Lich

Lich is a ranged support hero that uses his skills to slow his enemies down with his frost-based attacks, as well as giving a boost to ally defenses. He can use Sacrifice to easily deny creeps and keep his mana high, making him very good at harassing in the early stages of the game. While a relatively frail hero, he can prove to be a force to be reckoned with when his ultimate, Chain Frost, is used on a group of enemies. Lich is a powerful crowd controller and can easily turn a teamfight, or dominate in a lane. Lich is recommended for beginners.

Basic Strategy

 * Spamming Frost Blast and Sacrifice early game can be extremely effective by harassing and denying efficiently.
 * An effective strategy is to take Sacrifice immediately. Even though you won't need the mana earned from it, you can deny a creep immediately to prevent the enemy from earning experience and to pull the lane towards your tower.
 * Despite primarily being a support hero, Lich can play a very effective mid. Combining his powerful Frost Blast to harass the enemy while denying his own creeps can shut down the enemy's laning phase.
 * Ice Armor is a very cheap yet effective ability. Cast it on nearby allies to keep their armor up, or yourself to increase your own survival.
 * Keep in mind that Ice Armor can be set to auto-cast, automatically casting it on heroes that are are attacked.
 * Chain Frost can be one of the most devastating ultimates in the game, and can easily turn a teamfight in your favor when used properly. Each time it hits, it deals very high magic damage and bounces to another random enemy unless there are no targets nearby. Use it to deal damage quickly to clustered Heroes.

Trivia

 * Lich's voice actor, Gary Schwartz, also voiced the Heavy and Demoman classes in Team Fortress 2, another title by Valve. Lich's lines, "UM NUM NUM" refer to a line said by the Heavy class in Team Fortress 2: the first is an alternate to "OM NOM NOM", used when the Sandvich Edible Device is consumed.
 * In the transition from DotA to Dota 2, three of Lich's skills have had their name changed. Frost Blast used to be called Frost Nova, Ice Armor used to be called Frost Armor and Sacrifice used to be called Dark Ritual.
 * Lich's original name was Kel'Thuzad, a reference to the character from the Warcraft universe.
