One of the two dragons you fight for a boss encounter in the Bastion of Twilight. One dragon will be fighting on the ground, while the other stays in the air, and the two shift positions periodically, the airborne one casting a deadly, potentially raid wiping ability before landing.

While she's on the ground, she casts Blackout on random targets, a spell that absorbs healing, but explodes for massive damage split among all nearby targets when it's removed, along with a massive channeled flame breath (Hits in a 180 degree radius in front of her) that's aimed in the direction of a random raid member.

While she's in the air, she marks random players to be hit with Twilight Meteorites which split their damage among nearby targets, and does an Onyxia styled Deep Breath attack across the left, right, or center of the room multiple times before she lands.

Grim Batol was merely a setback.

How to: Valiona and Theralion (Normal)

First things first, start by pulling Valiona, as you want him(her?) on the ground much rather than Theralion.

Fight consists of one dragon being on the ground, while the other one spams stuff from the air. The bosses share a healthpool.

TL;DR version:
Valiona on ground: Spread, clump up on Blackout, spread again, avoid breath
Theralion on ground: Stack, debuffed player gtfo, move from void zones

While Valiona is on the ground, the basic idea is to stay spread out at all times to minimize meteor damage and clump up when Blackout hits someone. In 10man, have everyone get to melee when someone gets hit by blackout and in 25man, you can have separate ranged & melee groups if you dont want to run around too much. Just make sure you dispel Blackout fast when people are together to avoid useless meteor damage.
Also, when breath comes, either move behind the boss OR if thats not possible, move as far away as possible from the breath, it does pathetic damage at max range.
When Theralion is about to land, some swirling looking void zone thingies spawn on the ground, just dont get hit by them and dps Valiona as long as possible.

While Theralion is on ground, its the opposite. You gotta stack up to split the meteor damage equally between everyone hit, but you must keep some players at range at all times. The easiest way to do this is to have around half of your raid in melee stacked up and the rest spread rather close to melee. When one of the people at range get marked to be hit by next meteor, simply run to melee (You have 6 seconds to react and move) and back out after meteor.
As for other abilities, if you get Engulfing Magic, if you have anyone next to you, do not cast anything (If you have dots/hots in, move even faster), as all damage and healing done will be hit as aoe around you.
If boss turns head towards you, you can preemptively move away from the void zone that will come to the ground.
When Valiona is about to land, he does a breath which will cover a third of the room (Think Felmyst). Its not a huge aoe really, so its easy to dodge, as long as you move to the correct side.

After that, rinse and repeat. The phases rotate until bosses die. Spread on Valiona, stack on Theralion.

Strategy Guide:

Below, I have written a guide on the abilities and how we defeated this boss.

Our Group:

Tanks - | Druid |
Healers - | Shaman | Paladin | Priest |
DPS - | Death Knight | Hunter | Rogue | Paladin | SPriest | Mage |

General Boss Information:

This boss encounter involves 2 dragons, Valiona & Theralion.
Only one will be engaged at a time. The other one will be in the air harassing the raid until they switch.
They each do unique abilities and have pretty much the opposite mechanics. (Described below)

Boss Abilities:

Valiona: (On the ground)
While on the ground, Valiona will periodically cast Devouring Flames.
During this time, Theralion is in the air and while he is there, he will periodically cast Blackout on a random player and when dispelled, will deal ~300,000 split amongst players within 6-8 yards.
He will also cast Twilight Blast on a random raid member and splashes to other players within 6-8 yards, including melee.
Right before the phase change, Theralion will cast Dazzling Destruction which is indicated by gigantic galaxy looking swirls on the ground. If you get hit by these you get sent into the Twilight Realm.

Theralion: (On the ground)
While on the ground, Theralion will cast Engulfing Magic on a random raid member which increases damage and healing done by 100%, but also deals that damage or healing to nearby allies.
During this time, Valiona is in the air and will constantly be casting Twilight Meteorite on a random raid member, indicated by a big arrow above their head. It splits its damage amongst nearby allies.
The last thing Valiona will do right before the phase change is cast Deep Breath which deals ~15k damage and sends the player into the Twilight Realm. She will cast this in one of 3 rows in the room and is predictable.

