Hi! I am a main jungle from LAS, so you can probably deduce that english aint my first language so be warned, there is going to be more than one grammatical mistake. I started playing back in season 4 but I stopped playing after Season 6 started and recently started playing agaain at the begging of season 9. I ve reached Platinum 3 so far, with 70% win rate on nunu, but I have faith on my skills, maybe I can reach Diamond (wish me luck). Anyway, Nunu (high tier) has been my jungle main along with Zac (low tier), I decided on making my first guide on nunu as it is a much popular champ, although I will probably make one for Zac but that one is going to take a whole lotta time (Led Zeppelin reference)

You better take Flash and Smite if not you are low key kinda trolling, I guess there are other summs that maybe can be kinda useful, but flash is overpowered to the point that only a handful of champs don´t use it, so dont me dumb.
If some day you are bored you can take tp and go for some strange ganks but that is about it.

Please stop following the item paths you see on mobafire, try and use your imagination, countless times I have people building against full ad teams just because they were following the build they saw here. Small mistakes have large consequences, this one is quite easy to avoid.

This is likely to be the largest chapter but idk.
Nunu has one of the best clear times in the game and can perform full clears without flinching.
The new Scuttle Crab changes actually hurt Nunu usually you cleared one side, fight scuttle (if you started red side, you were level 3 and won every 1v1 with the ease) and either go for a gank using snowball + speed buff or go for vertical jungling. the scuttle crab change now allow you to make a full clear and go for the crab with level 4 which gives you less early pressure but it could be worse.
It is of much importance to have scuttle crab, the speed buff + vission controll gives you the opportunity to gank several times the two lanes you have closer to you. As you have such a fast clear you won´t fall down in exp by ganking so many times. If there are no ganks available you may go for deep wards, counterganking or just back and buy the "Casual Back".
Ideally you can gank, one succesful gank will likely grant you the "Juicy Back" and two succesful ganks will give you the "Super Juicy Back"

You can harshly kill dragon at level 5 using the two potions and maybe an early smite depending on the drag so be careful but from there on you can solo them quite effieciently. The rift herald is the same, always have a pink on your inventory and try to keep track the other jungler when doing any of them.
Also you cant lose any 50 50 smite as your Q deals 980 true damage, around level 7 your Q even out smites smite, so you better not grief.

1v1 pre 6 you have a decent burst when you combine your w q e + passive aa, but you quickly decay, so if you arent sure your enemy is within that damage threshold better not risk it, specially considering the high cooldowns. After 6 your 1v1 is better, the ultimate gives a decent shield that often catches enemies off guard in a 1v1, also useful when cheesing, though as you will often build it as a tank, that strategy aint that reliable.
In a Teamfight you lack the damage to kill carries so you have to play alongside your damage makers, so you mainly peel and support with the needed cc to kill tanks or any enemy that isn´t well positioned. Your Ultimate is very useful in teamfights it is an incredibly strong peel ability

Nunu´s snowball has a hitbox that can be heavily abused, when ganking aim to the space between the champ and where he would flash, if he sidesteps to the side contrary to the flash and dodges your snowball his basically dead as you just drop the snowball and use your.
It is essential you hit the enemy with the e just after you hit your snowball, with just one hit you can already root them, so even if he flashes you can chase a bit and cc them down. Nunu is increidibly strong because having flash is no security, if you add up your ult to this, the slow + damage makes every gank with your ult a kill secured.
You don´t really rely on killing to be strong you will just get more tanky, you should always try to give the kill to your laner.
ALWAYS e before you ult, they get rooted even if you are ulting
I think there are practically no curves you cannot do with your snowball, though many require perfect maneuvering.
You have a decently good initiation if you use your snowball from base with the after 20 minutes speed buff. you can reach the center of the map in a matter of seconds.
You don´t really need to get leashed, but it gives you a better overall clear time.
Try to play around the top side, the lane is wider and gives you better angles to enter with the snowball, in addition supports tend to have the neccesary cc to interrumpt your snowballing.
Always have vision control over pixel bushes, if the enemy wards on the nearby bushes to their lanes, these will not be effective against nunu (another reason why he is so strong at ganking), if they spot you when you create your snowball (around the pixel bush or the crab speed buff, they can react)
The healing from your Q when you are below 50% health in addition to the shield provided by your Ult can be an extremely good bait. Also two abilities very good at diving.
Play around your carries, always, you are not a lone wolf you are just a child with a yeti

I´ll probably keep adding tips, I gotta go to sleep, feel free to comment offensive and toxic things ;D, nunu is positivity
