Here's the gist of how I killed this, I was 909 equipped. Even bad players like me can get their challenge appearance as arcane mage!
Talents: Amplification, Mana Shield, Incanters' Flow, Resonance, Chrono Shift, Erosion, Overpowered
Mana Shield lets you spam your barrier and avoid being whittled down by attrition. Chrono Shift lets you get sprints when you need it. Resonance is just for cleaving damage. I swapped to Gravity Spiral to give me more evocates for mana shield, cord of infinity for burst on the runeseer.
This is NOT a dps race, except during the soft enrage at the end when the Runeseer spams his shield.
You get a special debuff in this encounter giving Polymorph a 20 second cooldown, but it no longer heals its target. Only Sigryn is vulnerable to polymorph, the others are immune.
Three things will happen in this encounter at all times.
1:Every so often a Val'kyr will come down and drop a yellow health globe to heal you if you run over it. Only lasts a few seconds.
2: A wall of Val'kyrs will charge through the arena, there's a clear gap, hits for about 3 million. This can happen during other abilities and it sucks.
3: Runes will spawn in the middle. Some will be smaller than others, they shrink over time and do 3 million damage if they shrink to nothing. This is a great time to use chrono shift and arcane barrage for a sprint. You can also use displacement to get extra blinks to get these.
The three bosses take shared damage, but the Jarl will die first due to his lower health pool. The bosses will become empowered one at a time and do an emote yell indicating they're empowered. The empowered boss will use something deadly you need to pay attention to.
Sigryn: She'll cast Blood of Her Father. This lasts 20 seconds and does 700k a second to you. You need to counter this by polymorphing Sigryn. You can't spam polymorph when it comes up or she'll go on DRs and go immune. Save polymorph for this. I suggest using a /cast [@focus] Polymorph macro and making Sigryn your focus. She also puts green shit on the ground when not empowered.
Jarl Velbrand: Either goes berserk increasing melee damage done by 500% or something stupid, or does a whirlwind that pulls you in and makes you dead if you go too close. Countered by kiting or running. Suggest making a /tar Jarl /cast Slow macro for him. Also throws annoying axes around when not empowered.
Runeseer Faljar: Gives himself a damage shield for ~6 million damage and does a 20 second cast that kills you at the end unless you break the shield and interrupt. Advise having frost nova up to give yourself room to dps him during it. You can't really save cooldowns though since he'll cast it more often than your arcane power and mark of aluneth cooldowns come up. Also he spams a meaningless nuke on you easily absorbed by prismatic barrier with mana shield.
Basic strategy: On the pull you can safely polymorph Sigryn and do your opener. After this you're just dealing with the abilities as they come and focusing on not taking damage.
This is not a DPS race. You'll get all the damage you need from occasional arcane blasts and missiles when you have distance, and arcane explosion and barrage while kiting.
Keep slow or chrono shift up on Sigryn and Jarl when they're chasing you and remember displacement and frost nova to keep distance as needed. When runes come up make sure to barrage to get a sprint to grab them all.
When the council gets low on health Sigryn will emote about empowering all her advisors, which actually means a soft enrage in which Val'kyr healy bubbles will not spawn and Runeseer Faljar will spam his shield over and over again, which is a challenge to dps down repeatedly. Try to save frost nova to create distance to cast, and space your cooldowns out to deal with it. Val'kyrs will come during it and it will suck. You can polymorph Sigryn freely now, but she'll go immune eventually. If you aren't going to get a shield down, ice block can save you once.
Final tip: Leaving the circle resets the encounter, but the bosses won't respawn and you'll need to exit and re-enter to try again.
When Sigryn hits 19% you win.