Our Strategy:

Engage Valiona first and have everyone spread out as much as possible due to Twilight Blast.
When someone gets Blackout cast on them everyone needs to converge to split the damage it doeas.
Rinse and repeat these until Dazzling Destruction is cast. 6 of these will be cast and after they are done Theralion will land and Valiona will fly away.
At this time, everyone needs to stack. Melee on the tanks and Ranged on a designated player. This is due to Twilight Meteorite. In order to keep you moving, Theralion will place void zones on random players, so you will have to rotate around the outside of him as a group.
When someone gets Engulfing Magic is cast on a member, just have that person move out for the duration, then back in. If that person is targeted by a Meteorite, then have that person stop casting and stack.
At the end of this phase, Valiona will cast Deep Breath. It will engulf 1/3 of the room and will phase anyone hit by it into the Twilight Realm. It is very easy to predict this and just move out of it when it happens. The zones are selected at random.
Overall this is a pretty easy fight.

I wish you the best of luck, and feel free to critique my post and ask any questions.

As far as I'm aware, Valiona will not cast a Twilight Meteorite on a player with Engulfing Magic. That would be unbelievably painful.

But Valiona can cast a Blackout on a player with Engulfing Magic during the transition. To address this just wait for the Engulfing Magic to end and then stack up. Blackout lasts a pretty forgiving duration (15 seconds if I recall correctly), so you can allow the debuff to remain until the dispel is appropriate.

There are no specific pages for bosses, so I'm gonna throw this guide here for now.

Valiona and Theralion - This fight is an alternating two phase encounter. The fight will start off with Valiona on the ground, and Theralion in the air. Every once and a while, one dragon will fly up in the air, and the other one will come down. Only one dragon is active at any time, so don't worry about that.

A few seconds into the fight, Valiona will cast "Blackout" on a random raid member. Blackout will absorb 20k heals on it's target, and when removed or when the duration expires, the target will explode for 250k damage, split between the number of targets it hits. This means, that when someone gets Blackout, you need to stack on that person and either remove it when you know you're safe, or just wait 5 seconds for it to expire.

Every once and a while, Valiona will cast "Devouring Flame". This is a 2-3 second cast, and when she uses it, she will turn towards where she will breathe. Anybody standing infront of her while she is casting will take 25k damage a second. Needless to say, don't be infront of her when she uses this.

When Valiona is about to enter her air phase, she will start casting "Dazzling Destruction". This will cause several void zones to appear on the ground that appear in pairs. Standing in these void zones will cause 15k damage and send the target to the Twilight Realm. (If you are sent to the Twilight Realm, avoid balls and make your way to the portal.) After she is done, Valiona will enter her air phase and Theralion will come down.

Periodically, Theralion will cast "Twilight Meteorite" on a random person. The targeted player will get a purple arrow over their head, and the raid will need to stack ontop of them to split the damage. Theralion will also cast "Engulfing Magic". Any healing or damage taken by the target will mirror back onto nearby raid members. So if you get the debuff, run out of the raid.

Theralions last and most important ability is "Fabulous Flames/Dying Breath". This will leave a fairly large void zone on a random raider that takes a while to despawn. Because of this, you'll want to have your range stack up far away from the melee group and move west/left or east/right whenever a new void zone appears.

When this is over, Valiona will come back down and the fight just repeats until you kill her. Good luck! :-)

Grounding totem is currently stopping blackout making one of the more difficult mechanics completely irrellevant.

Having a shaman in each group is pretty much gg. On 10 man at least.

Comment by 259313

I didn't see it mentioned anywhere, but it should be noted that Dazzling Destruction and Deep Breath will cause an absurd amount of damage (Upwards of 500K) if they hit someone who's already in the Twilight Realm.

Comment by distortedshadow

Hey guys. After our raid had many frustrations with the 10-man version, we decided to switch our strategy from those shown in above comments and videos. Our strategy was way more efficient and effective for our group.

Raid Makeup:

: Paladin
: Mage, Mage, Warlock, Priest, Warrior, Warrior
: Druid, Holy Priest, Shaman

Our Strategy:

For Valiona, we did nothing unusual. If a mage got the magic debuff they ice blocked out of it, if anyone else got it we stacked on the tank, dispelled, spread back out.

When Theralion was on the ground however, we had everyone except for the 2 mages and the warlock go into MELEE. Much like Magmaw, certain mechanics are simpler if you reduce the amount of people in ranged. This way, most of the time people were already stacked in melee for meteor. If a ranged person got meteor, they simply moved into melee.

Void zones heavily prefer a ranged target, rarely one may spawn in melee - also another huge advantage, as less people are moving and less are taking damage.

