The legendary Horadric cube, found in Act II's Halls of the Dead (Dry Hills), can be placed into the personal stash to add extra storage. The cube itself only takes up 4 spaces but has a 12 space capacity when opened *Note: Be careful not to press the transmute button when doing this. The unique Viper Amulet, also found in Act II (Claw Viper Temple in the Lost City), can be retrieved a second time even after the Horadric Staff is completed and used to open Tal Rasha's Tomb. It serves as a really good amulet, especially on the Normal skill level, but does not compare to amulets found on Nightmare and Hell difficulties.
