Lich is a ranged character. His primary attribute is intelligence. The hero is mainly taken as a support. Most effective in the early and mid game.
Lich is a perfect hero for team fights due to the spells that allow him to deal damage to multiple targets at once. Already from the laning stage, Lich is able to harass opponents with the Frost Blast ability. During a fight he can make a selected ally or building more durable with the help of Frost Shield. Sinister Gaze allows the hero to hold an enemy, and with the purchase of Aghanim's Scepter, it will work with several enemies at once. This allows Lich to use the Chain Frost ability more effectively, which can quickly elominate a group of opponents, but in a one-on-one fight, the Lich can also be extremely efficient thanks to the Ice Spire ability, which appears after purchasing Aghanim's Shard.
A few desperate magicians grew bold enough to ambush Ethreain. They dropped him in a pool known for being bottomless. Years later, the necromancer Anhil, on an expedition, found Ethreain and then resurrected him. The necromancer realized his error only the moment Lich opened his eyes and with a flick of his finger tore the wizard to pieces.
