Thank you for reading my guide! <3

Thank you very much, I'm glad that you liked it! ^^

The problem with her is that if your teammates are feeding or not playing well, you can't do anything to change that. You can save them in every possible way but they will still die.
In late game you should focus your skills on the ally that's fed the most., so if your ADC is not doing well, let him die. I think that polymorph > attack speed on an ally, so try to polymorph an enemy (assassin or bruiser most of the times) and let your team do the rest.
You can decide to ult at the beginning of the fight to follow your engager (like Malphite or stuff like that) or you can use it to save someone who's low HP, that's your choice and it changes on the moment, so I can't really help you with that.
Remember to stay behind your team and shield your frontline from enemies' poke.
I hope I helped you somehow, thank you for commenting my guide! ^^

I think that Zombie Wards can be useful because they last longer than Ghost Poros and can provide a better vision around the map, but I personally prefer Ghost Poro because they activate even if an enemy is invisible and the alert ping they do when an enemy spots it, tells you to run instantly. It happens too many times that even if we have a ward we don't see their jungler coming for a reason or another, it happens to me too, so I find Ghost Poro better for me than Zombie wards.
About Mikael's: I build it only if the enemies have 2 or more hard CCs (this includes Nasus' slow). It's a strong item, because its active heals an ally and with all the DoT of the 2 AP masks and Ignites you can save many lives, I admit that I should build it more often.
About Redemption: Yes, it is a strong item too and if you get focused you can still help your allies out, but I think that in this season there are too many strong items that kill you too easily, so if the enemies are fed, Redemption is gonna be quite useless.
Still, these are my thoughts and people can agree or disagree, I hope my answer has been clear and understandable.
Thank you for commenting my guide, I appreciated it. Have a nice day! ^^

Oh my God thank you so much, I'm really glad you liked it! ♥

Thank you!
I don't have many tips to counter her because there are only a few ways to do that. Build as much as Tenacity you can to make Polymorph last less time, focus her in teamfights if you can but i'ts risky because she can save herself in many ways. CCs on Lulu are probably the best thing, because if you CC her she can't do anything and you can kill her.
Never underestimate a Lulu because if you think you can kill her (maybe under tower) you are probably wrong.
In laning phase there are two ways to counter her:
- Try to trade as much as possible staying out from her range or just poke her to make her use her mana
- Play defensive and avoid the poke
If you're an engager support, focus her when engaging.

I think that this is all I can say about it, I hope I've been helpful!

Oh and I see the Summoner Spell chapter, I don't know why you don't, maybe try on another Browser.
Have a good day ^^

Well yes, Ardent Censer is great with ADCs that are based on auto attacks like Vayne, Jinx, Twitch, Kog'Maw and stuff. If you think you don't need the Mythic item as first item, you can build whatever you think will work best in that moment! ^^

Hi MrSoybean, I don't always build Moonstone, but most of the time I do and the reason is that my team often sucks and even with Mandate, they wouldn't even make it proc because they don't care/run away/don't even know what it is.
It really depends on the situation, but if I use Nami for example, I always build Mandate because she makes it proc using her E on an ally (if he attacks an enemy).
The Moonstone has been buffed lately though, I can heal more than 1500 dmg in a teamfight if it lasts some time! I don't really see its healing during the teamfights but I can see the recap if I go over the item on my inventory with the cursor.
Thank you for your comment, I appreciated it. ^^

Thank you very much, I'm glad it helps you. ^^

Haha thank you!

I'm sorry if you didn't like my guide or found it boring, but I didn't write it to be original. I just wanted it to be helpful for people who wants to know how to build Lulu or tips to play her. I'ts a simple guide, easy to read through (I think so at least) and as long as it helps people, I'm okay with that.
