Every 18 seconds, Lissandra's next ability costs no mana. Cooldown reduction does not affect Iceborn, but the cooldown is reduced by 1 second whenever Lissandra impairs an enemy's movement with an ability (does not apply to movement-impairing effects from items).

Cost: 85 mana
Active: Throws a spear of ice that travels in a line and shatters when it hits an enemy, dealing magic damage and slowing its movement speed for 1.5 seconds. Shards then pass through the target, dealing the same damage to other enemies hit (but not slowing them).
Active: Casts a claw of ice that moves forward in a line, dealing magic damage to all enemies hit. Reactivating this ability transports Lissandra to the claw's current location.
Active - Enemy Cast: Freezes target champion solid, dealing magic damage and stunning it for 1.5 seconds.
Active - Self Cast: Lissandra encases herself in dark ice for 1.5 seconds, becoming untargetable and invulnerable but unable to take any actions.
Dark ice then spreads from Lissandra's target dealing magic damage to all enemies in the area as it expands. The ice lasts for 3 seconds and slows enemy Movement Speed by 20%.
