Welcome to this 3 AM extravaganza on multiple litres of red bull.
AD Annie is the second most op build in the entire game. She has everything you could ask for: long range, powerful aas, tankiness, cc and a cute teddy bear.
Her kit is superior to almost all the other champions in this game. So make sure to play her the right way. Lately there are a lot of trolls telling you to build ap. Don't let them fool you. AD Annie is absolutely unstoppable as long as there is no Ivern in the match. Build these items, sit back and enjoy the show.

Annie is an absolute powerhouse especially when played AD. She has insane AA range and her base damage on spells will keep the enemy away from you.
Try to harass the enemy as much as possible and try to prok your rune for damage.

AD Annie is a strong mid game ADC-Bruiser-Assassin. Save your stun and deliver the poor souls called enemy team some juicy crits. If your ahead don't be afraid to take risks since your a literal beast if ahead.
If your behind you're lost since it's hardly possible for that to happen for the mighty AD Annie.

AD Annie rarely reaches late. Most of the times you will overpower the enemy before 30 min.
AD Annie is played like any other hyper carry late. Exept for positioning. You don't need that. But take care since only few can comprehend the enormous power behind this Champion.