If someone in ranged gets the engulfing magic debuff, they don't need to move out of a group - they just keep DPSing for twice the damage without having to run away from the group.

This turned our 70% Theralion wipes into an instant kill. Try it!

So she has 4,000,000 odd in GB and then 32,000,000 in BoT.... WTF

Comment by DaJungo

Alright, Rogues. Remember when Blizzard made Feint not suck anymore? Fights like this are what they had in mind. Glyph of Feint and Feint shine in many boss fights but this is one of the better examples. You'll be so amazed at how low your damage intake is during this fight just by actively using Feint and Cloak of Shadows.

-Time to dispel Blackout? Use Feint beforehand(Or CLoS)
-Targeted for a Meteor or someone next to you is targeted? Use Feint(Or CLoS)

Seriously, using Feint and CLoS will make your Healers adore you because they wan't be spending precious mana on you and you can pretty much keep yourself alive with friendly Lightwell tapping.

Just...for the love of god, do not use Cloak of Shadows if you get Blackout unless you're told to.

What i wanna know is Valiona and Theralion twins? or are they yet to give us our cataclysm twins?

Comment by 259313

Hunters can mitigate the damage from Valiona's Twilight Meteorites quite effectively, both by feigning death just before the cast finishes (This forces her to target someone else and start the cast over), or by running out of the group and using Deterrence with similar timing.

Thanks for your suggestion, we had a hard time wiping with the "standard" tactic, this one worked way better and we had both dragons down after a couple of attempts. Highly recommended over the one suggesting to have ranged grouped as well, which ends up in complicating the job in an unnecessary way.

Comment by adame

From a 25m perspective, with Theralion on the ground it's easyer for ranged to full circle and just have the ones who get meteor run into the mele to soke it.

We tried that in 10man, and made our job simple and straightforward. Highly suggested. :D

Yeah, confirmed, we underwent the same experience, so as we switched tactic we managed to turn frustration into an easily-achieved success. Recommended.

Comment by frohanss

A easy fight when all in raid manages to group up when needed and run away with engulfing magic.

Extremely simple way to take out Valiona and Theralion during phase 2.

/watch?v=pRn0AODL_MQ

I assume this would work for 25man as well if you had more people spread out, but I'm not sure. Anyways, check it out!

Comment by Putzahontas

While Valiona is on the ground, the basic idea is to stay spread out at all times to minimize meteor damage and clump up when Blackout hits someone.

Several classes have abilities that they can use to eat blackout so you don't need to bother gathering up. Mages can iceblock out of it, pallies can bubble, rogues can cloak of shadows, and shadow priests can use dispersion (spriests will still need to be dispelled by someone else while dispersed, but all the other abilities will auto-dispel the buff when used). The targeted player will need to make sure to be a /range 10 from others, though, as people who are too close will still take damage when the debuff drops.

While you'll still have to gather for some blackouts depending on who gets targeted/whether their CDs are up, we found that being able to skip a good number of them was very helpful in terms of both healer mana and dps uptime.

Comment by 792650

To be frank, the hardest part of this fight is the transitions. Both for that matter but more specifically when it transfers from Theralion to Valiona. Dodging the deep breaths and then having to stack up again for a blackout requires a high amount of coordination when factoring the fire already on the ground and that you'll most likely have Theralion's debuff up (Empowering Magic?). After running multiple attempts on the two, that is the most crucial part of the fight in my opinion. If you can master that portion of the fight, you should have no trouble downing the two dragons.

Just make sure you dispel Blackout fast when people are together to avoid useless meteor damage.

In 10man:
For the Blackout we had all dps/healers spread out even behind Valiona, and when the blackout was cast all dps moved to the tail and then out BUT only the dps moved, that made healing the meteorites/blackouts trivial as the healers didnt have to move.
The resto shaman in the group can drop a healing rain on the tail of Valiona preemtively and a couple chain heal will do all the trick.

Comment by thunderzebra

For the heroic version of this fight:

Blackout can not be dispelled. Instead, it only expires when the target receives a certain amount of healing (or if left on the target for 18s, lol).

For Grid users, this will no longer show up without creating a custom Debuff: Blackout status.

Comment by 250447

Can anyone confirm that Valiona is a girl? The voice of the dragon kinda reminds me of a male but i cannot find exact information!

Comment by MakaPL

Theralion has done a sexchange :<

Why downrate lol? Can't say that I think his voice was unique and now he is just nothing more but a cheesy bad-ass?

