Nezarec
The final fight of the raid consists of combat against the reborn Nezarec. Now fed with both Light and Darkness by the fireteam, he is now able to leave his sarcophagus. Getting in close proximity of this will trigger him to shatter it, slam to the ground and begin the encounter.

To open up Nezarec to damage, the team must link two sequences of Light and Dark seeds on the left and right sides of the arena respectively. Starting close to where the team enters this area are the first two usable seeds, highlighted by an aura surrounding them. Shooting this while inside the area of effect will grant the same buff as in previous parts of the raid. Similarly, a faint trail of Light or Dark will emanate from the shot seed, pointing to another which has just spawned and must be shot to create the link. Once linked, another aura will appear around a completed seed and a Guardian must shoot this, obtain the buff, then travel to the next indicated seed to shoot it, so on and so forth.

While this is being performed, many enemies will spawn in the arena. Colossi, War Beasts, and Legionaries will appear in waves to tarry the team. Also, Nezarec themselves will not sit idle, performing attacks similar to Tormentors. They will periodically throw Abyssal Cleaves at targets close to them, or spawn a floating pool of Void energy that will cast many of the same Abyssal Cleaves as it travels around the arena. Once enough time has passed, Nezarec will begin casting Nezarec's Hatred, which spawns a Psionic Blast beneath Guardians, which will blast them upwards after a set period of time, dealing damage. This will continue until Nezarec's chest weak point is broken. Once broken, Nezarec will jump down from their perch and begin chasing the Guardian who broke their chest, performing further Tormentor-like attacks, such as the Void suppression divekick they are known for. The hunted Guardian will eventually lose the attention of Nezarec, them picking a new target and chasing them, but it can be regained by once more breaking their chest.

The timer for the fight that determines failure or success revolves around a spell Nezarec will begin casting, wherein they begin to exhibit a strong white glow. Once enough time has passed, Nezarec will unleash a pulse of Overwhelming Energy or Overwhelming Light, wiping the entire team if they are not sufficiently protected. Similar to the platforming section before Macrocosm, Guardians must create a refuge of Light or Darkness, matching the spell Nezarec will cast. To determine this spell type, the shoulder weak points of Nezarec must be broken. Once both are broken, Nezarec will display a Light or Darkness coloured tattoo across his body for a brief amount of time, matching the spell they will prepare. Shoot the matching seed while holding the opposite paracausal affinity, similar to the pre-Macrocosm relay platforming, to create a field that will grant a 14 second buff that protects against being killed by Nezarec's spell. Be careful not to shoot a seed that currently holds an aura field around it, as doing so will not create a refuge. Instead, it will provide the Field of Light or Flux of Darkness buff instead. The protection buff can be refreshed repeatedly by getting close to the seed once the refuge has been created, and the refuge will stay until Nezarec casts the spell.

Once a side has fully linked their seeds, large pulses of energy will go off from them in sequence, indicating success. Once both sides have been completed, Nezarec will shortly become vulnerable, indicated by a blast of light striking them. During this vulnerable phase, Nezarec will display some new attacks, such as the ability to perform a teleport into a slam, a slam that spawns large spinning Void projectiles across the ground, mixed in with their regular Void slashes. As they are not inactive during the damage phase, it is advised to locate the team on the final seed spot on either the Light or Darkness sides, as Nezarec will be unable to teleport behind the group, ensuring that sight won't be lost during the short damage phase.

As Nezarec becomes immune, they will prepare a slam attack which will suppress any Guardian caught in the vicinity. This is the fireteams cue to return to their initial starting positions, from whence the fight repeats itself.

If Nezarec's health is depleted enough to reach Final Stand, Nezarec will roar, displaying more Resonant energy coursing through their body, turning black. Now it remains a race to deplete Nezarec's health before they prepare another Overwhelming Energy blast that will annihilate the fireteam.
