I can't tell you when the last time was I died on this template, every single one that I play maintains Glorious Lord just from maps
Isn't the player that opens up the chest pretty much the sacrificial lamb and dies right on the spot. I think I remember doing 20 Level 6's where one time I got out alive. Almost identical to the player who tosses the White Net that summons the Leviathon. Got nowhere to hide 
The initial spawn pops up when you dig the trunk up, not when you open.
Here's how I solo a tmap:
1) Recall to spot, test dig to make sure I'm at the right spot but don't finish the dig, kill off or lure any random spawn hanging around
2) Mark a rune from the spot I'll be digging from (how many times this has come in handy I can't tell you)
3) Find a route I can run without getting stuck. I prefer a straight line. I test a couple directions from my marked rune spot until I figure out the best way to run. You don't want to get hung up running from 3 Ancient Wyrms and a Balron!
4) Drop two EV's
5) Dig up the trunk
6) Wait a couple "ticks" of the trunk rising and prime a Peace
7) As soon as the trunk pops and the spawn pops out there is a second delay before they target. In this second the EV's attack, I hit my area peace, I run up my route a couple of screens, and I Invis.

Finally, slowly work back picking the spawn off with provoke, ev's, peace, etc.
I usually take everything out of the trunk to get as much spawn as possible because the items on the spawn are often as good or better than the items in the trunk. The crap I drop in a corpse, not the ground - makes it a lot easier. Not sure how much of this will need to be adjusted with the new changes, I'll probably wait until production before playing with it.
Hope this helps.

<edit>
Forgot to add, Rheeanna, I still haven't played with the whole Bard mastery thing. I figured I'd wait until a couple updates went by first. I do need to get in there and play with them asap though.
I often play with a luck suit because the goal of this process is to never get hit but, if you do get hit, you "ooOOOooOOOooo" quickly! If Imbuing I would go 100 LRC, max +Mana and MR as you're running with little to no Med, and resists. Skills on the jewels open this temp right up as well, probably get you to not have to soulstone Cart off to get Disco on.
Anyhoo...
