my first guide
This is a very simple and effective way of building and learning ahri. when it comes to 3v3 and 5v5 make sure you have a good tanky backing team so you can get in and blow some faces off.
For runes i use a very simple AP dmg rune page, 9 Magic Pen marks, 9 Flat AP Seals, 9 FLat AP Glyphs, and 3 Flat AP Quients.
My masteries for Ahri are bassed on Burst dmg and a little utility i go for a usual 21/0/9 build taking everything for AP damage in the Offensive mastery tree, and taking Mana regen, increased Buff duration for the occasional blue buff given during 5v5.
Now for items on Ahri i build her like i would any other burst AP dmg Player, i start off with a dorans ring, immediately getting boots, then will of ancients, then straight to Rabadons cap, and last but not least ending it with Lich Bane and if possible Void staff.
For Ahri i like getting a point in Q first and maxing it by lvl nine, while grabbing W a lvl two and maxing it second, and last max E seeing as its a useful utility spell only!!!, also grabbing your ultimate like any other at lvl 6, 12, and 16.
For summoner spells i usually choose Flash ignite depending on team compasition and what lane if i am forced to go mid i sometimes substitute Ignite for clairty keeping flash for quick escapes.
This is my very first build that i am publishing i hope you enjoy and learn alot about a fast and effective way to lvl and play a Agressive Ahri.
