A new plaything!
Henzell says...
  1. Timed portal vaults: {bailey}, {bazaar}, {ice cave}, {labyrinth}, {ossuary}, {sewer}, {volcano}, {wizlab}. Do what they say on the tin. Basically, a single-level branch (can be large or small) which you can only enter once, and which will eventually disappear. See relevant page for each portal.
  2. see {portal distance}

Information based on master branch and the great LearnDB.
