The Iron Dragon Unit 73, codenamed IDU-73, is the second boss encounter inside Uldris. This fight includes various Runes that can either empower the players, granting them enough strength to take down the mighty creature, or infuse the monstrosity with its ancient powers, causing the boss to wreck havoc among the raid in an unstoppable manner.
Background
Created by the Iron Dwarves of Uldris, this monstrosity is a fearsome sight to behold. Decorated with powerful runes along its body, the Iron Dragon, codenamed IDU-73, has been given its own artificial brain to function without supervision. This has proven to be a mistake as the Iron Dragon made quick work of its creators and now watches over the runes scattered about. Should the IDU-73 consume the power of all the runes, it will have enough power to wipe out armies upon armies with little to no effort.
Abilities
The IDU-73 goes berserk after 7 minutes of combat. All runes are inactive at first, but become active over time.

Uldris Storm Magus
Fighting the IDU-73 on Heroic difficulty causes 2/4 (10/25) Uldris Storm Magi to storm onto the terrace and attempt to deal with the players and the IDU-73. They will resort to attacking the IDU-73 over players unless they are struck first. Storm Magi will spawn every minute.
Uldris Storm Magus — These Iron Dwarfs storm onto the Terrace of Recreation to deal with the players and attempt to subdue the IDU-73. They are susceptible to most forms of crowd control.

Strategy
IDU-73
Have all players move in at the same time and stack up behind the boss. This fight becomes a healer's test as the boss begins to gain stacks of Shock Charge over the course of the fight through many attacks. This will cause all Nature damage-based attacks to hit harder as the fight progresses. The IDU-73 will slowly be able to kill the MT within the channel of Storm Breath. The OT should be on the boss' side so he/she should be ready to pick up the boss after each Wing Strike which will lower the current tank's total threat by 30%. However, the OT should be 2nd in threat as to prevent it from turning to the raid and thus using its Storm Breath on everyone.
Shortly into the fight, the IDU-73's rune abilities will come into play. It will cast either Rune of Incision or Rune of Empowerment. Incision will cause the boss to ignore 15% of the tank's armor with its melee attacks. Empowerment will increase the damage dealt by the boss by 30%. Empowerment is more deadly as it increases the damage of Storm Breath, which will make it capable of killing the tank when combined with many Shock Charge stacks. Protective cooldowns should be used when Empowerment is on the boss along with several Shock Charge stacks. However, as these Rune abilities are on the same 30 second-cooldown, they last 1 minute each so there is a possibility that both Runes will be on the boss at any given time, making healing the tank stressful.
Ancient Runes
One minute into the fight, a Rune of the Storms will activate for 15 seconds. Only 2/6 (10/25) players can click the rune at a time. This will grant those players a +100% damage boost for 1 minute. If two (or six for 25-man) of your best dps gain this buff, 
[Time Warp] or similar effects can be used to help burn the boss as much as possible during the minute-long duration. Unfortunately, players have to wait 90 seconds after using a Rune to be able to click on them again. If the boss moves too close (30 yards) to the rune, it will gain the Static Aura buff. This effectively starts the healer test as it deals 40k damage to the raid every 3 seconds. This lasts for the remainder of the fight. As the boss gains more stacks of Shock Charge, this aura will start hitting harder while putting more stress on the healers. Empowerment will just call for raid cooldowns to survive the damage.
One minute after the first Rune becomes active, the next rune called Rune of Titanic Fury becomes. Similar to the first rune, only a certain amount of players may gain this effect. This grants a buff increasing all haste by 100% for 1 minute. Healers should get priority for this buff to help counter the damage that continues to increase. Should the boss get within 30 yards of this Rune, it will gain a new ability called Thunder Beacon. It will cast on the tank which in turn causes extra damage to all players within 20 yards each time the affected tank gets hit by a direct damaging attack. This will call for a tank switch to prevent unwanted damage. However, Wing Strike may cause the boss to automatically switch to the debuffed tank which ends up causing more damage.
At the 3-minute mark, the Rune of Indomitable Power activates, reducing the spell and ability cooldowns of those who click it by 90% for 1 minute. Healers will benefit from this ability and tanks as well but they will be occupied with the boss. If they can, the tanks should drag the boss towards the rune beforehand and click on it when it becomes active. This will help them deal with the boss better by using their cooldowns each time they are ready. However, if the tanks are going to move the boss towards the Rune, they should take care the raid is away from the boss' front as to prevent Storm Breath from hitting the whole raid. Being within 30 yards of the rune causes the IDU-73 to gain an ability called Lightning Crash. This hits several raid members and stuns them for about 4 seconds. In addition, any direct damaging attack that hits those stunned will cause twice the damage. This ability can hit the tank but has a low chance of striking them. If it does, not much can be done about it other than taunting the boss to prevent unneeded damage.
All runes will deactivate for 2 minutes after being used and players must wait 90 seconds before using another rune so a rotation may be needed so that players (not necessarily the same ones) are always affected by a Rune buff.
