Ultraxion

Ultraxion is the fifth boss to appear in the Dragon Soul raid.[1] He is so monstrous that he cannot land atop Wyrmrest Temple, so players must stand on the ledge and battle him as he flies next to the temple. The damage in the fight is reminiscent of Patchwerk in Naxxramas with just ridiculous amounts of damage; a gear check boss. However, while Patchwerk was a simple tank and spank, Ultraxion has mechanics which can tax the coordination abilities of the raid.

World first heroic kill on 25-man achieved 7.12.2011 by Exodus - US-Ysondre.

Background[]

Adventure Guide[]

More an abomination of dark energy than a dragon, Ultraxion has spent his short life absorbing the essence of captured nether dragons. Ultraxion is the only twilight dragon Deathwing has praised, and his arrogance is overshadowed only by the crackling energies surging through his twisted form. Loyal to his master, Ultraxion swears to bring about the fall of Wyrmrest Temple.

Abilities[]

After 6 minutes have passed, Ultraxion will cast Twilight Eruption, a 5 second cast that will instantly wipe the raid.

  • Spell fire twilightimmolation Unstable Monstrosity — Growing Twilight instability causes arcs of Twilight energy to erupt from Ultraxion's hide, inflicting 300,000 Shadow damage every 6 seconds, split evenly among enemy players in the Twilight Realm and within 30 yards of the target. Every minute that Ultraxion remains in combat reduces the time between arcs by 1 second, to a maximum rate of one arc per second In addition, the instability prevents Ultraxion from parrying attacks. Raid Finder: 536250; Heroic Difficulty 10-player Heroic: 400,000; 25-player: 825,000; Heroic Difficulty 25-player Heroic: 1,100,000
  • Inv misc shadowegg Twilight Shift — At the beginning of the battle, Ultraxion pulls all enemies with him into the Twilight Realm, where they can bear the full brunt of his powerful Twilight assaults. Being pulled into the Twilight Realm grants players the Heroic Will ability.
    • Spell shadow mindtwisting Heroic Will Important — The player's Heroic Will steels the caster's mind to resist the forces of Twilight. This pulls the caster out of the Twilight realm for up to 5 sec, but renders them unable to attack, cast spells, or move while concentrating.
  • Ability druid twilightswrath Fading Light Important — Ultraxion sucks the light out of his current target and one random player, drawing them into Twilight over 5-10 seconds. Upon expiration, players in the Twilight Realm instantly dies. Players in the normal realm forcibly enter the Twilight Realm, and are afflicted with Faded into TwilightUltraxion sucks the light out of: Raid Finder – Current target; Heroic Difficulty 10-player Heroic – 2 random players; 25-player – 3 random players; Heroic Difficulty 25-player Heroic: 3 random players.
    • Spell magic lesserinvisibilty Faded into Twilight Important — Residual Twilight effects cause all threat against Ultraxion to be reset, In addition, no threat will be generated for 5 sec. In Heroic Difficulty, players take 100% more Physical damage for 5 sec, instead of generating no threat.
  • Spell shadow twilight Hour of Twilight (Heroic modeDeadly — The Hour of Twilight falls upon Ultraxion's foes. Enemies caught within the Twilight Realm take 300,000 (Raid Finder: 195,000) unresistable Shadow damage. Players within the normal realm forcibly enter the Twilight Realm. If Hour of Twilight does not hit a player, the Aspects take the full brunt of the attack. This disrupts the shield protecting the Aspects and heralds the end of all life on Azeroth. The Aspects take the full brunt of the attack if the Hour of Twilight hits fewer than: Heroic Difficulty 10-player Heroic – 2 players; 25-player – 3 players; Heroic Difficulty 25-player Heroic – 5 players. Aspects never take the full brunt in Raid Finder difficulty
    • Ability rogue envelopingshadows Looming Darkness Deadly Heroic Difficulty — When struck by Hour of Twilight, powerful waves of Twilight energy course through the victim, rendering them more susceptible to the harmful effects of Hour of Twilight. Players instantly die if Hour of Twilight inflicts additional damage to them.
  • Spell fire twilightflamebolt Twilight Burst — If every player stands outside the range of his powerful claws, Ultraxion expels a powerful burst of Twilight energy. This burst inflicts 75,000 unresistable Twilight damage on all players and increasing their magical damage taken by 50% for 6 sec. This effect stacks. Raid Finder: 48,750
  • Spell fire twilightcano Twilight Eruption — After 6 minutes have passed, Ultraxion's instability reaches uncontainable levels and erupts outwards as a massive explosion that destroys all nearby foes and Ultraxion himself. If the shield surrounding the Aspects should fall at any point during the encounter, Ultraxion will immediately trigger Twilight Eruption.
  • Protection of the Aspects — The aspects provide limited aid to the players as they fight Ultraxion.
    • Alexstrasza Healer Alert
      • Inv misc head dragon red Gift of Life Healer Alert — Alexstrasza creates a crystal of pure life energy.

