[Spoiler]Datto: How to Activate Heroic Public Events

Very useful info with the minimum amount of spoilers.

Destiny 2: How to Activate Heroic Public Events

0:43 - Fallen Glimmer Event (You must destroy all 3 glimmer nodes. If you're shooting a node and it's showing damage numbers, that's probably it.)

1:34 - Fallen Ether Event (You must destroy all small Servitors that assist the big one.)

2:03 - Spider Tank Event on Titan (You must disable all 3 forcefields by using 6 arc charges, 2 per forcefield.)

2:44 - Witches Ritual Event (You must destroy the 2 shielded crystals by standing on the Hex Circles.)

3:25 - Vex Construction Event (You must activate all 3 Vex plates by standing in them until 100%.)

4:02 - Cabal Extraction (You must destroy the Cabal Thresher ship that patrols the area.)

4:38 - Taken Event (As event spawns, there is one main blight which spawns smaller dome blights to its side. If you step in and out of the smaller blights, you receive a buff blight receding. This allows you to damage main blight, which would otherwise be immune. Deal enough damage to main blight to spawn a new boss "Blightmaker".)

Thanks to u/ShadowRock9 here you have the taken guide with video

And finally thanks again u/ShadowRock9 :

Cabal Injection Rig (After killing each Psion, vents will expose themselves on the outer surface of the rig. Shoot and destroy it. 3 sets of vents and Heroic difficulty will trigger after the 3rd set is destroyed. All that remains is to kill an elite with increased damage resistance.)

Thanks Datto!!!
