Summoner's Spells

Ignite
Ignite serves as an extra source of damage to help finish off an enemy Champion.

Flash/Ghost
Both Flash and Ghost can be used to evade enemy attacks in order to survive or to chase after fleeing Champions to finish them off.

Items
As a caster, Ability Power (AP) is Annie’s primary stat to focus on. 

Sorcerer’s Shoes
These boots will help provide the necessary Magic Penetration to inflict additional damage on Champions that have magic resist.

Rabadon’s Deathcap
This item will give you a major increase to AP and help make your spells even more lethal.

Rod of Ages
If possible, purchase this item before the 15-20 minute mark. Rod of Ages adds permanent health, mana, and AP until it reaches its cap. Getting this item after the 20 minute mark may mean you are unable to get its full effect before the match is even over.

Pyromania [Passive]
After using five ability spells, Annie’s passive, Pyromania, becomes active. Once Pyromania is active, Annie’s next spell with stun any target hit by her next spell.

Disintegrate [Q]
Farming and last hitting will be an easy task for Annie by using her [Q] ability. Killing a minion with Disintegrate will refund the mana used to cast the spell, allowing you to use it freely to last hit minions without the fear of running out of mana. Annie is an excellent mid-lane champion that becomes a deadly weapon once you are able to purchase her items. Annie’s [Q] ability should be the first ability you max out.

Incinerate [W]
Incinerate deals AOE damage to all enemy targets in a cone in front of her. This is Annie’s next main damage spell and should be maxed after Disintegrate. This spell can be used in conjunction with Pyromania to stun a group of enemy targets.

Molten Shield [E]
A shield that increases Annie’s armor and magic resist for 15 seconds, Molten Shield is the last spell you will max out. Although, you will want to max it out last, you will want to get at least one point into it at Level 4 or 8 to help you build charges for your Pyromania stun.

Summon Tibbers [R]
Annie’s ultimate, Summon Tibbers, will summon a large bear at a specific location that will do AOE damage on summon and additional AOE damage to enemies next to Tibbers. Before a potential team fight, you will want to make sure you have Pyromania active, or close to active. Once the team fight begins, you will want to Summon Tibbers on a group of enemy players to both stun them and to inflict as much damage as possible.

Farm/Farming
Farming is to collect gold through killing minions. By farming more gold than opposing champions you have the ability to buy better items quicker to become more powerful.

Feed/Feeder
A feeder is a player that is killed repeatedly by enemy champions. When a champion kills another champion they receive a bonus set of gold. Feeding an enemy champion will mean that they will have more gold to buy more powerful items faster than you or your team. Fed champions will quickly become very powerful and extremely hard to deal with.
