High Astromancer Solarian
Before we start its a good idea for everyone to wear some arcane res gear without gimping themselves too much. A great item to have is the Violet Badge, which everyone should have! This item alone will negate 3 Marks of Solarian.
To start the fight we will split into 2 group. Melee and ranged. Melee will be stacked on Solarian and ranged will create a slightly loose ball.
Phase One is a DPS dream. There is NO threat table on Solarian herself. Go hard! Roughly every 45 seconds Solarian will cast Blinding Light causing damage across the entire raid. This and the random targeting of Arcane Missle will be the hardest thing Healers will have to be on top of for this fight.
Dealing with Wrath of the Astromancer. We will have 2 Arcane Resistance Tanks that will soak these charges. These tanks will be away from the rest of the group. If you are infected with Wrath of the Astromancer you will need to run to these tanks until it falls off. You MUST be close enough to the tanks for you to pass it on to them and NOT the raid. Once it does you need to run back to the rest of the raid.
I cannot stress enough how much you need to pay attention here. You need to move very quickly during the time you get the debuff to the time you drop it and run back to the raid. If you fail to move to the tanks you will give it to the raid and might cause a chain reaction. If you fail to move away from the Arcane Tanks after dropped the debuff you have a high possibility on getting the debuff again and that will result in your death.
After 50 seconds, Solarian will phase out and teleport in 12 Solarium Agents. Everyone should collapse to a tight ball. Hunters should drop frost traps and a Paladin tank pick up the adds. Dispose of these adds quickly! When Solarian comes back she will bring 2 Solarium Priests. These can be STUNNED and their Heals should be INTERRUPTED. The tank can have the priests stacked on top of Solarian for cleave damage but the priests must die ASAP.
All of these skills continue until Solarian reaches 20% Health. At this point Solaraian will transform into a Void Walker no longer casting any of her arcane abilities. She now has a threat table!!! Fear wards should be placed on the Tank and tremor totems should be dropped. The fight now becomes a tank and spank! Keep everyone alive and don't pull off the tank and GG!