Comment by 457309

For Heroic Mode, does anyone know if the Twilight Realm's debuff Twilight Zone and the increased shadow damage taken from it apply only to people inside the Shadow Realm, or does this persist outside of the Shadow Realm as well?

Check this page, it is kinda confusing:

Comment by NoobIRL

Normal 10m (no achievement), how I do it:

1 tank,
2-3 healers
7-6 dps

3 groups:

tank, melee, rangedps/healers
(Yes, this can be done with less healers)

----------------------------------------------------------------

Everyone starts the fight with Valiona.

Tank:

1. Tank Valiona, stand at middle of the stairs.
2. If you are in front of Valiona when she starts casting Devouring Flames, move behind her and return to your position when she stops channeling it.
3. You do not have to move during Blackout.
4. After 2 Blackouts, move to center of the room while avoiding Dazzling Destruction (huge AOE mark will show up, you have a few seconds to move away).
5. Pick up Theralion and stand still unless theres fire on the ground around you.
6. When the raid warns you of Valiona casting Deep Breath, look up and look at which side of the room Valiona is casting it on - move AWAY from that side. She casts it 3 times.
7. Repeat steps 1-6 but with 3 blackouts this time. That is all.

Melee DPS:

1. Spread around Valiona and dps her.
2. Watch out for Devouring Flames, if Valiona faces at you, she is going to cast it at you. Run behind her to avoid it.
3. If you or someone else get marked with Blackout, have everyone but the tank stack behind Valiona.
4. Let a healer dispel Blackout and then return to your original position.
5. After 2 Blackouts, start moving to center of the room and avoid Dazzling Destruction (huge AOE mark will show up, you have a few seconds to move away).
6. DPS Theralion from the side. Stay stacked with other melee DPSes. This because you'll get marked with an arrow on top of your head for Twilight Meteorite, which deals about 120k shared damage to everyone around 6 yards.
7. Watch out for flames on the ground. Move away from them together with other melee DPSes.
8. When the raid announces Valiona casting Deep Breath, look up and look at which side of the room Valiona is casting it on - move AWAY from that side. She casts it 3 times.
9. Repeat steps 1-8 but with 3 Blackouts this time.

Range DPS:
1. Spread around Valiona and dps her.
2. Watch out for Devouring Flames, if Valiona faces at you, she is going to cast it at you. Run behind her to avoid it.
3. If you or someone else get marked with Blackout, have everyone but the tank stack behind Valiona.
4. Let a healer dispel Blackout and then return to your original position.
5. After 2 Blackouts, start moving to center of the room and avoid Dazzling Destruction (huge AOE mark will show up, you have a few seconds to move away).
6. DPS Theralion from behind. Stay stacked with other Range DPSes and healers. This because you'll get marked with an arrow on top of your head for Twilight Meteorite, which deals about 120k shared damage to everyone around 6 yards.
7. If Theralion casts Engulfing Magic on you, move away from the raid and wait until its over. You can DPS while you have the buff if no ones near you.
8. Run away from any fire you see on the ground and stay stacked with other Range DPS/healers.
9. When the raid announces Valiona casting Deep Breath, look up and look at which side of the room Valiona is casting it on - move AWAY from that side. She casts it 3 times. Stay stacked with your group.
10. Repeat steps 1-9 but with 3 Blackouts this time.

Healers:
1. Spread around Valiona, heal the raid.
2. Watch out for Devouring Flames, if Valiona faces at you, she is going to cast it at you. Run behind her to avoid it.
3. If you or someone else get marked with Blackout, have everyone but the tank stack behind Valiona.
4. Dispel Blackout and then return to your original position.
5. After 2 Blackouts, start moving to center of the room and avoid Dazzling Destruction (huge AOE mark will show up, you have a few seconds to move away).
6. Stack with Ranged DPS and Healers behind Theralion and heal the raid from there.
7. If Theralion casts Engulfing Magic on you, move away from the raid and wait until it's over. Do not heal others while you have the buff.
8. Run away from any fire you see on the ground and stay stacked with other healers/Range DPS.
9. When the raid announces Valiona casting Deep Breath, look up and look at which side of the room Valiona is casting it on - move AWAY from that side. She casts it 3 times. Stay stacked with your group.
10. Repeat steps 1-9 but with 3 Blackouts this time.

And a few tips to everyone:

Blackout can be dispelled without taking damage with abilities such as Cloak of Shadows - If you see someone moving away from the raid, they are probably going to dispel it by themselves, so don't go near.

