Uldir – G’huun Guide

G’huun

Major gimmick of the fight that repeats many times Power Matrix/Reorigination Blast combo that is done on upper balcony part of big circular room.

There’s two paths that go to left and right from entrance on balcony, and a yellow orb will spawn on alternating sides, starting from left. The orb needs to be delivered to the end of the platform and inserted into titan device to trigger the Reorigination Blast. How it works is one player picks up the ball and runs like hell, the carrier will be slowed by 20% every 2 seconds until getting totally frozen after 10 seconds, and will need to throw the ball to next in chain to carry it further with extra action button.

Classes with very high mobility (warriors with charge, monks with teleports and DH’s) and warlock portals can actually solo it. Same player can not pick up the orb twice in a row (there’s 5 minute debuff) but it will not prevent catching the ball from somebody else or passing it along.

When ball is delivered Reorigination Blast does aoe damage to whole room, enemies and players, and will stun all enemies for 24 seconds and increase their damage taken by 100%. Raid needs to be stacked up and be spam healed with cooldowns. This needs to be done several times in the fight, as often as possible to increase damage done and stun the enemies. Major mythic mode difference is that two balls need to be delivered within 3 seconds of each other to trigger the Reorigination Blast. Stacking high mobility classes for this is pretty much required, especially for mythic mode.

In addition the balconies have adds that slow people along the way, but those are mostly nuisances and part of the difficulty of ball carrying.

Phase 1

Blood Shield makes boss heals 10% every second so touching it is pointless

Explosive Corruption is debuff on random player that puts five second timer after which it explodes. Player needs to run away from the group as far as possible to explode and leave behind nasty puddle which will shrink and vanish over time. Five green balls spawn from the explosion going outwards, and touching those or standing in the puddle will pass on the Explosive Corruption debuff so avoiding them is critical.

Three types of adds spawn during the phase. Adds are very similar to Il’gynoth’s add phases.

First priority is Blightspreader Tendril which is big tentacle sticking from the ground. These spam cast Decaying Eruption which is critical to interrupt, otherwise it does around 50% health damage to whole raid. At 0 energy they will burrow and move elsewhere in the room, repeating until killed. These tentacles are only in heroic mode.

Many Cyclopean Terror tentacles spam Torment (mind flay type channel) on random people. Interrupt as much as possible.

One Dark Young need to be tanked, preferably on top of some other adds for extra cleavage. They periodically cast big hit and knockback on tank so repositioning is needed. Every time Dark Young reaches 100 energy it does Dark Bargain which increse damage done, damage taken and healing done by all players and enemies within 10 yards for 30 seconds. Using this buff is probably necessary on heroic and mythic difficulty to kill off Blightspreader Tendrils in time. Big problem is that second stack of Dark Bargain will MC players hit by it, and they have to be killed. Tank swap and maybe 2 groups to get the buff should be arranged. Fatboss video said they left this add up on purpose to help kill other adds, but it’s risky and we probably shouldn’t do that unless dps is a problem.

Phase 2 starts after three Reorigination Blasts are cast

Upper platform works exactly the same way as first phase, and can and should be used as much as possible to stun the enemies and increase their damage taken.

Corrupting Bite is tank debuff. It stacks damage taken by 15% and tanks need to swap at about 5 stacks.

Wave of Corruption hits everyone in the room doing 5 yard radius explosion, knockback and a stacking dot Putrid Blood. Raid needs to be spread out enough to avoid spreading explosions.

Blood Feast hits random player and immobilizes for 10 seconds. Afte rthe time is up Gibbering Horror add will spawn and eat all Putrid Blood stacks within 8 yards. For each Putrid Blood stack consumed the add will gain 5% health and damage done. The add just spams Mind-Numbing Chatter over and over again which interrupts casting for 3 seconds and does raidwide damage. Naturally it needs to die asap. Ideally Reorigination Blast should be timed so that it happens just after this add spawns to get rid of it easier.

Explosive Corruption from phase 1 continues unchanged.

Phase 3 – no video from this exists yet

At 15% health G’huun destroys the Reorigination Drive which causes rocks to fall and do fatal damage that can be reduced by distance.  Unsure where and how often the rocks fall.

Corrupting Bite, Wave of Corruption and Explosive Corruption continues from phase 2 unchanged, except there’s no way to drop stacks that come from the wave which creates soft enrage. In addition there are few new abilities in this burn phase.

Malignant Growth are stuff that pops up near players and explode in 8 yard radius. Raid needs to be somewhat spread out and quick to move from these.

Gaze of G’huun is similar as the gaze on Yogg-Saron. Turn away or be feared for 6 seconds.
