The cave goblin tech tree is a tree of technology from Invention. At level 40, you may choose to follow this path by talking to Oldak in Dorgesh-Kaan.

Cave goblin technology tree items can be unlocked using Cave goblin currency which is earned by completing Invention tasks (not to be confused with Daily Tasks). These tasks can be found at the noticeboard in the Invention guild, near Oldak in Dorgesh-Kaan, and near Drorkar in Keldagrim. Up to 5 tasks can be saved and each 12 hours a new task is added.

The cave goblin tech tree is as follows:

Tier Level Invention Unlock Cost

RuneFest 2015 - Invention cave goblin tech

At RuneFest 2015 the following device concepts were shown as examples of items that could be included in the cave goblin tech tree:

  • Stealth module - would make the player's minimap dot appear as that of an NPC.
  • Dungeoneering Automapper - would automatically reveal the map for a Dungeoneering floor. During a developer stream, it was revealed the Dungeoneering automapper was mostly scrapped, as the developers were not fond of how it was designed along with its implementation and testing time.[1]
  • Flash bomb - would stun one pickpocketable NPC and increase the success chance for pickpocketing. A similar concept was introduced with the soul-in-a-box.
