I love going off-tank 1-ap support item builds. With the obvious Sightstone aside...
are pretty much my core items on her. Athene's work pretty well on Lulu since she pokes, shield is single target and that I spam it all the damn time, and that a kick of heals would help her anti-sustain by a lot. Or at least in my playstyle; it's pretty much a personal gift to Lulu from Riot.
if I need MR,
if I need armor. I don't like Randuin's because its active is pretty useless on a backline poky peeler like her, and that I like more mana + CDR over more HP.
if I still need more MR.
Used to run
for the MR path because of how stupidly cheap it was, then the mage rework highlighted the truth about its OPness.
Zhonya's is a waste of slot and money; its armor is too little for a offtank peeler like me and that its active would fuck up my peeling tactics. I am very horrid at using Mikael's so I never built that, Zeke's isn't that strong anymore ever since preseason where ADCs can get 80%+ crit quite easily, Censer is too situational of an item for me since IMO Athene's would benefit Lulu much more on lots of aspects, Morello's build path post-rework is strange on supports like me though if my team somehow still don't have GW I get that, and Righteous Glory... no, not when my team is full of usually chickens.
My builds in a nutshell.
