Threats to Olaf with this build

Show all
Threat Champion Notes
Irelia You directly counter Irelia in this lane. Poke her with Undertow until she has to leaves lane. If she doesn't, kill her.
Nasus Nasus has a very weak early game and Olaf is one of the best champions in denying farm. You should be fighting him constantly early game when he is weakiest. Make sure when you fight him there is no way he can fight you back without dying, you don't want to give him free kills so he can get back into the game. Also you should keep on eye on him lane, do your best to not let him farm by himself.

Pros / Cons


Falls off late game
Reckless Swing can easily kill you while getting bursted early game
Has a ton of mana issues early game

One of the best DPS off-tanks in the game
Has high amount of burst to use on ADC's and AP mids
Ragnarok is a very good ultimate for a tanky champion
Olaf's Undertow is basically a perma-slow if used correctly

E max isn't as good as it once was, they nerfed E so its better to max Q for the burst damage and the perma slow if you can land it constantly. With the Q max you can on the ADC forever until there dead. Its basically a watered down version of Hecarim , except no CC can effect him, true damage, and a perma-slow.

E is still good as ever early game but again Undertow is just better as of right now.

Greater Mark of Attack Damage

Greater Seal of Armor

Greater Glyph of Magic Resist

Greater Quintessence of Attack Damage

This runes are flat AD,flat ARMOR,and flat MR reds,yellows,and blues. These function great for Olaf as he is DPS off-tank that scales AD. But since he's a tank he needs to be able to take damage for the rest of his team. But also if hes team is lacking in damage Olaf can come in and save the day with a couple of Reckless Swings and a number of will thrown Undertows. Also you don't have too follow my path and play Olaf with this runes (even though I highly recommend it) you have a choice to use the runes you have set up for yourself. Just wanted to let you know that.

Olaf is a DPS off-tank as I previously mentioned. But now where are going to talk about how Olaf can be useful in a teamfight. Now lets get started

Useful Olaf

As Olaf your one of the many champions that can get easy access on the backline, What your job is to do is pop Ragnarok and go straight for the ADC or the mid laner (whoever is more of a priority). Don't bother to go on tanks till the enemy ADC is dead or you need to peel for your ADC. As Olaf You should be the one engaging because of your ultimate or you can TP flank instead if your team has better engager then you like a Warwick or a Thresh . What you shouldn't be doing in teamfights is fighting the support or fighting the tank. You should be on the ADC or the most fed player on there team that poses a threat to yours NO MATTER WHAT. Also you need to know when to teamfight. You can't just charge in waving your axes like an idiot when your team is behind. Look for picks. Look for objectives. Coordinating with your team when your behind is the most important thing to do if you want too get back in the game. Wasting time calling people ******s and telling them to kill themselves will never you win a game. Ever (unless the other team throws hard)

Last hitting in this game is core and will result to you being ahead of your laning opponent and giving your team the advantage. If you don't know how too last hit then go in bots and practice to last hit without runes or masteries with any champion. Do this before you start to play every single day. This will improve your last hitting more overtime.

Backdooring doesn't as you might think, sure what Xpeke looks easy but it takes an immense amount skill to do it like that. You need to make sure you weren't spotted by a ward, need to make sure the other team is not in the base when you attempt to backdoor. With Olaf it gets easier to back door because of his ult and and because he is AD. Make sure you see all FIVE players of the enemy team or know where they are at before you attempt to backdoor. Since you should have Teleport this will make it way easier then without teleport because of wards etc.

Game play

If you need some help understand how Olaf is played you should watch some gameplay.

Here are some videos and video guides that explain what an Olaf should do that I recommend you watch.
