Frost. Goodbye armour and 6-8 cold procs is basically a Gloom the Demos can't pulse off.

Not sure about the replay versions but most quests (the few that do allow groups, most anything from the last 5-6 years is solo only) should progress together.

Archon Hunts are roughly equivalent to mid-tier Steel Path.

The Fulmins kind of so so (magazine is a bit small and the recharge takes a bit) at dealing with them. But a Hunter Munitions build should work. The Fulmin itself isn't great at the viral so a primer would go well.

The Archons themselves can be attritioned with nearly anything (even Operator), though there are speedier builds out there for them (though the absolute fastest require everyone else not to shoot the Archon or it gets messed up)

As far as the frame survivability goes, would have to know what frame and maybe some of the build.

Up until you need the tokens to do things and the turn ins for the son tokens are basically never the common predasite or vulp which are the ones that get knocked out (with the alternate route being to keep crafting up those basic ones and selling them which is even more monotonous)

Strips all the enemies armor, has the entire party and defense objectives take 0% damage, while applying a continous Gloom level slow to the enemies and popping out periodic energy orbs?

The funny thing about "Gara does Frost's job" is it unironically requires people to be bad at playing either frame. Frost's snowglobe is not his best ability (though nice when needed) and Gara's wall as a wall (and not a syngery bind with her 2) is probably her worst

Deimos Conservation/Son Token grind.

So we got an Infested planet, if you were ever curious. You can never avoid enemies on Deimos because Infested missions are in a pre-alarmed permanent state, and Deimos is no exception (unlike the ohter two which will spawn guys near you but you have to actually get seen to raise alarms).

Also its in a colour scheme where the highlight from the tranq rifle is basically invisible.

And two of the possible targets are miniscule sized creatures you can have trouble seeing if you're staying dead at the things.

You might want to do some serious malware/antivirus checks because Overwolf (and by proxy Alecaframe) got hit with some nasty self-propagating stuff recently. And that might be be whats doing whatever thats setting off the ban flag when you run it.
