Armed robbery was probably not the best idea to pay for this trip although if you find any treasure then at least you can live the rest of your life in Brazil. You go on the hunt as soon as you arrive.
Resteem found.

You find an abandoned shack. Inside you discover a shovel but not just any shovel. This one feels super light and makes you feel energized
Legendary Shovel +1 Coordinate Dig per day
You can now dig 4 coordinates per day instead of 3

G17 - You head up into the hills north of the docks and all excited, you start digging .... nada

Q22 - Unhappy with this area you try the hills to the west of the docks and start digging .... nada x 2

Z11 - On the boat journey in, you noticed a human skull like cliff face. You go north and find it. Climbing to a grassy ledge on what looks like the right eye, you start digging ... nada x 3

W3 - You head north into the mountains. You have to be lucky this time surely???? ..... nada x 4

Ah well, better luck tomorrow.