If you get taken to twilight realm, find a portal and click on it to get back to the fight.

--------------------------------------

I usually have to type all these strats on raid chat if someone doesn't know tactics and I thought i'd better write it here and tell them to read it on wowhead instead.

Ah. TLDR version:

Spread, go behind Valiona when she starts casting Devouring Flames.
Stack on Blackout, dispel Blackout, go back to your positions.
After 2 blackouts, run from Dazzling Destruction (to the center of the room)
Stack on someone if you get an arrow on top of your head.
Move away from the raid and stop healing if you have Engulfing Magic.
Don't dps if you have Engulfing Magic and you are next to others. Move away with the buff to be able to DPS.
Don't stand in the fire.

Theralion

When the encounter begins, Theralion immediately takes to the air, while Valiona engages the attackers on the ground. The twin dragons share a single health pool, and each alternates between being airborne and fighting on the ground.

Grounded Abilities
Theralion uses the following abilities while on the ground.
- Engulfing Magic – Theralion twists the magical energies within an enemy spellcaster, increasing their damage and healing done by 100% for 20 sec.
  However, each time the affected player deals damage or healing, Engulfing Magic triggers a twilight explosion. The blast causes damage equal to the amount of damage or healing dealt to all players within 10 yards.
  In a 25 player raid, Theralion twists the magical energies of three enemy spellcasters.
- Fabulous Flames – Theralion launches a burst of twilight energy at the location of a random enemy. Fabulous Flames leave a circular patch of twilight fire on the ground for 45 sec., inflicting 18525 to 19475 Shadow damage every 1 sec. to all players in a 12 yard radius.
Airborne Abilities
Theralion uses the following abilities while in the air.
- Twilight Blast – While hovering overhead, Theralion continually launches bolts of twilight flame at the locations of random players. When a Twilight Blast impacts the ground, it explodes and inflicts 34125 to 35875 Shadow damage to all players within 8 yards of the impact location.
- Dazzling Destruction – As he prepares to land, Theralion mesmerizes his foes with swirling patterns of energy on the ground. Theralion then strikes each of these locations with massive blasts of twilight power, inflicting 14625 to 15375 Shadow damage to players within 12 yards and sending anyone caught in the blast into the Twilight Realm. If a player is already in the Twilight Realm when struck by Dazzling Destruction, that player dies.

Valiona

When the encounter begins, Theralion immediately takes to the air, while Valiona engages the attackers on the ground. The twin dragons share a single health pool, and each alternate between being airborne and fighting on the ground.

Grounded Abilities
Valiona uses the following abilities while on the ground.
- Blackout – Valiona surrounds a random player in a shroud of Twilight energy, absorbing the next 75000 points of healing on the target. When Blackout expires or a player dispels the effect, the dark energy explodes in a massive torrent. The explosion inflicts 975000 to 1025000 Shadow damage divided amongst all players within 8 yards.
- Devouring Flames – Valiona unleashes a prolonged breath of Twilight flame in the direction of a random player. Devouring Flames inflicts up to 90000 Shadow damage every 1 sec. for 5 sec. The damage diminishes on targets within the breath the farther away from Valiona they are located.
Airborne Abilities
Valiona uses the following abilities while in the air.
- Twilight Meteorite – Valiona sets her sights upon a random player and prepares to unleash a powerful Twilight Meteorite on them. When the meteorite lands on the player, it inflicts 292500 to 307500 Shadow damage divided amongst players within 6 yards of the impact point.
- Deep Breath – As she prepares to land, Valiona takes a deep breath and strafes from one end of the chamber to the other, engulfing a third of the room in Twilight Flames. Contact with this dark flame inflicts 29250 to 30750 Shadow damage, and draws the player into the Twilight Realm. If the player is already in the Twilight Realm when struck by Deep Breath, that player dies.

Twilight Realm

Being struck by Theralion's Dazzling Destruction or Valiona's Deep Breath pulls players into the Twilight Realm. In this alternate plane of existence, spheres of volatile twilight energy float around and detonate if touched. Collapsing portals appear randomly throughout the area, and players may use a portal to return to the material plane. Each portal disappates after a time.

In Heroic Difficulty Shifting Reality also pulls players into the Twilight Realm.

Unstable Twilight – Coming into contact with one of the floating orbs of twilight energy within the Twilight Realm causes it to violently explode. Unstable Twilight inflicts 39000 to 41000 Shadow damage to all players within 8 yards, but only affects players inside the Twilight Realm.
