An Ender Pearl Stasis Chamber, also known as a stasis, is a redstone contraption that enables long-distance, instantaneous teleportation. Stasis chambers typically work by suspending a thrown ender pearl in a bubble column until it is triggered by coming in to contact with a block- often a trapdoor or piston.
Mechanism
Basic Principles
An ender pearl will only teleport the player that threw it once it comes in to contact with a solid block. Stasis chambers take advantage of this mechanic and by preventing contact with a solid block an ender pearl can be kept in stasis indefinitely. Most forms of stasis chamber use a soul sand bubble column to keep an ender pearl suspended in water, though honey and slime blocks can also be used.
Stasis chambers also benefit from two additional characteristics of ender pearls. Thrown ender pearls persist across sessions, and so an ender pearl will not be lost if a player disconnects from the server. Additionally, ender pearls are chunk loaders and allow redstone circuitry and certain other mechanics to continue functioning even when no player is nearby.
Activation
For a player to be teleported, their suspended ender pearl must come in to contact with a block.
Manual Activation
The simplest stasis designs require a second player to manually interact with the device, often by activating a trapdoor that triggers the ender pearl.
Remote Activation
Remote activated stasis chambers are more complex but allow players to use a stasis chamber independently. Most remote activation designs use the owner of the ender pearl logging in to the server as a trigger.
Frost Walker
Until December 2025, frost walker designs were the most common type of stasis chamber. They used armour stands with frost walker boots close to a water source to detect logins. When the player joined the server, the frost walker boots would freeze the nearby water, which would be detected by an observer. To prevent the stasis from activating every time a login was detected, a piston was often used to immediately break the ice- allowing for multiple, successive logins to be detected.
Most frost walker designs used two logins within a set duration as the trigger for activation. Initially hopper clocks were used, but due to a server change that made hopper clocks inconsistent, repeater based clock designs were popularised from September 2025.
Pet Obby
With the switch to Folia in December 2025, frost walker stasis chambers were no longer able to function. Pet obby was introduced as a vanilla-like alternative to frost walker and serves as the basis for all current remote activation stasis chamber designs.
Pet obby stasis chambers are unique to Legendary Hardcore and work by the player looking at an obsidian block and executing the command /petobby. Once an obsidian block has been 'tamed' it will turn in to crying obsidian when the player is offline (returning to obsidian when the player returns). An observer next to a pet obby can detect these block changes, allowing for logins to be converted to redstone pulses.
History
The first manual activation stasis chambers appeared in early March 2025 and relied on cooperation with a second player to interact with the ender pearl.
On the 11th of April 2025, Kosmiau revealed a design for a remote activation stasis called the Multiple Location Teleportation Device (MLTD). On the same day, Kosmiau used four stasis chambers to travel around the four world border corners in under 45 seconds. This design appears not to have used timed logins per stasis chamber, but a system of indexing so that each successive login moved the player to the next corner.
Stasis chambers became increasingly common in April and May 2025 and enabled players to easily travel to and from the Spawn Region without extensive travel. By June 2025, monkebillions had pioneered a simplified frost walker stasis design and shared a tutorial[1] on how to build it, making it the most popular frost walker stasis design at the time.
In September 2025 a server change to the behaviour of hoppers broke many existing stasis chambers. Several alternative designs were proposed and a repeater based alternative created by Spalmipede proved popular.
The transition to Folia in December 2025 broke all frost walker stasis designs and pet obby was introduced as an alternative method of remote activation. nefunguje_0, ShyAlly and Spalmipede created and shared a design that is now in use by almost all users of stasis chambers.
