Annie

Hardly any champion turns a simple kit into kill pressure as well as Annie does. Whether she sits in mid lane or plays support, she is a burst mage with a magic rating of 10, and her damage arrives with almost no aiming required: most of it simply cannot be sidestepped, so fast, slippery targets tend to be her easiest prey.

Her whole kit runs on Pyromania. Once she has cast four spells, the next offensive spell she lands stuns its victim, and she begins each game with that stun already loaded. Every exchange therefore forces the enemy to ask one question: is the stun ready? Disintegrate, her fireball, returns its mana cost upon a kill, so she can farm from a distance at nearly no cost while her passive builds charges in the background. Incinerate sweeps a cone of area damage that helps with clearing minion waves and winning skirmishes, and Molten Shield covers either Annie or an ally, adds a burst of Move Speed and sets fire to anyone who attacks through it.

The Tibbers moment

All of this leads up to Summon: Tibbers. When she drops her flaming bear while a Pyromania stun is stored, the blast deals massive area damage, holds every enemy in the radius in place and leaves a burning, attacking pet behind on the field. A stunned carry caught under Tibbers seldom lives through the follow-up Disintegrate and Incinerate. On support, that same sequence becomes one of the most direct engage tools available.

Annie suits players who like juggling one resource, the timing of her stun, more than players who prize mechanical precision. The downsides are a short effective threat range for a mage and a defense rating of 3, which leaves her with no real escape once her shield and stun have been used.
