Mistress of Ice: Lissandra deals partial true damage when damaging brittle enemies.
Watcher's Gift: Lissandra starts the game with a Shade of Black Ice, a unique trinket item. Lissandra places unique wards when using the Shard of Black Ice, which lasts from 60-120 seconds. These wards are visible and freeze the ground around them, causing revealed enemies around the ward to become brittle. These wards can not cause the same enemy to become brittle twice. Reactivating the tricket while a ward is active will allow Lissandra to cast her next ability from the ward, however, the ward breaks afterward. At level 9, the Shard of Black Ice will become a Shard of True Ice, which grants true vision around the ward for 10 seconds after placing it.

Iceborn Familiar: Lissandra can target allied allied minions or small jungle creature with the Shard of Black/True Ice, causing them to become a pet to Lissandra. Lissandra can only have one Iceborn Familiar at once. While a Familiar is active, reactivating the Shard of Black/True Ice will control the movement and attack target of the Familiar. The Familiar gains bonus health and attack damage based on Lissandra's ability power. When the Familiar dies, it causes all near by enemies to become brittle.

Iceborn Thrall: Lissandra can target an allied champion with the Shard of Black/True Ice, causing them to become an Iceborn Thrall. Lissandra can only have one Iceborn Thrall at once. Iceborn Thralls gain bonus armor, based on Lissandra's ability power. Lissandra can reactivate the Shard of Black/True Ice while an Iceborn Thrall is activate in order to cast her next spell from their position, doing so will break the allied champion of their enthrallment.