Pet - Doomguard
Legendaries - None mandatory.
This fight has no phases, just a large number of mechanics which must be managed correctly in order to succeed.
Main Boss: Will begin channeling an AoE ability that will kill you almost immediately. You MUST crowd control her either by fear or stun to stop this damage. She will also throw spears which create pools of fel on the ground, but these can be ignored.
Axe-Thrower: Will begin fixating on you and will melee you for extreme amounts of damage, do not let him get close during this ability. He will also begin channeling a whirlwind which will pull you in and kill you very quickly, you must run out of range of this.
Caster: Will begin channeling a spell which cannot be interrupted until you break her damage shield (save TKC for breaking this shield). You must interrupt this ability.
General fight mechanics: 3 runes will spawn on the floor in varying sizes that must be ran over to negate. Prioritize running over the smaller ones as they will expire first and do massive damage. Additionally, a wall of Valkyrs will spawn in a random direction around the arena, stand where the gap is to avoid damage. Small glowing golden orbs will spawn around the area which will give you free health and can be used should you accidentally miss a mechanic. The main difficutly of this fight is that many mechanics overlap or time to be one after another. There are no important DPS checks or burn windows, this fight is simply attrition. After a certain number of mechanics have been dealt with, the bosses will no longer cast special abilities aside from the caster's shield and ability which must be interrupted.

To defeat this encounter I used Sephus's Secret and Roots of Shalladrissil. I honestly believe that the encounter would be a lot harder without a healing legendary.
My Item level is 900, with 4pc tier. My armory is here: http://us.battle.net/wow/en/characte...derfall/simple
Step 1: Set Sigryn on Focus, she will remain there for the remainder of the encounter. You will be hexing her when she goes demo mode.
IF you need a focus macro, here is one for you
/cast [@focus] Hex
Step 2: Copy the talents @0:15 seconds. Use healing rain on cooldown, you'll need all the passive healing you can get here, as there is no enrage timer.
Step 3: Cleave down Sigryn and the caster together until the Axe guy enrages. Cap angry axe man and wait for runes to spawn.
Step 4. Kite angry axe dewd around the room while you clear two sets of runes. Stack the mobs back together and hack away.
Step 5. As the second runes spawn. Use the focus hex macro to mitigate damage from demo-mode Sigryn. Stack minor mobs and cleave
Step 6. Save Doomwinds for the shield. You might have to burst it down while he's standing in a void zone.
Step 7. Save Cap for blade storm or enrage.
Step 8. Watch for Valks
Step 9. Watch for Valks
Step 10. Watch for Valks....
Step 11. When the fell begins to ramp up and you can no longer comfortably cleave down the shields, re-hex Sigryn. She will continue to call valks but she wont throw the spear. This makes the remainder significantly easier and will allow you to finish the encounter without much hassle.
Congrats on your new weapon skin!

There are 3 mobs, which share health (supposedly). Sigryn has to reach 20% for the fight to end.
- Jarl Velbrand melees you for a little bit, and throws spinning axes that deal about 500k
- Runeseer Faljar casts Shadowbolts for about 100k, and puts some fel pools on the ground that tick for about 400k every 0.5 seconds if you stand in them.
- Sigryn occasionally does a knockback ability on you.
- Golden yellow orbs periodically drop in the arena. I think these heal, but I didn't really need to use them.
- 3 shadowy runes periodically spawn. They shrink in size over time, and when they shrink to zero, they explode for about 3 million damage. Running over the runes makes them disappear without taking any damage.
- As an Assassination Rogue, I got a buff that reduced Blind's cooldown to 30 seconds (and its duration to 35 seconds).
- Sigryn periodically empowers one of the enemies (she can empower herself).
- Empowered Jarl gains a BIG damage buff (500% or so) but reduced movement speed. Kite, or facetank using something like Evasion.
- Empowered Runeseer gains a 5M absorb shield, and starts a 20-second cast that, once completed, performs a massive AoE nuke that will probably 1-shot you. The cast is uninterruptible while the shield holds. Either break the shield and interrupt him, or just use an immunity right before the cast completes.
- Empowered Sigryn continuously pulses massive unavoidable damage for 20 seconds. This is where I used Blind, which stopped her from doing the damage.
- Eventually, walls of Dark Val'kyr appear and, after a few seconds, rush across the arena, dealing lethal damage. Find the gap in the wall and stand in it.
- Jarl performs a Bladestorm ability that slowly pulls you towards him. If you're in melee range, it deals about 900k Physical damage per second. Run against this to avoid being sucked into melee range.
