So I posted a similar question previously ([How can I suggest the DM stop trying to kill us?](http://rpg.stackexchange.com/questions/62911/how-can-i-suggest-the-dm-stop-trying-to-kill-us)) which was just about general gameplay; the outcome of which was that is just how the die rolls, which is fair enough.

However, now that we have reached our "final quest", phrases like "some of you may die" and "I *am* going to kill some of you" have started floating around.

Now, this dungeon was designed for five level 5 characters. Our group consists of four level 5 characters, and one level 4 character, so the dungeon is *already* over-leveled. Additionally, we played one session with one player missing, and we took a hefty blow in that session, due to his absence. (Not blaming the DM for that one, that's on us).

Additionally, the DM has stated that resting is out of the equation. If we rested for even 20 minutes, the bad guy would send more minions our way, or even take a rest himself.

So - our current situation:

- One character is unconscious, and has spent all of his abilities, plus has a "permanent injury" waiting for him when/if he regains consciousness (Fighter - Battle Master)
- Two characters are at half-health, with 3/4 of their abilities spent (Rogue - Assassin and Fighter - Eldritch Knight)
- One character is at minimal health, with most of their abilities remaining (Barbarian)
- One character is mostly fine (the perks or missing a session) (Barbarian)

We're halfway through the Dungeon, resting is out of the question, and the Boss is holding the surrounding area under siege with a doomsday death laser.

Apart from an all out retreat (where we would still have to take our chances trying to avoid the death laser), there seems to be little chance of survival, but none of us really want to die, especially when we're only at level 5!

What could we do to attempt to prevent this from happening?
