Small rocks bounce off Kroshav and Joe but more than anything it is hard to breathe with all the suffocating, blanketing dust in the air.

The rest of the part are able to take a step back into the tunnel they arrived in and are able to avoid the pelting of rocks but not the dust which quickly fills the space. Jaq and Cladmir can both just make out the glow of Lurn's shield right next to them, and quickly begin to find breathing the dust isn't great.

Mikram taps Lurn on the shoulder and leans in to say,

"Move back to where the air is clear and wait for the dust to settle. Shouldn't take more than a quarter hour."

((Okay, the area is heavily obscured now and breathing will require con saves should you choose to hangout in the dust cloud.

Can I get a perception check from Cladmir, Lurn and Jaq at disadvantage please.))

Groping in the obscuring dust, Kroshav grabs hold of Joe and if she doesn't object, will pick her up, hold his breath and close his eyes and quickly make his way towards Lurn and the others.

<Sword, tell me before I run into a wall, please?>

Lurn tries to pull some cloth from his clothing over his mouth and nose, starting to move away from the tunnel, "Out of the dust."

Perception: 15
Constitution if Lurn can't get out of the dust: 18

Kroshav snags Joe and starts moving to where he is pretty sure there was a wall. He hears,

<What is going on? Is it dark again? Wall!>

In his head just in time to avoid bouncing his snout on the wall. Feeling along the wall he starts tracing his way back towards the tunnel out, the problem being that there are a handful of  tunnels along the wall and, well, one hole in the wall feels pretty much the same as any other in the choking darkness. Sword provides some assistance in letting him know that she doesn't see anyone except Joe right now.

In the correct tunnel to the library Lurn turns and after hundred feet comes out of the worst of the dust. Ahead, on the edge of the light he sees one, then two then three sets of shiny black eyes. One on the floor, one on a wall and one on the ceiling. All three, very large spiders are motionless. Mikram coughs, hacks and spits then looks around and stiffens saying quietly,

"Ye see them? Aye see half dozen of them shouldn't have given the lizard meh pick."

<We dropped the tunnel, it's really dusty! Where's Lurn, he had his shield lit up...>

Kroshav risks squinting an eye open to try to get his bearings.

As the tunnel collapsed Cladmir quickly backed off away from the dust with Lurn.  Carefully he readied the hand crossbow before advancing into the unknown.

Not sure if this is still needed but here goes!  Perception:  2

Kroshav can see the wall in front of him with Joe's torch, but not much more. His eye quickly fills with grit even as he blinks.

Cladmir, blinking away some dust from his eyes, bumps into Lurn's back and can see only Mikram and the firbolg's dusty backs.

“Just keep goin’ down tha way we came.”  Joe takes out her compass from the cartographer mit and looks at it.  “By me guess ye should head…that way.”  Joe guides Kroshav’s head towards the entrance. Unless she hears about the spiders.  Then she will asvise against it.

Cartography: 11

also what does Ruby see in Lurn’s arms?

Lurn utters a few soft words, pressing a hand to his chest and casting Guidance, Lurn hopes the dust obscures the spider's vision as much as his and uses Disguise Self to make himself appear to be a drow before stepping forward, speaking in elven, "Little ones!  Dangers will be here soon, it is safest to move away much."

Animal Handling: 15 + 4 = ?

(Investigation DC18 to realise Lurn is disguised, per Disguise Self)

((I said way back when we encountered that giant centipede and its little ones that a priest where Lurn trained/studied kept a pet spider and he had no problem with it.  I'm sticking with it.  These sorts of spiders may have taken us all down before, but nothing can convince Lurn he can't talk things over with animals. :p ))

Joe can barely make out her compass as she pulls it out and it is quickly covered in the dust making reading it impossible, further her bag is now also filled with dust. Blinking away the grit she does figure that they do need to move back the direction she indicates another 50 feet or so but they'll need to move slowly along the wall so they don't miss their tunnel.

((Sound is muffled in the cloud so she can only really hear Kroshav, no one has said anything in a language she can understand about spiders anyhow.))

Lurn turns himself into a drow and steps forward, much to Mikram's dismay as his mount suddenly shrinks. The dwarf shouts a curse and scrambles for a new grip,

"What? Where'd Lurn...?"

Mikram investigation: 16

Mikram then growls and puts Lurn into a choke hold roaring,

"Ye aren't gonna get meh that easy again!"

Grapple with surprise: 16

Whether or not it underlines the threat or undermines the the effectiveness of the attempt to persuade the spiders remains unclear.

((Go ahead and roll again for disadvantage on the that persuasion attempt.))

((Disguise self is illusion with no physical change. 😉))

((Yep, but I figured he would still panic when what he was gripping disappeared, but I was going to roll him advantage on that investigation check and forgot. I found it amusing he was going to essentially 'choke' hold Lurn's upper chest.

7

And a 7 isn't gonna doing to do it.))

It was dark, it was dusty, and with the sound of crashing stone still ringing in his ear combined with the lingering dizziness Cladmir really has no idea what was happening.  He was pretty sure that at one point he bumped into Lurn and caught a sight of Mikram, but things just got confusing from there.  Still not really seeing or hearing anything clearly he heard what sounded like movements echoing from every direction and then some elven speech, and then Mikram yelling.  Not really sure what is happening he *attempted* to make himself invisible in the cloud of dust until he has a better handle of the situation.

Stealth: 22

Cladmir, seeing some weird crap happen as Lurn turns into drow (maybe was always a draw?) and Mikram freaks out a bit, takes a big step back into the dust.

I presume the +4 from Guidance doesn't change, so I'll just roll with a modifier of +9. 

Animal Handling Disadvantaged; 26

“Keep goin’ Kroshav, ye can do this.  Ah wish I had tha ability ta move tha air now.”

joe will briefly look through Ruby’s eyes

The spiders Lurn can see shift and wiggle their pedipalps first at Lurn, who is being hugged fiercely by Mikram without much effect, and then shifting to do the same to each other. After waiting for something from Lurn, and apparently not getting it, one moves forward relatively slowly. At 30 ft the spider stops and waves its palps again.

((Can I get an...insight from you on the spider. Just passive insight would let you know that it isn't acting aggressively.))

Not being able to use her own eyes to much effect Joe switches to Ruby's...and see's spiders. Big, hairy spiders on the floor, ceiling and walls in front of Lurn. One at the back skitters away but one comes closer to Lurn waving its disgustingness at Lurn.

Feeling along the wall Kroshav, with Sword and Joe's help, thinks they have the right way out and heads in with Joe in tow.

(what chaos, so quickly!)

Jaq blinks and squints when hit by the cloud of stony dust, trying to continue to see and be lookout.

17 Perception.

Once he notices how bad it is to breath the dust, he backs out to get to where it is clear.  

As he leaves he yells, "JOE....JOE...KROSHAV.   COME THIS WAY."

"THAR BE SPIDERS! DONNA GO CLOSER KROSHAV!" Joe shakes on Kroshav, clinging onto him tightly.
