So this is my first build ever on Mobafire, so keep that in mind if you see a lot of noob things on this.
Nunu & Willump is by far one of the best, if not the best champ in the 450 IP range. He's a powerful jungler, but what I want to focus on is the lane-ing aspect of his game, so this is mainly for Twisted Treeline. I personally play and like 3v3s a lot more, mainly because it's less hectic, and a lot more fast-paced. Plus it's easier to get two friends and play with a full team than four friends for 5v5.
As a laner in Twisted Treeline, that doesn't mean Nunu never goes into the jungle, as he is very effective late game, contrary to 5v5 where he's near useless late game.
Nunu & Willump is an AP tank, so you would want to build MR, Armor, Mana, and AP so that you can take a lot of hits, harass hard with your Ice Blast and deal ridiculous amounts of damage with your Absolute Zero
LEHGO :D

Pros

Very tanky, can take a LOT of damage
Great harasser
Ridiculous AP-ratio with ult (2.5:1)
Decently fast without items
Very good chaser
Great ganker
Great at neutraling with

Consume

Cons

Loses effectiveness late game
Mana problems early game
Trouble clearing waves

And that's pretty much it!

Smite in my honest opinion is a MUST on Nunu. It gives him another quick minion-killing spell to couple with his Consume and is really helpful when taking dragon or red/green/black buff. Plus with the mastery that gives you 5 gold every time you use Smite, plus the reduced cooldown, it'll allow you to get more gold, and immediately wipe out two minions!

Flash I feel isn't necessary, but is the next best option to use. There's no real need for Ghost as your Blood Boil provides enough of a boost to get out of sticky situations, and Ice Blast is just as effective of Exhaust. Plus other teammates should have Exhaust, so not having it shouldn't be much of a problem. AND the masteries give you CDR, and who doesn't like CDR? :D

Other viable options:
Ignite works fine on Nunu as it adds on to his chasing capabilities.

Cleanse I find works pretty well with Nunu, as he'll be taking a lot, and I mean A LOT of nukes/stuns/whatever. So if ganked, just use Cleanse and Blood Boil yourself and GTFO

I chose to go a 9/0/21, because I feel that that best fits Nunu. As you can see, the Smite mastery gives you just a little more gold, which is always a plus. The magic penetration will help out your Ice Blast too!

For the Utility tree, everything helps. The Flash CDR, plus the additional CDR with Presence of the Master! Don't forget increased MP regen and max MP, along with the movement speed! The item's you'll get for Nunu will make him into tank anyways, so I don't see much of a point to put anything in the Defense tree.

This skill makes you into the good neutraler you are. Pretty much eliminates the need for health pots, or even needing to recall, for you can just use this once at max level, and it'll heal you up big time. You should use this whenever it's off cooldown, as it gives you easy gold. One level is enough really, and just max it out when you have nothing else to max out.


This ability is what makes you a great teammate. 65%/15% attack/movement speed bonus for 15 seconds at max level? That's ridiculous. This anytime you're with a teammate, Blood Boil him. When taking down towers, Blood Boil. When chasing, Blood Boil. Oh yeah, and when you give the buff to someone else, you too get the buff. It's great for running away and helping a teammate run away too.


Most commonly referred to as "snowball", this is your harassing spell. Once you get it at level 2, don't stop harassing the living daylights out of your opponents. It got nerfed a little, but a 4 second slow is nothing to sneeze at. If lane-ing against a squish opponent like Ashe, Veigar, or Annie, you can easily pick them off if they get careless. Snowball does a fair amount of damage early game, as it helps you catch up to your opponent when chasing them. You throw a snowball, then Blood Boil yourself to catch up and they're as dead as a doornail. Very useful for running away as well, as this ability has the potential to completely piss off the other team.


This ult is probably one of the most powerful ults in the game when it comes to pure damage. It has the max AP-ratio at 2.5:1, and in a team fight, you can easily score aces with this baby. The catch is that it's a channeling spell, so if you get stunned/silenced when charging, the spell will immediately stop. A must use in team fights, especially if your opponents are at half hp or less. The thing is, with this ult, your enemies can see the radius of it, so it can flash out of it.
*TIP* You can hide in brush and use your ult, then your enemies will get slowed within the radius but not see the circle! GENIUS!!!

-I always start off with a Sapphire Crystal as I find the extra mana really helps when I'm spamming Consume and throwing them snowballs at your lane-ing opponent. I opt for a health pot as well as a mana pot because of the relatively low starting mana and the fact that I'm Consuming and Ice Blasting right when it gets off cooldown.

Core Items:

Mercury's I feel is a must. Quick MR and Tenacity is perfect for Nunu. 'Nuff said.

Banshee's is also a must. If you don't get this, you're a complete goober. Seriously, the added HP, MP, and MR is such a boost. PLUS the passive is super helpful and will help you farm with much more confidence knowing that the opponent can't do **** to you.

I always get this with Nunu, and how can you not? You need to get this immediately after Banshee's, because of its passive, the increasing stats as time goes on. You can actually afford to get this before Banshee's if the other team isn't pressuring you too badly, and you farmed enough. The HP/MP boost is always welcome, plus it's your first considerable AP increase, which will definitely help with your E ability, Ice Blast.

Situational:
Now here is where you can be creative, for a lot of items work well with Nunu.

I usually take this next. It gives a good amount of AP, and a lot of HP. Plus the added slow always helps.

I take this last, or sometimes right after RoA if I need that armor. Big armor/MP boost, and CDR. Great! Makes you even more tanky, and allows you to spam that Blood Boil and powerful ult Abo****e Zero more!

The rest is really personal preference. Lich Bane can work really well, as the AP, MP, MR, and MS will all help Nunu. If you need to go pure tank, take a Warmog's Armor or a Sunfire Aegis (Sunfire if you want to be a **** hahaha). I would even go as far to say to get a Rabadon's Deathcap if your team is winning and you want that insane AP boost to make your ult to massive work.

Not really big on the runes, but if you see, I focused on the following things:

Magic penetration
AP

I don't really dig deep into runes, I just get whatever helps Nunu. You can't go wrong with any armor/HP/MP/CDR runes, as they all help Nunu do his job.

So that's it! I really hope I did okay and I can help people out on who I think is one of the best champs in the game. Just remember the following things when going Nunu:

Never stop being as gay as you can. (Gay as in annoying/frustrating). Your best asset as a laner is your 4 second slow in

Ice Blast. If you use this enough, you can gain a heavy leveling advantage because your opponents will try to avoid your snowball of death.
HELP YOUR TEAMMATES. Use Blood Boil to get them out of sticky situations, or to push for that tower a little quicker.


Enjoy, future Yeti riders! :D
