Rocks are mineable scenery located in the first level of Underground Pass after old bridge. A pickaxe is needed to mine the rocks for rocks items that can be used to cross swamps safely in the area. File:Rocks.png A minimum mining level of 3 is required as a reward from Plague City quest that must be done before Biohazard and Underground Pass. One scenery object may be mined for potentially infinite number of rocks but doing so yields no mining experience.
