Olaf

Hold axe range rather than walking straight through the lane, and use Undertow to make Ahri spend Spirit Rush charges defensively. Do not ult just for Charm unless you can immediately keep picking up axes and stay on top of her. Commit after one or two dashes are gone, then chain Undertow slows into Reckless Swing.

Later Finished builds make Ahri harder to pin in open space, while Olaf remains better if the fight starts in a side lane or jungle corridor. In teamfights, Ragnarok lets Olaf ignore Charm and dive her backline, but he must not burn the whole ult chasing Spirit Rush into fog.

• •Stand off the minion line so Orb of Deception cannot hit both directions for free.
• •Charm is less scary during Ragnarok, but the time lost before you ult still matters.
• •Force Spirit Rush sideways with Undertow angles, then cut off her return path.
• •If she uses Spirit Rush aggressively, turn immediately before the second dash resets the spacing.

Fight her outside the shroud edge and keep axes landing where you can retrieve them without walking blind through the smoke. Save Ragnarok for the moment she commits with Shadow Dance chains, not for the first Mark of the Assassin. Once she is visible and in melee, Reckless Swing trades better than her rotation.

Later Olaf keeps the side-lane advantage if he has enough durability to live through her first mark proc. In teamfights Akali is better at reaching carries, so Olaf should either reveal her path with axes or force her to duel him before she gets a reset-style cleanup.

• •Do not chase deep into Twilight Shroud without an axe already placed through it.
• •If Mark of the Assassin is on you, back up until the proc window is awkward for her.
• •Ragnarok denies any peel around her, but it does not reveal her in shroud.
• •Low-health Olaf is dangerous here because Berserker Rage and Vicious Strikes punish her all-in.

Let Alistar use Pulverize or Headbutt for spacing, then re-enter with Undertow instead of chasing during his full combo. If he ults, keep him slowed and wait out the damage reduction before spending repeated Reckless Swings. Ragnarok is mainly to stop his crowd control from buying escape time.

Later Olaf wins the side lane unless Alistar is only trying to disengage. In teamfights, Alistar's peel is valuable, so Olaf should ult through Headbutt/Pulverize and attack higher-value targets rather than spending the whole fight on the cow.

• •Do not dump your full damage into Unbreakable Will unless he is already trapped.
• •Ragnarok turns his combo from peel into mostly displacement timing.
• •Axe behind him after Headbutt so the chase resumes immediately.
• •If he is support-built, the duel is slow but heavily Olaf-favored.

Do not stand still trading autos forever; use Undertow resets to keep him slowed while spacing out his sustained aura damage when needed. Ragnarok through Bandage Toss or Curse of the Sad Mummy if those spells would stop your kill window. Once his major crowd control is spent, stay in melee and force repeated Reckless Swing trades.

Later Olaf still wins most isolated side-lane duels, especially if Amumu is built as a teamfight tank. In 5v5s Amumu's ultimate is more important than the duel, so Olaf should either force Ragnarok before the engage lands or bypass him to pressure carries.

• •Sidestep Bandage Toss before ulting if possible; saving Ragnarok gives you a cleaner kill.
• •Short resets outside Despair range matter more as both health bars get larger.
• •Do not let Curse of the Sad Mummy freeze you while his team arrives.
• •Amumu's armor reduction does not stop Reckless Swing true damage.

Approach from angles where a wall cannot fully cut you off, and force Flash Frost before turning Ragnarok on. Keep Undertow aimed past her so every pickup advances your chase. Commit only when she has used wall or stun, because killing the egg after a bad chase is usually impossible.

Later Anivia becomes much better in teamfights and around terrain, while Olaf only threatens her from flank angles or in long lanes without a wall trap. In side lane Olaf can win if he starts close and has Ragnarok for the first control chain, but Anivia's egg often turns a narrow kill into a reset for her team.

• •Do not ult before Crystallize unless you are already beside her.
• •Throw axes through the egg's escape side so the second kill is possible.
• •Glacial Storm makes straight-line chasing too expensive without axe hits.
• •Banshee's Veil blocking Flash Frost can create the one real engage window.

