INNATE: Nunu's and Willump's next instance of damage dealt to an enemy champion, large monster or structure grants both Willump and the nearest allied champion within range Call of the Freljord for 4 seconds, prioritizing the ally with highest attack speed.

CALL OF THE FRELJORD: Gain 20% bonus attack speed and 10% bonus movement speed. If Willump is affected by the buff, his basic attacks additionally splash 30% AD physical damage to secondary targets in a cone in front of him.

Nunu and Willump cannot trigger Call of the Freljord from the same enemy again for a time. Successive triggers of Call of the Freljord will stack the duration.

This passive is not the most useful. The main usage of this passive will be to clear camps or minions faster before players come to contest it.


Active: Nunu commands Willump to take a bite out of the target enemy minion or monster, dealing true damage after a 0.4 second delay and healing himself.
Well Fed: Nunu gains 2% maximum health, bonus magic damage on his basic attacks, and increased size, as well as 10 bonus movement speed while out-of-combat, stacking up to 「 5 times 」. Stacks fall off one at a time every 55 - 140 (based on level) seconds.

The bread and butter that activates this entire strategy and defines Nunu as the hypercarry he is. Timing the Q is everything, as your Q damage will always outscale junglers' smite damages. Max this first to make securing camps much easier.
When smiting and Consuming at the same time, be sure to Consume first, as there is a bit of a cast time so it gives aware junglers a window to outsmite you. Avoid this by smiting 0.4 seconds after you cast the q to remove this window.


Active: Willump cleanses himself from all slows and channels for up to 10 seconds, becoming ghosted and conjuring a snowball snowball that he begins rolling in the direction of the cursor while automatically navigating his movement. The snowball increases in power over 5 seconds and expands in size over the duration. Willump can also steer the snowball with a slow turn rate that increases over time; changing direction resets the turn rate. Biggest Snowball Ever! can be recast after 0.5 seconds.

Very useful ability. Gives mobility and solid waveclear. If you full channel the snowball and explode it on the back line casters they will all die. Utilize this ability if one of the lanes is getting too ahead. You can use it to gank them.


ACTIVE: Nunu swiftly throws a volley of 3 snowballs in the target direction over 0.4 seconds, each snowball shattering upon hitting an enemy, dealing magic damage to enemies in a cone.

DAMAGE PER SNOWBALL:»
16 / 24 / 32 / 40 / 48 (+ 6% AP)
Enemies hit 3 times are slowed for 1 second. Champions and large monsters hit once are also Snowbound for 4 seconds, refreshing on each hit. Snowball Barrage can be recast twice within 3 seconds at no additional cost.

SLOW:
30 / 35 / 40 / 45 / 50%
RECAST: Nunu hurls another volley of snowballs, mimicking the first cast's effects. An enemy may only be slowed once for being hit by 3 snowballs.

After 3 seconds of the first cast, Snowbound enemies around Willump take magic damage and are rooted for 0.5 − 1.5 (based on level) seconds.

This ability is useful for securing small minions that you don't want to use q for. It does a small amount of damage so it is hard to use to secure kills. You don't want to root people too much with this ability because then your team might secure the kills. This is the crux of your carry strategy. By appropriating all the gold and resources on your team, you can carry your bad teammates and rise to gold.


ACTIVE: Nunu and Willump channel for up to 3 seconds, sapping heat from the surrounding area, slowing enemies within by 0% − 95% (based on channel time), as well as gaining a shield. Absolute Zero can be recast after 0.5 seconds.

SHIELD:
65 / 75 / 85 (+ 150% AP) (+ 30 / 40 / 50% bonus health)

When Absolute Zero ends or is interrupted by any means, the area explodes, dealing magic damage to nearby enemies, modified to 0% − 100% (based on channel time). Affected enemies will remain slowed for 0 − 3 (based on channel time) seconds and any of the duo's remaining shield will decay over 3 seconds.

MAGIC DAMAGE:
625 / 950 / 1275 (+ 250% AP)
RECAST: Nunu and Willump end Absolute Zero early.

The classic pentakill ability. You have probably seen clips of Nunu players channeling this ablility in bushes and getting pentakills. However, this is extremely unreliable, as there are many champions with CC abilities that can easily interrupt this ability. Because you are unable to move while channeling, you are an extremely easy target to lock down. Also, there is a chance that the bush you are ulting in is warded, and you will just die and look stupid for wasting ult.
That being said, the key to being successful is managing controlled variables. Enemy champions and friendly champions are all uncontrollable variables. Therefore, it is best to use this away from any champion.
For example, when you see a wave crashing in top or bot, you intercept it between inner and outer towers and use your ult to clear it. This is an easy way to get almost a kill worth of gold extremely quickly without wasting much time. As long as you are sure no champions are nearby, consider your ult just a standard gold generation.

So, the obvious question, why smite? The answer to that is that you need to maximize your gold income so that you can carry your teammates effectively. This may involve some negative feelings towards you on behalf of your teammates. Do not be discouraged, as they are probably hardstuck and you will be gold soon. Make sure your team knows that you are utilizing this guide so that they don't think you are just a troll. If you are experiencing many dodges, just switch to smite at the last second. This summoner spell is irreplaceable and you must take this in all cases.
