What will I be fighting?
Dreams and nightmares features the following enemies, that are mostly copies of their Tier 2 versions:
+Wolvers = not so bad, cannot teleport
+Toxigels = spike attack = extremely bad, beware this enemy
+Thwackers = watch for their spin attack; these get stuck to walls at low health
+Lumbers = extra large and tankier than usual
+Dust zombies = no breath attack
The first 2 levels are running levels, wherein you want to miss the boxes (or get them if you feel the urge, they contain nothing but crowns ever, no rarities), but the last level is a relatively difficult arena.This last arena area has waves that alternate between being "solved" by shadow and piercing like so...
Wave 1 = weak to shadow
Wave 2 = weak to piercing
Wave 3 = weak to shadow
Wave 4 = weak to piercing
etc.
Since it's an arena, bombs are a great idea here, which leads us to the EZ-Mode loadout:
Chaos/Black kat = there's not much status beside poison, and no one damage type you can really prepare for.
Dark Retribution = Shadow bomb of choice
Dark Briar Barrage = Piercing bomb of choice
(Optionally) Some kind of normal gun/sword to kill stragglers with
ALL THE HEALTH PERKS + TRINKETS = NO VITAPODS DROP HERE
Shield = whatever you have, but preferably normal/piercing/poison = yellow tortodrone shield or ironmight or so..
Other bombs to consider are ash of agni (which melts most everything here, except for the gremlins) and the various shard bombs, since the shards can provide a decent way of damaging things as a support. Nitronome and Irontech also work for it.
The more advanced loadout that you might have is-
Chaos/Black Kat (again)
Vortex-of-choice
Iron Slug or brandishes or whatever
This "advanced" loadout is much higher risk, much higher reward. It outdamages all of the above options, but has a tendency to get you hit. To counter this- USE SERAPHYNX'S HEART ATTACK CONSTANTLY
Solanacea has a good image of this strategy here
But I didn't craft any bombs! Or Seraphynx!
First of all you should probably consider buying Operation Crimson Hammer, either with cash or with ce you get from Vanaduke runs the arcade, wherever else.... nor is Dark Briar Barrage particularly hard to obtain, and you can always get a default+boring seraphynx for some energy, and then get heart attack to it's max. It's not so bad of an idea when preparing for the mission.
Second of all you can piggyback off of someone else using your various non-bombs that you crafted. You probably have...
Barn-dishes- Watch out for standing still while attacking as that can get you hit. Mostly just finish things off for the bomber.
Acheron- Same deal as above, but shadow... which means it counters all but zombies. Congrats.
Blitz Noodle- Don't charge unless you know you won't get hit... just use regular shots for less damage, then move on quickly.
Grim Repeater- Same deal as blitz... but it completes them. You can do the entire thing, albeit slowly, with just these 2.
etcetera, etcetera
These work just fine, but are going to be quite a bit slower and harder to use than the aforementioned bomb loadouts.
No one ever wants to join the mission.....
Well go find some friends! Join the arcade discord server- https://forums.spiralknights.com/en/node/113634
Then go and find someone experienced to run DaN with. After a few runs of this you should be able to get the hang of it.
Remember that practice makes perfect, and that learning is a huge part of the game.
