Chromaggus

Chromaggus is a two-headed dragon beast creation of Nefarian, who acts as a dutiful protector of Blackwing Lair.World of Warcraft: Exploring Azeroth: The Eastern Kingdoms, pg. 44 Despite his canine appearance, he's actually a dragonkin (more specifically a drakeadon).
Chromaggus is a boss coming after Flamegor and before Nefarian. One of the most challenging aspects to Chromaggus is the randomness of his abilities. Chromaggus shimmers in a variety of colors, which relate to his current abilities. These abilities are determined upon instance creation, and will only be reset with the instance timer. He drops the Tier 2 shoulders for all classes.
==Cataclysm==
Chromaggus is now tameable and is categorized as a beast. When tamed, he is considered a core hound. Taming him can be dangerous because of his breath attacks, so use extreme caution. Like other core hounds, he requires the 31 point Exotic Beasts talent to tame.
==Abilities==
===Breath attacks===
Chromaggus' breaths are unique in that they do not only affect the front of Chromaggus, but hit everything within LoS of Chromaggus. In each new instance, Chromaggus will use two of five possible breaths. This combination will stay with him for the remainder of the instance timer.
* Incinerate : Red - 3675-4275 Fire damage. (This spell will hit for nearly 9000 Fire damage if you have the Black Affliction)
* Corrosive Acid : Green - Deals 875 to 1125 Nature damage every 3 sec for 15 seconds. Armour reduced by 3938 to 5062.
* Frost Burn : Blue - Attack speed reduced by 80%. Does approximately 1400 Frost damage.
* Ignite Flesh : Black - 657-843 Fire damage every three seconds for 60 seconds. This can stack if he casts it again within the 60 seconds the debuff lasts for.
* Time Lapse : Bronze - Stun for 6 seconds, reduces maximum health points to half. This ability used to permanently reduce threat, but does not do so as of patch 2.0.1. As with all stuns, Chromaggus will attack non-stunned characters first. When this debuff wears off, health points are raised again, effectively healing you.
A breath is cast every 30 seconds, and the 2 breaths alternate.
===Brood afflictions===
In addition to his two breaths, Chromaggus also radiates Brood Afflictions which debuff everyone in the zone, not just those in line of sight. They include:
* Brood Affliction: Red (Disease) - 50 Fire damage/3s. Heals Chromaggus on death.
* Brood Affliction: Green (Poison) - Healing reduced by 50%, 250 Nature damage every 5 seconds.
* Brood Affliction: Blue (Magic) - Movement slowed by 70%. Casting speed reduced by 50%. 50 mana and 1 health drained per second.
* Brood Affliction: Black (Curse) - Fire Damage increased by 100%.
* Brood Affliction: Bronze - 4 second stun at random intervals for 10 minutes. Can only be removed with Hourglass Sand.
It is extremely important that the raid is constantly cured of these debuffs as they not only hinder the players, but can result in a wipe if any player gets all five of the debuffs. This part of the fight is simplified by the Paladin's Cleanse; otherwise you will have to assign one or two of the various healer classes along with Mages and Warlocks' Felhunters to handle each type of debuff. Bronze affliction can only be removed with Hourglass Sand, which drops off the trash packs leading up to Chromaggus. (Mages can also activate Ice Block to cancel it). Only healers, tanks, and hunters should need to remove bronze affliction. All other classes can live with it and must adapt to the frequent stuns.
When a player gets all five afflictions, they will turn into an elite Drakonoid. This mutation cannot be dispelled. The only way to deal with this situation is by polymorphing or killing the mutant player. When the player dies, Chromaggus is healed for a significant amount of health, prolonging the encounter. Attempting to chain polymorph the player may become complicated by the immense magical resistance that the player gains from the debuff. As such, it is best to keep these debuffs from ever stacking past 3. It also helps to keep a Restorative Potion handy in case the main dispellers are running low on mana. Mages can use iceblock to remove afflictions, however they cannot ice block out of the mutation.
===Enrage and frenzy===
Chromaggus frenzies every ten to fifteen seconds throughout the fight and must be kept tranquilized by hunters. The frequency of these frenzies is much greater than those of Magmadar but not quite as often as Flamegor. Nevertheless, frenzy must be kept off or the tank will die very quickly.
At 20% health, Chromaggus will enter a hard Enrage that lasts the duration of the fight. He can still frenzy, which makes it even more important for hunters to stay on top of their tranquilizing shots. Additionally, healers who were taking time lapse breath should stop at this point and focus solely on keeping the tank up.
===Shimmer===
Chromaggus' skin can "shimmer", changing his vulnerability to a particular school of magic. If you have CTRA it will help you know when his vulnerability changes and identify it when it is found.
