Phase 7: Gate Lords
This part can be the most confusing and challenging for your teammates. Working together here is the most quintessential of the raid. To start off, when you run through the door you will find two gates. On the left and on the right. The left can be referred to as Mars, Red or Left. The right can referred to as Venus, Green or Right. Either way you need to make sure your entire team understands these identifiers.
The strategy that we have implemented that has lead to the most number of clears without wipe is also the easiest ( as long as you remember to stay the fuck alive ). Two people will go into Mars, while the other four stay outside and prevent the control plate from being seized. ( IF the control plate is seized, you will have RED oracles spawning above the gate that was captured ) The idea here is to get the gatelord in Mars down to a sliver of health. I'll explain why later. But it's essential that you do not kill the Gatelord. Just bring him down to a sliver of health. Once his health is down, you return through the gate and go to Venus. Here you move forward and eliminate enemies and kill the gate lord.
ONCE THE GATELORD IS KILLED A RELIC WILL SPAWN IN THE CENTER OF THE MAP. Make sure that you are quickly out of the portal. Cleanse both who went in. From this point the person with the shield should move to the top of the map to kill the minotaurs that are spawning to sacrifice to the relic. They are the only enemies that can be sacrificed. Two slam attacks with the shield is enough to take out the minotaurs. Your job is easy but essential. The remaining person runs into Mars, while the remaining people cover the gates and look for oracles. Once inside, the person fires a single rocket into the gatelord, killing him in one hit. Grab the shield. From this point you can either wait till the cleanse buffer is up or make a break for the gate. Your call, I've done both and succeeded both times.
Once the final shield is out of the gate, everyone ( save for the first shield wielder ) needs to go center as there will now be two additional spawns, shooting out Praetorians. Hold this spot for 1-2 minutes and this Phase will complete. Enjoy your loot.
