Hi All
Here's another Nunu & Willump support guide for you. I have been playing Nunu for quite some time, but began life out in the jungle. It's useful for you to know that I'm not a pro player, I'm simply 1200 elo in soloque. I wouldn't normally take the time to write a guide, but I found every other to be different to mine, yet I've had some success - so here's what works for me!
Please vote and leave constructive feedback if you don't like it!

I will return to add a section on the abilities and update as I feel its needed.

That's it!

It's crucial you understand that the very early skilling order is flexible. Less so once you hit level 5!
So, level 1:
If you invade, take snowball
If you take duo golems with your AD, consider consume. But be aware it will make you less useful up to level 3.
Take W if you end up stood in lane with your buddy
Level 2:
Take W or E if you didn't at level 1.
Level 3:
If you took consume early, you now want to have all 3 spells available. If you did not, do you need consume now? how is your hp!? You shouldn't need to if you use the pots wisely, but if you do, there's no harm in taking consume now.
Level 4 and 5:
Make sure by level 5 you do have consume and snowball. You are now in the process of maxing W.

Note: Iceblast slows your opponents movement and attack speed. When you add a 2nd point into iceblast though, the attack speed reduction does not change. With bloodboil, your targets (and your own) attack speed will improve each time it levels up. Therefore, I max bloodboil before iceblast. Once you hit level 6+, the damage from iceblast is not worth worrying about.

These are my preference, and why:

- 1 extra pot isn't really worthwhile!
- I personally enjoy a mobile character, and with the oracles you will buy in the mid game, it really helps you make the most of it
- I actually quite like this, though it's not everyone's preference.
- the only buff you'll ever get is Nashor, and although useful to have it for longer, you are not the 1 who is going to carry your team when you do get it. So, just hurry your team along when the buff turns up! I do consider this surplus to requirements.
- I had a spare point and don't see it going elsewhere. The masteries are much more important early game, and this does help you stay in lane whilst you need to.
- your ulti has a horrid cooldown, as does your consume. Consume helps you in lane, and i dont need to talk about the ulti!

Ok so we want to be running around with the elixir as much as possible.

Not long on here people!
is a must, best escape spell in the game, and Nunu is no exception.

Viable Choices

In premade games, I'd recommend Clairvoyance as you should have the communication in your team to be able to gain some good map control. It's much harder when you are typing "please use CV here"!
Heal can be taken if your AD wants to take ignite or exhaust. If they take heal, you take exhaust. Simplesssss

I would not consider any other summoner spells

As you should know, when you ultimate there is a ring around you - that ring is visable by the opposition but only if they can see you - so, get in the brush and hope they walk into it! In bottom lane, i've set up some really easy double kills for the AD using this tactic. It then forces them to buy extra wards for the brushes at the bottom.
Team setups that favour Nunu & Willump require AoE damage. Amumu and Galio have a nice stun that allow you to use your ultimate without it getting interrupted.
Remember, in team fights you want to Iceblast their main AD threat. It reduces their damage significantly. It is just as important to do this as it is to pull of an ultimate.

Rather than re-writing what someone has already done, please see the guide below for more information:
Warding
Many people will place wards in a similar place to this - if you are using an oracle or vision wards, go check these places to be able to destroy enemy wards!

Thanks for reading this far. I will continue to make improvements, and feel free to comment. Key for any support is to ward the map effectively, and stop the enemy from warding at the same time - anyone can cast the spells in a specific order, or buy items that some guide tells them is right, but supporting your team in the best way takes practice. You need to understand who to aid most in your team, and who to shut down in theirs.

Happy gaming
