IntroductionThis is my first guide and I'm not a pro just posting a guide for players to see how I play Nunu and do relatively well with him. Nunu is a really great Champion, I prefer to play him as a tanky Nuke because of his insane early game damage and still decent damage late game. I have played 13 ranked games with him and won 12 of them so far. I don't play ranked all that much but when I do I will play Nunu.
RunesThese are the Runes I run with Nunu. Magic penetration reds for early game damage until you can get some AP, your E hits pretty hard. Mana regen per level yellows so I don't have to worry about mana regen or mana items. Cooldown reduction Blues to get more E's off.
MasteriesYour standard 9/0/21 build not much else to say here.
I prefer Flash and ignite on Nunu. Nunu's W is a constant Ghost so no need for that and his E is a constant slow so Exhaust seems like a waste too.
Nunu can cast a spell for free after 7 attacks.
Pretty neat Passive can get more E's off for harass or more Q's for healing/last hitting.
Takes a bite out of target minion, dealing 500 / 600 / 700 / 800 / 900 damage and restoring 125 / 200 / 275 / 350 / 425 (+100% of ability power) health.
Cooldown 35 / 30 / 25 / 20 / 15seconds
A nice move to last hit with steal dragons/barons and heal with Max this spell out second.
W: Blood Boil
Increases an allied unit's attack speed by 25 / 35 / 45 / 55 / 65% and movement speed by 11 / 12.5 / 13 / 14.5 / 15% for 15 seconds. Nunu also gains the effects of Bloodboil if casted on an allied unit.
Max this spell out last just get one at level 3 for the speed boost. Apply this to Ranged carries or if none melee champions.
E: Ice Blast
Nunu throws a ball of ice at an enemy unit, dealing 85 / 130 / 175 / 225 / 275 (+100% of ability power) magic damage and slowing their movement speed by 40 / 45 / 50 / 55 / 60% and attack speed by 25% for 4 seconds.
Cost 75 / 85 / 95 / 105 / 115mana
Nunu's bread and butter this spell with the right amount of CD reduction can become a Perma slow. Max this skill out first.
R: Absolute Zero
While channeling for 3 seconds, slows nearby enemy units' attack speed and movement speed. After channeling, enemies caught in the area are dealt 625 / 875 / 1125 (+250% of ability power) magic damage.
Cooldown 150 / 120 / 90seconds
Nunu's Ulti, insane Ap ration and insane base damage trouble is getting this spell off. Banshees is really well of Nunu to help protect against some of the stuns that can cancel this Ult.
Item BuildsThis is the build I go with Nunu 90% of the time unless I'm really not dying to often I will go full AP maybe switch Thornmail for Abyssal Scepter, still keeping Banshees so my ulti isn't insta interrupted.
Early GameJust Farm, farm and farm until you have enough to grab a catalyst, once you do B and grab it and feel free to harass with E constantly If you take too much damage use Q to heal up.
Mid GameContinue farming when you can, Jungle a bit run around and gank enemies you see overextended.
Team FightsYour job in team fights is to press on enemy carries you are decently tanky at this point in the game so feel free to push the enemy carries out of the fight. After you see the enemies blow their big CC's ulti and do a ton of damage to their entire team.
Late GameStay with your team and wait for your tank to initiate remember you are NOT a tank just a tanky dps.
