Mountain Giant (Warcraft III)

These monstrous creatures, crafted by the Titans when the world was young, are composed of living stone and stout flora. Benevolent and solitary by nature, the mountain giants have awakened to find that the tranquil world they once helped to shape has become a hectic battlefield of fire and sorrow. Now the mountain giants have pledged their courage and strength to the night elves' cause -- and stand ready to banish the last remnants of the Burning Legion from the world. These massive melee units that can take incredible amounts of punishment from attackers.

Information
Mountain Giants are one of the Night Elves' ultimate melee unit - the other being Bears. Though extremely expensive and taking up a massive amount of food, Mountain Giants are incredibly bulky to make up for this; 1,600 health and several abilities to compliment it.

Taunt prompts the Mountain Giant to perform a yell, forcing all hostile units to target the Mountain Giant and overriding manual attack commands (such as focusing on an enemy Hero). This forces the enemy to reinsert the command again to make their units act the way they wanted them to.

Mountain Giants may also rip a tree from the nearby area and use it as a weapon of their own. The Mountain Giant's attack is temporarily changed to Siege, and also has 200 range. The tree lasts for 15 swings, after which the Mountain Giant discards the tree and attacks with their bare fists.

Make sure to research Hardened and Resistant Skin. Hardened Skin reduces incoming physical damage dealt to the Mountain Giant by 12, and Resistant Skin makes them immune to specific spells and weakens the effects of other spells that would normally last longer on other common units.

aunt

 * All nearby enemies are forced to attack this unit.

ar Club

 * Picks up a tree to give the Mountain Giant Siege damage, and increased attack range. Last for 15 strikes

ardened Skin (Passive)

 * Reduces all attacks on the Mountain Giant by 12 damage.
 * Attacks cannot be reduced below 3 damage.

This means that lower units can't really damage him. You will need to use Tier 3 units such as Tauren, Knights, Bears, and Abominations.

Resisant Skin (Passive)

 * Gives Mountain Giants increased resistance to spell damage.

This gives the unit hero magic resistance, similar to the resistance that level 6+ creeps have. Namely, you can't be Polymorphed, Possessed, etc, and all offensive spells have a shorter duration on the target (such as stuns, Ensnare, etc). It DOES NOT reduce damage dealt to the target, however. That’s an effect of hero armor, not hero magic resistance.
