Pip Dex Save Vs Web(DC 15): 5.

Gundren H. Crossbow Shot VS Necro Spider(AC 15) - Attack: 13 Damage: 2 piercing.

Gundren Dex Save Vs Web(DC 15): 10.

Web Recharge: 5.

Necro Spider Bite Vs Anton(AC 20) - Attack: 25 Damage: 14 piercing. If hit, make a Constitution Save(DC 12) to take  half of 2 Necrotic Damage.

Ordrin rushes forth to aid his compatriots, and bids Gundren to do the same. Even the webbing can only halt him for a moment or so before he ultimately breaks through and leave the mass. Now he stood to the side of a corruption of nature, warhammer in hand, and spirit full of determination to right the wrongness of it all!

Pip nearly hesitates to act, but is able to muster the courage to brave doom to ensure the safety of his own. Every step beyond the doors are one the gnome has to fight for until it is just too much. It is also just enough to reach the fallen halfling; still wrapped up, at least for the most part in Giant Spider Webbing. In seconds the magic of the ointment does its work, bringing Riris back to consciousness. 

??? remains a mystery for now.

Gundren nodded sharply to Ordrin during the brief exchange, and was quick to follow suit. However, before letting the webbing become a problem, he looses one more bolt for the sole remaining spider -- if it can truly be called that -- before running after Ordrin hoping to use the path his fellow dwarf roughed up in his wake. Such was the plan, but one too many missteps leads to him look like a tangled up marionette. An angry tangled up marionette. 

Necro Spider begins again to drool that black, viscous substances again from its mandibles. Yet in stead of loosing it, it goes for the bite, brushing aside Charlotte's meager attempts to ward it off from Anton before at least one of its great fangs pierces the man's collarbone, and inject some of the vile substance right into his veins. 

Anton, Riris, and Mixum/Charlotte are now up! If you would start your turn within 5ft of the Necro Spider, go ahead and roll the 2d4 Necrotic Damage for the start of your turns again. 

Charlotte and Riris must also make a Dex Save at the start of their turn from Web. Riris being with disadvantage, unless the Giant Spider Webbing is removed prior to then.

Note: Bite damage is reduced by 3 from Heavy Armor Master feat.

CON save vs extra necrotic: 23

Necrotic damage from spider aura: 4

Anton struggles to pull himself free from the webbing (STR check: 6) but is unable to do so.

With a surge of determination he tries again! 23

and this time manages to pull himself out and circle around the terrible creature (to G8, or whatever the space is to its northeast), and focuses his will on fighting through the pain (Second Wind: 11 healing)

Dex Save: 6

Necrotic damage: 4

As Riris's eyes open, feeling Pip's Restorative Ointment absorbing into her skin, she makes a move to stand up - forgetting about the web -, and tangling herself on even more web from the precarious choice of moving. Now very stuck, Riris is not planning on fighting it because she'd be very likely to stay stuck. So, forcing her way to her lute, she plays it one more time, this time using her own source of magic as she focuses her eyes on one spot behind the spider, but far enough to not hit any of her allies.

Casting Shatter centered on F7. DC 13 Constitution Save or any creature within range takes 19 thunder damage.

(Would rather target Nezzenar, but I can't see him since it's too dark in this room.)

Mixum tosses a glitter bomb halfway between the spider and Nezzanar. (Faerie Fire) Dex 13 save.

Charlotte makes an effort to free itself from the webbing.

Necrotic 

To All: Finally free again! At this point, I am going to assume Mixum targets the spider itself to give others a better chance, and let's Charlotte stay on Auto-Pilot for now.

Also, to not negate his roll, I'll be taking the 1st 4 dice in the sequence that he rolled and distribute it.

N. Spider Con Save vs Riris(DC 13): 12.

Turn Start Damage:
Mixum: 4.
Charlotette: 2.

Necro Spider Dex Save vs Mixum(DC 13): 14.

Nezzenar Ray of Sickness at 2nd level vs Anto(AC 20) - Attack: 21 Damage: 17 poison. If hit, make a Con Save(DC 14) or be poisoned until the start of Nezzenar's next turn.

 Anton huffs and puffs, and in eventually in a surge of adrenaline straight up flexes his way out of the webbing. He soon takes the tactical approach of excavating himself from the seeming endless curtain of webs to stand to the north of the spider, spear still in hand, and second breath captured to better withstand what was to come. 

