2 Phases Guardians of the prime phase. And Sisters Phase.
Phase 1. 5 minute timer to kill 9 guardians of the prime, loot 9 items and hand them all in.
The 9 primes drop items with their effects. I.e. mob 6 is nearly spell immune if you hand that into the sister your killing she will be nearly spell immune.
All 9 items must be handed in, I assume 3 to each sister though i've heard it can be done otherways.
Mobs 5 7 9 all resist slash, and pierce and are weak to blunt.
Mob 4 casts a viral dot, use puratas on MT to keep it from spreading.
Mob 8 silences, ae ramps and blurs. Zi-thuuli style tank him...2-3 tanks fight for aggro.
Mob 1 has a super nasty 12 dd + fd proc. We burn this one fast. I'd suggest alandaring and Spellshielding your tank.... Make sure tank has 35% spell shield worn too.
Mob 2 is like mob 1, but not near as bad, 10kish ae, faces where the most people it can see to ae. like 30 sec recast. just keep groups healed.
Mob 9 randomly picks people to shadowstep to and kill. Only way to handle it is to have EVERYONE gather at one set point and kill it. 1-2 people may die to the shadowstep but fast taunts can save them.
We split the mobs Casters and Melee. Casters Kill 1, 2 7 8, Melee Kill 4 3 5 6 then we all kill mob 9. If you have more melee dps on a kill, have casters just kill 1 2 8 and have melee kill 4 3 5 6 7.
I don't have a exact hand in order I don't do it. We have 2 people that normally do it. Its diffrent depending on who does it, what we get. Both are killable.
Phase 2. Kill the sister.
No timer. Its just kill the remaining sister after they fight.
I know the items like bp shield and such make the sisters resist melee minus blunt. Greeves make that sister attack first...shield blocks sword. But not much other then that.
1. I know the sister we kill has the stave from mob 2, and the shield. The other item isn't visable. This kill is fairly inteisive but straight up. The sister will turn to face where the most people are and do a small beam style ae that hits anyone in the beam path. Have healers and such hide behind a wall, pin the sister on the other side of the wall. Dps hides if they get low and spread out so ae doesn't hit too many at once... Spell shield and alander on MT.
2. Sister holds dagger and has viral dot from mob 4. This sister is a easy win, or fast lose fight. Use puratas on mt keep him cured, we puratas 2nd tank too. If one tank dies it MUST go to 2nd tank or your viral spreads and raid wipes faster then you can blink. Its rather easy to have some ranger over aggro and get the viral and wipe the raid. I prefer sister 1 simple because this one, though easier, if you mess up once...its a wipe in seconds.
Edit
If you need more specifics ask, other then hand in's, I don't have that, but if i can find out I'll post it. If anyone needs more info on any raid before sol 1 PM me or bump the post. I've done basicly everything pre solteris.