Only one buff granted by Alexstrasza, Ysera, or Kalecgos can be present on a player at any time.
    • Ysera Healer Alert
      • Inv misc head dragon green Essence of Dreams Healer Alert — Ysera creates a crystal of dream energy. Activating the crystal imbues one healer with the power of dreams, which causes all healing done to be duplicated and distributed evenly amongst all friendly targets within 50 yards for the remainder of the battle. The crystal has one charge. Only one buff granted by Alexstrasza, Ysera, or Kalecgos can be present on a player at any time.
    • Kalecgos Healer Alert
      • Inv misc head dragon blue Source of Magic Healer Alert — Kalecgos creates a crystal of amplified arcane energy.

Strategy[]

Ultraxion is a DPS and healing race, requiring the group to handle a tank-swapping mechanic while doing high DPS to the boss and surviving constant AoE damage and the Hour of Twilight effect.

The fight takes place in the Twilight Realm, and players must be in the realm to do damage to Ultraxion. The Heroic Will ability, which appears on a big purple button in the center of the screen, allows players to escape the realm for several seconds. Using this ability properly is the key to surviving the fight.

All players need to be aware of the Hour of Twilight cast, which comes about once a minute (45 seconds on normal). One person (or three in 25-man) must remain in the twilight realm or the raid will instantly wipe; the other players must use their Heroic Will button to escape the twilight realm and avoid the damage.

Tanks[]

Tanks must use damage reduction cooldowns to survive the Hour of Twilight - note the Last Defender of Azeroth buff which doubles the power and halves the cooldowns of these abilities. Tanks must also manage the Fading Light debuff. The current tank will receive the Fading Light debuff at some point; when he is about to die, the offtank must taunt Ultraxion and the current tank must use Heroic Will to survive Fading Light. After the Heroic Will ends, that tank will generate no threat for 5 seconds; he must then watch the offtank until the next Fading Light, and taunt to pick Ultraxion back up.

DPS[]

DPS must watch for the Hour of Twilight effect, and be ready to use Heroic Will to survive it. DPS players can maximize their damage by saving the Heroic Will for the end of the Hour of Twilight cast bar. DPS should stack near the front of Ultraxion for AoE heals. If DPS receives the Fading Light debuff, they must use Heroic Will when they have just a few seconds left before the Fading Light effect triggers.

Healers[]

Healers need to heal the AoE damage from Unstable Monstrosity, which is split among the entire raid. The cast rate for this AoE gets faster every minute the fight goes on, starting at once per six seconds and peaking at one tick per second for the last minute before the enrage at six minutes. Throughout the fight, Alexstrasza, Ysera, and Kalecgos will provide assistance in the form of buffs for the healers, Each of these buffs can only be given to one healer at a time, so decide wisely who should get them. Normally the red buff is best used on Holy Priests (Renew, Prayer of Healing, HW:Sanc) and Druids (Wild Growth, Rejuv, Lifebloom), the green buff for Holy Paladins (Divine Light) and Shamans (Greater Healing Wave), and the blue buff for Shamans (Chain Heal spam), Disc Priests (Prayer of Healing spam) and Paladins (Holy Radiance spam), though depending on the healers different combinations might work just as well.

Fading Light details[]

Periodically throughout the fight Ultraxion will cast Fading Light on the tank and one (for 10-man, three for 25-man) other player(s). Each affected player will get a debuff with a timer between 5 and 9 seconds. If the player is still in the twilight realm when the buff expires they die. To avoid this use Heroic Will to exit the twilight realm when the buff has around 3 seconds remaining. Since Heroic Will only lasts 5 seconds if you use it too early you will return to the twilight realm in time to be killed by Fading Light. If you do not use it at all you will be killed by Fading Light.

If you have lag you are somewhat doomed.

Heroic Mode and surviving Hour of Twilight[]

For difficulty levels other than LFR, a certain number of players must remain in the twilight realm during Hour of Twilight (and be exposed to massive damage) to avoid a wipe.

LFR normal heroic
10-man 0 1 2
25-man 0 3 5

In 10-man normal the default tactic is to have the tanks take turns because Last Defender of Azeroth guarantees that every properly-specced tank has an appropriate 90-second survival cooldown. Optimizations are possible (such as a DK with Spell shadow antimagicshell [Anti-Magic Shell] eating all of the Hour of Twilight).

