If we're to find out what's going on down here it looks like we're going to have to fight our way through the entire Deadmines! Glubtok the Foreman will be the first major foe you encounter, a powerful ogre magi. Be careful, he possesses the brute strength of his race backed by his wicked spellcasting!
Take this communicator so that I can keep in touch with you as we continue our investigation. Be careful down there.
Progress
Yes?
Completion
<Bzzzzzzzzzzzzzt.>
Nicely done! A clean kill. Now continue on and see what else you can find! We'll crack this case wide open with you on our side, I just know it.
This is the first quest inside the instance, offered by Horatio Laine just inside. Clear a path through the elite Ogre Henchmen and non-elite Kobold Diggers. Defias Cannons can be commandeered and used against the kobolds and ogres within line of sight. There are also kegs of Mining Powder which can be attacked to do some AoE damage to the nearby units.
Past the kobolds and their overseers are two elite Ogre Bodyguards, who have an "enlightened" conversation:
Ogre Bodyguard 1 says: Me da best bodyguard!
Ogre Bodyguard 2 says: No, me!
Ogre Bodyguard 1 says: Me got a big board for hit things!
Ogre Bodyguard 2 says: Mine gots a nail in it!
Ogre Bodyguard 1 says: Mine gots a bigger nail!
Ogre Bodyguard 2 says: Mine gots a RUSTY nail!
Ogre Bodyguard 1 says: Dats dangerous.
Ogre Bodyguard 2 says: Only for da bad guys.
Ogre Bodyguard 1 says: But I'm da best at watchin' da door.
Ogre Bodyguard 2 says: No I am!
Past the two bodyguards is Glubtok himself. See his article for tactics and strategy information. Upon his death, Laine will automatically radio in with to complete this quest and offer the followup, The Carpenter.
