About the Iron Golem

[The Mob]

Effect: Summon a Golem from a metal item. The golem gains properties of the item.
The Iron Golem's strength lies in his Thorn Damage. This Golem is very powerful against Melee attackers.
Iron Golems can be constructed from non magical items. You will receive the additional Damage listed on weapons, or the Defense listed on Armor. Currently you do not receive the damage benefit for using two-handed weapons.
Save powerful Rare and Magical Items you don't wish to sell, use or trade to create Iron Golems. Some magical item properties are not transferred to the Iron Golem, such as "Chance to find Magical Items" and "Mana Steal".
You can only create Iron Golems from metal items, and you cannot make them from Clubs, Wands, Crystal Swords, Gloves, Belts, Throwing Weapons, Staves, Bows, Crossbows, Quest Items, Jewelry, Leather Armor and Leather Boots.
Iron Golems can gain the abilities of Socketed Gem weapons. When you create an Iron Golem out of an Ethereal Item the Iron Golem is translucent.