Track Pyromania stacks and do not give her a free stun combo before you are ready to ult forward. If she holds stun, Ragnarok as you commit so Tibbers cannot lock you out of lifesteal and Reckless Swing. After the burst is spent, keep axes tight and finish quickly before a second spell rotation.

Later Annie's teamfight engage scales better than her duel, while Olaf's job is to make that stun fail by ulting through it. In side lane he can kill her from close range, but if she sees him coming with Flash and stun ready the fight remains dangerous.

• •Count Pyromania before walking into her cast range.
• •Do not waste autos into Molten Shield if Tibbers burst is still available and you cannot finish.
• •Ragnarok should cover the stun, not the cleanup after you are already low.
• •A spell shield against her first stun can decide the duel outright.

Stay at Undertow range until an axe lands, then chase through the pickup path rather than running directly at her. Save Ragnarok for Enchanted Crystal Arrow or the moment you are in sustained Frost Shot range and can force melee. Once you touch her, keep axes short so she cannot rebuild space between autos.

Later Olaf remains favored in the side lane if he can force the fight without walking through a full lane of slows. Ashe is more valuable in teamfights, so Olaf should flank or ult through arrow to make her spend damage time running instead of free-hitting.

• •Do not start the all-in without landing Undertow first.
• •Ragnarok completely changes Enchanted Crystal Arrow from a stop button into wasted time.
• •Boots of Swiftness are unusually valuable if the fight is mostly Frost Shot kiting.
• •Cut off her retreat path with axes instead of throwing them max range every time.

Do not panic if Rocket Grab lands; Blitzcrank often pulls Olaf into the range he wants. Use Ragnarok after Power Fist or when Static Field plus knockup would stop your lifesteal window. Keep fighting through Mana Barrier with Reckless Swing, since the shield does not answer true damage pressure well enough.

Later Olaf wins the duel, but Blitzcrank's real value is catching someone else before the fight starts. In teamfights, Olaf should not chase Blitzcrank unless the backline is unreachable; ult through his disruption and punish the carries he is protecting.

• •Being grabbed is not automatically bad if your ultimate is ready.
• •Wait out Mana Barrier only if he is escaping; otherwise keep true-damaging through it.
• •Short axes stop Overdrive from turning into a clean disengage.
• •Static Field silence matters mostly before Ragnarok is active.

Avoid walking through Pillar of Flame just to land the first axe; make Brand spend Conflagration or Pillar before you commit. If Blaze is on you and Sear is available, either sidestep it or use Ragnarok as the engage begins. Once Sear misses or is ignored by Ragnarok, stay glued to him and end the fight before passive burn and Pyroclasm finish you.

Later Brand is far stronger in clustered teamfights than isolated duels, especially if Pyroclasm can bounce. Olaf should attack him from a flank, use Ragnarok for the stun window, and avoid taking a full combo before he has lifesteal uptime.

• •Do not duel Brand inside your own minion wave when Pyroclasm is ready.
• •Sear is only a stun if Blaze is already on you, so watch the setup spell.
• •Hexdrinker is strongest before Brand has enough damage to burn through the shield anyway.
• •Undertow after Pillar of Flame forces him to choose between dodging and finishing his combo.

Do not greed at low health just because Vicious Strikes is active; track whether Feast is available before extending. Bait Rupture with side movement, then use Ragnarok if Feral Scream or the knockup would stop your finishing sequence. Take short, repeated trades with Reckless Swing rather than letting Cho line up silence into Feast for the execute.

Later The side-lane duel stays close: Olaf has better sustained threat, Cho'Gath has a stronger execute and more health. In teamfights Cho brings area control, so Olaf should avoid spending Ragnarok on the tank unless killing him opens the fight immediately.

• •Feast punishes Olaf's normal low-health comfort zone.
• •Ragnarok does not stop Feast damage, so do not treat ult as an execute answer.
• •Sidestep Rupture before committing; getting popped up wastes your axe timing.
• •Reckless Swing is your best way to ignore his growing health pool.

