(Misty Step would be a get out of jail free card, yes.  Vera, you can either attempt a strength check like Knox or try to hack through the webbing (which would be at disadvantage).  The webs were shot from around 30 feet away, but it would be a melee attack to attack them if that's what you're asking.)

Knox's robotic body easily tears through the webbing, surging to his full height (any movement afterwards?).

Wendigo lands a furious flurry of blows on one of the spiders, but his last attack doesn't quite get through the spider's thick hide.

Miles's vision blurs slightly from his rage, and his rolling pin just barely arcs over the spider's head.

Spider-Jhazaal rushes forward towards one of the spiders, but he doesn't seem to quite have the hang of this form yet, his jaws clacking shut on nothing.

(Vera and Paquinal are up)

(Gotcha thanks for the clarification)

Vera, sword already drawn, attempts to cut herself free from the spider webbing.  If she managed to succeed, she'll charge forward and attempt to get in melee range of one of the spiders.

Attack: 15 Damage: 10

Knox, having succeeded in freeing himself, closes the distance to their attackers, holding his shield up, ready to defend himself.

Vera hacks away at the webs surrounding her, and manages to free herself.  She charges towards one of the spiders.

Knox stomps towards them as well, readying himself for an oncoming assault.

(Paquinal is up)

(Sorry guys, I was out of town. Forgot to say something. Won't happen again)

Paquinal will use Misty Step to get out of the webbing, and then he will take Dodge, prepared for the spiders to attack again.

(You're fine.)

Eldeth hangs back a bit, and chucks an axe at one of the spiders.

Attack: 16 Damage: 7

Jimjar will fire off his shortbow at the most injured one (the one on Wendigo).

Attack: 11 Damage: 17

Sarith fires off his crossbow at the nearest spider.

Attack: 18 Damage: 5 (Con save if hit: 6, DC 12.  If failed by 5 or under goes unconscious.)

The spider in front of Knox falls unconscious, Sarith's drow poison coursing through its veins.  Jimjar's arrow skitters off the spider's back, but Eldeth puts down Wendigo's injured one.

The two remaining conscious spiders attack Vera and Miles.

Vs. Vera: 7 Damage: 8 piercing and a DC 11 Con saving throw or 12 poison damage, half on a success

Vs. Miles: 20 Damage: 5 piercing and a DC 11 Con saving throw or 16 poison damage, half on a success

Miles's spider manages to sink its fangs into his skin (Con save).

(Everyone is up, 1 spider on Miles and one on Vera.  One is unconscious but uninjured at Knox's feet.)

Miles:

A spider gets a lucky bite past Miles' defenses, trying to inject its poison into his bloodstream.

Constitution Save versus Poison (Advantage):  22

Miles retaliates with a frighteningly quick swing of his rolling pin, now properly mad!

Rolling Pin Attack:  Attack: 11 Damage: 13

Edit:  While raging, Miles takes half damage from everything except Psychic, so the piercing damage drops to 2 and the poison damage is halved twice to 4.

In his wolf-spider form, Jhazaal bites at another of the spiders.

Bite. Melee Weapon Attack: 15 to hit, reach 5 ft., one creature. Hit: 2 piercing damage, and the target must make a DC 11 Constitution saving throw, taking 7 (2d6) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.

Nimbly able to dodge out of the way of spider's second attack against her, Vera counters with a precision strike of her own. 

Attack: 23 Damage: 6 (Sneak Attack if it: 11)

(Unless otherwise told, I'm assuming that Vera has Sneak Attack on an enemy as there is either an ally within 5ft of her or her Swashbuckler ability to gain sneak attack 1-on-1 against someone is in effect).

Paquinal will fire three more magic missiles at the spider that attacked Vera

3 22

Con save: 20

Although Vera's spider manages to resist Spidey-Jhazaal's poison, the combined barrage of other attacks manages to put it down.  One conscious spider remains, on Miles.

Miles swings just as wildly once more, but doesn't manage to score a hit (you should have Reckless Attacks if you wish to use it).

(Wendigo is up)

Wendigo turns his attentions to the remaining spider, swinging his axes together in a downward arc.

Attack: 14 Damage: 4

Attack: 22 Damage: 6

Wendigo lands two more solid hits, driving his axes deep into the spider's carapace.

It retaliates, snapping its jaws at him.

Attack: 19 Damage: 7 and DC 11 Con save, 13 poison on a failure or half on a success

And sinks its fangs into him.  If the poison damage reduces you to 0 hit points, you are stable but poisoned and paralyzed for an hour.

Jimjar curses and fires at the one remaining one.

Attack: 7 Damage: 13

Eldeth retrieves her axe, and chucks it again.

Attack: 6 Damage: 6

Sarith shoots his crossbow.

Attack: 15 Damage: 7 (Con save on hit: 16, DC 12, fail by ≥5 then go unconscious)

Someone finally manages to shake off Sarith's drow poison, but the spider is still not looking so good (17 total damage).

(Everyone is up)

(In the future I'm going to start trying to have a spoiler that will keep track of how much damage each combatant has taken, both for me and for you.)

Miles:

Upset by his missed shots, Miles swings even harder, giving up defense for a strong offense (Reckless Attack).

Rolling Pin:  Attack: 19 Damage: 14

The spider crumples with a sickening fish of fluids, leaving only the unconscious one remaining.

Save: 4

Jhazaal bites at the remaining spider.

Bite. Melee Weapon Attack: 5 to hit, reach 5 ft., one creature. Hit: 5 piercing damage, and the target must make a DC 11 Constitution saving throw, taking 7 (2d6) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.

Paquinal thrusts a firebolt at the remaining spider (if it's still alive after Jhazaal's last attack)

Attack: 18 damage 4
