The mighty Lich is one of the best heroes at controlling a lane, thanks to his Frost Nova and Dark Ritual spells. Frost Nova is a strong nuke that slows its target, which gives the Lich a good harassment tool. Repeatedly casting Frost Nova and harassing with physical attacks is a surefire way to quickly bring an enemy hero to his knees. However, Frost Nova becomes even more dangerous when coupled with Dark Ritual. This spell allows the Lich to destroy an allied creep and gain mana based on its life. Using this spell helps the Lich by giving him limitless mana for Frost Nova, and hinders his enemies by denying them any experience or gold they would have gained from the destroyed creep. By using Frost Nova and Dark Ritual liberally, the Lich can quickly force any opponent to retreat from his lane. Later in the game the Lich tends to focus on a support role, using his Frost Armor spell to buff the survivability of his allies, and his devastating Chain Frost to blast his foes in team battles.
