Lich

Ethreain, the Lich, is a ranged intelligence hero that uses his abilities to slow his enemies down with his ice-based attacks, as well as giving a boost to ally defenses, and serves as a great teamfight ganker with his powerful ultimate. He can use Sacrifice to easily level up and keep his mana high, making him very good at harassing in the early stages of the game. While a relatively frail hero and mostly known as a support, he can prove to be a force to be reckoned and mighty foe to stand with as he can render the attempts of multiple enemies futile with his ultimate, Chain Frost. Lich is a powerful crowd controller and can easily turn a teamfight, or dominate in a lane.
