Could anyone tell me where any of the following weapons drop?

crystaline sword, serpent axe, brute sword, ghostly staff? thanks

Crystaline sword - HoH (chest)
Brute Sword - Magmuma Jungle and Underworld
Ghostly Staff - Underworld

there are many other threads on this... scroll down on Q&A and u will find 2 pages of Crytalline sword related chat.
serpent axes have been found from pre-sear to kryta to the shiverpeaks.. just strike lucky.
