In Destiny 2 there are certain ways for you to turn a regular public event into a heroic event which provides you with a better chance of rewards. When the public event begins you must do a series of activities to turn that event into a Heroic one. Below is a list of the public events and what you must do to start a heroic.
Here’s what you need to do for each public event:
During each glimmer extraction, there will be a small device on the ground which is able to be destroyed. Destroy 3 of these and heroic mode will activate. When looking for it look for a small circular device that is beaming up glimmer. It takes a lot of damage so you will need to focus on it to destroy it before the crews are killed.
Periodically the inside of the bubble will start causing burn damage because of the jets. During this time, ports will open on the rig which you can damage. There are 3 tiers you have to destroy to activate the heroic mode top, middle, and bottom. This one is pretty tough because you are taking damage and they have a lot of health. Try to find a vehicle to help with the damage.
Damage the large servitor until it spawns smaller servitors which put a shield on the boss. Kill these smaller servitors when they spawn, there will be a few waves of them and eventually, 3 will spawn which should trigger the heroic once all are dead. Make sure to kill them quickly because they can disappear.
Disrupt Vex Construction
There will be 3 rings on the ground near the objective you have to defend, you can usually follow the light trails coming from the defense point. Stand in them until they reach 100% for all 3 to activate the heroic mode.
Each time you destroy one of the Devil Walker’s legs it will drop a bunch of orbs. These orbs are used to unlock the 3 cannons, once all 3 are unlocked it will switch to heroic and spawn a second devil walker.
Occasionally a ship will fly near the objective to give support to the waves of enemies. Destroy this ship to activate Heroic.
After you defeat the first 2 witches, there will be 2 shielded stones on both sides of the portal. Stand on the plates again to remove the shields and destroy the stones to activate Heroic.
There will be a big shielded blight with several smaller bubbles around it. When you step in and out of the smaller bubbles you gain a temporary buff that allows you to damage the central blight. When you do enough damage, heroic will be activated and a yellow mob will spawn.
If any are missing or you feel they don’t describe the process in enough detail be sure to comment below. On Wednesday be on the lookout for how to unlock several exotics in Destiny 2.
