Like Copperhead said.

I mean, it's never going to be SAFE to emerge. But right now the gas is just starting to spray AND people are still shooting, so I would definitely categorize it as 'unsafe'. You have two actions before I process who the gas drops (and Caduceus has one).

Papa, just to confirm, will the gas take effect at the end of this round (same as the injection) or will that be offset by another round?  I.e. Do we have to wait 3 rounds until the gas is inert or just two?  (Copperhead should be familiar with its behavior.)

Went back to the rule book, rather than depending on memory.

Neuro-stun is calculated based on the turn. The turn isn't over yet, so it hasn't been calculated. I will calculate it three turns, as the gas is dissipated. So everyone hanging out in the cloud will need to resist three times.

The rules also say to calculate it the turn after the turn it is deployed, so that would technically be 3 more rounds for most people. But for dramatic purpose, we can fast forward that a notch. At the end of the turn, we'll begin applying stun (same time as the narcojet, which is actually 'end of the combat turn').

Book says it disipates in two turns.  If it hits people 3 times, that would nearly kill most individuals (6S Stun x 3 = 8 physical).  So 2 turns of impact seems reasonable.  This doesn't seem like a confined enough space that would raise the impact higher.

To confirm my understanding:
Suprise phase - I jab with my needle, grenades go off

CT one - Drone runs away, goons flip table and fire, Khan runs towards his cache (hopefully taking deep breaths of gas as he goes).  At the end of this turn, needle and first CT of gas kick in

CT two - Everyone's feeling the +2 from the gas plus whatever damage they took but nobody has fallen down yet because the stun grenade + 1 CT of the gas can't put anyone over 9 boxes of stun.  At the end of the turn, the second CT of the gas kicks in, some of the people probably fall down and the gas goes innert

Is that accurate?

You're confusing rounds and turns.

1st round is your surprise; needle and grenades.
2nd round drone runs away, everyone is shouting and screaming (White Duck holds)
3rd round is whatever else happens next (White Duck has two actions)
End of turn, everyone in the gas cloud rolls to resist, Khan rolls to resist.

I know there are further actions this CT.  Anyhow, I'll presume I have things right from a CT perspective

Aside from what Duck did, I'm going to hold here until it's safe to go up.

Same.

So Duck's grabbing the grenades but not tossing any of them this CT.  (I'm totally fine with that, just confirming.)

Correct.

You guys should stay out of the smoke (and gas) for one more CT, but you should be relatively safe from attacks (and very hard to detect) by anyone inside the smoke if you're sneaking around the boundary and/or taking ranged attacks or tossing grenades at people inside.

Caduceus, if you've got any services left, speeding the two of you on your exit would be good.    The sooner the two of you can get out of that warehouse and out of the blast range, the better...

Hearth Spirits don't have Movement.  They do, however, have Accident, Concealment, Confusion, Guard, Materialization, and Search.  I was thinking I might just have it retrieve Copperhead's briefcase for us though, and/or maybe guard our exit as we escape.

Briefcase is right near your exit, so should be pretty easy for one of you to grab it on your way out.  Guarding or confusing is fine.

Copperhead's got a rating 5 skill in demolitions, so she should have a pretty good sense of how far you guys would need to get.  The force of the explosion is more likely to go up than down.  The utility coridor would be below the frost line, so you've got at least 4 feet, maybe more of dirt.  By the time you're 20 meters or so outside the walls of the warehouse, you should be more than fine.  Biggest risk would be flamable or toxic liquids or gases that flow down into the tunnel, which is why we made sure that your exit route was going to take you up-hill rather than down.  Could be some issues if there's flaming liquid that then generates smoke that rises up through the tunnel, but you guys both have sealed respirators and the van's only a minute or two away, so you ought to be ok.  Plus my drone is partly blocking the tunnel behind you and you guys are blocking things too, so hard for too much smoke to get up.

Caduceus wasn't seriously concerned about a tunnel collapse.  His mind was just wandering to worst-case scenarios and it was causing him to hustle a little faster.  Now if he had even thought about the possibility of flammable liquids, THAT probably would have scared him for real.

Copperhead definitely thinks about flamable liquids...

I thought that was Firefox's trait?

Firefox liked to make things burn.  Copperhead had the pleasure of molten metal pouring onto her face while jacked into a tank.  Very different attitudes towards fire...

That explains the facial scars.

Will Caduceus have enough time to try and recover from his stun damage?

Should have, y.  My guess is we'll grab some food, then head over to the apartment and rest a bit as we scope the place out.  Maybe have Noruas see if he can hack the security.  I can run a scan with my drone.  Then we send a couple of people in to check it out.  I'm happy to come with (pretty good at getting through security) or I can do overwatch.

I'm good backing him up onsite in case things get hairy.

My hope is we can tap into the apartment's security from an alley or something so he can sit beside or even in the van.  The guy's a runner, so I don't know his apartment's security would be super-hot.  We'll see I guess.

Unless you all are busting into the apartment like the Kool-Aid man, yeah, he should be able to heal up. However, everyone is running on little sleep, so some coffee would probably be good :P
