Notes
Scarab coins are decorative and also used for "sacrifices" (to activate warps) in the several Ankrahmun Tombs. Scarab coins can also be obtained by using your shovel or secret agent tool in the sand in Ankrahmun's desert, but only near tomb entrances and some other places. When having dug on the random square (scarab or scarab coin pops up when you dig it), that square takes 60 minutes to "respawn" to prevent people from farming coins on just 1 square.
