Thing is, i think she should be build like AS/on-hit carry.
Try building these items : Wit's End, Madred's Bloodrazor, Malady and Nashor's Tooth. They'll give you nice on hit effects, stacking with your passive that deals about 100 mage dmg at level 18, and giove you about 2.1 AS, meaning you hit extremley fast, and dealing dmg as fast.
So because u need some survivability, you may buy stuff like Rayali's Crysta Scepter, btu seriously, try her as AS/on hit carry.
You give her 2 hp/ap items, 1 hybrid item, atma's and trinity. That is a very wierd setup, because shes not really benefiting so good from AD, needs way more as, trinity is useless, you cant spamm your abilities.

And please, improve your coding, dont let walls of tet in there, and make guide a bit longer.

You make the usual 6 chaopters, bt you got no laning, gameplay, farming, teamfighting, etc etc sections.

And ADD ITEMS SECTION. ITS THE MOST IMPORTANT ONE OF THE GUIDE!

So yeah, you have alot of work to do :)

kk, thanks guys ill give some of your sugestions a try all the spelling is fine but i looked over it again a few gram errors will put them straigt. Obv she is a new champion and getting her to full build in a game is hard (not playing v bots doesent give a good guide to potential) so only been able to build trin force once ... was maby thinking about switching for hextech or even rageblade will play some more games and update ttyl

Your build is decent, but i prefer going with a 22/8 mastery with ap/lvl and magic pen runes to support that damage that lulu puts out in team fights. somewhat ok guide.

Maybe you should check your spelling before commenting others...

1st check the spelling\grammar
2nd i dont think trinity suits her. If you look at her cds youll notice you dont often get the sheenproc, plus you want to stick to targets, so frozen mallet would be a better choice i guess

Edit:writing on the phone is meh.
