Triäsa's bolt flies harmlessly into the fog cloud adding to the confusion from the Anchorite and it's companions as it feels the force. You are able to find 3/4 cover behind a large tree as you cast. The soft dirt of the forest below is a welcome feeling from the stone and dirt floor of what seems like the endless prison. Out the corner of your eye you spot a slow fluid movement. 

Triäsa roll perception

You also still have Maxx's Turn

Pardot sprints forward as fast as his little legs will carry him. His halfling companion ducks out of the cavern and is able to make it about halfway down the rocky steps toward the forest floor.

Dandelion quickly gets behind Gehir who is facing the portal, leaning menacingly down at the kobold. Gehir never see it coming. The mummified cat launches themselves into the air teeth and claws bared wide. Even through the fog cloud you can see brilliant, blinding green-blue light. Gehir lets out a horrific howl that interrupts the chanting and there is a terrible moment of silence before a huge shockwave rocks the entire cavern nearly knocking each of you over. Through the fog you can't tell what has happened but you can feel the roof and the walls cavern tremble and shake. Bits and pieces of dirt and stone begin to fall at your feet.

Malisons 1 and 4 hold an action.

Anchorite 1 has had enough of whatever is happening. It again hisses in a foul language and casts Dispel Magic on the fog cloud. As abruptly as it started the fog and your cover is gone. In the moment of clarity you also see the portal with Yig, Gehir and Dandelion are also gone.

"What have you done?! Where is Yig? Where is Gehir?!" Calls out Anchorite 2. "Die! All of you!"

Now that the fog is gone it is extremely clear that the cave and temple is collapsing around you. 

X coordinate: 1 Y coordinate: 14 Damage from falling debris: 11

To be continued...

A large piece of rubble crashes down from the roof onto L1 just as Pardot steps into M1.

Now that the fog is gone, the ritual apparently stopped the lizardfolk let loose a their fury.

PB2 fires a readied shortbow at Gunnar

Attack: 9 Damage: 3 + 3 poison

The Priest hisses at Cathbad who is standing right in front of her and stabs wildly with her dagger

Attack 13 Damage: 7 + DC15 Con Save  with 9 poison on a fail. Half damage on a success.

Malison 1 and 4 both draw their longbows and fire quickly at Daventry

Attack: 17 Damage: 7 + 6

Attack: 17 Damage: 3 + 11

Seeing Ludolf so close to escape PB4 fires a short bow in his direction

Attack: 19 Damage: 7 + 8 poison

PB1 moves 5feet to the east and engages Daventry swinging her scimitar

Attack: 16 Damage: 6 

For simplicity I am going to move Malison 2 down in initiative after Daventry.

The sh*t is hitting the proverbial fan but you all are good I am sure!

Ludolf and Daventry are up! 

(Triäsa Perception: 23)

Following Triäsa, Ludolf would dash and the call upon his eldritch powers to follow the young half-elven bard down into the forest.
(Finishing up last rounds held action, Lud is moving exactly as Tri, using Misty Step to follow her down.)

Ludolf too seeks cover by Triäsa, then turning to try to cover the escape of the others, using his eldritch powers to drive a spike of psychic energy through the mind of any enemy he can see up at the temple entrance.
(Mind Sliver, Int save 16 or Psychic: 7 and - 2 to next save)

The burst of blue-green magic seems to wash over Daventry, shimmering across her. She locks her eyes at the portal a moment, almost stunned, as if she's not focused on this world but something else, something beyond. Her grip on her blade tightens, and she doesn't even flinch as she takes a poison-laced arrow to the shoulder, the other attacks going wide.

Con Save: 23

She nods. Perhaps at nothing, perhaps at acceptance of her fate, it's hard to tell in the chaos of the melee. But it is a resolute nod, one of conviction.

She shouts. "I swear to you, Nodens, that I awaken! I swear the path of discovery, that I might know my foe! I swear the path of prudence, that I might see all paths before me and choose wisely! I swear the path of courage, that I might push back the encroaching darkness with no reservation in my heart!"

