Lich

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