Deep within the mountains the forge resides, to access the forge you will need to have completed the gnome set in the Conlegret collecting cards.
The pack of cards needs to be activated in Graves of the Poor or Place of Sorrow, the pack will allow unlimited ports to the entrance of the forge, but the battlefield is only active for 24 hours, and repeatable every 7 days. A group of 1 (or more) is needed to access the instance.
The battlefield consists of three areas, the entrance, a tunnel, and a forge. In the first 2 areas there are Clay  , Stone  and Crystal  Golems, which are adjusted to the level of the attacker. In the third chamber the Fire Golem  lives.
The fire golem has the ability to change his hp and power dependant upon his opponents level.
The fire golem can also cast the following spells:
NOTE: Fiery Heart is transferable till level 12 +
NOTE: Only 30% chance 1 rune will drop.
After the fire golem has been defeated, it will drop 1 fragment of the golem pet amulet.
NOTE: Unwanted parts of the golem pet amulet can be exchange for 30 Gnome Coins each.
Quest to complete the golem pet amulet
After collecting all 5 different pieces go to the Gnome Spirit, take the quest. Gnome will send you to
Soygurna @ Square of Fire or Ostap the Craftsman @ Daylight Square. You then need to get 5 magic clay, from the Clay Golem in the smithy.
However, a simple medallion is not enough, you need to use magic, so you need to take it to Lady Guinevere @ Frontiermarks or Lady Cordelia @ the Domain of Winds. They will tell you about the need to kill the Golem of Marmara to revive the charm.
Go to the abandoned Forge and activate the medallion, the golem will have 1298hp, hit without block 50-70. NOTE: you may need to kill the golem up to 10 times, you will get this message in chat if you are sucsessful:
17:37 The Golem's heavy body falls at your feet, and at the same moment the medallion radiates hundreds of tiny rays, literally capturing the monster's spirit in a net. Received: Reborn Golem Medallion 1 pcs.
Take the medallion to the Gnome Spirit for the reward.
500 experience, received: Medallion of the Golem, 1 pcs
