Once the ruler of K’aresh and sworn to defeat Dimensius, Nexus-King Salhadaaar reveals that he formed a pact with the very being that shattered his homeworld. Atop his Royal Voidwing, Salhadaar commands the Shadowguard to ensure the return of his master, Dimensius.
Nexus-King Salhadaar is the seventh boss encounter in the Manaforge Omega Raid.
This is a 3-phase encounter with two intermissions. Salhadaar will use both powers of the void and The Royal Voidwing during Phase One. During Phase Two, the images of the Voidwing converge back into one, and Salhadaar takes his seat atop The Royal Voidwing. The first intermission features Shadowguard reinforcements arriving to assist Salhadaar. Defeating Salhadaar's reinforcements will force his hand, where he consumes the remaining energy of The Royal Voidwing, greatly empowering him as a final stand against the Void Lord's return.

Prep:
Split the raid in two (try to get interrupts/stuns on each). BLOODLUST on Int. 2.
Phase 1 - Oath-breakers
Everyone starts with 3 stacks of debuff.
Remove all stacks before end of P1 or you will be mind controlled.
HEROIC: dying also mind controls you.
Raid stacks in two groups behind boss.
TANK: Vanquish and Conquer - taunt swap during each cast (it won't swap target)
Vanquish = cone, aim away from raid.
Conquer - soak. Alternate groups to soak.
Behead - targeted by large scratch marks - run out of raid to drop puddles.
Banishment (dot) - those players spread to avoid splash damage when it expires.
Avoid floating beams.
Phase 2 - 50% HP
4 Players targeted for portals to spawn. Big blue puddles. Move out and at least 30 yds apart.
Dimension Breath - beams from all portals plus one at the TANK. Tank aim beam away from raid. Raid avoid all beams.
HEROIC: Damage taken by the tank and any raiders hit by beams will explode raid wide at end - tank mitigation for breath (and everyone avoid getting hit!)
Intermission 1 (time)
Boss goes immune. Adds spawn on side platforms.
Split raid to deal with adds - use EAB to teleport there/back. Avoid beams.
Reapers - stun; Nexus-Prince - interrupt (prio), dodge rotating beams; Titan - swirlies (kill first).
Intermission 2 (adds die)
Dragon takes 100% more damage.
Boss absorbs Dragon's health.
BLOODLUST and nuke dragon.
Avoid beams.
Phase 3 (Dragon dies)
Galactic smash - 3 (6 on HEROIC) raiders targeted, spawning a dark star (cloudy puddle)
Targeted raiders spread equally near the edge to cancel out the "pull" from the stars. Everyone else in centre.
Avoid getting pulled into stars.
Dodge expanding rings.
Starkiller Swing - raiders targeted by missile (shows via line). Aim missile at a dark star. One each.
HEROIC: Dark Stars will be orbiting around the centre platform.
