Diamond-tipped shovel
The Diamond-tipped shovel is an artefact released in Merentesh's Shop of Wonders in Delos in the year 634AF. It is made almost entirely of steel, including its handle which is etched to resemble wood grain. However, the very edge of the shovel's blade is sports a coating of liquid diamond.
The purpose of the shovel is to cut any duration required for digging by 50% (except in the case of a treasure hunt world event).
