World Event

World Events are activities that appear in public areas, and change with each new expansion. Completing world events rewards to the players with loot and other materials.

Destiny

 * Blades of Crota - The World Event for The Dark Below was that every ten minutes or so on Earth or the Moon, the Hive would summon a Blade of Crota. Killing the Blade would drop an Ascendant Sword that the player could use to kill the Hive that would spawn shortly after. This event counted towards two of Eris Morn's daily Bounties.


 * Wolf Packs - House of Wolves reintroduced the Queen's Wrath, retooled as a Bounty hunter activity in which players could collect Bounties on Fallen targets that would arrive by Skiff to public areas on Earth, the Moon, and Venus. These Fallen always came in waves; the first wave would drop a small group of Fallen and two Scorch Captains. Killing the first wave would initiate five more waves; on the last wave, the Bounty target, typically a Wolf noble, would appear. Killing the target would not only complete the Bounty, but also cause an Ether Chest to appear somewhere in the area. The player had one minute to find the chest and unlock it for ammo synthesis, planetary materials, and a chance at a Treasure Key.


 * Taken Lieutenants - In The Taken King, Taken will periodically certain areas. Certain of these Taken are Lieutenants—Major Captains, Knights, Minotaurs, or Centurions. Killing three Lieutenants before the Taken retreat will summon a Taken Champion, an Ultra-level enemy. Killing the Champion is a requirement for certain Taken War Quests, and have a chance to drop Runes, as well as Relics that can be returned to Banshee-44.

 * High-Value Targets - A special enemy will appear somewhere in a public area, accompanied by a brief on-screen notice. Guardians must eliminate them before they depart. This enemy is usually a Major, but can be an Ultra or an Elite, and can even be followed by a squad of its fellows. Successfully killing the enemy will yield a chest containing Glimmer and a reputation token. An Engram may drop from the enemy itself. This event occurs in all locations, with enemies of the faction present there.


 * Enemy Patrol - In any location, a group of Minor enemies led by a more powerful combatant (usually an Elite) may appear in a slightly hidden part of a public area, with no message to announce them. Occasionally a player may need to kill a few waves before the leader comes. Killing the leader and then the remaining troops will make a chest appear containing common gear.


 * Enemies move against each other - A message can announce that two enemy factions have started fighting each other. They will keep sending stronger and stronger troops as the battle goes on, eventually becoming outfitted with Absorption Shields, as if the Shielded Foes Modifier became active. The belligerents will retreat after some time, signaled by a message. While there is no chest reward for this event, it is a good place to find large amounts of powerful enemies. This event occurs in all locations where two factions hostile to each other are present.


 * Fallen Scavengers - A Skiff will drop off a crew of Fallen Scavengers with two Sentry Servitors. The Fallen will scatter across the area, while the Servitors will move to guard a locked loot chest in the vicinity. If both Servitors are destroyed before the Fallen Scavengers finish their scavenging, the loot chest will unlock and reward Glimmer and a reputation token. This event occurs in the European Dead Zone, New Pacific Arcology and on the Moon.


 * Roving Pikes - On worlds with Fallen presence, a message can announce that a gang of Pikes piloted by Pike Dregs is starting to roam an area. They will engage with any foes they encounter, possibly disrupting a Public Event, but continue on after a while. While defeating them doesn't give special rewards, it allows players to use the Pikes for themselves.


 * Roaming Interceptor - On worlds with Cabal presence, a message can announce that a Psion piloting an Interceptor is starting to roam an area. They will engage with any foes they encounter, possibly disrupting a Public Event, but continue on after a while. While defeating them doesn't give special rewards, it allows players to use the Interceptor for themselves.


 * Jump Gates - On worlds with Vex presence, a series of Jump Gates may appear around an area, guarded by Quantum Vex. Defeating a pair of combatants will activate their jump gate, which will launch the player towards another group of combatants guarding a gate, and so on, eventually returning to the first gate. Once a full lap is completed, Storm Minotaurs will appear at the gates, alongside other troops. Each Minotaur killed will drop a chest, as if they were High-Value Targets. This event occurs on Nessus, Io and Mercury.


