Olaf

Olaf is a melee fighter who asks one question: can you actually hold him? Ragnarok makes him immune to crowd control, so for its whole duration the answer is no. While he's running he picks Undertow back up to throw it again almost immediately, keeps his target slowed, and hits with a Reckless Swing that armor doesn't reduce.

Berserker Rage inverts the usual logic of a wounded champion: the lower his health bar, the faster he swings. Stack that on Vicious Strikes, which converts his health into attack damage and returns life on every hit, and you get a champion who becomes dangerous at the exact moment he looks dead. The price is a total lack of escape: commit badly and he simply dies.

Reckless Swing deals raw damage, which makes him one of the few champions on this roster who doesn't care about enemy Thornmail or Frozen Heart. Ragnarok deletes the entire game plan of most supports and control mages: roots, stuns and slows become wasted buttons. And Undertow, retrieved on the way in, gives him steady lane pressure without draining his mana.

Against that, he's readable. No dash, no leap, no shield. Reckless Swing costs him his own health, so he can genuinely kill himself trying to close a kill. Any composition that keeps him at range and refuses the melee exchange makes him irrelevant, and a well timed blind removes his whole point, since his sustain runs entirely through basic attacks.

Top lane, your early harass is the axe thrown at the edge of your range and then picked up as you step forward: you refund the cooldown and slow your opponent on the way. That cycle wins the lane, not auto attack trades. Never throw Undertow without a plan for retrieving it, or you wait an eternity for nothing.

Vicious Strikes goes on after the trade starts, not before: its lifesteal is what wins a fight you opened from behind. Save Reckless Swing to finish, because you pay for it in health and your health bar is your real resource. Against a ranged opponent, accept farming under tower until your ultimate, you own nothing that closes the gap before it.

Level six changes what the champion is. Ragnarok doesn't add damage, it removes obstacles: from there, an opponent who was relying on a slow to survive has no plan left. Always press it after the first piece of enemy crowd control, never before, or you spend an ultimate for nothing.

The second spike is your first health item. Vicious Strikes turns that health into attack damage, which makes defensive stats offensive on him: Frozen Mallet buys survivability, a permanent slow and damage in one purchase. After that, every item that shreds enemy armor pays double, because basic attacks are the bulk of your output.

Don't engage first out of habit, arrive second on the target that matters. Your value isn't soaking spells, it's reaching the back of the enemy formation and staying glued to the carry until he falls. Ragnarok exists for precisely that: walking through the wall of crowd control they built and arriving where nobody wants you.

Hold Undertow to catch the target peeling away, not to open. A missed throw on the engage leaves you with no slow at the moment you need it most. And remember Reckless Swing bills you: if you're already low, the basic attack that heals you is worth more than the raw hit that kills you at the same time as your target.
