I like the way you think, usually i play nunu support almost exactly this way and roflstomp all the time. Really REALLY smashes lanes that have no form of sustain. Keeps you dealing damage all game. Its a good guide, but i would think about expanding a little more and putting in some more tips and tricks, maybe bling it out more, and yes put it through the grammar hammer, and it will be an amazing guide XD Maybe throw in getting an early kage's lucky pick to assuage those people that say all supports MUST have gp10 items. Cause ya know. Doing a 1k damage ulti at lvl 6 after using a 300 damage slow nuke wont get you kills or assists or anything...

edit: Gave it a bump cause i know you will work on it and make it baws XD

:)
i was too tired to check for mistakes,i made a small guide compared to the others,but damn...it was so exhausting

Put this through a grammar hammer and it'll look over 9000 times better.

+1 for effort

i know,it's a problem in the begining,but i've tried this on ranked,and i feel that i've helped my team more compared with the other times that i had support items

yeah i build ap,but im also helping my ad to farm by suppporting him
i just made this guide because i believe that nunu helps more on bot lane like this
if he buys support items,with support runes,his E+ulti deal no damage at all,but with my build,1 hit on the enemy ad is so much dmg which means that will be afraid to farm,recall or even die

u have no gold gain, u cant get farm cause ad carry needs all of it

u have no gold gain, u cant get farm cause ad carry needs all of it

I won't downvote because this is a good item build for nunu, however your title is a misnomer. This is a nunu tanky-ap build--not a support build (besides the clairvoyance). Especially in ranked, not getting a ward until around your third time back (which seems like what your build is), is not a good thing as a support. Rename your guide or switch around your build. (Remember, there is an option to add more builds to your guide.) PM me back after you make some changes and I'll give you an upvote :)
