The Phandalin Chronicles

 Rekuberk will attempt to break out of the web and then move to ready an attack for when the spiders get closer.

Strength Check: 11

Krom seeing that Rekuberk is struggling to break out of the web will move next to him and try to pull him free.

Movement: 10ft to the right

Action: I will try to pull Rekuberk out Athletics 18

(If Rekuberk managed to free himself with his roll, Krom will still move 10ft to the right and take the dodge action trying to get the attention of the spiders by making noise with his shield)

Continuing to try and hide behind the wall Chill fires at the spider that is furthest north.

Stealth 29

Attack: 27 Damage: 25

Rekuburk tries to break free from the webbing that restrains him but isn't able to. While struggling to free himself Krom steps over and tears the webbing apart freeing him.

Chill, in an act of extreme marksmanship, sends a bolt right through the head of the spider killing it.

Rhogar is up

Rekuburk (71/71 +8),  Krom (51/51 +8),  Chill (39/39 +8), Rhogar (41/41+5), Chip (39/39), Kazri (58/58 +8),  Spiders

If Kazri can move before Rhogar and Chip's turn, she will move 10ft to the right, so she ends up in front of Master Krom. Otherwise she will move on her turn.

Seeing several lined up is enough to excite one Dragonborn into letting electricity dance upon his fangs. "No. Not quite enough room. New Plan! CHIP! For just a moment, get in front of Kazri, and release your breathe. I'll soften the ones in the back up for you." Without waiting on further word, Rhogar rushes just a few step off to the side and forward, and following a few uttered words in Draconic, sucked in a deep breathe.

What he unleashes in exhale is a divine born light splits mid-air into two separate bolts. One for each of the spiders in the far back.

Movement: Just 5ft north of Rekuberk's Postion.

Action: Cast (1st level)Divine Breathe, expending one Sorcery point for the Twinned Metamagic to attack the two undamaged Spiders in the back.
(Undamaged)Giant Spider #1 - Attack: 10 Damage: 12 of radiant.
(Undamaged)Giant Spider #2 -  Attack: 8 Damage: 14 of radiant.

(Of course I'd roll a 1... ugh... anyhow, using Favored by the Gods to add 4 to the attack roll against #1(3rd in line and just against the wall).

Rhogar sends a flash of light streaking towards the spiders.  It splits and heads for 2 spiders.  The first seemed destined to miss but the spider dodges the wrong way and gets hit by the blast of radiant energy.  The second spider though dodges the right way and the flash of light streaks past it.

Chip is up.  The easiest way to maintain order is to have Chip ready his action for when Kazri moves out of the way. 

Chip will move up closer next to his companions as smoke begins to billow from his nostrils. As soon as Kazri moves out of the way, he would quickly unleash a wall of flame towards the remaining spiders.

DC 12 dex save or take 7 fire damage, half on success.

Kazri will move out of the way and she will ready an action. If any spider crosses the web, blue line, she will attack.

Dex 10,  10,  8

The first spider in line, already burned, succumbed to the additional fire that racked its body.  The other 2 were able to dodge as best they could.

Rekuburk (71/71 +8),  Krom (51/51 +8),  Chill (39/39 +8), Rhogar (41/41+5), Chip (39/39), Kazri (58/58 +8),  Spiders (20, blind), (4), (0)

The closest blind spider moves forward and attacks Chip

Attack: 8 Damage: 11 + 12 poison damage on a failed save DC 11 Con save (8) , or half as much damage on a successful one.

The one behind it attacks Rekuburk

Attack: 8 Damage: 10 + 12 poison damage on a failed save DC 11 Con save (21) , or half as much damage on a successful one.

And the other attacks Kazri

Attack: 25 Damage: 10 + 5 poison damage on a failed save DC 11 Con save (26) , or half as much damage on a successful one.

Additionally Kazri can attack the spider that has attacked Rekuburk as her readied attack.

(OCC: I believe everyone, in this instance, gets to add +3 to their saving throw)

Kazri CON save: 12

Kazri was prepared for an eventual attack from the spiders, she is not able to strike the one that tries to hit Chip, but she strikes the one that tries attack Rekuburk.

Attack1: 14 Damage: 13

Attack2: 17 Damage: 11

(OCC: I am going to assume that when one attack due to their reaction, it is a normal attack. Meaning, Kazri gets to strike twice correct?)

As the second spider moves up to attack Rekuburk Kazri reacts and cuts the spider down leaving it dead.

Her attention is thus not on the third spider which rushes in and bites down on her leg spilling venom.

The first spiders attack against Chip misses completely.

Rekuburk is up

Attacks against the spider in front of Chip are made with advantage

Rekuburk (71/71 +8),  Krom (51/51 +8),  Chill (39/39 +8), Rhogar (41/41+8), Chip (39/39), Kazri (57/58),  Spiders (20, blind), (0)

Rekuberk will move up and attack the spider that just tried to hit chip, unleashing two slashes with his Greatsword.

Attack 1: Attack: 12 Damage: 14

Attack 2: Attack: 16 Damage: 9

Attack 2: Attack: 24 Damage: 8

Krom, if he can reach it without entering the area covered by the webs, will try to attack the spider that bited Kazri.

(If he can not reach the spider he will try to remove as much webs as possible with his hammer)

Blessed Warhammer : Attack: 19 Damage: 14

Rekuburk swings his heavy blade at the first spider and with a mighty cleave cuts its roasted and burned body nearly in half.  With a quick pivot he drives his blade into the body of the other spider.  Krom steps up and straddles the grating on the floor and with a swing of his hammer crushes the remaining spider, killing it also.

With the spiders now dead the fire in the corner of the room continues to consume the webbing. Soon the webbing has been burned enough that the SE corner of the room is cleared of webbing enough that you can walk through it easy enough.  Webbing still covers the SW corner of the room.
