Anivia

Anivia is a control mage for the mid lane whose entire identity revolves around zoning enemies out of space they want to occupy. With a maxed-out magic rating of 10 and a difficulty of 10, she is one of the hardest mages in the game to pilot well: her damage is enormous, but every part of it demands setup, mana management and precise positioning around her 600 attack range.

Her kit is built on combos rather than single spells. Flash Frost sends a slow-moving sphere of ice that chills enemies along its path and stuns in a radius when detonated. Landing it unlocks her real damage: Frostbite deals double damage to targets recently hit by Flash Frost or standing in a fully formed Glacial Storm, her ultimate that rains ice over a wide area while slowing everyone inside. The classic sequence — stun into storm into doubled Frostbite — deletes squishy targets and shreds grouped teams in choke points.

Terrain control and safety

Crystallize is what separates good Anivia players from great ones. The temporary ice wall blocks all movement, letting her cut off escape routes, split teamfights in half, or seal a jungle entrance. Her passive, Rebirth, turns fatal damage into an egg state from which she revives with full health, punishing enemies who dive her without the resources to break the egg.

Anivia suits patient, cerebral players who enjoy controlling teamfights like a chessboard. Her weaknesses are clear from her stats: an attack rating of 1, heavy mana hunger and no mobility mean she is immobile and vulnerable once her wall and egg are down.
