I mean sorry, which I think you should add. It's attack speed is fantastic for the extra procs for passive + it's passive will make you deal 120% total ap every 3 auto attacks.

Be sure to build Diana tanky, she isn't an assassin aka, Kill then Get Out and Hextech Gunblade is near useless in Diana. If you want more DPS get a nashors tooth instead which I see you have added. Also a Rod Of Ages can be quite useful for Diana. HP MANA and AP with the Catalyst passive is all amazing for Diana's laning and overall tankyness. Be sure to add matchups too (simply the ones that will be a problem such as Mordekaiser) and how to avoid getting destroyed would be useful too ;)

Also be sure to add C2V To prevent troll votes and also to gain constructive criticism.

Np Thanks for your time!

Thanks for the +Rep, and now that I actually see it ( and tested it out ), your right about Nashor's Tooth being more viable in the jungle ( or if a person plays Diana like an AP/assassin/fighter ... like me ), thanks for clearing that up :)

Thank you for replying and putting some constructive criticism. I appreciate it and gave you +Rep. I completely agree with you on the Abyssal Mask on how it is both defensive and offensive, and quite a useful item both in team fights and bursting down someone. I will add this in my build and update the build. However I don't see how Nashor's Tooth is an item I would build, unless you are jungle. I can see it help ALOT if you have Red so you can slow enemies on ganks. And with the slow you can burst them down with Your q and follow um on auto attacks. Thats the only thing I see it being viable option. If Diana is playing mid than I don't want the attack speed. Because if I push I cant escape easily with ganks. Again, good option if you are jungling for faster clearing and for ganks, but top and mid it may not as much an option I would want. However if you do have a tank, and you are top, and you do have 21/9 masteries, and you are doing well in lane. I would definitely get it. I will not be adding Nashor's Tooth to the build, but will add Abyssal Mask. Also I forgot to mention that Lich Bane adds burst like Nashor's Tooth for poking and extra substain due to extra mana. Thank you for replying. Will check back for comments Daily.

Hi there SirWhiteKid, I've been playing Diana for well over 50 games (not nearly enough to criticize or downvote any build or guide) now and since I got her I have been experimenting allot and found that Liandry's Torment isn't that great of an item for Diana (sure the health and passive are nice, but it doesn't give allot of AP, and once Diana falls back in AP she stuggles ... allot), another item or two you might want to add in a situational column is Nashor's Tooth (it gives a fair amount of AP, it increases attack speed which will proc her passive Moonsilver Blade quicker, it gives CD and deals bonus magic damage on each basic attack) and Abyssal Mask (it gives a nice amount of AP, Magic Resist and it's passive means that when you do your burst combo on a helpless victim their reduced magic resist means that you will finnish them of sooner and without fear of retaliation) ... Again this is what I've been noticing and doing while playing Diana and it in no ways means that I'm right, please expand build/guide and really PLEASE don't add a vs. column, because it all depends on the player behind the champion ... again thanks for creating a guide/build, there are so few for this massively OP champion ;)
