My team and I had the Crota raid finished on all 3 of our accounts by Friday night/very early Saturday morning. I have also read some of the comments and tested some theories. Here is what I know and some suggestions/tips... [b]The Abyss:[/b] My team found 2 chests in the this section. We were exploring after we built the bridge. We checked in the two platform doors before the final two lanterns and bridge sync plate and there was a chest and there was also one in the beginning next to where you drop in before the first lantern in the 1st door. Facts I know about this... 1. We had beaten the section already before looking for the chests. (bridge was built, and we had touched the light and received loot) 2. Everyone had already obtained the first chest to the left prior to round start/completion. 3. One person died during the section, was not flawless. 4. Not everyone ignited a lamp. 5. Neither chest gave loot. (we are assuming the two chests must be opened during activity and before completion... in testing) 6. Went back to the beginning and one of the chests were in the 1st door to the left, there was no orange light above the door. 7. [u]I highly suggest if you have an at least decent LED tv to turn your screen brightness in game to max, this makes seeing extremely easy![/u] [b]Bridge/Gatekeepers:[/b] Not much to say here. Facts I know... 1. All 6 of us crossed the bridge and killed their gatekeeper with the sword. 2. People did die, was not flawless. 3. There is an invisible wall when trying to get to the further out pillars, you hit it and fall to your death. (Blade Dancer and Striker classes attempted with) 4. You can leave and rejoin your other characters once you get the 2nd known chest in the gauntlet hallway at the end. Make sure 2 people stay in though, one to stay next to the chest so it doesn't despawn and the other to revive teammates when they rejoin. [b]Death Singer:[/b] Didn't do much exploring during the fight, but did a lot afterwards and found no chests. Right and left sides are as if you were coming out of the door on the bottom and looking towards where Crota will be summoned. Strategy I know that works... 1. Rush past all adds down low and have 5 people go left and one person go right. 2. The 5 person team will end up aggroing all the adds and pulling them to the lower left side of the map. 3. Quickly kill the wizard and the shrieker on the left and then gtfo. 4. The right person will only have 1 knight to watch out for in the beginning, so run in shoot the glass and aggro the wizard. 5. Run out take cover and kill this wizard. 6. Once both wizards are dead have all the team rush right and kill the knights and acolytes inside the room, because all outside adds are on the left side. 7. You can run into the room and jump above the doors in the crystal room, this keeps most adds from dealing you damage and you can get a start on the Death Singer while your team kills the adds. 8. Suppression grenades work great against the Death Singer, it stops her from shooting for a short time. [b]Crota Fight:[/b] Did not find any chests yet in this area. Have tried some suggestion seen in here though. Facts I know, or thing I have tried... 1. No chest appears after killing him with no one dieing. 2.I have obtained the sword and went back inside and attacked the crystal also tried the suggested special attack... nothing happened. 3. I am still trying to see if I can get the sword up into the 3rd floor to attack the gatekeeper. If you have any questions please ask. If I was confusing at any point let me know and I will clarify. I hope this helps, and I am hoping to hear some great feedback and tips like I have left. Let's find these other chests!
