Vault of Glass: Day one progression.

Congrats guys, we're doing great. We've made it as far as the elitist and farther than the masses. We still have a long way to go. Study the fight below and we'll be ready for tomorrow. Also, if you can add the other guys to the group and clan so we can get the clan credit for it and they can see this post. Boss 4 - The Gatekeepers: Activate one of the two portals. One will be a desert version of the room you were just in, and the other will be a rainforest version. The portal takes some time to open, but only requires one person in its circle. Once the portal opens, send only one or two people in. You'll need the rest to protect the portal and the column (more on that later). Inside the portal, you'll see some adds and another Gatekeeper. Kill the Gatekeeper ASAP while heading towards the back of the room. If you take too long, your vision will turn black and it'll be nearly impossible to leave. Once the Gatekeeper dies, a Relic will drop. One player will need to pick it up and exit quickly before he can't see anymore. Once he exits, the grenade key can be held to clear the vision debuff. Send the Relic player and one other player into the second portal. Just like the first portal, kill the Gatekeeper and have the player without a Relic collect the one that drops. However, the player with the first relic can clear the vision debuff, so you don't need to rush as hard. Outside the portals, a column will appear in the middle of the room sometime after you open the first portal. The Vex will attempt to sacrifice themselves to it. The players outside must defend it until both Relics are collected. If any Vex manage to sacrifice themselves, an Oracle will spawn and must be killed immediately. -EDIT- Both Relics must fire their supers into the column to proceed. Once the column disappears, the real fight starts. Boss 4.5 - Atheon, the Devourer of Hours: Atheon appears at the top of the stairs. With his appearance, both the Relics disappear. Around 15 seconds after he appears, he will teleport the three players furthest away from him to one of the two portals, as well as spawn several Supplicants in his room. Inside - The players will appear across the room from the exit portal next to a Relic. One player will need to pick up the Relic in order to cleanse the vision debuff. The adds in the room deal lots of damage, so approach carefully. Seven oracles will spawn one after the other. Kill them quickly while making your way over to the exit portal. Once they're killed, everyone (both in and out of the portal) gets a buff called Time's Vengeance. Make sure to cleanse the vision debuff again once you leave the portal. Outside - Send one player to open whichever portal the teleported players are in. The other two need to kill the Supplicants. Supplicants will sometimes shoot you, but their true danger is their self-destruct. They're very quick and tend to camp around the portals. If not dealt with, they'll kill the inside players before anyone can react. Once all six players are outside, you need to do as much damage to the boss as possible. Damage to the boss is increased and everyone's supers and grenades refresh in two seconds as long as Time's Vengeance is active. If not done quickly enough (I'm not entirely sure what the qualifier is), the boss will enrage. The Relic has a super attack that, while very vulnerable, can deal huge damage to the boss. Once Time's Vengeance wears off, the three players furthest from Atheon will again be teleported to one of the two portals.
