- Follow the path marked in red from Arak's south gate to the shovel spot to access Arak's dragon lair. Be prepared to fight several scorpions once you go down.
- Beware, a single Dragon Hatchling might be lured to the stairs.
- Walk over that brown stone and levitate up/place 3 parcels or boxes at the end of the path to go one floor up. Afterwards, walk around to get to the skeleton of the Dragon there.
After you got the key, go back the way you came. Go down. Be prepared to fight a single Dragon Hatchling.
The ground level has a number of Dragon Hatchlings. Beware that if you click the egg then a Dragon Lord Hatchling will respawn.
Once you go down, it is a Dragon Hatchlings cave. Follow the red path.
Rope spot leads to the surface of Arak's dragon lair, north respawn. Here any number of dragons might be lured. But overall, if not lured, it's possible not to even encounter one dragon.
Levitate up and then down. Click the lava spot in order to go down.
Now, use the key you got in order to unlock the quest door.
Now you'd find out the path is blocked by lava as marked in the red circle in the picture. The trick to open the path is to walk over the lava as shown in the pictures, and click the lava hole to turn it on (if it's turned on already then the path is open already).
Now you the path is opened. Go ahead and go up until you reach ground floor. No turns to get lost in. There is only one path to follow.
Beware that one Dragon Lord, one Dragon, one Dragon Lord Hatchling, and one Dragon Hatchling will respawn once someone level 40+ clicks the big treasure chest. The rest of the items on the floor cannot be moved/taken.
