Just a quick tip, every achievement in the dlc is for completing the challenge. You choose 5 challenges at the start of the expedition limiting you to 5 achievements per attempt. If you do not have the challenge selected yet you complete the requirements you will not get the achievement.
As for this achievement, I recommend doing this achievement along with the achievements for surviving 5, 7 and 10 days and escaping after 7 days.
This can be done on any difficulty.
The card setup I used was:
Unlimited poison arrows
Tomb Raider (Grants all skills)
Tool Chest (Grants all tools and large pool of resources)
Bloodlust (Killing enemies grants a small amount of food)
Hot Blooded (Killing enemies grants a small amount of warmth)
You should be able to find 10 artifacts easily within the first 3 crypts you encounter.
This should take less than 3 days, in order to pass the time I found an enemy camp cleared it and stood next to the open fire. The animals and enemy's that happened to pass by were enough to keep my hunger up. (If you kill an animal you do not have to eat it straight away the body will not despawn)
Once you reach the 11th day you can light a signal fire and escape. It takes around 2 hours to reach the 11th day.
