I would like to note that the endgame statistics are not including the multiplier from Rabadon's Deathcap. I don't know what is up with that, but rest assured, I have played this build before and it results in 620-800 AP with all items and buffs and consumablles, not 422. Strange that the difference itself is close to -273 (The temperature of Absolute Zero) when using Deathfire Grasp.

I am by no means a pro, but through out the games that I play, I almost never lose mid. In fact, there are two instances that I can recall losing. One did not beat me in kills, but took my turret first and that would be Soraka (Makes sense, when you think about it), and the other Beat me in kills but I took their turret first and that would be Cho'Gath. I have no problem dealing with the likes of Talon or Kassadin. There are some champs like that, where you cannot risk coming out from under your turret until you know they are sufficiently on cooldown...so don't. (Typically tough match ups are champions with a quick silence and a gap closer) Eventually the enemy will get impatient and make a mistake or get ganked by your jungler. If they start leaving lane alot, it's a good idea to use wards to make sure you can return to safety in time and push your lane out while they are elsewhere. This of course will draw them back to where they should be. Don't follow them to the lane they are attempting to gank/assist, unless your team requests it or you feel it is going to be a 4/5 man gank. Remember, Anivia has poor mobility, so you have to make game decisions based around that fact...you cannot keep up with most other champs, so don't try to.

With Anivia, you may be slow, but there is no excuse for getting caught out of position. You have three seperate tools at your disposal- Q, W and R to help you run away. Use the R to get that little bit extra away from someone like Xin with a gap closer. Use the Q to stun anyone who has caught up or is gaining on you. Use your wall in appropriate narrow passageways or once they are caught up. it is almost always enough to get away, unless they choose to use a flash just to catch you. (A lot of players get so sick of Anivia escaping that they will start to make stupid decisions just to shut you down...which is hilarious when you make it under a turret and revert to egg form and your team finishes them off instead) Oh, I forgot, you have flash too...don't ever use your flash unless all other options are on cooldown.

Pay attention to HOW you are missing WHEN you are missing. Often it will be that the enemy takes a step back. This requires a small adjustment to what direction you fire your shot in. Fire right behind where the enemy is standing.

If they take steps to the sides (a more advanced dodge) then you will have to decide which way they are going to travel which is often something you can deduce based off of minions health bars. They are going to approach low health bars of friendly minions to get farm, so be ready for that and fire in that direction instead of straight at them.

Very few people step forward to dodge, since it makes them so much more vulnerable to other attacks, so if they do this, make them pay for it with your ult and follow that up with your E.

Whenever you land a Q, try to be close enough to pull off an E at double damage, but dont do it if it puts you in danger. The Q+E or R+E combo will punish enemies for even the slightest mistakes.

If you cast crystallize under an enemy turret with enemies present, it will start shooting at you, so be careful.

Use crystallize for vision of bushes, etc. whenever you are suspicious, but once it is on cooldown, play passively and very carefully.

Don't be afraid to use crystallize to attempt to trap someone in a bush that you dont have vision of. I can't tell you the amount of times I have luckily trapped someone picking up a kill for our team just on a whim.

Use crystallize to trap an enemy in your ult for a just a little longer...sometimes that's all you need for the kill.

Farming is a little tricky for pre-ult Anivia, but Anivia will ALWAYS catch up. So don't EVER put yourself in harm's way because you are falling behind. EVVVVERRRR! You will always end up on top if you continue to actively farm the entire game.

The honest best advice I can give is to remember not to starve your team mates of farm. Anivia can gather wave after wave of farm, but when you see someone else trying to farm on your team, get the creeps low, and turn your ult off and walk away. This is a team game and Anivia can sorta get greedy if not watched carefully.

So By end game, you have three moves Q, W and R that protect you. You have Zhoyna's to become untargetable, Seraph's Embrace to become shielded and Guardian Angel to revive you AND your egg to revive you. Anivia can last through an extremely long team fight if played properly. I think that by playing to her strength of a phoenix's rebirth and filling her inventory with items that are similar, you create one very unique and dangerous adversary. Time the Zhoyna's early in the fight, to divert focus momentarily. Save the Seraph's embrace for when you have been revived from your guardian angel. What you have become is a catch 22 for the enemy team. They can focus you which may result in them taking you down, at the cost of losing the team fight or they can not focus you and let you single handedly win the team fight.
