If it doesn't come at them (this painted looking rat that still gave a hint of movement), Galingal will point it out again and suggest "Follow the goblins path but keep an eye on it."

He then moves back to the ledge to see what's taking so long, and to retrieve the rope. When he sees Kolose dangling in the air he just shakes his head.

"Why is he climbing down and not using the rope?" Galingal asks. "Hurry up. Might be rodent in the tunnel. Maybe not."

Lia and Neth nod as Galingal returns to see what's taking so long. 

Above Stena, the cleric can see the silken strand bobbing before going still... Then bobbing about again, then still... Perhaps something took note of Lia's cry...

 ((Does Stena notice the rope moving around then stopping as well?))

((Sorry, not the rope, but the web above her. If he focus is down on Kolose, she wouldn't but if she's looking around after Lia's scream and Kolose's fall, she would.))

((She was looking around after the scream, especially since Kolose didn't scream or make much noise himself.

Perception: 6))

Stena's attention isn't on the surroundings, but she notes Galingal looking up past her, and looking over her shoulder, sees the webbing bobbing then going still.

"What is i---", Jimjar starts to ask her, "Yeah, we should get going... do I wait for the old man, or use the rope now?"

Kolose's fingers are starting to burn as he clings to the side of the rock, twenty feet up.

Stena fades to invisibility (presuming she is in the dark) involuntarily and hisses to Jimjar,

"Down now, use the rope. Fast."

Does Petmailer hear any of this activity behind him?  

Perception : 8

Petmailer isn't initially aware of Galingal and Stena noticing the web moving, his focus being a bit more on the elderly wizard dangling from the rock, and then the deep gnome clambering over the side on Stena's hurried orders... before his hands slip on the rope and he careens towards the dangling Kolose.

Jimjar attempts to push himself off a bit to spare the wizard... 

DEX Save: 6

But it's not enough, they collide and both wizard and gnome plummet towards Petmailer.

((Attempting to catch one, both or neither?))

Stena watches the chaos from above.

Stena sends with her hard gaze that they'd better damn well be quiet when they break their spines.

Her eyes twitch back up to the webbing after whatever happens to see the reaction, if any, from above.

Kolose, torn between trying to lunge for the rope or simply dropping, would probably have to tried to reach for the rope... But things go south long before that happens. 

Petmailer rushes back and attempts to catch both, wizard and gnome, doing so as carefully as he can.  “What is happening…with..you..people..”

Athletics check : 21

Galingal watches the chaotic mess of a descent this has turned in to. He almost considers the positives of a smaller group if Petmailer had not made his catch but both the old man and Jimjar have proven capable in other ways. He moves quickly to pull the duo in so that they don't pull Petmailer off the ledge now too.

He readies himself to provide cover for Stena if she should need it when she begins her climb down. Assuming it's a spider in the webbing, it will need to be dissuaded from coming closer.

The selfless drow hurls himself under the falling party members, and does a passable impression of a mattress, the tangle of gnome and old man landing on him painfully.

((Kolose takes 3 damage, Jimjar takes 6, and Petmailer takes 9.))

Stena is alone at the top, keeping an eye on the web above, when the crackling snap of Neth's magical attack rumbles out of the tunnel!

 "It moved! Uhh... it's not a rat!", he calls in a low hiss. "We'll be fine though!"
