I hardly know anything about Destiny lore. I know everyone wants a piece of The Traveler and that's about it. :) But going through strikes recently and trying to get Oxygen and the Service Revolver I noticed that many, many strike bosses (The Darkness?) have the ability to go immune. So far I haven't seen anything like that being given by the light. Yes, Guardians can get an overshield for a short period of time. And Titan bubbles also provide protection for short time. Exotics like One Eyed Mask and Wormhusk Crown can give health regen. But so far I can't find anywhere that the light can give full immunity to damage. Yet the darkness can provide immunity for some reason. In Destiny 1 I can't remember strike bosses having the ability to go immune, but maybe I missed something? I don't know if 'The Light' and 'The Darkness' are old fashioned terms, but I hope you guys know what I mean: Guardians who have light can't go immune. Enemy aliens/bosses who don't have light can go immune. So long story short: What can give these aliens the ability to go immune? Thanks for any help! :)
