Huskar

Huskar the Sacred Warrior is a ranged strength hero who is an effective ganker and carry, with both great benefits and risks offered. He is known to be a powerful adversary in most games, as his damage per second can easily kill other heroes at any point in the game assuming no one is nearby to save them. Unlike most heroes, he does not use mana much to use his abilities, rather, he sacrifices his own health to inflict the highest damage possible. His passive Berserker's Blood defines the power of sacrifice; he gets more dangerous the more he gets hurt. This gives him increased magic resistance and attack speed depending how much life is missing, and the given magic resistance and attack speed are staggering, potentially having the highest damage output in the earliest stage. Huskar can use his own life force to attack using Burning Spears which scorches foes and gives him an advantage early on. Due to the health cost of Burning Spears, his Berserker's Blood activates, granting him the ability to decimate any target. Inner Vitality magically heals Huskar or his allies, regenerating health each second based upon the target's primary attribute, and heals more when the health is on a critical level. His Life Break is his most dangerous ability and a risky one too. Charging towards his target, Huskar sheds a large amount of life force to cut a target's current health to fractions. This is great to use as an initiation spell, as it deals immense damage based on the target's current health, breaking it down, allowing Huskar and his allies to feel the pain that the Sacred Warrior felt. Courageous and fearless, Huskar is powerful at any stage of the game, and is willing to suffer and face death, for him to contribute and deliver a marvelous victory to his team.
