Hello and Welcome

This is my first guide so please enjoy and tell me how I did :)!

Pros

*Fun to Play
*Self Heals
*Strong Defenses

Cons

*Slow Movement
*Low Attack Power
*No Constint Aoe

Visionary:Passive

- After 7 autoattacks, Nunu's next spell will have no cost.

This ability will allow Nunu to be able to use his abilities without mana at times so you don't have to keep going back for mana as much.

Consume:Active

-Nunu's Yeti takes a bite out of target enemy minion or neutral monster, dealing true damage to it and restoring Nunu's health.

Cooldown: 18 / 16 / 14 / 12 / 10 seconds
True Damage: 400 / 525 / 650 / 775 / 900
Health Restored: 125 / 180 / 235 / 290 / 345 (+1.0 per ability power)
Cost: 60 mana
Range: 125

With consume this allows Nunu to be a good Jungler but I personally prefer to lane Nunu because of ganking takes care of all the gold issues.

Blood Boil

- Invigorates an allied unit by heating their blood, increasing their attack speed and movement speed for 15 seconds. If cast on an ally, Nunu also gains the effect of Blood Boil.

Attack Speed: 25 / 35 / 45 / 55 / 65 %
Movement Speed: 11 / 12 / 13 / 14 / 15 %
Cost: 50 mana
Cooldown: 15 seconds
Range: 700

With this move its always the best to target another player in your lane if there is one if your not soloing if you are soloing just do Alt-W to so you don't have to target yourself to save time.

Ice Blast

-Nunu throws a ball of ice at an enemy unit, dealing magic damage and slowing their movement speed by a percentage and attack speed by 25% for 4 seconds.

Cost: 75 / 85 / 95 / 105 / 115 mana
Magic Damage: 85 / 130 / 175 / 225 / 275 (+1.0 per ability power)
Slow: 20 / 30 / 40 / 50 / 60 %
Cooldown: 6 seconds
Range: 550

With Ice Blast, because of all the ability power that I said was a good idea to get well this is one of the reasons since the more ability power you have the better this spell will do and thats a great burning gank spell right here with the slow added too it.

Absolute Zero

-Nunu starts channeling and begins to sap a large area around him of heat, slowing all nearby enemies movement speed by 50% and attack speed by 25%. After channeling for 3 seconds, he deals massive damage to all enemies caught in the area. It can be canceled early for less damage.

Cooldown: 150 / 120 / 90 seconds
Magic Damage: 625 / 875 / 1125 (+2.5 per ability power)
Cost: 150 mana
Radius of AoE: 575

With your Ultimate in your hands is your greatest spell for killing your enemy so you have to make sure you time it just right so you can cause the most damage with it possible

Greater Mark of Insight x9

-With this rune will help with your abilities deal more damage during the game and this rune is more effective to use than Greater Mark of Potency since this will cause more damage because of the greater Magic Penetration.

Greater Seal of Replenishment x9

-With this rune will allow you to regen more mana if your having problems with mana regen, if you are not you can use Greater Seal of Potency instead.

Greater Glyph of Potency x9

-With more ability power from this rune will allow you to be a greater effect during the early game and be able to defeat your enemies more easily and get the upper hand early game.

Greater Quintessence of Force x3

-With more ability power late game can also help that is why my quintessences are taking care of late game while my potency takes care of early game.

With my Defensive build style I can survive easily while have my maximum amount of ability power I can gain out of my masteries with a 9/21/0 materies set up.

Beginning Items

-This is how I normally start out because once you obatain 2 Doran's Rings this becomes alot easier.

Early Game (boots)

-With these boots its reduced CD can help you with dealing more damage.

-These are the boots are normally get and I find them very effective

Early Game

-This is the only way I normally start out and it works very effectively withe bonus health and mana I can get on levels and bonus ability power.

Mid Game

-I use these so I am able to gain as much ability power as possible while also getting bonus slows on my opponents with the scepter

- I only start off this way if I'm with another person in my lane that can stun the enemy that I'm ganking.

-I only use this set when I am able to have a teammate stun so you can get the kill easily.

End Game

-This is the best set that I figured out since it will deal the most damage and you can defend yourself with the hourglass.

-I personally don't like using this but it can work but I just find other spells better.

-With this spell is ok but I would prefer using flash since it can be used more effectively.

-With this spell is not worth it because your consume takes care of the job.

-With this spell its not good enough at all for nunu because the only way its really worth anything is for a tank and thats still a maybe.

-Its fine since Nunu is able to jungle I'm just not focusing on that side of Nunu.

-With this spell is useful you can use if you think you have the ability to get out of combat with having to use flash but for beginners I would recommend flash instead to help get out of combat.

- With this spell is ok but there are others that can be used much better since if your having the Mercury's Treads these aren't going to be very effective.

- With this spell is more of a tank style spell its fine to use but I wouldn't recommend it since it ruined my damage when I used it.

- you can use Clarity if you have major mana problems in place for ignite or exhaust which ever you prefer

- With this spell is effective when you need to finish off your opponent when that have little to no health left.

- I would not use rally at all since you would need a offensive mastery set up to get any ability power out of it and with that its close to useless for Nunu since he needs as much ability power as possible.

- This is an ok idea to allow you to see part of the map for 6 seconds but you can have better options too allow you to have better control over the battle field.

- With Flash I recommend this spell for beginners since you can get out of battles faster and also you can just use Ghost until you learn flash.

If some how you were stuck with Soloing top with Nunu you can simply play in a defensive manner, make sure you always have Ice Blast up so you can hit any enemy champions to taunt them back.

If you for some reason solo top while both teams have a jungler in place make sure you try to play as offensively as possible if your going against another melee, if your going against a range try acting like your going to kill them as a taunt to allow you the upper hand in any battle.

Nunu can work well as Mid its just trying to find a balance between blood boil and Ice Blast on the enemy champion so you will be able to get the advantage, to be able to gank the enemy from any angle.

When your in a situation of a 2v2 make sure you always target your Blood Boil on the other teammate champion in the lane so you both get the bonuses from the effect and make it easier to taunt and push the enemy team back.

I wish to thank you for reading my guide and wish you good luck as lane Nunu where ever you might be placed.
