Ahri mana problems

Don't use charm unless you're going for the kill. Heck don't even use fox fire.

How does ahri have high mana issues our spamming to much of your skills

Use as to cs and harass and only use q whenever necessary

those who don't play ahri don't know shit. yea mana cost kind of high for her.

Nope :P

If your spamming abilities you will find yourself low on mama then. Until you learn to manage your mana, go with double dorans and focus on last hitting. Grab meditation mastery and maybe Athene's until you understand how not to spam. But with that kind set up it should allow you to do so if you want to.
