Seperate your starting items in Early, Mid and Late game, put it all into the Items section and explain them accordingly.

Athene's Unholy Grail could never be an item for Annie, even as a Situational is also a no, Annie isn't even mana hungry anyway, Morellonomicon is an better item on Annie than Athene's Unholy Grail.

Abyssal Mask is also not recommended though, Annie's abilities are all range means that you won't even get near the enemies anyways. Void Staff is a better choice, Abyssal Mask is only for some AP champs like Lissandra, Katarina etc. Their abilities goes into the centre of the fights.

Seems nice though but you still have a lot to improve.

Good Luck ^^

Thanks for posting a comment on my guide ;) Since I just created this guide, it's not very complete and I'm updating pretty often. I'm going to explain Masteries, Runes and Skill sequences asap, and match-up/synergy later :)

If you're going to post a guide, you should try to make it as complete as possible. A few suggestions as to what you might want to add:

• A Pros / Cons list. Why is Annie a viable support? What about her is weak and need to be brought to the readers attention?
• Explanation of skills. I know a lot of people with different skill sequences, so you must defend your choice. You could go into a whole new section about possible situational sequences. For example, if you're being pushed to tower and being poked to death, or maybe if you already destroyed lane and are roaming and destroying other lanes as well.
• Another section you might want to consider is an explanation of Masteries/Runes. Why are these good with Annie? How do they benefit her abilities? Do they provide survivability? Utility? Pure damage?
• Lane matchups, maybe? Seeing as Annie support isn't very well known as of yet, newcomers could have a bit of an edge knowing what their strengths and weaknesses are against other more popular supports.
• Last, pictures! :D Make your guide interesting to look at! Make it fun to read! In other words, just make it look nice. The overall appeal of a guide is greatly increased when some really nice coding is used to organize it.

Hmm... Well, I guess I'll just end there ^_^ I hope you take everything I've said into consideration, but you (of course) are not required to actually change anything, as this is your guide. Good luck and may fortune favor your guide!
