means Q has practically no cooldown late, and R refreshes in under 10s. Late, full-screen ult every 10 seconds = enormous pressure.

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

Build Rylai's so E becomes AoE hard CC, which procs Cruelty.

Always Rylai's — E roots normally and stuns when empowered. Both forms of CC stack Slap Around, and AP piles on fast. Even basic E procs the hex without needing the upgrade.

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

Leona QER are all CC — high frequency Cruelty procs.

With 4-stack Shrink Engine (3x multiplier), all scaling hexes give 3x value. Combined with Soul Eater for HP and Infinite Recursion for haste, you can hit 110k HP and 3000 AD — pure stat monster. Heavily reliant on stacking scaling hexes; survive early to bank the snowball.

Stack Shrink Engine synergies — Nasus already gets bonus per stack; on a TF Mobi Q stacks 24 normally, 36 with two, 48 with three, 72 with four Shrink Engines.

Stack Shrink Engine to boost haste, infinite AE, max mobility.

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

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

Archmage + ~190 haste enables infinite WQ knockup. Don't cast E — just WQ on loop.

Very ability-reliant — prioritize stacking ability haste.

100+ haste + Archmage = infinite Q.

Shrink Engine massively cuts R's CD. Stack Soul Eater for HP, and Triple-Stack Dragon bond × 2.5x means hex and champ stacks both ramp absurdly fast. R CD drops to ~10s. Triple-Stack Dragon means one feast = 3 stacks. Since E's % damage scales with R stacks, late damage is huge.

Stack CDR and plant shrooms everywhere.

Once CDR is high, infinite E permanently jails enemies.

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.

Hubris stacks too slowly early; pair with Collector for pure lifesteal — works for sneaky players. Hide early until IE comes online; pre-level-6 use kills to ramp, otherwise late falls off.

Practiced in real games — see lots of squishies on the enemy team, take Hubris. Hubris → Collector → Profane Hydra.

Core: Goliath + Slap Around + Soul Eater + Infinite Recursion. Cheese a couple waves.

Random hex luck = cruise game; we had a 4v5 AFK and still rolled. Shrink Engine's CDR and MS fit Hecarim perfectly; Dropkick deletes squishies cleanly; Infinite Recursion = huge CDR; Q becomes electric fan; Soul Eater for Triple-Stack Dragon bond + HP; Hubris ramps fast and HP boosts Dropkick's execute threshold.

Cruelty + Archmage = infinite pillar build. Archmage + Cruelty, minimize CDs for endless pillars.

Cut R CD. Just go.

Pillar emperor.

Stack ult-CDR to the extreme. Not particularly strong, but extremely satisfying.

Stack CDR to the limit and spam pillars with main-E for max meme value.

Squishy poke duels — without Executioner, take CDR. Save W for assassin/bruiser face-divers.
