Lissandra/Strategy

Skill usage

 * You can instantly use on yourself by pressing the self cast key and the ultimate key at once (alt+R by default).
 * Casting and then running in the opposite direction will leave your enemies uncertain which way you will actually go.
 * Try to cast in a position where it would hit the most enemies to maximize the damage and slow.
 * In team fights, use at the enemy in the center of the enemy team to deal a decent amount of damage to them.
 * Alternatively, you can use to blink to the center of the enemy team and use  to disable them immediately giving your team free hits and then self-targeting  when the stun is finished to prevent the enemy team from retreating or retaliating at you.
 * 's cooldown will be 17 seconds instead of 18 if the spell it is affecting impairs the movement of an enemy.

Build usage

 * abilities are shorter range than those of many mages. As a result, buying items that offer both ability power and defense, like and, can be a great choice to help her both survive and deal damage.
 * Cooldown reduction is very strong with suite of crowd control abilities.
 * combined with passive Mana Font, Lissandra will almost never be manaless.
 * Since all of her abilities except for has a movement impairing effect,  passive will almost always deal double damage.
 * will give you a decent amount of ability power, a high amount of cooldown reduction and some mana regen making it a rather good option to buy it.

Countering

 * When is ganking, keep an eye out for her  as she can blink to it's position. Stay clear of it as she can followup with her  to snare you when she blinks.
 * abilities have a rather short range so try to distance yourself away to prevent from being slowed or stunned.
