The monk should have the wrench from the Taskmaster's room. Have them go around and disable all the machines they can without agroing Silverwing. The last 3 machines by Silverwing will require your pet class to pull silverwing so the monk can disable 1-2 machines, get away and FD. Once all the machines are disabled it is now time to pull.
The main tank should set up on Silverwing's left side. There is a wall and a dragon statue that form a corner there which is a easy spot to hold Silverwing and not get knocked back.
The raid should be slightly down the ramp at max range of the Wing Beat aoe. The main tank healers should be able to find a spot on the side of Silverwing that will prevent them from getting the aoe. If they are having trouble finding this spot then have them joust it or hide around the corner past the dragon statue.
Once positioned pull Silverwing and fight as normal jousting the Wingbeat AOE that will hit every 60 seconds (it is longer than the other windbeat aoes in the zone and hits just as hard).
Now during the fight people will be called to click on a 3 foot tall metal torch. He will call 4 people during the fight. First it will be a scout at 80%, then a mage at 70%, a fighter at 60%, and finally a healer at 50%.
The locations of the torches are:
Healer - At Silverwing's spawn location
Scout - Very back of the room opposite from healer
Mage - Near the ramp where the raid should be positioned
Fighter - Opposite side of mage spawn on Silverwing's right side.
Now when you are called to click the torch your screen will go blue. You will also not be able to see the little orbs floating around that stun and damage you. Because of this someone (preferably a healer) should be assigned as a guide so the people called can follow them safely without running into orbs.
The orbs will only be near the fighter and scout harvest points. The mage and healer that are called will not need a guide.
During the time the people are called to click the torch Silverwing will not take damage, but you can still land debuffs. Once the torch is clicked you can damage Silverwing again.
One of the tricky points is that when the fighter is called to click the torch at 60% the adds will also start to spawn. If you are lucky the off tank will be called to click the torch, the main tank can stay on Silverwing, and the monk can pick up the adds. If the main tank is called the off tank needs to rescue Silverwing. If the monk is called then have the off tank grab the adds.
The adds that come are Droag casters. Do not engage them until they get to the raid force or they will sit there and nuke you from a distance. From 60% on they will keep coming so the dps needs to switch between adds when they arrive and then back onto Silvering.
Now the tricky part starts: Silverwing will charm 3 people randomly. He will do it around 55%-45%, and then twice after that at about every 2 minutes. Swarm pets have been said to eat the charm but I can't confirm it works properly.
Dealing with the charm is the only difficult part of the fight, but if the wrong 3 people get charmed its pure chaos.
A quick rundown of the fight is as follows:
80% - Scout will be called to harvest
70% - Mage will be called to harvest
60% - Fighter will be called to harvest
60% - Droag casters show up and keep coming
~52% - First possible charm
50% - Healer will be called to harvest
~32% - Second charm
~12% - Third charm
Silverwing updates mythical weapons for Guardian, Bruiser, and Illusionist.
Note: as your are running to the torch locations as long as you follow the wall exactly you shouldnt get hit by the floating balls. If you start near the wall and inch your way closer to the torch you should get within range to harvest it without getting the balls. If someone dies when they had the torch vision you can not proceed and you need to wipe Silverwing and start over. Many guilds pull Silverwing outside of his room to the hallway just outside of the Fighter Torch area up the ramp. Be prepared to swap tanks if your MT is called to harvest the torch.
The following crude drawing should help you understand where things are located. There are switches to the left and right of Silverwing that deactivate the orbs, but honestly cause more issues than solve as you can avoid them easily. You also dont necessarily HAVE to deactivate the machines near the healer torch if the healer who has the blue vision just goes right down the middle of silverwings little pad. It takes about 10 seconds to harvest the Torches. Remember if you keep to the outside of the walls you should be safe from getting hit by the orbs, but it occasionally does happen. You dont need a healer escort to the torches, if you get hit by the orbs healer or not, your probably going to die and need to start over anyways.
Depending where you choose to fight Silverwing either in his room or out in one of the hallways, remember this, you want to pick the quickest route to get to the torches. If you fight Silverwing in one of the hallwas dont forget to deactivate the machine right in front of Silverwing so people can get to the otherside of the room quickly without having to run the long way past the Scout Torch area.
