Here is my strategy for the STAGE 3 : It worked like a charm. Hey there, i think i found a rather "easy" way to get throught that phase and it doesnt require cheesing ! It requires practical sense and synchronicity which is a good to have ! First time we reached that phase, it took us maybe 10 to 15 tries to get it done. And that strategy is what i found was best. EDIT : Here's an ugly drawing to help you understand all this : http://imgur.com/WZ7MZJ7 The Phase As a reminder, this phase is about killing the main wizard that hangs out with a glowing crystal in a weird energy prison we can't enter in. And obviously, as soon as you get in the room, you have a limited time (between 2:30 / 3 minutes. That invisible countdown seems to start as soon as you shoot an enemy or a friend receives damage ) to kill her otherwise she'll sing you a nice lullaby that will have you sleeping forever. Her singing also starts as soon as you destroy the 2 shriekers so the sooner you can destroy them, the longer you'll have to fire at her (Need more testing but i think it triggers it as well). Now, the mecanic of this phase is that you need to get access to the main wizard (cant remember her\his name) and then spam it like if it was a damn pissed off gorgon (which she kinda is). To do that you have to break the 2 shriekers located on each side of the crystal room. But of course those shriekers can only be taken down after their dedicated wizards are killed. So, now with the strategy. The strategy First, you need to split in 2 groups. Try and make them as logical as possible. Having one titan each side with WOL is a very good thing if possible. Basically, each group will take cover in a position (those platforms up there) on each side of the room. Allowing for a quick and safe destruction of the wizard on both side and the mobs that come with her. So let's go : 1) To avoid any complications, kill the first 2 knights to avoid being OSed when running to your safe spots. (Take the time to charge your ice breakers and they'll drop in seconds) 2) When done, each group runs directly to its side and takes the stairs. Dont mind mobs or knights on the ground. When you reach the top of the stairs, reverse and jump in those high vantage point rooms. 3) Kill the ice rocket knights and clean a bit on both side => ATTENTION, the group that goes left tends to aggro some more mobs that will stay below them, right group has to shoot those mobs whenever possible. 5) While cleaning is happening, one guy on each side has to go lurk a wizard out. Just go halfway in the room and go back to the high vantage point. Watch out for the knights that will spawn along the wizards. 6) SPAM ENEMIES !!! Use WOL, rockets (but keep some). Ice breaker is your best friend to be honest. So is VOC. They usually stack right outside the room where you went to lurk the wizard and are sitting ducks there. Only the wizard can hurt, the sword guys are just standing there. 7) When the wizards on both sides are dead, clean the remaining knights. Then move closer to the shrieker room on both side. 8) Have a First group destroy its shrieker and immediately go back and join the other group. Nevermind the mobs around the first shrieker, fire 1/2 rockets and a few bullets and go. 9) Have 4 of you simply kill mobs outside the room. The 2 remaining guardians kill the 2nd shriekerFROM THE OUTSIDE to avoid losing 3 dudes from its death shrapnels => ATTENTION : the shrieker shrapnels that spawns when it s killed are deadly as -blam!-. When you kill the last shrieker, the wizard will start her lithurgy and you have 30 seconds to kill her. 10) SPAM DA BITCH. Everyone should go in with rockets and fire in the hole. You need to clear a line of sight on the wizard and spam her from a distance (again, IB). So have 2/3 guardians go full IB and focus on her from as soon as you can hit her. The rest should spam their heavy shit on the knights\mobs before aiming at her. She isnt that tough, we made it on a try where we thought we took too long. But turns out we depleted half her life in 6/7 seconds. 11) Dont Profit........ no loot. WTF bungie ! 12) Gather around the crystal and sing Kumbaya In the end, it's a fun fight. The key is to balance speed and safety. But try that strategy, the higher vantage point will allow you to really see what s happening and allow for a sweet room cleaning and synchronizing both sides as you have LOS on the other group. Let me know what you think guardians !
