(U6O)-Treasure Maps
So, you want to find some buried treasure, eh? Alright then, adventurer, let's get cracking!
First you need a treasure map and a shovel. Treasure Maps come as loot on dead monsters/"evil" NPCS. Shovels can be purchased from various provision shops, or even found.
When you look at the map you get a paper minimap with a red x that shows the general area where the treasure is buried. It should be about in one screen area from the x. Fans of the original Ultima 6 will recognize the Treasure Map minimap is based on the original cloth map that came with the game.
To dig you need to equip a shovel, and then use the map on the ground. (Pick up the map with your cursor, then hit U to then target the spot your want to dig/search.)
You don't have to hit the exact spot, because there is a Two Square tolerance, so digging in one spot actually "digs" a 5x5 square area.
It will say "NOTHING!" if the map was not used on the correct spot.
After digging around some time, you will hopefully hit the right spot, and a treasure chest will pop up. It will be locked / magically locked. There is a high chance that the items found in will be + items.
