Passage

Once a player earns The Survivor achievement in their run, they will unlock the ability to use a passage when they are at a shelter, which will allow them to warp to a different shelter they have already discovered. Each passage achievement earned allows the player to do this one time, and a particular achievement can be earned again upon starting a new game. When selecting the passage option, the player will be greeted by a dream of the achievement which earned them the passage, followed by a UI which lets them select the region they would like to warp to. Once a region is selected, the player can open up their map to select a specific shelter within that region. After the passage, they will wake up in their chosen shelter. While anything stored in Slugcat's gut will travel with them, anything that they were holding in the previous shelter will be left behind.

Connection to Achievements
A player will earn the ability to use one passage for each passage achievement they have completed in their current save, up to a maximum of ten. Once it has been used, it cannot be re-earned, meaning a player can only ever use 10 passages in any given save file. Note also that some achievements are tied to story events, and do not award a passage for completing. You can check your completed passage achievements and progress towards any particular one in the branches connecting to your current Karma level at the hibernation screen. Achievements that can reward a passage include:
 * The Survivor
 * The Monk
 * The Hunter
 * The Saint
 * The Outlaw
 * The Chieftain
 * The Wanderer
 * The Friend
 * The Dragon Slayer
 * The Scholar
