K'chunk is a foolish ork who got into a fight with General Bre'egth and was beaten for it. You are required to pick pocket him to obtain a tooth of Bre'egth, one of the three ork generals. After/during the quest you can relight the fire he is near, with 8 willow logs to create an everlasting fire. This requires 85 Firemaking and gives you 10,000 Firemaking experience. This cannot be done with temporary boosts. Lighting the fire is required for completing the Fires Are Mostly Harmless achievement.
Also, you can repair the nearby bridges to create a shortcut, requiring 8 planks, 16 nails (any type), and a hammer (this includes both bridges).
(Note: There are two bridges which must be repaired from opposite sides. This means that you must come to the bridges from both the fairy ring side, and the Mos Le'Harmless side to fully repair the bridges).
The update history project is a work-in-progress – not all updates to this topic may be covered below. See here for how to help out!
- When asked if he knows anything about General Bre'egth, he will say, "Soz, I was sleeps and it's gone from me 'ead." The term "soz", is internet slang for "sorry".