For 25-man or heroic this means that some non-tank players who can survive a 300,000 point hit must remain in the twilight realm and absorb the Hour of Twilight.

The major complicating factor in heroic mode is the Looming Darkness. A player who suffers Hour of Twilight during a heroic encounter is afflicted by Looming Darkness which lasts for 2 minutes. If a player with Looming Darkness suffers another Hour of Twilight they are instantly killed. This means that players in heroic mode can not absorb an Hour of Twilight more than once every 3 casts or they will die (which is still preferrable to wiping).

Building a successful cooldown rotation (and actually executing it) can be quite confusing if you don't have enough Spell shadow antimagicshell [Anti-Magic Shell]. Consult the following chart to help you choose a rotation:

Tank Cooldowns[]

Non-Tank Abilities[]

The following abilities can be used by non-tanks to survive Hour of Twilight casts.

Class Abilities Interval
Feral Combat Druid Ability druid tigersroar [Survival Instincts] 3 minutes
Paladin Spell holy divineshield [Divine Shield] 5 minutes
Shadow Priest Spell shadow dispersion [Dispersion] 2 minutes
Rogue Ability rogue feint [Feint] + 3/3 Ability rogue envelopingshadows [Enveloping Shadows]

10 seconds

2 minutes

Hunter Ability whirlwind [Deterrence] 2 minutes
Mage 2/2 Spell fire rune [Cauterize]

Spell frost frost [Ice Block]

60 seconds

5 minutes

Keep in mind that especially in 25m raids, external single-target and raid cooldowns can also be used to keep players alive, especially non-tanks that are required to soak. Effective single-target cooldowns are Spell holy painsupression [Pain Suppression], Spell holy guardianspirit [Guardian Spirit], and Spell holy sealofsacrifice [Hand of Sacrifice], while raid cooldowns that can allow players to survive include the T13 4-piece tank bonuses (Vampiric Brood and Shield Fortress), Spell holy powerwordbarrier [Divine Guardian], Ability warrior rallyingcry [Rallying Cry], Spell deathknight antimagiczone [Anti-Magic Zone], and Spell holy powerwordbarrier [Power Word: Barrier]. Depending on your raid composition, multiple cooldowns may need to be stacked to ensure every player's survival.

DPS death knights with Spell shadow antimagicshell [Anti-Magic Shell] and Spell deathknight iceboundfortitude [Icebound Fortitude], balance/restoration druids with Spell nature stoneclawtotem [Barkskin], holy/ret paladins with Inv glyph majorpaladin [Glyph of Divine Protection], enhancement shamans with Spell nature shamanrage [Shamanistic Rage], and destruction warlocks with Inv glyph majorwarlock [Glyph of Soul Link] and Spell shadow netherprotection [Nether Protection] are not necessarily able to eat an Hour of Twilight without assistance, but have excellent mitigation abilities and hence are excellent candidates for staying out with help from the above cooldowns.

The Heroic Will effect can be bound to the "Extra Action" keybinding. If you use an addon that changes your interface, this may prevent trouble with the button. An alternative to permanently assigning a key binding is to create a macro of

/click ExtraActionButton1

and load it onto your action bars for the fight.

Solo Strategy[]

Soloing Ultraxion is a challenging DPS race because you must kill Ultraxion before the first Hour of Twilight. Use all your DPS cooldowns immediately and kill the boss as quickly as possible.

To solo Ultraxion 25H at level 100, an item level of 650 or higher is recommended.

Speculation[]

Questionmark-medium
This article or section includes speculation, observations or opinions possibly supported by lore or by Blizzard officials. It should not be taken as representing official lore.

It is possible Ultraxion was originally meant to be Chromatus, possibly because animating a chimaera-like being turned out too hard for the developers. Chromatus just disappeared from the story, and Ultraxion drops a chromatic drake mount. It could also explain why the Twilight's Hammer was present in the Eye of Eternity, as Chromatus was originally imprisoned in an Arcane Prison, technology of the Blue dragonflight.

Patch changes[]

  • Cataclysm Hotfix (2012-02-07): The event leading to Ultraxion now requires 15 Drakes killed, down from 24.
  • Cataclysm Hotfix (2011-12-23): Fading Light should now always appear in raid frames when a player is affected by it.
  • Cataclysm Hotfix (2011-12-02):
    • The minimum heal required to activate Essence of Dreams is now 1500, up from 500.
    • Raise Ghoul, Spell deathknight bloodtap [Blood Tap], Inv sword 62 [Empower Rune Weapon], and Spell deathknight armyofthedead [Army of the Dead] no longer benefit from the cooldown reduction and the duration increase from the buff Last Defender of Azeroth.
  • Cataclysm Patch 4.3.0 (2011-11-29): Added.
