Rune-locked Doors
thumb|Map of waterlogged room. Opening the doors involves slotting Runestones into them until all of the Round Depressions are filled, activating the teleporter. You can only carry one runestone at a time, and you will lose it if you die or use a waypoint. Each door requires the same number of runes to open as its order; that is, the first door requires one rune, the second door requires two runes, and so on. With the exception of the first door, all the runes you need can be found within the previous room. Once you have a runestone: Leave the room and find the next room. This will be true of each room: Take a runestone and leave, Find the next door, Insert the runestone, Return for the next runestone until all are found. To quickly return to the higher level of Derelict Delve after exiting rooms located on lower levels, jump off the ledge and fall/glide onto the teleporter platform half-buried in the lava in the southwestern corner of the chasm. 1000px Note: All doors can be found in the main hallway.
You can only carry one runestone at a time. Using waypoints will make you lose the runestone you are carrying. Logging out or switching maps will make you lose your progress towards opening a door. Doors that have been unlocked will stay unlocked, though. Teleporting to a friend will remove a door progress. Once solved, all rooms will become permanently accessible through teleports at any time, no runes required. This is account wide.
