Two Worlds

The Fire Element rests in the heart of Gor Gammar, the Orc stronghold far to the south. Unless you are very powerful, you'll want to head to Cathalon before you attempt to penetrate the fortress.

To get inside, you'll need to take a cave, this cave is located to the left alongside the city wall if you are looking at the giant as doors to the city.

You will obtain the Fire Element at the city of Gor Gammar

There are multiple ways to get inside the city, but this solution uses a tunnel just outside the walls. You will have to survive/fight off a lot of enemies, but I did this at Level 41 and had no issues at all.

-Getting inside Gor Gammar-
Gor Gammar is the walled stronghold at the south center edge of the world map.

Gor Gammar is marked as #5 on this map:




Along the Eastern wall, just near the corner, you will spot a dark cave entrance. You may also see some enemies just outside of this place. Enter the "Dungeon"

-Inside the Dungeon-

The interior of the dungeon is extremely dark and difficult to navigate, so you will probably want to hit START, and then go to SETTINGS and turn the GAMMA CORRECTION setting up so that you can actually see.

Navigate your way thru the dungeon to the point on the map in this picture (check spoilers tags if the link is dead)

Visual of the area:




If you are at the point but don't see the exit, keep searching, you will find it right nearby, perhaps on a lower or higher area. It's not a big area so just keep looking.

-Inside Gor Gammar-

Now that you are inside the city, just navigate around the corner and over to the structure that is on the Middle Southern wall of the city. Inside this building you will see the Fire Element. Grab it and the achievement is yours!

Be sure to activate the teleporter inside the city so that you can return quickly if you are going for the Visited All Locations achievement
