Demon Hunter (Warcraft III)

Demon Hunters are dark, shadowy warriors who are shunned by the greater Night Elf society. They made a pact, long ago, to fight against the forces of chaos using its own terrible powers against it. These mysterious warriors ritually blind themselves so that they develop 'spectral sight' that enables them to see demons and undead with greater clarity. They wield demonically charged warblades in battle and even call upon demonic energies to augment their formidable combat skills. Although they are counted as some of the mightiest warriors within the Night Elves' society, the Demon Hunters are always maligned and misunderstood for making their selfless pact with darkness.

Information
The Demon Hunter's main focus is to hunt Demons, but he's also great at fighting other Heroes! Fans of custom Hero Arena-maps have discovered that the Demon Hunter is one of the best Hero-killers. He is one of the toughest melee Heroes and also has the Mana Burn ability, which instantly takes away mana from enemy Heroes that could be otherwise be used against you. Mana Burn also reduces the health of the enemy Hero, which softens them up for you to finish off. He can remove 150 mana with a level 3 Mana Burn. He can also use Evasion to reduce the amount of damage received, use Immolation to damage several enemies at once and later become very powerful with Metamorphosis.

To use the Demon Hunter effectively, players will need to control him well. He can be very weak against focused-fire ranged units or melee units that surround him, thus it's important to use hit-and-run attacks and to run away whenever the enemy focuses their army on him. Other ways to keep him alive is the Druid of the Claw's Rejuvenation and items such as Healing Potions.

The Demon Hunter is very good at Creeping at the start of the game. Use him to take out powerful Item-dropping Creeps, grab the item, and run back to Moon Wells for healing and more mana. You can even lead Creeps back to the Moon Wells and fight them there. He is also an excellent rusher when it comes to destroying buildings and killing enemy workers.

He is also one of the best Heroes to have if an enemy Hero rushes you at the start of the game. When the enemy approaches, you can Mana Burn them, which will greatly reduce the amount of damage they can do against you. You can also combine this with the Detonate used by Wisps to further take away more mana. Refill the Demon Hunter with the nearby Moon Wells and continue to use Mana Burn.

Experts are divided when it comes to spending points on the Demon Hunter. Some argue that Immolation is a waste for early Creep-hunting since the Demon Hunter can just heal back up using Moon Wells. Immolation can still be good against tightly packed units, especially if they try to surround and kill him. Some prefer to spend points in Mana Burn, then Evasion and continue placing points in these two until they reach level 6 for Metamorphosis. Others prefer to focus on Immolation and Evasion, and some like to spread the points around, with some in Mana Burn and some in Immolation. One option suggested by TillerMaN is mixing Mana Burn and Immolation since higher level Mana Burn generates a reserve of unused mana.
 * Spending Points

He becomes even more powerful with Metamorphosis, which yields a 500 hit point bonus, splash damage, and faster Hit Point Regeneration. His attack range also increases to a long range, and his damage type changes to Chaos Damage. Chaos damage does full damage against all types of armor.

The Demon Hunter is weak against the Dread Lord's Sleep and the Keeper of the Grove's Entangle. Still, it is possible to use other units to wake him from Sleep, Moon Wells to refill the health lost by Entangling Roots. In a duel with a Dread Lord using Sleep it's important to Mana Burn him before he can use it. If he still manages to pull it off, wake up the Demon Hunter with an Archer or a Huntress. The Demon Hunter is also slightly weak to the Mountain King's Storm Bolt, but this can also be countered using Moon Wells and Mana Burn.
 * Demon Hunter Counters and Downsides

One downside of the Demon Hunter is his lack of an Aura. This can make quite a difference in large team games. In later stages of the game you should take advantage of a second hero with either Thorns if they have a lot of melee units or Trueshot Aura for your Huntresses, Archers, or Dryads.

He needs a lot of support with Archers, Dryads, and Huntresses in order to distract the enemy so he can sneak in and clean up.

Mana B urn

 * Sends a bolt of negative energy that burns a target enemy unit's mana. Burned mana combusts, dealing damage to the target equal to the amount of mana burned.

Mana Burn is best used against enemy Heroes. You can also use Mana Burn against annoying enemy spellcasters such as Priests, Sorceresses, or Shamans.

If you use this ability against enemy Heroes, you will not get the full amount of damage due to Hero Magic Resistance. Some Creeps and units also have resistances to this ability.

Make sure you check the mana of the enemy unit before using this ability. If they are already low on mana, it's not worth to Mana Burn them and thus waste the Demon Hunter's own mana.

This spell has little chance of being countered. To prevent Mana Burn you need to either have Spell Immunity, kill the Demon Hunter, or hope he runs out of mana himself.

Immo l ation

 * Engulfs the Demon Hunter in flames, causing damage to nearby enemy land units. Drains mana until deactivated.

Evasion (Passive)

 * Gives the Demon Hunter a chance to avoid attacks.

Evasion is a very powerful ability because it allows the Demon Hunter to avoid attacks and take no damage. You should always try to max this ability.

Since this is a passive spell requiring no mana, this spell has little chance of being countered. The best counter is to have more units attacking the Demon Hunter.
 * Evasion Counters

Me t amorphosis (Ultimate)

 * Transforms the Demon Hunter into a powerful demon with a ranged attack (60 range) and 500 bonus hit points.

This ability is very powerful because it increases the Demon Hunter's hit points by 500 and gives him a very fast Hit Point-regeneration. He can also attack with a ranged splash damage attack. You should use this ability in heavy combat whenever possible.

Run away until the spell wears off, quickly kill the Demon Hunter with massed units, or use a Hero-killing spell or ability.