Riris instinctive struggling to at least avoid getting further tangled up on results in the opposite happening. So, abandoning any further thought of freedom, awkwardly strums a few notes on the lute, magically detonating the air and empty space just beyond it with enough destructive force nearly knock it off all eight of its legs! As it screeches in pain, a few chitinous plating cracks and threatens to fall off. Not knowing who or what was responsible for the damage, it more frantically whips around screeching and clacking its mandibles angrily at everyone within range of it.

Mixum changes tactics and breaks out the Glitterbomb to help put the fight more so in the group's favor. Unfortunately, whatever vapors or shadows or whatever it was leaking off of it appeared to devour whatever bits of the mixture that it cannot quite avoid. Charlotte meanwhile tries to avoid getting trapped in the webbing, but finds herself bound in it. (edited)

Nezzenar chuckles darkly. "You all are so... so... SPIRITED! I'm starting to see why some of those lesser houses make a habit of raiding the surface for more choice servants from time to time." He says just before another ray of toxic destruction comes flying out of the darkness. This one aimed for Anton. Even if it should hit its mark or not, Nezzenar continues on nonchalantly saying, "Hm~ It'll be awful waste if the experiments go wrong you know. So how about this... If you surrender now, and start acting more civil, perhaps we can make a trade. Your lives and the life of that worthless dwarf in exchange for helping me with a little... side venture here. What do you all say?" He asks, shifting from one place to another.

Pip and Ordrin are now up! Since now within 5ft of the Necro Spider from the start, Ordrin may go ahead and roll the 2d4 necrotic damage at the start.

Necrotic damage: 5

Ordrin circles the spider (to avoid OA) to stand next to Anton (in H8) and swings his warhammer at the thoroughly disgusting carapace. Then he sends a silent plea to Sharindlar for more strength in aiding his allies (Harness Divine Power).

Attack: 13 Damage: 4

Pip, having gotten himself stuck in the webbing, tries to extract himself and move 5 feet south and out of the sticky mess.

Dex 17

Squirming his way out he then weaves a quick cantrip Frostbite to hopefully slow the spider to allow the stronger members of the party finish it off.  

CON 14 save or 2 cold damage.

Necro Spider's Con Save Vs Belpip(DC 14): 7.

Gundren's Strength Check vs Web(DC 15): 15.

Gundren's War Pick Vs Necro Spider(AC 15): Attack: 21 Damage: 6 piercing.

See below post by me.

Ordrin maneuvers about the beast to join Anton's side. His hammering however rebounds off the shell as surely as Anton's spear. Set back but determined, a silent plea to the goddess goes out, asking for strength to aid not himself, but those that fight along with him in this righteous assault upon an abomination of life. Although he hears no answer in turn, a warm spreads from holy symbol to the rest of his body, returning at least some of the strength necessary to channel the magic of the goddess.

Pip thinks to fight his way out of the webs, so that he can better support his team. But when even the smallest efforts already felt like a momentous task as is, he turns towards making the slight gestures necessary to chill it to its core.

??? remains a mystery for now.

Gundren tries his best to fight free of his sticky prison, and eventually pulls far enough free to stumble out of the mess[G11]. "Outta mae way ya foul creature!" He yells, pulling War Pick at his hip free, and striking the creature's back legs in a Surge of Energy[Action Surge Expended]. Its shrill cries after only appearing to exhilarate the dwarf more.

Despite all black blood was now beginning to ooze out between the cracks in chitin, the Necro Spider looked about frantically not for escape, but with malevolent intent... (1)...

It is afterwards that many of its eyes settle upon Anton. He has but moments to realize and try to mount some sort of defense, before the spider lunges out at him. Unfortunately, even with Belpip's magic lingering in its system, it latches on tight, injecting Anton with more of its corrupted poisons before the man eventually manages to push it off.

Anton, Riris, and Mixum/Charlotte are now up! If you would start your turn within 5ft of the Necro Spider, go ahead and roll the 2d4 Necrotic Damage for the start of your turns again.

Necrotic dmg: 3

Wincing at the flesh-rending pain of the spider's evil aura, Anton cautiously circles around to the southeast of the spider, standing next to Gundren (H11), and resumes his assault, stabbing his spear at the creature and attempting to knock it off its feet.

