Dreadspire Keep Access

DSK access involves completing certain missions all over Darkhollow. There's not really a Dreadspire 'arc' per se.

1. Talk to Treddlehoop in Corathus Creep to get "Scavenger Hunting".
*Treddlehoop's Signature Monocle

2. Talk to Brovil Palivineg in Corathus Creep to get "The Lost Notebook". This is the same task as 69.1.
*Spectacular Image Enhancing Prism

3. Talk to Mazil in Corathus Creep to get "Lost Gnomes".
*Gold and Platinum Twined Necklace
*Hivegrime Stone of Willpower (http://lucy.allakhazam.com/item.html?id=83745)
Unresting Fingerbone Necklace (http://lucy.allakhazam.com/item.html?id=83785)

4. Talk to Zahn in Undershore to get "Deserting the Ranks".
*Golden Shiliskin Tentacle Ring
*Korlach Sacrifice Plate (http://lucy.allakhazam.com/item.html?id=83875)
