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 near by to save them. Unlike most heroes, he doesn't 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 sets on, granting him power to decimate any target. Inner Vitality magically heals Huskar after he is injured, regenerating health each second based upon its primary attribute, and heals more when the health is on a critical level. It can be used to heal allies as well. 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 HP 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.

Tips

 * Remember that Huskar becomes more powerful with less health, but can still die. Figure out when enough is enough.
 * You can use Inner Vitality on yourself before jumping into a fight to counteract the damage you take.
 * Burning Spear and Life Break both use up health, and feed your Berserker's Blood.
 * Remember that Burning Spears will stack on an enemy. Switch it to auto-attack and burn them down!
 * Life Break lowers the target's current HP to 1/2 (1/3 if upgraded), and lets Huskar jump to his target immediately. Consider between chasing a wounded enemy and dealing damage to a tough one.
 * You should be warned not to use your ultimate on a hero who has an active magic immunity or else you lose a percentage of your health while the target does not. However, the slow will still pass through magic immunity.
 * Huskar's Berserker's Blood increases your survivability significantly. At 30% health, and level 4 Berserker's Blood, you have 83% magic resistance, allowing you to keep your HP in place while taking physical attacks if you have lifesteal and decent damage from items.
 * Black King Bar is important to keep in mind on Huskar since you don't lose a percentage of your health when you use your ultimate, and allows you to kill magic-based Heroes like Lion without the risk of death.
 * Some players only skill Burning Spears to level 1 (for early harassment), and then go on to max Berserker's blood and pick up an early Morbid Mask (later Helm of the Dominator and eventually Satanic). You will absorb more HP and deal more damage the lower your hp is, and the Helm of the Dominator is a great tool for jungling, but ever since latest buff to Burning Spears, this build (or not taking the skill at all) is considered outdated.
 * Huskar is effective at dealing with lone targets, but often time struggles when enemies are grouped up. Don't get too cocky, even if you can take on anybody on the enemy team. It's usually best to let somebody else initiate, and then come into the fight when the enemies are spread out, that way, you can take them on one at a time and most likely win each of the duels.
 * Use Inner Vitality before you use Life Break because Inner Vitality has a fairly long duration.
 * While with Berserker's Blood Huskar is nigh impossible to kill by spell casters, be very cautious of pure damage and HP removal. Dealing with heroes such as Bane and Timbersaw can result in death, as using Life Break in their presence can have dire consequences, since their spells aren't reduced by magic resistance.
 * Also beware that despite his agility gain Huskar's armor is relatively low even until the middle stages of the game and thus if your ultimate is used carelessly the enemy team will only require one or two disables to allow their own carries to kill you. In this respect you must pay special attention to heroes with long duration disables such as Bane, Alchemist, Shadow Shaman, Dragon Knight etc.
 * As Life Break deals Magical damage to an enemy relative to his current HP, it is possible through damage amplification to kill any enemy in one hit provided it is not magic immune or has access to very high Magical resistance (e.g. Spell Shield).
 * It is possible to use certain combination of items and heroes together with Huskar to kill any hero instantly. For example applying the effects of Veil of Discord, Ethereal Blade, Orchid Malevolence to a target and then hitting them with an Aghanim's Scepter upgraded Life Break will cause an instant death. However building all these utility items onto Huskar himself will destroy a great deal of his carry potential. This same effect can be achieved using 's Soul Catcher instead of Veil of Discord or 's Decrepify instead of Ethereal Blade.

Trivia

 * Huskar's name might be derived from the old Norse word "Huskarl", the title given to the highly-skilled bodyguards of important Norse lords and kings.
 * His name might also be derived from Huáscar Inca, a leader of the Inca Empire in the 16th century. Huskar's lore also connects him to Dazzle, who is a Shadow Priest (Fits in the Native American shaman role).
 * Before 6.79, you could use a Ghost Scepter and then manually cast Flaming Spears on enemies. You would take little Magic damage since the Magic Resistance provided by Berserker's Blood reduced the incoming magic damage significantly.
