Skull of Corruption (Skyrim)

Skull of Corruption is a dream-dependent weapon of different usage than its predecessor during the Oblivion Crisis. It can be obtained in the quest Waking Nightmare, which begins in Dawnstar. At the end of quest one will be asked to kill priest Erandur or destroy the Skull of Corruption. In order to collect dreams to power the staff simply cast on a sleeping person. This is not counted as an aggressive action so they will not attack you. Choosing not to kill Erandur does not make obtaining the Oblivion Walker achievement impossible, as there are sixteen possible artifacts to collect. Note that you still have to keep the staff charged with Soul Gems as well. A good place to collect dreams is The College of Winterhold, as it is easy to get full access and there are lots of people in a small space sleeping during the night.
