• Once downstairs, search all the chests until you find the goblin kitchen key (most commonly found in south-eastern part when you go down the stairs, don't skip the dialogue once you find the key or you will not pick it up. If not found in the two chests directly south-east from the stairs, it is guaranteed to be in the last chest in the dungeon. The other chests will contain poisonous spiders.).
• Head north from the entrance in the dungeon, then go west to the kitchen gate and prod the sleeping guard, then kill or trap him.

• Head back into the goblin dungeon.
• Run past the kitchen and climb up the stairs in the south end of the dungeon. (During the cutscene, DO NOT CLICK on anything in the observatory or you'll have to restart the cutscene)