Attack: 15 Damage: 14

(Using Trip Attack if hits: DC 14 STR save or fall prone)

He follows up with the blunt end of his spear, trying to drive it back (using Crusher) and frighten it so it hesitates to move closer (Menacing Attack: DC 14 WIS save or be frightened of Anton until the end of Anton's next turn)

Superiority die dmg for menacing: 5

Attack: 9 Damage: 10

(2nd attack die if it is prone: 26)

Edit: I screwed that up by accidentally adding the menacing damage before the 2nd attack roll, sorry... I'm getting a 403 error when I try to revert it, but the 2nd attack was an 18 to hit and 11 damage originally and the menacing damage was 4.

Necro Spider Bite Vs Anton(AC 20) - Attack: 25 Damage: 8 piercing. If hit, make a Constitution Save(DC 12) to take  half of 9 Necrotic Damage.

Had to put it here after putting that d3 roll in the wrong place.

OoC: How is it that everything seems to hit Anton despite his armor? Oof, _and_ disadvantage?? Must be his magnetic personality or something

CON save: 23

Mixum looks around through the webbing and determines that Nezzanar is responsible for the webbing. He takes aim with his hand bow and fires.

(At the start of Riris's turn, the necro spider is dead, so no damage taken.)

Not having to worry about the spider near her anymore, Riris decides to help without moving in any way she can. Making light gestures with her still stuck hand and voicing some arcane words under her breath, a translucent pink spectral hand appears right over where the brightly-lit copper piece was.

Then, Riris tries to speak out some more arcane words to see if she can keep Anton's fighting spirit up to be able to deal with the drow's next attacks.

Nezzenar Reaction: Cast Shield starting from Mixum's 1st Attack.

Nezzenar Scorching Ray at 3rd level.

1st Ray vs Anton(AC 20) - Attack: 26 Damage: 2 fire.
2nd Ray vs Riris(AC 15) - Attack: 7 Damage: 8 fire.
3rd Ray  vs Mixum(AC 17) - Attack: 26 Damage: 16 fire. 
4th Ray  vs Mixum(AC 17) - Attack: 22 Damage: 6 fire. 

 Anton endures and even fights through the pain of just being near the creature for at least one final assault. He circles around it to stand beside Gundren, and after trying to take its legs out from under it in briefly shiskabobing two with the point of his spear. As it stumbles about lopsided and hissing in pain, a sharp WHACK of the butt of the spear snuffs out both spirit and life in one guy, bowling the creature onto its back. As the last of its flailing eventually ceases with it legs curling up on itself, and the strange vapors or aura finally dissipating in death, Anton walks with more confidence back to his starting position knowing only one foe remained now. 

Riris needs to squirm a little to see the angles. But following a few arcane words and subtle gestures, she manages to conjure pink spectral hand near enough to the coin to at least pick it up. Looking up after, her next words are laced with a powerful magic, as Anton soon feels some wounds mend, and fighting spirit most of all reinvigorated to a degree!

Mixum abandons thoughts of freedom and fire a few bolts at Nezzenar. But not only do the webbings make it difficult to even line up the shot. Against all odds the Marked gnome gets just the right angle as to crack off a few shots at Nezzenar. Yet, just as the surprisingly accurate bolts come near, the drow snaps his free hand fingers in a sharp Z-formation and conjures a spectral barrier to deflect the bolts.

Meanwhile, Charlotte stays on the defensive.

Nezzenar slams the butt of his staff on the ground, and to those with darkvision, they can see him scowling as well. "You despicable, disgusting, and degenerate little cretins. So be it. I tried to be civil about all this, and yet you cannot even be bother to respond except with more violence. Unbelievable! But fine. If that is the way you wish to play it, then who am I to stand in the way of such ignorant creatures so determined to die." He said caustically. 

Moments later, the darkness is again lit up once more. Although this time by a series of red hot rays that burn anyone or thing they make contact with. Which for Anton and Riris, this spelled their doom as at least two of the rays are just enough to put them down. Riris is left in even more dire straits as the webbing at least in her immediate vicinity also catches flame. While she may be freed soon it would not be without a cost...

Pip and Ordrin are now up!

OoC: Seriously, Anton is somehow unmissable. In case anybody missed it, he is unconscious after that scorching ray.

OoC: So is Riris. Awake long enough to shatter the spider and cast mage hand. No more than that.
