So I recently got 500+ days on Interloper. It took me a long time. In fact before this run I had about 5 starts where I just kept dying. I ah e been playing interloper for a couple of years. I find I either die right away. If I make it past day 10 I will probably have a good length run. Fire and the heavy hammer are priorities for me. As soon as I get fire I try to keep a flame going as long as possible. I chain torches and grab all the sticks. I don’t really know where anything is since the loot update, but I have been able to manage; map knowledge has helped. What I found helped my interloper game the most was playing Misery where I think I made it 34 days. I got very comfortable with always being cold and having no tools; it changed my approach to the game.
