Sometimes it is smarter to approach an enemy with 3 Pyromania charges instead of 4 to appear vulnerable. You can then quickly charge the stun with Molten Shield. It can also allow you to break Banshee's Veil with a weaker spell before using a spell (especially Summon Tibbers) that stuns them.
This can also be an effective strategy to lure enemies into a false sense of security.
As each of Annie's abilities gives a charge for Pyromania this allows Annie to only need 2 or 3 charges when a team fight erupts allowing Annie to be able to use her Molten Shield and then casting your offensive abilities to then land an AoE stun on the enemy team.
During the laning phase, try to find a good balance between storing your stun for use and continuing to use your spells to maintain a strong farming game.
Don't rely on Molten Shield to keep you alive. Its damage isn't great for countering AD carries with life steal, and early game its defensive properties are minimal at best. It is mainly used to charge up a combo.
Always charge up Pyromania before a fight occurs, the 1.75 sec stun is very effective in taking out carries who overextend or out of position.
WhileIncinerate can take down groups of low health minions early game, positioning the cone so that it also routinely damages the enemy champion can be very useful. Dropping their health like this can be followed up with a big Summon Tibbers/Pyromania burst for the kill.
安妮的Summon Tibbers can be controlled, like most pet units, by holding Alt or activating the ability again before moving.
Summon Tibbers doesn't require a line of sight to be summoned, try casting it inside a bush if you know an enemy is there.
Storing a stun for use with Summon Tibbers can turn the tide in her team's favor.
Abyssal Scepter is a great option for Annie when the enemy team has lots of magic damage. It provides magic resistance, but still contributes to her burst potential with AP and a magic resistance reduction aura.
Be alert for the visual effect that appears when the stun from Pyromania is ready.
Because Disintegrate refunds mana when used to last hit minions, be cautious around an Annie using autoattacks on minions. She is likely to have 3 stacks on Pyromania and is waiting for someone to engage her. She will cast Molten Shield, allowing her to stun on her next spell.
Molten Shield acts like a Thornmail. Be careful when engaging her if you are using a champion that relies on auto-attack.
