Dusk ordeal mission w/mountain of smiling bodies

[OmegaJV]

Last time I tried the crimson dusk rolled through central command and got it to escape containment, it did not go well. Any advice would be appreciated.

Here is some info I think may be relevant:
-I have Der Freischütz & Little Red Riding Hooded Mercenary.
-I have the aleph gear from mountain of smiling bodies and judgement bird.

The easiest way to deal with MoSB is to park someone (or several people) with the effective E.G.O in front of its containment unit so that it can be suppressed immediately without having it snowball into the stronger form. Should be easy enough.

try not to take Mosb, Hentai Slime or White Musician unless you want to get their ego gear.

Trust me, it will make your life much easier in the long run.

Get MoSB's EGO suit.
Whoever you put it on will act like a corpse roomba and eat any corpse they walk over, buffing themselves...which is nice, but secondary to the fact that any corpse they eat can't be eaten by MoSB.

Other than that, you just gotta suppress MoSB the moment it escapes so it doesn't run off and eat corpses. MoSB is the weakest of all the alephs as long as it doesn't reach stage 2 or especially stage 3.

Wipe out all clerks in the same department so Mr. Meatball never reaches stage 2 beyond.
Send one agent with Aleph gear in front of his door should be enough to deal with his stage 1 form. Or send more less-geared damage dealers to be safe.
Now you know how he works, get his gear developed and refund him back to help your life, if you still have the chance.