She looks at the rest of her friends as they make their escape. She speaks more quietly, sparing a glance to the outside world. "I swear to find wonder in this world and all others, as they are beautiful and worth saving." 

She glares at the priestess that attacked her, and shouts at the rest of her newfound companions. "Gunnar and I have the line! Get going!"

She raises her shield, ready to block, and nods to Gunnar.

Action: Dodge (shield's up!)

Move: K2

Reaction: Sentinel Ready!

 Gunnar nods, and moves in a position to block any snake from getting past him and Daventry so that Cathbad, Shorty, Maxx, and Pardot can get clear.

Action: Dodge (shield's up!)

Move: M2

Reaction: Protection (Pardot or any other adjacent ally, first attack on them has disadvantage)

House Keeping Post

Crit Damage at Daventry 11 + 1

Cathbad Con Save: 14

Since Ludolf misty stepped on his bonus action the attack would target someone else. Let's fire at Pardot so that's a miss

Int Save from Anchorite 1: 22

Daventry's movement is first triggering an AoO from the PB

Attack: 22 Damage: 6

Gunnar's movement will trigger an AoO from the priest (Viper and I discussed the path)

Priest Attack: 23 Damage: 3 DC15 Con Save on hit or 13

Gunnar Con Save if needed: 21

The priest's attack will trigger Daventry's sentinel attack and the priest immediately regret her choices in life as the crit and divine smite go off.

Will hold for turns from Maxx and Cathbad!

DA for AoO on Daventry due to dodge: 13

   Updated Map

• 

Under the cover of the fog Maxx sprints down the steps 15 feet from the edge of the forest. From there she watches as the sounds of battle ring out. Cathbad bleeding heavily and out of breath sighs, "Maybe we do die here he mutters." He bobs and weaves disengaging and running as far as he can down the steps. 

Malison fires his longbow at Pardot triggering Gunnars' protection

Attack: 7 Damage: 10 piercing + 2 Poison

Pureblood 5 relies on what she does best and fires her bow as well. This one at Daventry

Attack:  21 Damage: 2 + 10 Poison

The Anchorite sees Cathbad nimbly dodge past him and looks down the stone steps and realizes there are two escapees. (He is oblivious to Ludolf and Tri's existance). He turns and looks down the stairs the strange arachnoid appendages stand straight up on it's back as he fires Web's at Maxx. Targeting it so that the webbing reaches just to the tree line. (I guess I'll need that map...)

DC for Web is 14

Malison 3 charges forward to M3 with rage and tries to bite through Gunnar's armor...

Attack 20 Damage: 4 + 5 Poison

At the top of the round the roof of the temple continues to crumble. It does not look like it can hold much longer. Two more large pieces of rock fall from the 30 foot ceiling.

 Rock 1: X coordinate: 6 Y coordinate: 4 Damage from falling debris: 6

Rock 2: X coordinate: 5 Y coordinate: 6 Damage from falling debris: 9

To be continued....

Gunnar yells out as the sharp teeth of the Malison find a soft spot in his armor. The second rock fall harmlessly out side of the temple while the first comes crashing down hard in square H7.

PB2 keeps her distance relying on her deadly shortbow firing again at Daventry

Attack: 10 Damage 2 + 5 Poison

The priest shifts around Daventry to J1 to keep and eye on the escapee. Seeing Maxx so close to the tree pulls her head back and spits a magic ball of acid at the tiefling. 

Attack: 19 Damage: 6 Acid and another 7 at the start of her turn unless someone removes the acid.

Forgot Dav and Gunnar are dodging so here is a second roll for both the attacks at them

Gunnar 6 Daventry: 11

Triäsa and Maxx (15)/Pardot (14) and Shorty are up

The nimble paladins focusing on defense fend off their attackers. Unfortunately Maxx takes the full force of the acid arrows. (I rolled a DA roll in the campaign log for ranged attack while engaged in melee. It was a 16+7 so still a hit.)

