Ultraxion Encounter Guide: Strategy, Abilities, Loot

• Use your Heroic Will as late as possible, as both Hour of Twilight and Fading Light will instantly return you to the Twilight Realm when they finish.
• Ultraxion can not parry attacks.
• If you are not soaking Hour of Twilight, save you defensive cooldowns for as late into the fight as possible.

• DPS Ultraxion as much as possible; there is very little healing in the first few minutes of the encounter. Set up a priority for which healers are focusing more on DPSing, and which will stop DPSing in order to heal when needed. Later on into the fight all healers will be healing, so get as much extra damage in as possible in order to beat the enrage timer. Do not bring more than 5 healers.
• Use Heroic Will at the beginning of the encounter, right before Bloodlust is being used. This will allow the healers to avoid the Bloodlust (and the Sated debuff), allowing the healers to get a second lust at around 5 minutes into the fight, when healing required is extremely high.
• Save all raid-wide defensive cooldowns for after 5 minutes into the fight. You need to have 1-2 defensives up at all times for the last minute of the encounter.

• Instantly use all of your defensive cooldowns on the pull. When you gain Last Defender of Azeroth, your cooldowns will be reset.
• Last Defender of Azeroth doubles the duration of your defensive cooldowns, and makes them available 50% more often; use them a bit more freely on this encounter, as needed.
• The off-tank should be ready to taunt as soon as Fading Light goes out on the current tank.

Ultraxion is a 1-Phase boss that is a heavy DPS race. While the mechanics in this fight are rather easy to handle, they must be handled correctly every single time; incorrectly dealing with any of the mechanics on this fight can immediately lead to a wipe, or cause one down the road when the DPS check is not met. Ultraxion exists inside the "Twilight Realm", and will pull all players into said realm with Twilight Shift at the start of the encounter.

For this encounter, all players will gain the Heroic Will "special action button". Heroic Will has a 5 second cooldown, costs no resources, is not on the global cooldown, and can be used while casting. Using Heroic Will will temporarily remove the player out of the Twilight Realm for 5 seconds; we will cover Heroic Will and how it should be used later on in this guide. Heroic Will can be key-bound under the Keybindings Menu > Action Bars > "ExtraActionButton1", can be use through a macro /click ExtraActionButton1, or the button can simply be clicked.

Positioning for Ultraxion is extremely easy, simply have the raid stack up together for AoE healing. There is no movement required at all on this fight, so the entire raid can stay in this position for the rest of the encounter. Ultraxion will assault the raid with Unstable Monstrosity, dealing damage 1,100,000 damage, split evenly between all targets hit. At the start of the encounter, Ultraxion will cast Unstable Monstrosity every 6 seconds; however, for every 1-minute that Ultraxion is in combat, he will reduce this timer by 1 second. For example: after 1 minute into the encounter Unstable Monstrosity will be used every 5 seconds, after 2 minutes Unstable Monstrosity will be used every 4 seconds. This process of increasing the frequency of Unstable Monstrositys use will continue on (every 3 seconds after 3 minutes, every 2 seconds after 4 minutes, every 1 second after 5 minutes) until 6 minutes into combat. After 6 minutes in combat, Ultraxion will hard-enrage and cast Twilight Eruption, instantly wiping the raid. If no player is in melee range of Ultraxion he will cast Twilight Burst, dealing damage to the entire raid and increasing their magic damage taken every second, making this essentially a wipe.

Every 45 seconds Ultraxion will use Hour of Twilight, dealing 300,000 unresistable Shadow damage to all players still in the Twilight Realm at the end of the cast. This is where the special action button Heroic Will comes into play, as players can use it to temporarily exit the Twilight Realm and avoid the Hour of Twilight cast entirely. While we do want to avoid the Hour of Twilight damage, the ability must hit a certain amount of players depending on the difficulty of the raid (1 player on 10-Normal and 3 players on 25-Normal; 2 players on 10-Heroic and 5 players on 25-Heroic). If Hour of Twilight does not hit at least that many players, the nearby Dragon Aspects will be killed, resulting in a wipe.