Hold Undertow range and force Valkyrie before using Ragnarok for the real chase. Do not run through the full Valkyrie trail unless the kill is guaranteed; cut around it and keep axes landing behind his escape line. Commit when Gatling Gun is down or angled poorly, because armor shred makes his follow-up autos much more punishing.

Later Corki generally controls finished-build duels in open ground if he preserves Valkyrie, while Olaf wins only from fog, flank, or close starting distance. In teamfights Olaf should force Corki's escape early, then either continue with Ragnarok if axes connect or switch targets instead of being kited through missiles.

• •Valkyrie is the cooldown that matters; do not ult before it unless he is already trapped.
• •Step out of Gatling Gun's cone rather than trading into the armor shred.
• •Mixed damage makes single-resist stacking less reliable than health plus one key defense.
• •Axe pickup paths should avoid his fire trail whenever possible.

Do not commit your whole health bar into Mundo while Sadism is unused unless you have enough damage to finish through it. Dodge or sidestep Infected Cleaver before chasing, then use Undertow slows to keep him from simply walking out during his ultimate. If Sadism starts early, kite briefly with axes and re-engage as the regeneration window ends.

Later The side lane becomes a long stat check that depends heavily on anti-heal and whether Olaf can keep axes landing through cleavers. In teamfights Mundo is harder to remove, so Olaf usually gets more value diving past him unless Executioner's Calling is needed to keep him from overrunning the fight.

• •Executioner's Calling is the specific purchase that changes this duel.
• •Do not let repeated Infected Cleavers decide the fight before melee starts.
• •Reckless Swing helps against health stacking, but its self-damage makes Sadism timing dangerous.
• •If Mundo ults to disengage, keep the axe chain going rather than matching with Ragnarok immediately.

Keep enough health that her first Ravage combo cannot force you out before Vicious Strikes matters. When she appears, throw Undertow through her retreat path and use Ragnarok only if the slow would stop you from staying in range. If she fails to disengage after the first burst, Olaf wins the continued fight.

Later Olaf wins isolated duels, but Evelynn rarely has to take fair ones and is better at starting on carries. In teamfights Olaf should use axes and positioning to mark her exit path, then either peel her off allies or dive if she spends Agony's Embrace elsewhere.

• •Respect the first hit from camouflage; the duel is easiest after she has shown herself.
• •Throw Undertow behind Evelynn, not at where she appeared.
• •Ragnarok is for sticking through Agony's Embrace slow, not for panic after she has left range.
• •Magic resistance matters more than armor against her usual damage pattern.

Do not burn Ragnarok just to start the chase; first force Arcane Shift with Undertow pressure. Approach from fog or a side angle so his shift has fewer clean directions, then ult once he has used it or once an axe slow guarantees follow-up. If Essence Flux hits, wait a beat before fully committing because the attack-speed reduction cuts into your low-health DPS.

Later Ezreal is favored in open side-lane space when Arcane Shift is available, while Olaf wins from close starts or terrain traps. In teamfights Olaf should make Ezreal shift defensively, then decide quickly whether the chase is still realistic before Ragnarok expires.

• •Arcane Shift is the real escape; Mystic Shot poke is the tax you pay to reach it.
• •Avoid letting Essence Flux land right before your all-in.
• •Throw axes where Ezreal wants to shift, not only at his current position.
• •Banshee's Veil can block the first spell that would start his kite pattern.

Do not let Terrify force you to eat a full Drain before ulting; Ragnarok as you enter the decisive melee window. Save Reckless Swing and autos to punish Drain channeling rather than chasing randomly through Dark Wind silence. If Crowstorm starts from fog, walk out until the burst edge passes, then re-enter with axes if he has no fear control left.

Later Olaf wins the duel, but Fiddlesticks wins games through ambush ultimates and fear on priority targets. In teamfights Olaf should either interrupt his positioning before Crowstorm or ult through the fear and make Fiddlesticks spend the channel defensively.

• •Ragnarok turns Terrify from a duel-winner into a wasted cooldown.
• •Do not stand in Crowstorm longer than needed just to finish a low-value kill.
• •Drain is the spell to punish with immediate melee pressure.
• •Dark Wind silence only stops you before Ragnarok; plan the engage around that.
