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 and gain their current maximum Karma in the process. 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 with max Karma. 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: Survive for five cycles in total at your current maximum Karma level.
 * The Monk: Go on for five cycles in a row eating only fruits, vegetables or fungi.
 * The Hunter: Go on for five cycles in a row eating only meat.
 * The Saint: Go on for four cycles in a row without throwing spears or rubbish at any creature. Devouring creatures does not affect progress torwards this.
 * The Outlaw: Kill a number of creatures that are normally unedible to the Survivor or the Monk.
 * The Chieftain: Gain maximum reputation among the Scavengers.
 * The Wanderer: Sleep atleast once within each Region in the accessible world.
 * The Friend: Sleep with a Lizard in a Shelter three cycles in a row.
 * The Dragon Slayer: Kill atleast one of each Lizard breed, excluding Red Lizards, Cyan Lizards and Salamanders.
