Ulduar 10m hardmode normal/heroic bug report

[NickZedd]

This is a bug report for all bosses in Ulduar 10, some on normal some on hc. The run was done on the 1st and finished on the 8th of July.

• I've separated the report into bugs first, and then tuning issues
• Issues that I'm unsure about are marked in italics. These should be double checked.
• I will edit the post if I find that anything is inaccurate.
• I will assume that you are going for pre-nerf frosthold tuning on heroic since it was mentioned by Radeghost and that seems to be how it's set up on the keepers and vezax atm.

General:

• boss1,2,3 units don't exist, no bossframes, etc
• no CD reset on some bosses: algalon, kologarn, iron council, hodir. Some of the others did reset CDs
• bosses give the wrong type of emblem
• logging into ulduar when it's set to heroic crashes your game if you don't have the patch.
• switching between heroic and normal crashes the game of anyone who doesn't have the patch.
• Weakauras that are set to load based on instance size do not work on heroic difficulty (Because it’s set to 0-man)

Trash:

• Rune etched sentry is stunnable
• Chamber overseer jump does no damage
• Chamber overseer orb does very low damage.
• Freya conservatory: All of the trash gets pulled when you pull the boss.
• Freya conservatory: Guardian Lasher is giving damage reduction buff to Nymph

Flame Leviathan normal hm:

• After a systems shutdown, the boss sometimes keeps chasing the same player he was chasing before even when they no longer have the Pursued debuff
• Boss randomly took two ticks of 9 MILLION damage from something, likely burning tar, but not sure. This killed the boss from 20% in 2 seconds on hardmode
• Pyrite that spawns after pulling boss has 0 health and just drops down immediately
• Pyrite moves very slowly

XT normal hm:

• void zones from the hardmode Dark Bomb spawn a Dark Fiend...
• Tympanic Tantrum channel happens instantly without being preceded by a cast (minor issue)
• Heart hitbox is HUGE, much larger than the boss itself.

Algalon normal:

• Heroic mode was not implemented at all for this boss. It was identical to normal mode.
• Collapsing Stars seem to move away from the center of the room instead of roaming around. They then get stuck at the edges of the room.
• after finishing his 7.5 second RP, algalon immediately attacks a nearby target instead of the one who pulled him.
• Boss does not reset when only one person is alive with Divine intervention on them.

Kologarn normal hm:

• Rubble adds don't seem to cast Stone Nova at all
• Right arm doesn’t absorb damage while gripping players.

Auriaya normal hm:

• Sentries don't seem to jump on anyone
• Guardians spam jump and interrupt non-stop

Hodir normal hm:

• beams either have a very small effect radius or just don't work very well, it's very difficult to get the beam buff
• AoE of icicles too big and destroys fire even without touching it. (1:54:27 in video)
• Icicle spawns seem delayed. They keep spawning where people were standing a couple of seconds earlier.

Thorim normal hm:

• the Jormungar in the pre-fight event sometimes faces a different direction and breathes on the raid before pull when you stand in the entrance, very annoying.
• the mobs behind the first mini-boss in the tunnel can be pulled through the door.
• Unbalancing strike was only used twice at the start of the fight and never again after that.
• Using divine intervention on one player in the arena lets that player tank everything while the rest of the raid does the gauntlet.

Freya normal hm:

• Small lashers don't seem to explode on death or only explode sometimes
• Every other unstable energy cast never happens. Combat log event happens but no beam.
• Players standing in unstable energy beams sometimes get the buff from elder brightleaf. It seems this was also happening sometimes on Frosthold (saw it towards the end of the Clarity realm first kill), but I can’t find any information about them adding that mechanic on purpose. https://www.wowhead.com/wotlk/spell=62243/unstable-sun-beam

Mimiron:

Heroic:

• Fight is impossible because Frost bomb despawns without doing anything. (heroic only)

Normal hardmode:

• Either Laser barrage hitbox is weird, or it sometimes bugs out and does no damage since you can walk in it.
• Aerial command unit resets threat between p3 and p4.
• Plasma Blast: on normal mode he seems to put it as a buff instead of a debuff, and there is no animation. Both debuff and animation work on heroic.
• Assault bot immune to stun
• Bomb Bots move very fast and don't have much of a pause upon spawning (not sure if this is intended)
• Rocket strike has no combat log event
• The rocket flying through the air from the rocket strike spell is invisible. The warning on the ground still appears but not the projectile itself.

Vezax heroic hm

• Vapors spawn very close to the walls and don't roam around very much.

Yogg heroic 1 light

• Squeeze debuff from constrictors stay on people permanently and kills you after the fight is over, even though immunities. (Should immunity protect you from squeeze dmg on pre-nerf?)
• Brain link debuff is only applied to one of the two players
• on pre-nerf, phase 3 should start when the brain reaches 0%, not when it reaches 30%.
• on pre-nerf, yogg should have reduced max hp, but start with 100% hp at the start of phase 3 (same amount of damage required to kill him, but his maximum hp should be lower)
• on pre-nerf, paladin judgements should not interrupt the crusher tentacle’s diminish power.

Razorscale:

• Boss got stuck in air permanently after being chained. Unkillable.
• Add spawns were inconsistent, sometimes spawns lots of adds sometimes just 2 packs.

TUNING ISSUES:

Freya

• p2 bombs do very low dmg
• Exploding lasher explosions do low dmg

Mimiron

• Assault bots do insane damage for normal mode. Makes sense that they would do at least this much on heroic though.
• Mine damage seems low even for normal mode. Also, make sure it one-shots on heroic.
• Frost bomb damage too low. It should one-shot.
• Heroic mode P2 aoe dmg is very low

Kologarn

• Boss hp low compared to arm hp, so killing arms is not worth.

Yogg

• brain dies too fast with just 1.3 mil hp. We 1-phased it which makes the outside part of the fight trivial since you never get overrun with tentacles.

Vezax heroic

• Animus raidwide aoe damage slightly too low to be threatening

[Godmatik]

Regarding the Freya lashers not exploding I remember the bug, happens if they are stunned before death.

Chamber overseer orb is not supposed to be attackable pretty sure

Never heard of brain having to reach 0% for Yogg, should just be 30% since it is tied to Yogg's actual health, nor ever heard about him starting at 100% health at start of p3. Pretty sure these are all custom Frosthold buffs.

[NickZedd]

It seems you're right about the orb on classic at least. Can't find anything from retail.

The yogg stuff is custom frosthold buffs that whitemane said they will add, yes.

[Godmatik]

So some Frosthold buffs they removing and some they keeping, or what will the deal be with heroic mode?

Would love some clarification here

"Collapsing Stars seem to move away from the center of the room instead of roaming around. They then get stuck at the edges of the room."

Confirmed about this - a very old bug They need to be fixed so they rotate properly around the room - right now they get stuck on the edges

So far I have only heard that they will apply frosthold buffs on heroic, so I'm assuming that means all, even on 10m. Some seem to be implemented atm, others are not.
