Hey guys.
This is my first guide so dont harrass me with what is wrong and what is right.
Ive decided to make a guide for Anivia because i play her alot, and alot of people have asked me to make one.

Pros:
Alot of burst both late, mid AND early game.
Good stun for ppl like nunu and carries.
Good aoe
Very well farming
Good wall to both interrupt enemys and save teammates
Have a very nice egg, if you die from a caitlyn ult behind you turret for example.

Cons:
Squishy ealry game if you dont buy that Dorans Ring.
Can look up yourself or teammate with wall ^^
Gets focused alot in teamfights

Marks:
I take Magic Penetration marks because it makes a very big differents in the whole game.

Seals:
I take Mana/5sec/level because it helps alot early game and mid game.
If you want more defence the whole game you could take flat armor instead, theyre good because lots of ppl arent using their spells on you when youre an egg.

Glyphs:
I take flat ability power because they help alot early game so i can push the enemy mid away from his xp and gold.
You can also get CD reduction/level glyphs, they are better in late game because you can harrass alot more.

Quintessence:
Í take flat ability power again because they give a very big dmg output early game with my glyphs.

I put 9 in offence so i get the 15% magic penetration because it gives alot more dmg both in early and late game.
And i take the standard 21 caster point sin utility because it helps me give a lot more dmg to the enemy.

I take FLash and Ignite because flash can help me move very fast into a battle, flash away when im getting chased, flash if im rebirthing from my egg while there are somebody attacking me and im very low and get over my wall if i failed it :D
I take Ignite because it helps me get kills in low level if theyre faster than me, and im putting it on theyre carry in team fights so that his going fast down because hes only gettig half heal.

I start off with a Dorans Ring because its giving alot off ap and hp early game.
Then i build a Catalyst because it gives good mana and hp, and i can stay in lane very long time. Then i go for my magic pen boots, i take magic pen because it gives alot more dmg than any other boots will give. Then i upgrade my catalyst to a Rod of ages fast, because i will get the 10 min. stats before the game are over. I then go for my banshees, so i can out dmg theyre ap carry in 1n1s and in teamfights. Then i build a rylais because i get alot off hp and ap, and the slow helps my whole team because when we go into a teamfight and all of the enemys a standing in one big circle i just put my ult down and they cant get out so easily.
I then get my void staff because many of the enemy tanks build alot of magic resist to counter me.

This is how i play Anivia.
Lvl 1: Only last hit and try not to use mana, but if the enemy is aggresive put a stun down to cancel their attacks.
Lvl 2-5: Try go in and use stun and then E, but remember not to be too aggresive.
Lvl 6-11: Now you have to be aggresive but try not to be ganked, put out some wards and look if there are any misses on the other lines.
Lvl 12-18: Try be with your team all the time, be careful not to go alone. Get so many kills and assists possible.

Thank you for wathing my build. Please rate and give a commet below :-)
