Bar Door

The Bar Door can be found on the back wall of the Grim Guzzler in Blackrock Depths.

How to open
There's three ways this door can be opened:
 * 1) A rogue can pickpocket Plugger Spazzring for the Grim Guzzler Key.
 * 2) Completing the quest The Love Potion (quest) and having Rocknot leave with Mistress Nagmara.
 * 3) Or simply giving Rocknot 6 Dark Iron Ale Mug and causing Phalanx to be attackable, which will destroy the door when Phalanx is destroyed.