===Seasons of Mastery===
During the Season of Mastery, Chromaggus has the use of all five breath attacks. He uses them in a random order, and they are no longer affected by line of sight (with one exception; see below). In addition, cleansing the Brood Affliction debuffs will cause an additional effect:
*Cleansing Brood Affliction: Red drops a fire patch on the floor.
*Cleansing Brood Affliction: Green drops a poison cloud on the floor.
*Cleansing Brood Affliction: Bronze sets off a firework that stuns nearby players.
*Cleansing Brood Affliction: Blue spawns an ice block that can be used to break line of sight from Chromaggus's breath attacks. The ice blocks have a very short duration, so care must be taken with when the debuff is cleansed.
==Strategy==
The Chromaggus fight is all about line of sight.
There are several possible positions where he can be tanked effectively:
* The top of the circular ramp up to where Ebonroc and Flamegor patrol
* On the circular ramp itself facing down
* The door to his own room
* Between the cubbies on the right hand side before the circular ramp
Find somewhere that suits your raid and that you are happy with.
As described above, Chromaggus has different breaths. This fight is a long one, and the trick to it is to move OOS when CTRA gives a breath warning. All other than the MT should move OOS. Healing should intensify on the MT during this period as he will be taking heavy damage from whichever breath Chromaggus uses. The breaths are cast alternately so once you know which breaths he is using you can prepare appropriately.
During the fight Chromaggus will shimmer. This means his resistances have changed. He will become extremely vulnerable to one type of magic and extremely resistant to others allowing for a boost in DPS (or allowing DPS to slow for a time to allow tanks to keep ahead on aggro).
The one difference to this tactic is the Time Lapse breath. Commonly called 'hard mode' Chromaggus, Time Lapse is a breath attack that stuns. The stun is a binary spell which can be resisted with arcane resistance. Much like Onyxia when she does her fear attack, Chromaggus will target the person highest on his aggro list who is not stunned. 
In order to deal with Time Lapse the tactic in theory is simple, but in practice is harder. 
*Main Tank - Affected by every time lapse. After he recovers from the stun, Chromaggus returns to him.
*Off Tanks - Should build as high a level of hate as they can and then in turn run out of LoS on the Time Lapse warning. The offtank runs out of line of sight of Chromaggus (there should be a small contingent of healers who also avoid Time Lapse who can heal the offtank during these brief intervals) at every timelapse and are healed where they stand. When the MT's stun wears off, Chromaggus will loyally return and the fight continues as normal.
*Others - Should let themselves get hit by Time Lapse if they have more hate than the off-tank. Otherwise, they should avoid it.
A warlock can leave an imp on the ideal tank spot so that it is easy for the off tank and MT to get the positioning perfect.
For all who can decurse, it is important to be on the ball due to the Brood Affliction debuffs as described above. Especially on the main tank.
It is vital that hunters keep tranquilizing shot up on this boss as he causes three times as much damage when frenzied. The blue and bronze afflictions can prevent hunters from tranquilizing. That's a recipe for a dead tank and a wipe, so priests and paladins must place the highest priority on removing the blue affliction from hunters, and the hunters should each carry two Restorative Potions and five Hourglass Sands per attempt.
As this is a very long fight, it's not a good idea risking death to stay in the line of fire of a breath attack until the last moment. Get into a safe spot early. The breath attack is instant. Once you see the breath animation start, it's over. So, it's safe to move back into line-of-sight as soon as that appears.

==Notes and trivia==
*Chromaggus is a "memory" in the fight against Argent Confessor Paletress in the Trial of the Champion encounter of the Crusaders' Coliseum.
*As the name suggests (the word chromatic is derived from "khroma", the Greek word for "color", suggesting Chromaggus takes his powers from dragonflights from all colors)
*One of the realms in World of Warcraft is named after Chromaggus.
**See: Realm Names and their place in Warcraft Lore
*He appears as the third boss encounter in Blackwing Lair, the fourth wing of the Blackrock Mountain adventure in Hearthstone. Upon defeating all bosses in the wing, players are rewarded Chromaggus as a legendary card. His flavor text reads: "Left head and right head can never agree about what to eat for dinner, so they always end up just eating ramen again."
==Speculation==
Chromaggus is similar to a core hound, and it is possible that they are related, possibly by feeding or injecting dragon blood from various dragons from all dragonflights.. The Beast is a huge core hound found in the nearby Upper Blackrock Spire, captured by the black dragonflight (probably stolen from the Molten Core). Most likely The Beast is included in Nefarian's experiments with the chromatic dragonflight, which Chromaggus may be a result from. Interestingly, as core hounds (at least the ones found in Molten Core) are the servants of Ragnaros and therefore the enemies of Nefarian and his dragons (see Blackrock Mountain), Chromaggus may be an attempt by the black dragonflight to gain their enemies' strength.
