Not assuming everyone is going to fight, she's waiting for any indication that the group is engaging rather than fleeing. If Thodek or Cailean engage with the spiders (melee), she'll attempt to flank the same spider to give one or both of them a bit of a leg up (hopefully negating the disadvantage from the fog cloud). That would also be a necessary maneuver for her to sneak attack.

Thodek moves about 10 feet to the north-west and looks up at Shoor, and snaps his fingers at him, "Remember me? BOO!" The last echoing into a mournful ringing noise.

Toll the Dead 5 vs DC 13 wis save.

After breaking free of the webs, Rian readies his sword. He moves towards one of the giant spiders, but as he can’t reach them, he instead uses his action to Dodge. 

End of Turn Dex Save (Adv. from Dodge): 20

Thodek: Wisdom Save: 21. 

“Oh you’ll regret that,” Shoor says as he seemingly shakes the sound off (Miss). 

Rian: You are able to make it 15 feet (Difficult terrain) towards the spiders at the edge of the webs, and do not get tripped up in the webs. 

Thodek, please make a strength or dexterity saving throw for the end of your turn. 

Voyage, Svyis, and Cailean are up! Then the NPCs will take their turn. 

Thodek str: 12

Thodek does not succumb to the stickiness of the webs, and is able to stay standing. 

Voyage will look up in the air and seeing Shoor floating there above the massive fog cloud she has created, she will push an Eldritch Blast right at that smug bugger's face.

Attack: 11 Damage: 9

She then moves 10 feet closer to where she saw Thodek, Syvis, and the deep gnomes fall onto the webs, remaining with the fog cloud the whole time.

DEX Save: 20

Seeing that the consensus seems to be taking out the flying drow first, Syvis takes a shot with her crossbow and then takes a step into the obscured area of the fog cloud.

Attack: 18 Damage: 5

Dex save: 6

Voyage: The eldritch blast rockets into Shoor’s side as he gives a grunt of pain (-17hp [Total: -23hp]).

Unfortunately though, as you try to pick up your feet to move again, they stick to the webs. You are now restrained, and must use your movement next round to break free. 

Syvis: Shoor seems to easily knock the bolt aside with his shield with a smile (Miss).

And as you slowly step into the fog, similarly to Voyage, you find yourself restrained in the webs. 

Cailean is up!

(Map is updated with those moves.)

I’ll go ahead and take Cailean’s move. @Vakarash may still be dealing with stuff, and this will help move it along. 

Cailean moves 15 feet towards the edge of the web and casts produce flame at the nearest giant spider

Attack: 9 Damage: 5

It flies into the nearest wall, missing the spider.

Dex Save: 9

Unfortunately, Cailean then find himself stuck in the webs, unable to move (Sorry!). 

NPCs are up! 

Buppido attempts to escape the webs.

Dex Save: 7

But he is unable to break free.

Ront spends half his movement to stand up, then using his action to dash towards the edge of the webs, preparing to battle the spider. 

Strength Save: 8

But suddenly finds himself stuck in the webs.

Derendil makes the same movements as Ront, dashing to reach the spider at the edge of the webs.

 Strength Save: 19

Unhindered by the webs, he is prepared to battle. 

Shuushar and Stool both attempt to escape the webs.

Shuushar: 11

Stool: 4

Shuushar is able to escape while Stool is not, but then seconds his action to help Stool escape from the webs. 

Strength Save: 18

Shuushar is able to do so unhindered by the webs. 

Eldeth gives a growl as she takes 2 shots with her crossbow at Shoor. 

Attack: 8 Damage: 4

Attack: 14 Damage: 6

Both shots go wide as she grunts with anger.

Dex Save: 4

The webs do not seem to affect her. 

The twins attempt to escape the webs.

21

And successfully get up before using their action to dash to the edge of the webs. 

Dex Save: 22

Seemingly unhindered by the webs.

Jimjar follows the lead of the twins by dashing all the way to engage the other spider.

Dex Save: 7 

Spry on his feet, he is able to not get stuck in the webs. 

 Shoor is up!

Shoor’s attention shifts to Eldeth as he raises his wand of viscid globs, taking a shot at her.

Attack: 24

A sticky glob strikes Eldeth in her chest and begins to spread and harden, encasing her as she falls onto the webs. Eldeth is now restrained.

 Giant Spider Initiative: 22

Initiative Order: Shoor, Thodek, Cailean, Syvis, Rian, Nicholas, Giant Spiders, NPCs, Voyage

 Thodek, Cailean, Syvis, Rian, and Nicholas are up!

 (Cailean, Syvis, and Nicholas are restrained)

(Map is updated on the doc.)

Thodek will move forward carefully, dodgeing attacks on his way to the water. (Full move North)

 Nicholas struggles and is finally able to break free of the webs. He quickly moves out of the Fog to catch his bearings, then uses his remaining movement to follow Thodek towards the water.

Syvis, mind racing and running scenarios and tactical maneuvers, decides to embrace the discomforting blindness of the cloud for the moment and triangulates the position of the spider she saw a moment ago before she ducked in for cover (on the left by Jimjar). She takes a deep, calming breath and squeezes the trigger, silently praying to Sehanine.

Attack: 14 Damage: 9

She listens intently for impact and stands motionless.

Rian, seeing that the webs slow him down too much, begins running towards the giant spider. He Dashes to double his movement. 

End of Round Strength: 10

Thodek and Nicholas: I need Dex or Strength Saves for the end of your turn.

Thodek, Rian, and Nicholas all run towards the edges of the webs, at the moment unhindered by the webs. 

Syvis: Somehow, your bolt strikes true as you hear the shriek of pain coming from the direction of the spider (-9hp). 

Cailean is up! (If it’s okay, I’ll give @Vakarash a little more time to make his move).

(Map is updated.)

Thodek str save 4

Voyage will attempt to free herself from the webbing.

Dex: 17

Having freed herself, she will aim another Eldritch Blast upwards at Shoor, hoping to end the Drow's concentration and sending the Drow crashing down to the web with the rest of them.

14

She will then try to steel herself to prevent herself from getting trapped again.

 OOC: I already made one in the original post right? I made a Strength save to break free then a Dex save for end of turn
