Wormbrain is a goblin who is imprisoned in the Port sarim jail. Players must kill him to obtain a Map piece in order to construct the Map to Crandor and complete the Dragon slayer quest. Because Wormbrain is jailed behind a locked door, players must have a magic skill level of 33 to cast telekinetic grab and take the Map piece which he drops.
* During the Dragon slayer quest
- Later iterations of RuneScape have amended the Dragon Slayer quest so that players may purchase the map piece from Wormbrain, instead of requiring a magic skill level of 33 to cast telekinetic grab
