Uldir – Zul, Reborn Guide

Zul, Reborn

Phase 1 – 100-40%

Pool of Darkness spawns in the room periodically. These last 20 seconds and do heavy damage to soaker every 2 seconds, requiring dedicated healer. Raid needs to be loosely spread, and whichever ranged is closest will soak these. Pools will not happen in lfr/normal difficulties.

Dark Revelation is debuff cast on one random person (2 in heroic/mythic) which explodes after 10 seconds dealing half of healthbar damage point blank and decreasing the further away you are (kinda like the soulburst on Argus). On explosion creates a bunch of Minion of Zul adds that fixate on random players and needs to be nuked down. Offensive dispell (including mass dispell) will kill these adds instantly. Having 2 priests with Mass Dispell ready will make this significantly easier to handle and almost mandatory. Probably will be mandatory in mythic mode. Blood Elf racial ability Arcane Torrent will also work.

Call of Blood spawns adds frequently.

• Nazmani Crushers do front cone attack and buff all nearby allies at full energy, so they need to be tanked away from other adds including the boss when close to full energy to prevent buffs.
• Nazmani Bloodhexers spawn blood blob adds that move towards boss to heal it, need to be nuked. Also spam interruptible Bloodshard on lowest health raid member that deals about 1/3 of full healthbar damage. Two bloodhexers buff each other which causes aoe pulse to whole raid.  Group with two bloodhexers needs either constant CC on one (preferred) or third tank (the lazy way) to keep them away from each other and the boss.
• Bloodthirsty Crawgs heal 200% of damage they cause, so CC/kiting necessary. They also explode timed (at full energy) putting fatal dot on whole raid.
• One tank handles boss and the crawgs in the middle of the room and other picks up crusher and bloodhexer far from boss. Kill order is bloodhexer>crusher>and just passive cleave/multidot the crawgs, making sure those die before reaching full energy. Adds spawn in semi-random  locations (few possible spots) during the fight, and in differenr sized groups.

Phase 2 – 40-0%

Phase 2 starts with Locus of Corruption which puts dot on whole raid. DOT strength depends on number of Corrupted Blood stacks, and number of Corrupted Blood stacks at the start of P2 depends on how long P1 lasted. Everybody gets knocked back at the start of phase so be in the middle-ish of the room.

Pool of Darkness from P1 continues.

Tanks get Rupturing Blood debuff that upon expiring gives additional stack of Corrupted Blood. Also periodically creates blood puddles around tank that gives Corrupted Blood for melee/tanks, requiring relocation of the boss. This acts as a soft enrage mechanic covering the whole platform in bad shit. Tanks need to run these somewhere behind where they are standing while leaving clear path for the rest of the raid to handle Deathwish.

Deathwish makes random player (two in heroic?) MCd and they will start walking towards edge of platform and jump off. Dispelling this does proximity based shadow damage to whole raid and spawns Minion of Zul adds like Dark Revelation in p1. Having two explode at the same time will need healing cooldowns, therefore it’s recommended to lifegrip one and dispel other to stagger the explosions. Because players start walking towards nearest edge and boss does cleave raid needs to position so that whoever gets MCd will not walk through boss and not walk through the big pools tanks spawn. Staggering might not be needed on  normal/heroic difficulty.

• P1 just loose spread near middle while being in range to kill adds. Closest people soak pools and two debuffs run out to opposite directions and as far as possible, (with priests assigned to mass dispel).
• P2 raid neatly stacked near the middle of platform, behind boss while making sure closest edge for the Deathwish does not go through boss cleave or any bad patches left by tanks. Will have marked player as stacking point.