 * Prisoner Exchange - On worlds with a Vex presence, such as Nessus, Io and Mercury, a Minotaur Guard guarding an energy cage with an Ultra will appear. This event also occurs on Europa, were a Storm Minotaur guards a cage imprisoning an Elite Fallen. Eliminating the Minotaur will drop nothing, but will make the energy shield around the prisoner disperse, releasing it. Defeating this enemy will drop a loot chest which could contain reputation tokens, engrams or pure loot. In Flashpoints, sometimes the health and loot drops of the prisoner were increased, or more enemies were added to the cage. For example in the Mercury Fields of Glass prisoner exchange, three Psion Flayers joined the High-Value Target in the cage. After a while, the Minotaur and its prisoner will disappear.


 * Flashpoint Bosses - During a Flashpoint, additional enemies could spawn, near Public Events or World Events, such as the War Hound. These units will have a significantly large health pool and when defeated will drop loot, glimmer, reputation tokens and possibly engrams.


 * Supply Retrieval - This event occured only during Faction Rallies. For the duration of a Rally, the Red Legion or House of Dusk will drop four supply crates which will be guarded by standard troops and Retrieval Specialist Incendiors or Stealth Tracker Marauders. Capture each crate to earn a faction token. Once three out of four crates are captured, a Quartermaster Colossus or Vendetta Shank Heavy Shank will arrive to defend the fourth crate. After all crates are captured, a loot chest will appear with Public Event-level rewards. This event occurs in the European Dead Zone, New Pacific Arcology, Arcadian Valley, and Echo Mesa.


 * Vex chest - On Mercury, a group of Vex led by Sentry Harpies may appear in an area alongside a locked chest, and start fighting incoming Cabal. Defeating the Harpies unlocked the chest, though during Flashpoints, doing that would summon the Terminus Keeper as additional protection.


 * Escalation Protocol - The event could be triggered on Mars by activating any of the Rasputin-themed towers scattered around Hellas Basin. The participating players have to defend themselves against several waves of Hive, ranging from Thralls during the lower levels and Ultra Knights, Wizards and Ogres during the higher levels. Some waves will include the added challenge of having to locate and disable Shadowrifts by standing within them and shooting Hive crystals, similarly to the Witches' Ritual public event. When all the crystals have been destroyed, a Severing Knight will spawn which will drop a Cleaver when defeated. There are a total of seven levels, with the seventh one featuring a boss with unique mechanics that rotates weekly.


 * Locked Chest - In the Tangled Shore, a message may announce that a group of Scorn has appeared in an area, guarding a locked Chest. This squad is comprised of several Elites, led by a Major Corrupted Chieftain. Defeating the Scorn will unlock the chest for the player to plunder.


 * Invasion Blight - In the Dreaming City, an unshielded Blight may appear in an area, unannounced. When it is damaged, it will begin spewing enemies, starting with Taken Acolytes, then adding Ravenous Taken Captains, and finally calling forth a Blighted Centurion. Killing the Centurion will yield a chest containing Dreaming City gear. The Blight will remain until it is destroyed or its timer runs out, and will keep generating enemies, though the Centurion will not return.


 * Double Trouble - In the Dreaming City, in the Divalian Mists, near the entrance to the Blind Well, there are three stone circles. Every once in a while, they will start glowing. If three players stand in the circles, Paradii, The Vigilant and Bakken, the Relentless will appear. Killing them will reward the players with a triumph and Chests containing Dreaming City gear and Dark Fragments.


 * Taken Saboteur - In the Dreaming City, in the Rheasilvia area, a Farseer's Saboteur may appear, announced by a specific message. Killing it will allow the player to use its charge to eventually unlock a chest containing Dreaming City gear.


 * Manifested Nightmare - In the public areas of the Moon, an Ultra Nightmare Ogre (formerly the Nightmare of Gothrax, Swarm Protector) may appear in phantasmal form, announced by a personalized message, with a chest nearby. Once a player moves close, it will take shape and attack, summoning allies. Defeating the Ogre will complete the event, and unlock the chest for plundering.


