Disintegrate is Annie's wepon to good farm. When you last hit with disintegrate you don't lose your mana and you get one closer to get your stun. You get stun ever fifth attack, so when you use disintegrate to get stun you mat interupt the other teams chapion. You take Disinterage to stun him, then incenerate to do more damage. After you have used incenterate you run away from him so he can't attack you back. When the campion you are fighting against got 50% hp you may flash, take disintegrate, incietate, ignite, don't use autoattack run against his tower, and use disintegrate so much you can.
