Stena switches to her shortsword as she watches the quaggoth get closer. Once he is within a short distance of her (10') she'll leap forward and attempt to knock him off the strand.

((Shove (athletics) attack with advantage?))

The width of the strand is such that she may not be able to knock him off, but may be able to knock him prone with a chance that he gets tangled in the event she isn't able to fully shove him.

 If you succeed, you either knock the target prone or push it 5 feet away from you.

((I've always thought this should scale by degree of failure, so we can try that here. I'll say you can have advantage on the shove if you pass a DC 11 Stealth check (with advantage) to beat it's Passive Perception of you darting forward and shoving it.))

Stealth: 17

It isn't alerted as Stena gets into shoving position.

Stena leaps and pushes the big hairy creature low, trying to send it over.

Athletics w/advantage: 16

Quaggoth opposed Athletics: 7

Stena barrels into the creature, and if they were on solid ground, she probably would have found herself running into a furry wall of muscle, but as the quaggoth steps back to reposition, its foot pokes through the web and it stumbles back, slewing around as it falls to the silk, its momentum carrying it over the edge, where it tugs on the trapped foot, which is slowly coming free. With a tearing of silk, the quaggoth plummets below, giving off a moaning howl as it falls. Stena sees it land in a swath of capture web, getting snarled and tangled as it struggles.

Stena gives a nod then turns, changes her form to match a (shortish) quaggoth and starts dashing through the lit up stretch.

Galingal, Kolose and Neth see a quaggoth move out of the darkness into the drow-lit area and begin charging towards their location. Plibbleburp gives a fishy yelp, and Jimjar fires a bolt at the approaching creature.

Attack: 12 Damage: 3

Galingal gets ready to attack with his rapier as soon as the quaggoth gets close (Attack: 6 Damage: 4  )

Stena keeps running until she is out of the light and disappears but does say loudly as she approaches,

"Not at meh ye idiot gnome. If yer shooting, shoot at the center of the black. The rest of ye keep moving."

Once invisible again she'll turn at sight at the center of the black sphere again.

Attack: 25 (25)

Damage (da): 4 (8)

"How the hell was I supposed to know!", Jimjar calls back, "What sphere?"

As Stena gets to the far side of the lit area, looking back, she can't see the crossing strand or the sphere of darkness.

"Ye should have just kept running."

She stares in the direction the Drow had been in.

"Ye see anything over there Jimjar? Aye only got one of the Drow and a quaggoth."

Jimjar pushes forward towards the edge of the drow light. 

"See three pale-skins and two of their beasts."

He steps back as a pair of bolts fall short, and the lights drift closer, but seem to be limited by casting range of the drow.

"Fair chance they saw me too."

Galingal looks around for their websurfing guides to ask them "Is there another pathway to get around the drow?"

"For sure, bruh. If they aren't following, I say we just leave 'em in out wake.", Yuk Yuk moves forward, away from the crossing strand.

Out in the darkness, there is a small glow of light as a torch is lit, revealing a drow and a quaggoth, maybe 150ft away.

"They are following. But maybe we can move fast enough."

((They are still on the crossing strand, ~20 ft up from the one you are on, so don't seem to be following just yet.))

"Whoa, dude. Rookie move, light'll draw the spiders and other stuff, but fire.. that'll burn webs right out from under you."

"Totally rookie."

Galingal looks at Stena, Neth and the others.

"Keep moving?" Galingal asks, already adjusting his pack to do just that.

Stena raises her bow,

"Aye'm pretty sure aye can hit them from here...but why would they light up a torch?"

She fires,

"Doesn't matter. He'll drop it when he dies."

 Attack: 14 Damage: 8

"Let's move."
