Anivia is one of the most powerful champions in League of Legends but very difficult to master.If you want to play a good character that not many people choose to play,then anivia is the right one for you.With a little patience and lot of practice you can become a very decent anivia player and be the one who makes the difference between a lose and a win!

BURST DMG!!!!!
Many crowd control(stun slow and wall)

Very slow character

For runes i choose to go with Greater mark of insight x9
Greater seal of focus x9
Greater quintessence of insight x3
Greater glyph of focus x9
The blues and yellows give me some cooldown reduction which is very very important with anivia cuz you attack hard only with 2 skills flash frost and frostbite which means that these 2 skills have to be up whenever its possible.
Magic Penetration is very good with anivia cuz she can destroy almost everyone with her burst dmg and her penetretion.

Masteries i follow the standar caster build with 9 points in offense and 21 in utility so i can take the magic penetretion and movement bonus as long as mana regen cooldown reduction.

For summoner spells i choose cuz they are soooooooooooo good for any caster they give you the opportunity to chase or escape so you can never die or get many kills.That suits best anivia cuz she is very slow.If you want more offense flash ignite is very good too

First you buy the and 2 pots.When you go back to base you have to buy your catalyst of the protector and the if you can afford them.If you have spare money buy some heal pots(mana pots aint needed cuz you must have the blue buff)The next time you go back to base you must sorcerer's boots and the .If you can afford buy kage's lucky pick.Then you complete your and start your .If you face any difficulties complete your first and then the deathcap and the .If you complete the item set buy all the elixirs and the oracle potion and be cool :p :)

In this section i will present you the champions that u have to be afraid of and the ones u dont have too be :):)(Keep in mind that these advices count for a medium-good skilled player)
Easy champions
, , , , , , , , , , , , , , .
If you face one of these opponents your job is easy at around 6-8 lvl you have to get at least 3-4 kills.They are all squishes (except gragas but gragas does dmg mainly with barrels which can be very easily dogded)
Medium-tricky champions
(he is a bit tanky and he has his shield nothing special if he use his ultimate you will have your egg so dont be afraid] (when she gets lvl 6 is a really pain in the **** cuz she can rush to you and do some nice dmg) (She has a very good damage output early on especially if she has correct runes but she is still very very squishy) (nothing much to talk about if he plays tanky is easy just avoid the spikes and be care of his feast if he plays ap then try to land some flash frost from afar to harash him cuz he has silence too) (Ez is squishy but has some nice skillshots and his ulti which can give you some problems.) (That little ninja can do very good dmg and got a stun at 3 marks so keep that in mind) (this rock its very durable and with his seismic shard can harash you pretty good.He has his shield ofc) (she can harash you very good with her spear and also has her own heal ability) (The only advantage that a sivir has is her shield.She can avoid your flash forst and also destroy your combo so attack when she used her shield)
Very difficult champions
(Corki can completly crash you with his rockets and his damage if you are near him.He also has the valkiriye and can escape difficult situations for him.Attack him very carefully best option is to ask for help to take him down.) (karthus is a very squishy champion BUT he can harash you with his abilities and in case he dies he can still attack you for some seconds and of course he can requim you and kill you Try to get him at around half hp and then flash into his face and kill him with your combo) :):)(keep in mind that if you have your egg form up you will not die)
(this one is one of your biggest nightmares.A good kassadin can destroy you in 3 secs he can silence and teleport to safety my advice is to farm and get kills from ganking in other lanes.Play him very smart and try not to feed him cuz if that happens its gg) (Katarina can do high amounts of damage with her ulti and harash you with her dagger.Play passively and make her attack you keep your flash frost to interupt her ulti and then you have the upper hand and probably a kill. (kog'maw has the slow and his ultimate which can harash you from far away.Try to get some kill before 6 lvl cuz when he reaches that level it is very difficult to kill him)(remember his passive he will chase you down if u kill him so try to attack him when your egg form is up.) (A malzahar player wil ltry to silence you put a malefic vision on you and then ulti you if you let him do that to you you are dead.Try to avoid take damage from him in order to survive his ulti.If u get him around half of hp he is dead with a simple combo just keep in mind that his ulti is a disaster and the silence too.) (she is a great harasher and pusher a clever mf will try to harash you and get kills early on.The only thing you have to do is to try to hit her with a flash frost from afar and harash her a bit.If you do that and succeed she will back off a bit.If she does not do that then flash in her face flash frost her forstbite and kill her.) (that tiny dude will play passively and try to build his ap up.HE has the stun and the burst dmg esspecially with his ulti.You must kill him early on around 3 lvl when you will have 2 ranks in flash frost and 1 in frostbite.If you do that he will be more careful and with low hp so he will recalls and lose exp and ap or he will stay and you can easily kil lhim with your combo+flash.) (Vladimir maybe is the best mid laner he has no mana self heal and of course his pool which can avoid your flash frost and destroy your combo try to kill him before 6 lvl cuz when he reachs that level will be very very difficult to do that.In order to kill him try to get some help from another lane.)

Early Game

You grab your crystal and the potions and head to mid cuz this is your best lane.try to last hit minions with auto attack until level 3.When you hit level 3 you can harrash enemy champions with flash frost and frostbite.If you get them around half health flash into melee range flash frost and frostbite and they will die and get u a kill.
Mid Game
When you hit level 6 you go to your blue golem spot kill it and take the buff.When you do that communicate with the other lanes.If they have problem go and gank.Ganking with anivia is easy.You open up ghost cast your ultimate so the enemy cant dogde flash frost and then use frostbite in addition your allies will attack too so 1 kill is guaranteed.Then you go to your lane and continue farming and ganking.
LATE GAME
Well late game your job in teamfights is too 2 hit K.O. other carry's.Sneak behind the enemy team hide in bush and NEVER BUT NEVER initiate a fight if u do that u will die and your team will lose the fight.A pro anivia shines in teamfights cuz she can seperate the oposing team with her wall granting her team some free kills in 2vs5 situations.Otherwise if u fail that part use your ultimate and flash frost and try to stun multiple targets.

Lets talk a little bit about farming with anivia.First of all its very easy all you need to do is to get blue buff and use the combo of your ulti and your flash frost.This combo will destroy one minion wave after another and give you plenty of gold.

So this is my anivia's build.When you play anivia like that you can pwn everyone cuz you have very good damage output and can survivalbility. Thank you for reading my guide hope it helped you:):) Vote and comment thanks :) :)
