Archaeologist's set

The Archaeologist's Suit is a set of vanity items introduced in the 1.0.4 patch. It is made up of the Archaeologist's Hat, the Archaeologist's Jacket and the Archaeologist's Pants. The hat is dropped by Doctor Bones.

These items are all supposed to be equipped in the Social slots as they only provide a visual appearance.

All in all you need 150 Rotten Chunks to craft the whole Archealogoist's Suit.

Trivia

 * It is very likely that the inspiration for these items is a reference to the Indiana Jones series of movies due to word play. (i.e.; Doctor Bones, Doctor Jones)
