Greetings!

With Ulduar raid testing resuming very shortly we wanted to again give an update on recent bug fixes and adjustments in 3.4.1 and the Ulduar raid.

Resolved an issue causing the Hunter ability Kill Shot to crash the client for the hunter and other nearby players.

Developer’s Note: This was temporarily resolved early in the last testing period by disabling the animation related to this spell, but we’ve committed the “full fix” for this now and re-enabled the Kill Shot animation.

Fixed an issue causing Kill Shot and Volley to not gain appropriate bonus attack power from Hunter’s Mark.

Fixed an issue that caused Oil of Immolation and Troll’s Blood Elixirs to cause the player’s potions to become “permanently” on cooldown.

Stormjewel gems are not correctly unique-equipped.

Ulduar Raid-Specific Fixes and Adjustments

Ulduar General

Fixed an issue that allowed you to gain the Keeper of Ulduar buffs from Hodir, Freya, Thorim, and Mimiron outside of the Yogg-Saron encounter.

The RX-214 Repair-o-matic stations should now properly repair vehicles.

Fixed an issue preventing players from swapping to 10-player mode of the raid leader had an active 25-player raid ID lock.

Flame Leviathan

Fixed an issue causing Flame Leviathan to take too long to spawn after the final Ulduar Colossus is killed.

XT-002 Deconstructor

The Health of XT-002 Deconstructor has been reduced on Hard Mode in both 10 and 25-player versions.

Developer’s Notes: The version of the fight we had present on PTR was the very first version of XT-002 Deconstructor that was live for a very short time in 2009. This version was never defeated, and with good reason; it had an unfeasibly large health pool and players couldn’t hope to beat the enrage even with perfect gear and play at that time. We considered a lot of changes and ultimately decided to reduce the overall health to make it more in-line with this boss’s place within Ulduar as the 2nd required boss. The real-prenerf version of this boss will continue to be relegated to legend, just like a certain Old God residing in his winter vacation home in southern Kalimdor was.

Fixed an issue causing XT-002 Deconstructor to not case Searing Light and Gravity bomb in 10-player mode.

Resolved an issue causing the 25-player version of Heartbreak to apply to the 10-player version of the boss when the hard mode is engaged.

Razorscale

Reduced the berserk timer from 600 seconds to 360 seconds.

Dark Rune watchers have had their abilities correctly restored to pre-nerf levels:

Chain Lightning may be cast while the Dark Rune Watcher is moving.

Chain Lightning’s range is now 100 yards (up from 30).

Chain Lightning’s damage has been increased in both 10-player and 25-player modes.

Ignis the Furnace Master

Health increased in 10-player and 25-player modes by 20%.

Scorch Ground damage doubled in both 10-player and 25-player modes.

Molten Periodic Damage increased.

Strength of the Creator buff has been increased from 15% to 20% per stack.

Kologarn

Stone Grip now deals 4000 damage per second on 10-player and 5000 damage per second on 25-player.

Eye Beams now move slightly faster.

Thorim

Unbalancing strike default recast time reduced from 20 seconds to 15 seconds.

Unbalancing strike is no longer an “on next hit” style attack and is now correctly an instant melee attack.

Fixed an issue where the Dark Rune Warbringers would not properly clean up when the encounter ends.

Mimiron

Fixed an issue that caused Mimiron to immediately engage players on hard mode, before his RP had reached the appropriate point.

The Magnetic Core is now flagged to always be free-for-all lootable.

The Aerial Command unit should no longer spin at ludicrous speed during phase 4.

General Vezax

The Faceless Horrors leading up to Vezax should no longer be skippable.

Yogg-Saron

Guardian of Yogg Saron’s health has been increased on both 10-player and 25-player modes.