 * Vex Invasion - This event occured during Season of the Undying, on the Moon. After a Public Event was completed, the Sol Divisive would open a gate and send in an invasion force. Waves of Vex would start pouring in, led by a Gate Lord. Killing the Gate Lord would make the Vex retreat and start another invasion in the same area. When three Lords were killed, the invasion would stop and players would be awarded Powerful Gear. If enough Angelics were killed in each wave, there was a chance an Overlord would appear after the third Gate Lord's destruction. Defeating it would grant Pinnacle Gear.


 * Smuggler's Chest - On Europa, in any public location, there may be a hidden chest. This event has three variations:
 * Fallen terminals may appear in the area, one of which has a sealed chest next to it. Interacting with one of the terminals will give a Data Key (Incomplete) buff with a 45 second timer. One must interact with the other two terminals, which will now be highlighted by pillars of light, to turn the buff into Data Key (Short-Term), which will allow the player to open the chest. Leaving the area will drop the buff.
 * A single terminal may appear in the area, which will give a hint to where the chest is hidden if interacted with. The chest will be invisible, but when near it the prompt to Uncover Hidden Cache will pop up, and interacting will make the Smuggler's Chest appear and open up.
 * A chest in the area may be booby trapped, and interacting with it will give the player a Data Key (Destructive) buff with a 60 second timer. One needs to find the Smuggler's Chest in the area to use the Data Key, or it will self destruct, killing the player.


 * Enemy waiting out the storm - On Europa, in the Eventide Ruins, there is a chance a Technorunner will appear whenever a snowstorm happens, announced by a message. Players that kill this Captain can begin a small quest that leads to Europan Gear.


 * Strange Signal - On Europa, in the Asterion Abyss, a group of Vex led by a Wyvern Venator may appear, announced by a message. Killing the Venator will give the player the "Strange Signal" buff, which allows them to encounter the Friendly Harpy in the Nexus. Though the Venator can eventually respawn, only one Strange Signal quest may be completed each week.


 * Lucent Hive Inquisitors - In the Court of Savathûn, a group of glowing Revenant Hive may appear in an area, announced by a message. Defeating these Hive will prompt their Major commander to appear. Once the commander is defeated, another group will be announced nearby. After three such groups are defeated, three Ultra Lightbearers will appear, alongside some reinforcements. Killing these and crushing their Ghosts will prompt the reinforcements to leave, and award a Chest with World Drops and Qualichor. Your Deepsight will also activate, revealing another chest with better loot that can only be opened with Refined Qualichor. This event happens in any of the three main locations, changing on a weekly basis.


 * Nightmare Chest - On the Derelict Leviathan, a trio of Major Nightmares may appear in an area, alongside a locked chest, announced by a message. Killing the Nightmares unlocks the chest, which yields World Drops and possibly Opulent Keys.


 * Haunted Alcove - On the Derelict Leviathan, one of two Haunted Alcoves per area may become active, identified by a personalized message. The Nightmares within will be powerful and constantly backed up by reinforcements. Clearing all the Alcoves awards the "Fever Dream" Triumph.


 * Leviathan Operations - On the Derelict Leviathan, one of four Events may occur: an Imperial Boarding Party, a Shield Warden with its prisoner, Loyalist Fortifications, or a Nightmare Trinity. These are announced by a personalized message, as well as the lighting briefly turning dark like a Public Event. Completing all these events awards the "A Guardian Is a Guardian, Even in a Nightmare" Triumph.


 * Ammo Sabotage - In all public areas of Neptune a Munitions Psion may appear, identifiable by the antenna on their back. Somewhere in the area, a pack of munitions with a Cabal hologram will also appear. Killing the Psion will make them drop the antenna, which can be picked up and brought to the munitions while under constant orbital fire. Successfully planting the antenna will destroy the ammo and reveal a chest.


 * Legion Surveillance - In all public areas of Neptune, a communicator may appear attached to a wall or panel. A player can interact with it to pick it up and track the signal to its source, guided by the messages on screen that will say how strong the signal is getting. Finding and disabling the communicator awards a chest.


 * Timed Vex Repulsion - In all public areas of Neptune, one may find a translucent Conflux. Interacting with it will prompt five plates to spawn nearby, in randomized locations, but pointed at by beams of light from the Conflux. Shooting all the plates within one minute spawns a chest, while failing to do so calls a Minotaur, which will have to be defeated before the Conflux reforms.
