items marked as "chest" are all the possible spawn locations of the first chest.

I was about to start a thread asking if the first chest was too easy. I managed to drop in, run to the first door on the left, grab the chest, and walk away with No Land Beyond and the raid Titan mark in about 5 minutes (most of which was loading, falling, or waiting on the bridge to form). But if the alternative is trying to check out each of the seven possible rooms while trying to keep your group together and alive, I think I'm cool with them letting it occasionally spawn in that first room.

From the Reddit Post:

...maybe with the exception on the rock at Lamp #2 the allows you to jump up to Lamp #11

Has anyone here tried this? That cuts out half of the lamp room!

Hunter in my group did it earlier.

Cool. How practical do you think it would be for an entire group to attempt? I'm not sure how much time it would actually save unless everyone nails it on the first try and you can avoid getting overrun while everyone waits to jump, but it would be fun to try!

It's one of those things that everyone will probably mess up the first time because of how hard it is to see.

I purposely no longer use any raid boots with a heavy ammo perk because you just lose heavy ammo on death, wipe, cut scenes, go to orbit, etc... There's nothing like wasting an entire Heavy ammo synth because you reload, shoot a rocket or two, die/wipe and then have to wait another 2 minutes til you can use heavy ammo synth again.

While they take turns jumping, I'm sure plenty of Thralls will end up with the flavor of glove in their mouths...

note that lamp 2 is also the lamp cannon (youtube video)

A buddy and I hit this with our alts last night. He got Radiant Energy or Shards, which is nice to get; I got an Dragon Breath! Woo! I've never been so excited about what will (hopefully) be a long lasting case of halitosis.

So, for the two of us that's 4 checks of the chest & 1 exotic. I wonder what the drop table for that chest is like.

i've gotten the 1st chest 4 times, and every time i've gotten the warlock bond, and either shards/energy

I managed to score a No Land Beyond from that one this week. I was excited until I started using it. Now I'm thinking I would have rather gotten more energy.
