I hope the last raid boss fight is going to be on Neptune in the Shadow of Saturn, the Darkness gathers and becomes stronger than ever, taking on a physical form like the traveler. Before the falling Debris Bridge appears however, there will be a mechanic where the darkness will choose three guardians at random to corrupt. Corrupted Guardians May inflict friendly fire upon non-corrupted Guardians and Vice Versa . Corrupt Gaudiness will also create an aura around themselves that Taints the light of Non-Corrupt Guardians and stops health regeneration for 15 seconds. Corrupt guardians can only take damage from Non-Corrupt Guardians, so the only way to advance is for the Non-corrupted guardians to kill their corrupted allies. Guardians will have to cross chasms of falling debris to reach the traveler(who has awoken and traveled to Neptune to assist the guardians) By reaching the Traveler, all dead allies will be revived immediately, and six relics will spawn throughout the arena. Guardians will have 45 seconds to reach each relic, which will provide them with an Aura that absorbs all incoming damage and transfers it to the darkness as damage, as well as providing a buff that allows guardians to do damage themselves to the darkness. The buff may stack, meaning that when guardians gather together, they may combine their auras in order to do more DPS. When the darkness reaches half health, it will begin teleporting guardians away from each other during DPS time as an effort to survive by limiting DPS. If the Darkness becomes enraged (12 minutes) it will begin to drain the traveler's light, and after 2 minutes the traveler will die and all guardians will wipe.
