|Examine|| An inventive dwarf assistant.|
Doc is a dwarf who is the starting point for the Invention skill, and serves as the Skill Tutor. He claims to be an assistant to Drorkar, but Drorkar dislikes his refinement and innovation-based style of thinking. He sells the Invention cape to players who have achieved level 99, and the Invention master cape to players who have achieved level 120.
Players who wish to augment dragon and crystal tools already on their tool belt may speak with Doc, who will remove the item from the tool belt. He will only perform this service once per tool slot.
2017 Christmas event
During the 2017 Christmas event, the Doc helps by creating a power generator which is used to attempt to first bring the clockwork gnome to life by itself and once again along with Aubury and Orla Fairweather's methods.
- His name might be a reference to the character Doc from the Back to the Future movie franchise. He also shares some physical similarities with the character, too.