Updated Combat Tracker:

• • PB2 
  • Priest (40)
  • Triäsa (Unseen, 2/3 Cover) and Maxx (31 + 7 unless someone takes the acid off, I highly suggest someone does something about acid before her turn... Web)
  • Pardot (14) and Shorty
  • Dandelion (4)
  • Malison 4
  • Malison 1
  • Anchorite 1 (10 -3 to next save)

  • Daventry (28; Dodge) and Gunnar (Dodging)
  • Malison 2
  • PB 5
  • Anchorite 2
  • Malison 3

Maps:

(My understanding is that where Triäsa is located is 60 ft from the row 1 on the other map.  So the priest cast the acid spell is within 60 ft but the Anchorite casting Web is not? That is my presumption as I'd have preferred to stop the web first.) 

As the Priest starts to cast the acid spell targeting Maxx, Triäsa casts Counterspell to interrupt the process. (Uses her Reaction.) 

"We have to get deeper into the forest. I can see something. I know it's the way," she tells Ludolf.  She again casts Force Bolt at her target then moves another 30 ft into the forest, following the motion she saw.  If possible she will try to keep cover amongst the trees. 

(If she can see the Anchorite that cast Web, she attacks that target. Otherwise she will attack the Priest.)

(Triäsa Force Bolt Attack: 23 Damage: 13)

Maxx (never having been hit by the acid, I think) will try to break free of the webs. (STR Save: 6)

If she does get free she will hurry 60 ft. into the wood. (Movement plus Dash) 

Maxx looks up as the acid starts to form and fly thourgh the air, Ah my sweet release she thinks as she closes her eyes. At the last moments Triäsa's magic interrupts the weave and the poof the acid out of existence. A warm refreshing breeze washes over Maxx who opens her eyes and she begins to struggle against the webs, unfortunately she is not able to get free.

(You can have advantage on your force bolt. The baddies have no idea you all are there in the woods.)

Pardot/Cathbad are up

Cathbad rushes down the steps. "Hurry up Shorty, make for the forest and run away from this place." He calls out to the halfling, then coming up to Maxx, trying to help her free. 

I got confused with initiative. But we will take that as Cathbad's turn! I really need to murder some (N)PCs.....

Pardot and Shorty are up!

(Added advantage roll on Force Bolt: 22)

Finding himself one of the last in the snake dungeon, Pardot knows that he needs to move his little legs as quickly as possible in order to survive. Dashing away, he only hopes to be able to dodge any attacks coming at him. Shorty does the same, though from a bit further on, avoiding the web and just trying to dash towards the wood.

"Foolish child." Anchorite 2 calls out as Pardot tries to make his escape as it lashes out with it's claws

AoO: 13 Damage: 13

Maxx struggles against the sticky goo and is unable to break free. Thankfully Cathbad rushes to the edge of the webbing, lights and tosses a torch at her feet. The flames lick at her feet but her tiefling nature resist most of the damage. She almost smiles at Cathbad as she prepares to leap into his arms on her next turn.

Fire: 4 (She will resist half damage)

Triäsa's bolt of force flies through air and strikes Anchorite 2 along one of it's appendages drawing black blood. 

Malison's 1 and 4 keep their distance from the paladins and rely on their bows to try and take down the large blonde man.

@Gunnar

Attack 1: 9 Damage: 9 + 5 Poison

Attack 2: 5 Damage: 8 + 9 Poison

Anchorite 1 watches as Pardot flees. It's deformed body smiles... as the creature pixelates and disappears only to reappear at the bottom of the steps as he casts Misty Step, then slowly it crawls on two legs to Pardot and swings it's claws.

Attack: 10 Damage: 7

PB4 and PB1 decide to target Daventry as the Malison's had fired at Gunnar.

Attack 1: 4 Damage: 7 + 8

Attack 2: 6 Damage: 6 + 6
