My name is Nyftt, getting back into the game as of recent, in S9 I held 5 diamond accounts and peaked at Diamond 1. I am a jungle player that plays Nunu & Willump, Evelynn and Kha'Zix mainly although I also play Olaf and many other junglers.

I've taking a break from streaming but will start again when I'm a bit less busy with university. Here's my twitch link if interested https://www.twitch.tv/nyftt_lol. Did coaching and generally enjoy helping people out so feel free to message if you see me online.

Although this is the same for every other jungler, I'd say that Nunu's gank potential and abuse of Flash cooldown is even greater than most champions. Therefore you should try to pick a lane (or two) and make their life hell.

"Well which lane(s) should this be?"

Before the game even starts (champion select or even loading screen) you should think of which lanes are your win conditions. For example let us say your toplaner is a Maokai vs Trundle, Midlane is Malzahar vs Veigar and Botlane is Draven & Nautilus vs Kog'Maw & Lulu.

In this example Maokai will be useful no matter what as he will bring CC to the table and will have some tankiness even if he is behind (although less of course the more gold he is short of). This now tells us that Toplane is not our win condition.

But who is?

Well Botlane and Midlane are both nice ganks but we must factor in that Veigar's Event Horizon makes the gank basically impossible unless it is on cooldown and therefore we will try to camp bot and gank mid whenever we are near and we know his Event Horizonis on cooldown (BY LOOKING AT THE MAP AND ASKING MALZ NICELY :P) and when Malzahar has his Nether Grasp. Therefore the game plan this game would be to camp

Botlane

straight into hell and come mid when our previously spoken of condition is met. As well as this Draven is very snowbally (hehe) with a clear advantage over Kog'Maw in the lane and scales less well so you really want to abuse this phase of the game and make Kog'Maw unable to scale into the late game. With Nautilus's setup and the lack of mobility from Kog'Maw and Lulu you basically know that without Flash they are dead men. Therefore this game you want to hover around bot side, get deep vision, contest early drakes with this natural bot lane priority which is simply put "their ability to make more plays and rotation due to the great early strength of this lane."

Against Kog'Maw and Lulu you can easily just Biggest Snowball Ever! into their lane and massacre them over and over again. You should make sure to know when their Flash is down as this will be free and if it is up you can gank anyways to force them to use them so that your future ganks are guaranteed.

Nunu & Willump has some of the best objective control in the game.

Dragon and Rift Herald control

His Consume enables him to both take early Dragons on his own due to it's sustain and damage

Baron Nashor control

Smiteing is sometimes coin flip if you are either trying to Flash in and steal are Baron Nashor and worried about the enemy Jungler coming to steal it. With Nunu & Willump, this fear is gone. Due the combination of Consume and Smite you are able to secure the Baron Nashor at a threshold of hp incontestable by the enemy jungle and therefore it makes the securing of [Baron Nashor]]s extremely easy.

"You said a list of items are good but wtf do I build in my game stupid guide maker?"

Which boots do I go?

Vs. a team comp with a lot of CC go Mercury's Treads.

Vs. a team comp with a lot of auto attack damage go Ninja Tabi

When behind or needing to match the enemy Jungler's aggression go Mobility Boots and late game change them for either of the two above.

Other items + item tips:

Knight's Vow: Go this when you have a person who is hard carrying and you want to ensure their survivability (and your own as the more damage they do the more you will heal for)

Gargoyle Stoneplate: This is probably my favourite item in the game because it gives both MR and Armour and the active is very gold efficient, when behind and in dire need to win a fight I sometimes rush this item. I end up building it 3rd or 4th item most games.

Spirit Visage: I just wanted to mention that due to the healing increase propety of this item it has insane synergy with Nunu & Willump, when the enemy has even a moderate AP threat the survivability that this item provides should always be at least considered.
