Hello this is my second build my first build is kindda boring but i wrote it on a phone.
AnyHoe This is my Ahri build: Ahri is a Burst/nuker mage with all of her spells.

PROS:

High damage nukes


Great mobility


Great CC

CONS:

Squishy untill rylais


Much skillshots = MUCH SKILL CHAMP :D
[/list]

I get the masteries 9/0/21.
in offence tree i get extra AP and magic pen
in utility tree i get Extra movent speed and shorter cooldown = more spam

The runes if for getting high AP and magic PEN.
this can be chnaged for magic resist if u feel like u getting killed with Spell alot.
or u get armor runes if their Trynamere comes and basic attack u down :/
or u change them for even more ap.
JUST TRY DIFRENT RUNES IF U WANT :D

THE ITEMS
The items is for maximum Burst and AP spellvamp is realy good with the passive thats give her Spellvamp.
AND OF COURSE cna they be changed for magic pen items or extra survive abbility ONLY GET MEJAS IF DOING GOOD OR IT WASTE OF MONEY!!!!!

The skill queue is maxing your first spell first and then your second but always throw the combo E > Q > W > R > Q thast should make a 100% kill but if u miss your combo they can kill u before you reacting but if u hit yours they will be dead :D

One of the most intresting part of this guide :D
The summoner spells i go for on almost every champ is ingite and flash but of course u can eperiment u can get Cleanse instead of flash if they have much CC like taric panteon Sion Trydamere Etc Etc its good to have it but i prefer ignite and flash Try other Summort spells.

This is how u win teamfights
Try to position your self so u can hit theirs carry with your Charm (E) and then Throw Your Q and pop your ulti same time as your W and u will secure kills for u and your carry

Thanks for reading this hope u find this enjoyable and use it well :D
