Teleporter

The Teleporter is a unique circular Interactible located in all main Environments. The orange particles it emits can be seen from a distance. Finding and activating the Teleporter are major objectives in each main stage.

The Teleporter allows you and your team to travel to the next Environment when fully charged.

There are about 12 set spawn zones for Teleporters on each Environment, though some may result in the Teleporter to be partially hidden in dark areas or even found clipping through terrain or objects.

Teleporter Event
Activating and completing a Teleporter Event is the primary mean of advancing the game.

Initiation
After locating the one and only Teleporter in the stage, interacting with it will start the Teleporter Event. A message "You activated the Teleporter" appears. Multiple Monsters spawn immediately, along with the Teleporter Boss to defeat. A red dome appears, demarcating the effective area of the Teleporter, locking any Interactible outside its radius. The Teleporter begins to charge, indicated by the objective "Charge the Teleporter(% progress)".

Teleporter Boss
Not to be confused with Bosses, a tier of Monsters

The Teleporter boss usually consists of one or several Bosses, depending on the difficulty and number of players. Occasionally, a Horde of Many will appear in place of the boss(es) upon activating the teleporter, spawning several Elite monsters instead, scaling with difficulty much like a standard boss.

Bosses and Elites spawned by the Teleporter and counting as the Teleporter Boss can be identified by their distinctive red health bar.

Completion
In order to complete the Teleporter Event the Teleporter Boss must be killed and the Teleporter must be fully charged.

The Teleporter charges as long as you are in its dome. Once the Teleporter is charged to 99%, no more monsters will spawn naturally in the current Environment. The charging rate scales linearly with the number of players standing inside the red dome, out of the total number of players currently alive. Charging the Teleporter requires a minimum of 90 seconds if all players alive always stay within the red dome.

Once the Teleporter is fully charged and the Teleporter boss is dead, the red dome will disappear and interactibles on the map will be unlocked. Any Orb orbiting the Teleporter will form its corresponding Portal. Interacting again with the teleporter will take you to the next main environment.

Drops
One random Uncommon item will drop from the Teleporter after the Teleporter Boss has been defeated. Occasionally, the drop can be replaced by a Boss item corresponding to the Teleporter Boss that spawned (this can only happen for Beetle Queens, Wandering Vagrants, Stone Titans and Grovetenders).

In multiplayer one item will drop per player, even for dead players.

The number of items dropped can be increased by completing a Challenge of the Mountain.

Orbs & Portals
Achieving specific actions before starting the Teleporter Event will spawn Orbs that will orbit around the Teleporter. Upon completing the Teleporter Event, each Orb will transform into its corresponding Portal, leading to different Hidden Realms.


 * A Blue Orb will spawn when activating a Newt Altar. It also has a chance to randomly spawn at the beginning of each stage. It will transform into a Blue Portal leading to Bazaar Between Time.
 * A Golden Orb will spawn when activating an Altar of Gold. It will transform into a Golden Portal leading to Gilded Coast.
 * A Celestial Orb will spawn on every third stage (Rallypoint Delta/Scorched Acres) after the first loop. It will transform into a Celestial Portal leading to A Moment, Fractured.

Multiple Orbs can be spawned on a single Teleporter, allowing for multiple Portals to spawn. However, players will only be able to use one of the Portals (or the Teleporter itself).

Challenge of the Mountain
Main article: Shrine of the Mountain

Upon activation of a Shrine of the Mountain, the difficulty of the Teleporter Event will be increased by the spawn of additional bosses and/or by turning bosses into elite versions of themselves. In counterpart, upon defeating all the bosses the players will be rewarded with an additional copy of each item dropped by the Teleporter.

A level can spawn up to four Shrines of the Mountain.