As Hour of Twilights damage is unresistable and deals 300,000 Shadow damage, the only way to soak this and survive is through a powerful defensive cooldown. Set up groups of players to rotate between soaking, for example: 3 groups of 3 players with defensive cooldowns for 25-Normal, or 3 groups of 5 for 25-Heroic. Simply have these groups use a defensive cooldown while they are soaking the Hour of Twilight, then rotate to the next group who should have their defensive cooldowns available for the next Hour of Twilight. On heroic difficulty players that soak Hour of Twilight will be debuffed by Looming Darkness, which lasts for 2-minutes and instantly kills you if you soak another Hour of Twilight. With Hour of Twilight only occurring every 45 seconds, rotating between 3 groups of 5 players will allow you to avoid this all together.

The second ability that players must use Heroic Will to avoid is Fading Light, which will be used twice every 45 seconds, between each Hour of Twilight. Fading Light will always hit the current tank, and a number of random DPS depending on the difficulty (1 DPS on 10-Normal and 3 DPS on 25-Normal; 2 DPS on 10-Heroic and 6 DPS on 25-Heroic). The duration of the Fading Light debuff is random between 5-10 seconds, so players will need to be personally responsible for watching their own debuffs and using Heroic Will at the end of the Fading Light debuff. When the Fading Light debuff expires, afflicted players will die if still in the Twilight Realm, and players not in the Twilight Realm will be instantly returned to it. Upon returning to the Twilight Realm, players will be unable to generate threat for 10 seconds; this has no real impact on the fight as long as the off-tank taunts Ultraxion before the current tank uses Heroic Will.

Behind the raid stands the five Aspects of Azeroth, represented by: Thrall, Alexstrasza, Ysera, Kalecgos, and Nozdormu; these Aspects are the real target of Ultraxion, who is attempting to kill them every time he casts Hour of Twilight if enough players do not soak the damage. These Aspects will provide the raid with unique buffs, mostly focused on improving the healers capabilities; these buffs are required to make the fight even possible rather than simplifying it. Thrall will buff your tanks with Last Defender of Azeroth shortly after combat begins, greatly improving the functionality of their defensive cooldowns. Nozdormu will buff the entire raid with Timeloop 5-minutes into the fight; this acts as a cheat death, similar to Guardian Spirit. When a player with this buff receives lethal damage, the Timeloop buff will be consumed instead, and the player will return to full health. This buff can not be obtained a second time, meaning that every one only gets a single use of Timeloop, so make it count! The last 3 buffs provided by Alexstrasza, Ysera, and Kalecgos are all healer-specifc, and will be discussed next.

Unlike the previous 2 buffs ( Last Defender of Azeroth and Timeloop, the buffs provided for the healers are not automatically gained and must be "picked up" manually. Healers can only have one of these three buffs active at once, meaning the healers will need to pick the buff that is best for their class/spec and stick with it. At one minute and 30 seconds into the fight, Alexstrasza will drop 1 "Red Crystal" (2 on 25-man); these Red Crystals can be clicked by healers only to gain the buff Gift of Life, increasing all healing done by 100%. At two minutes and 30 seconds Ysera will create the same amount of "Green Crystals", which healers can click to gain Source of Magic, which will essentially "duplicate" your healing spell to be an AoE spell on the entire raid. Finally, Kalecgos will drop his "Blue Crystals" at the three minute and 30 second timer, allowing healers to gain the Source of Magic buff, which greatly reduces mana costs and increases spell haste. These buffs are very limited (1 each on 10-man and 2 of each on 25-man), meaning you will want to utilize them as best you can. We recommend the following for healer buffs, as this setup takes best advantage of each specializations specific toolkit:

• Gift of Life
1. Restoration
2. Discipline
• Essence of Dreams
1. Restoration
2. Holy
• Source of Magic
1. Holy

That's all there is to know about the Ultraxion encounter; it is a very mechanically simply fight intentionally, as it is meant to be a DPS check fight. You will need to bring as few healers as possible to beat the enrage timer, with 5 healers being the recommended amount. Healers will need to provide as much damage as they possibly can, especially at the start of the encounter, as there is very little to heal early on. You will want to use Bloodlust within a few seconds of Ultraxion being attack-able to get the greatest up-time possible. All healers should be sure to use Heroic Will before the Bloodlust goes out, as this will prevent them from gaining the Sated debuff and allows them to get their own Bloodlust around the five minute timer, when healing requirements are at the highest. Healers should also aim to be almost entirely focusing on DPSing Ultraxion early on, only casting 1-2 heals as needed before returning to DPSing. Discipline is great for this encounter due to Atonement allowing them to basically DPS for most of the fight, until raid-wide damage starts to become overwhelming. Overall, this is a tightly-tuned fight, where a single error will likely turn into a wipe, and DPS is king above all else.
