A few months before the nunu rework I opened up a basic champion capsule that i had gotten from leveling up. I found two champion shards inside, nunu and gangplank. I immediately purchased both, nunu because I knew he was getting a rework, and gangplank because i had been eyeing him for a while. I have to say that was definitely a good decision on my part. I enjoy playing gangplank and the nunu rework is one of the best reworks to date. so i hope you all enjoy one-shoting people with this build

so i will start with the runes for laning.

predator is a must take on any offensive nunu build, it makes you extremely fast when you use it in tandem with your W

cheap shot is for the extra true damage that will be readily available due to nunu's abundant CC

nunu needs the extra AP more then the warding potential so eyeball collection is a must

relentless hunters bonus MS is a blessing for nunu

nunu relies on his abilities a lot so transcendence gives CDR and AP both of which aid nunu massively

as games begin to drag on Gathering storm will provide you with extra AP

next we will cover jungling runes

you will be using oracle lens to sweep for wards, so zombie ward will give you an extra bonus for doing this

ingenious hunter allows you to have your active items up more often

water walking will help you take scuttle fast and can aid you in charging up your snowball

since i started with laning for runes i will start with jungle for items

starting items are pretty basic, a jungle item and refillable potion
however the oracle lens is a big difference, well what you want to do is go through the enemy jungle with you oracle lens and knock out any wards you see, zombie ward will kick in and you will get free wards in the enemy jungle

hextech protobelt-01 has a lot of uses, it gives you AP,CDR, and health, all of which are useful to nunu. Also the dash can be used to amke sure that people get rooted by your E
runic echos gives you a mini ludens echo passive and some more AP and CDR so it is definitely useful

sorcerers shoes give you magic pen which is always welcome with the ammount of magic damage that nunu can put out. rod of ages gives you health, AP, which are always welcome, note that you should only get farsight alteration after you have bought the other two items as oracle lens is more useful until you get a sufficient amount of AP

for late game items i take spellbinder and rabadons deathcap
spellbinder is movement speed and AP both of which are invaluable to nunu
rabadons deathcap is how you get an enormous ammount of AP

Zhonya's hourglass can get you out of some really sticky situations
mejai's soulstealer can grant you a lot of AP early if you are getting a lot of kills

now on to the laning items

starting items are pretty basic, a dorans ring and some potions

instead of runic echos we get a void staff which gives us more magic pen and AP

instead of a RoA we get a ludens echo because we dont have the passive for runic echos
we also get a elixir of sorcery for the increased damage to champions and turrets

instead of a spellbinder we get a lich bane because you can take more advantage of its passive

Pros:
strong counter-jungling
high movement speed
EXTREMELY high damage
high zoning potential
good in teamfights
absurd healing
Cons:
needs to charge up his snowball to access most of his damage
E is escapable
venerable to being CC'd
ult requires a long channel time
squishy
ganks are predictable
mana hungry

make sure that you signal you allies before you come in to gank, it is easy to come into a lane and find yourself in a bad position

don't charge into a teamfight alone, you will go down very fast

you may be able to annihilate squishy's in the late game, but going after every squishy you see will cause you to be constantly sidetracked, allowing the enemy team to take objectives

your ult can make or break teamfights, a good ult can decimate enemy health bars, while a bad one turns you into an immobile sack of yeti fur for several seconds

For pathing i go
leash from bot to red buff
charge up W into raptors
go for enemy blue
enemy wolves
scuttle
Gank
your blue
your wolves
gank

nunu and willump are amazing junglers with a Q that acts as a second smite, a W that can obliterate enemies, hard CC in his E, and the same ult we know and love, he acts as an unstoppable avalanche of damage, crushing enemies under a hailstorm of snowballs and crowd control. i hope you all have a good time playing full AP nunu and willump
