Oldak is the greatest inventor of the Dorgeshuun, an advanced tribe of cave goblins. He spends most of his time in his house in north-western Dorgesh-Kaan.
Oldak is known for his excellent magical skills, a trait uncommon amongst the cave goblins. He seems to view magic somewhat like a scientist; his home is filled with lab coats and strange metal instruments, such as the oojimaflip and magic balls. Only after Dorgesh-Kaan's opening was he able to do much; the lack of available runes in the hidden city made things difficult.
Moving-over-distance spheres[edit | edit source]
Oldak will make players moving-over-distance spheres, if provided with molten glass (noted and un-noted both work) and two law runes. He then proceeds to coat the molten glass in the crushed law runes, and when the glass is hardened, the orb has magical properties. When broken, the orbs will teleport players to one of several random areas in Dorgesh-Kaan.
During Another Slice of H.A.M., he will also make players goblin village spheres. After the quest is complete, he will make players these spheres in the same way as Dorgesh-Kaan spheres.
Also, if a player inquires about the magic he has discovered, the cave goblin will explain some of his more recent discoveries, which will temporarily raise, or lower the player's Magic or Runecraft skill by up to two levels.
Talk to Oldak. Ask, "What have you discovered?" You will get a different response depending on what skill is affected.
Runecraft boost - Oldak lectures you on the construction of runes and you find yourself thinking about Runecraft with greater clarity.
Magic boost - Oldak lectures you on the magic energies stored within runes and you find yourself thinking about Magic with greater clarity.
On the top floor of his house is a chest which can be opened with a lockpick if a player has a Thieving level of 52. The chest can be opened once every 3–5 minutes, and the loot obtainable from it is different from the loot of the other chests around the city.
