Progo looks at his bow confused "why you no kill spider?" He draws another arrow and trys again at the teal spider.(BA Steady Aim)

Attack: 19 Damage: 18 with sneak 

Tryncaryn neglected the bite with shield and killed the Teal spider plunging his feet in its head.
Rayce (thank you for standing up for your hero tom and also for doing it so polite. I did roll disadvantage for blue but i somehow did not for pink - good catch. second roll i made now was 11 to hit, hence it is a miss) might have seen like she was bit by the spider but it was just a part of her cloak that got bit and she is perfectly ok.
Progo feel free to change your target while we wait for goraseth an tharanaus turn /mind that blue and pink are getting some cover from tryn and rayce being in the line of shot/

(Progo will aim at the blue one instead)

(On the phone), Goraseth keeps attacking relentlessly the spiders (hit 14. Damage 11)

Tharanau feels a bit helpless in this mingle. He's also very aware of their future enemies, the hordes of undead they had heard roaming below. 'I will need to tune in to my magic more and practice some spells that can help in these sort of situations' Tharanau thinks to himself. 
He tries to shoot another spider (9 to hit for 4 dmg) with his magical ray.

Goraseth hits black spider again and the spider barely manages to not get killed.
Progo lands a devastating blow to blue spider, while Tharanaus magic does not hits this time.
Rayce can still act in this round.

Rayce lashes out at the nearest spider with sword and dagger

Main attack: 18 to hit and 10+3 hex+2djinn wrath = 15 damage

Off hand attack 22 to hit 2+4hex=6 damage

No movement 

Rayce follows up with shortsword to open further the wound that progo opened with his arrow, and opens it up wide, hence Blue spider dies with his insides flowing out. Before its empt carcas can fall on her she quickly strafes on the side to plunge a dagger to the side of pink spider. (i transferred second attack to nearest enemy since first one died. But since the other one was not hexed he gets only 2 dmg, unless you decide to forgo that attack and hex that one on this round)

Pink spider reacts swiftly with a bite on Rayce (attack16) dealing 6 piercing dmg and forcing an DC 11 constitution saving throw(fail: 3 poison dmg succes:1 poison dmg) /please also make concentration saving throw of DC 10 for maintaining hex/
Three spiders fighting Goraseth finally had some luck and the one being harrased by him managed to give something back and bites Goraseth (23 attack) dealing 4 piercing damage and forcing dc11 constitution saving throw (fail: 6 poison damage success: 3 poison damage) /please also make concentration saving throw of DC 10 for maintaining shield of faith/ 

Progo sees the pink spider having a bit more success getting through their defenses despite the multitude attackers. As Progo goes to draw his bow, out of the corner of his eye he catches the sight of a spider bite landing on Goraseth. Progo figures the other 3 on 1 spider will suffice as Goraseth defenses are starting to crack. Progo  spins and still holding his ground lunches a shot at the black spider:

Attack: 21 Damage: Unable to parse dice roll.

(Forgot to mention BA Steady Aim was Progo holding his ground so 0 movement)

Con save: 6 and 7. 

Goraseth did not see this one coming. He swears at himself, a begginer mistake that he pays now. He feel the poison getting in his flesh. For a second the pain is intense and he lose his concentration on his spell. The glimering shield surrunding him disapears. He thinks to himself "hmmm, that is not good". He then shouts to his friends "How are you doing guys ? I might need some help soon. Thiese spiders are tricky"

He then try to counter-attack the black spider but the poison makes him miss (Action Attack: Hit 8, damage 8)

Tharanau hears Goraseth's groans and runs towards him. (Case I3)

From there, he attacks one of the healthy spiders (red?) with witch bolt (to hit 21 for 5 dmg)

"I am going to help you, Goraseth! Leave the red spider to me!"

Tryn hears Goraseth yell and cringes but at the same time Rayce get caught by the spider's fangs. And everyone runs already to help Goraseth, Tryn decides to assist Rayce to take down this spider more quickly and, then, they could all together gang up on the remaining ones. He trudges through the spider webs and makes his way to the pinkish spider (H7>>G8>>F9>E9, each '>' represents 5 feet movement). There he directs a sidekick at the spider's torso (hit 11 for 6 damage), then ducks and lunges forward to drive his dagger into the spider (hit 8 for 5 damage).

Progo kills black spider, and arrow does not goes deep into it, but the force of shot tumbles spider dead body a little.
Goraseth seem to have depleted his luck with spiders and can not effectively attack them.
Tharanaus spell comes to aid and hits red spider with a lightning that shocks and catches to it and creates a link between spider and Tharanau.
Tryncaryn breaks trough the thick spider web and assaults pink spider, but being still sticky from all the web that accumulated on his body is not effective enough.

Rayce con save 15 and 14 so both passed!

She growls against  the pain of the bite and poison and lashed out again with sword and dagger.

To hit main 15: 5+3hex+2wrath= 10

To hit off hand 11:  4+3 hex =7 damage

If it happens to go down she will drop her weapons and take out her bow.

He still stands since the off-hand does not hit.
Pink spider lashes out at new attacker Tryncaryn (attack16) dealing 4 piercing dmg and forcing an DC 11 constitution saving throw(fail: 12 poison dmg succes:6 poison dmg) but is greatly distracted by pretty fly and bites the air close to tryncaryns head. (Tryn Shielded the attack)
Red and yellow spiders are fighting Goraseth but they do not harm him this round.

Tryncaryn saw the bite coming and conjured an iridescent giant fly to distract the spider. For his retribution however, he waits if Rayce wants to settle her score first.

Tharanau activates his lightning arc again and the red spider gets singed a second time (dmg 6). "You're holding the ground well, Seth! Keep going!"

Goraseth tires again to finish off one of the spider (hit 17,  damage 4)

"Die you beast!" Rayce shouts at the giant disgusting spider in front of her.

She attacks with both weapons again

17 to hit and 5+2+2=9 damage

Natural 1 on second attack.
