Public events are the third type of patrol activity within Destiny 2, and the only patrol activity returning from the original Destiny. These occur at specific areas on each destination, and their location can be seen from the map.
Not only that but after a short amount of time they can be manually started by interacting with the flag located in the area. These can vary from destroying a fallen walker to taking out waves of enemies.
Most public events have a Heroic modifier that can be added to the event if a specific set of actions are performed during the event. Triggering a Heroic Event will increase the difficulty of the event, but it will also boost the experience gains and loot rewards at the end of it.
Below are the triggers for each Heroic Event.

This event is new with the Curse Of Osiris Expansion. It is found on Mercury and has guardians killing Vex Gatekeepers and slamming Arc Charges to open the middle area with a Gate Lord Boss.
To trigger the heroic version, once the Gatekeeper has been killed on the first island, instead of going through the man cannon go to the back and start shooting down the Vex Crystals as you make your way to the top of the island to activate a Vex Portal.
This event is usually found on Earth, and has Guardians repel a dangerous Fallen mining operation. To complete this event normally, players must kill the four marked Elites guarding the drill before the time runs out.
To trigger the heroic version, destroy the extractor – the small devices that beam light to the drill – at all three drill sites.
On Titan you can often catch Fallen attempting to transport weapons. When this event occurs, three Scorch Cannons will spawn behind shields and you’ll need to eliminate an Arsenal Walker tank.
To trigger the Heroic version of this public event, you’ll need to simply unlock all the Scorch Cannons. Dealing enough damage to the Walker will expose it’s “neck” and temporarily stun it. It will then drop 3-5 Arc Charges that need to be deposited into the generators on either side of the shields surrounding the cannons.
Place one arc charge in each generator to disable the shield and unlock a Scorch Cannon. Once all 3 are open the event will upgrade to Heroic status and another Arsenal Walker will be transported into the field – worry not, though, these new super weapons will make quick work of them both. It’s not necessary to use them, but they do help.
On Nessus, you’ll encounter a Vex construction event. To complete the event normally, you need only defend against the incoming Vex and prevent them from reinforcing their structures belowground. To add the Heroic event, you’ll need to do a bit of extra leg work.
The central Vex structure shoots out three beams of light which can be followed until you find a circular plate with a pole in the middle. Stand on the plates as you would on a control point in The Crucible and capture each area for yourselves. Be aware this will spawn several elite Vex enemies as well as a Hydra construct.
This event tasks you with capturing a mining lander while enduring aerial bombardment from a Cabal warship.
During the event, a lone Cabal dropship will sporadically fly around the area, occasionally stopping to shoot at you and your fireteam. Destroy this small dropship to enable the heroic event (don’t fret if it flies away after you first exchange as it will return for a second pass). Once it’s destroyed, an Honored Colossus will spawn as the Heroic modifier.
The normal objective for this event is to kill Psions until the Infiltrator Valus enemy appears. In order begin the Heroic version of the mission, you and your fireteam will need to destroy the open heat vents on the top, middle and bottom levels of the Injection Rig as they open.
In this public event you’ll encounter a giant fallen servitor which will spawn smaller servitors to protect it with a shield.
Simply destroy all the small transport servitors before they disappear to activate the heroic mode – you’ll need to make clever use of your super when it spawns more than one at a time, depending on how many players are taking part in the event.
The Banish the Taken Blight event has you killing taken enemies until the Blight % reaches zero.
In order to trigger the Heroic version of the event, keep dipping in and then out of the Taken “domes” or “bubbles,” then attacking the large central Blight while you have the Blight Receding buff active. This is the only way to damage the central Blight, and you need to destroy it to trigger the Heroic modifier and eliminate the Blightmaker that appears.
This event on Titan normally has you trying to defeat a powerful Abyssal Wizard. To trigger the Heroic modifier, eliminate the two Ritual Witches as you normally would, then stand in the circle of runes (they glow green at the start of the event) and fire on the small crystals at the top corners of the portal until they’re destroyed.
Once the Heroic modifier has been triggered, you’ll need to defeat the Abyssal Champion to complete the event.
