I've recentlly been playing alot of Ahri. I'm no expert by any means but I learned to play the champ from scratch(no video's or guides or anything) So here is some of my learned advice. In no particular order.
Ahri isnt a 100-0 champ as far as I can tell till late, against squishies. She excells at kiteing and poke though. Whittle your enemy down and either make them back or get them low enough for a kill.
Learn your orb range. Hitting them right at its peak is optimal, because it gives both the reg damage and the true damage right away. If they are closer often they get hit by the weaker exit and dodge the return.
If you dont nail your Charm, its often safer to not go in just yet. Unless you are 100% sure you can kill them anyways, hold off.
Use poke combo's. If you nail that charm, use your Q and W and maybe an AA or two, then back off. She trades will like this, but like I said she doesnt 100-0 well so your enemy will often be alive and dangerous after this, and if you didnt disengage you will get beat up badly alot of the times. Hit that combo, do your damage, then get out.
R is not just or even mainly an offensive skill. Dont be afraid to use your Ult to escape. Use it to jump to the side of a minion wave to land charm then your combo, then use your last R charge to get out safely. The damage on it isnt "ultimate" level, like alot of other champs, its not a huge power show. Its almost more important to use it for the utility and mobility it gives.
FARM. Very important to keep good farm. Dont try to be supper aggresive poking(most times) As her mana costs feel high to me, and all her stuff is skillshots, so its easy to burn that mana. And you really need to get some items to make her start doing some damage later. Take the poke when you can land your combo or sneak a Q onto them, but farm well. (Always should anyways but people are poke happpy these days.
TEAMFIGHTS. Stay our of them (locationally) If you get in the middle of the pile, you will probably die. Throw charms and Q's into closest pile, it will do more damage and help more then you may feel it does. If your R is up and you see an out of position adc or other squishy priority target, Dash around nail a combo and dash back ou. Teamfights are about kiting effectivley for Ahri, staying safe, and just adding damage and charms.
Builds, I generally
, or
if their mid is poke heavy and i want the MR. With all of Ahri's kiting
is good, cause you build up those charges pretty rapidly, and the movement speed is great on her.
Is something I use on her for the CD and more movement speed, the active is nice chasing a kill or trying to get away, has saved my ass a few times. All around there isnt anything wasted on it for ahri.
if they build alot of MR, or any time really, its a great item.
of course. On occasion I build
, the extra mana is nice, also adds movement speed. The passive is eh, depends on their team and you think its safe getting an AA in your rotation.
There could be more effective build paths, this is just what Ive been having success with
