The first few titles I saw had just a couple of tiers: survivor, drunkard, party animal (I started during a festival, so I had booze and candy before I had a secondary profession). Then I met “Cartographer.” That is normal, an achievement for exploring the whole map. It starts at 60% and tiers up, makes sense.
I did not notice until this weekend that it goes all the way to 100%. This explains much that I have seen in the wiki. Zone descriptions talk about how the docks count as 0.1% of the map, or you can get an extra pixel by “scraping” the walls of a zone, or that 101% is possible. When I was thinking that you were done at 80% or 90%, that seemed super-Completist. Now I’m worried that I need to step foot on almost every square centimeter of the world if I want to add that to the Hall of Monuments.
I am saving that one for once I start trying hard mode vanquishing anyway. I just feel for folks who were stuck at 99.8% and spent weeks scouring maps for the dozen pixels that needed to be stepped on because they had an invisibly brief lag spike one day while pushing against a rock.
