Starting the Quest
"Greeting BOY! I am reporting to you with a mission of upmost importance. Madame Vastra had informed me that a group of clockwork pests have been stealing parts for their pathetic ship.
There is only one solution that I see fit - GRENADES! Come, we will challenge them to a fight to the end!" - Strax upon starting the quest.
Finishing the Quest
"Another victory in the name of the Sontaran empire! I suppose I should offer you my thanks MADAME... or errrrrm... SIR? You proved yourself to be most useful in the midst of the battle. Now would you care for a cup of tea, or possibly some acid?" - Strax upon completing the quest.
Defeat all 30 Clockwork Droids.
