Mabar Endless Night Festival

Update 7 event, 2010 Halloween

Items that can be collected from killing undead: Burnt-out Black Opal, Chipped Skull, Cursed Fingerbone, Ethereal Key, Vampire Fangs, Lich Dust

The opal, skull, and fingerbone are used as trade ins. The dust and the fangs are used for crafting. Trading in either of the trade ins results in motes (as far as I have seen). Motes are needed to trade in for items or upgrade items, many recipes will also require other items such as spectral dragon scales (obtained using the ethereal key when the time is right to be sent into an instance to fight/kill the spectral dragon. Killing him will result in you being rewarded with a scale), lich dust, and vampire fangs.
