"Does anyone recognize that lake?" asks Angus

Marlyth doesn't recognize anything of significance in the murals.

Hamish replies to Angus.  "I wonder if it's Highstar Lake?"

<He was frozen before Waltarn died, so he's never been to the tomb.  You have though, and yiu saw a painting of a big lake there. Also there was one in one if Sylvenes hideouts.>

<since we have new players, and not all DMs run magic item discovery the same way, I'll just tell you:>

Walks feels the brooch has something peculiar about it, perhaps it is imbued with some kind of magic*. 

*it's a brooch of shielding so if you attune to it, you know what it is. Likewise if you've figured out what it is, you're attuned to it.

Tauzan discovers: It's a chime.

Lizardlyth will grab onto the metal chime and bite into the simple cord attached to the item so that the chime can be removed from the ceiling. Then she will climb down and move the chime towards Tauzan.

As Walks examines the brooch, the murky water begins to surge and froth, splashing and soaking any creature on the ground within 5 feet of such pools (just Walks). Creatures that succeed on a DC 14 Dexterity saving throw avoid getting liquid in their eyes and mouths. On a failed Dex save, make a DC14 Con save or be poisoned for 1 minutes.

A blaring shreik comes howling from a door that opens magically from a solid wall 30ft from the pool. 

From the water emerges a Skeletal Horror, who shambles onto shore splashing furiously as he attacks the nearest creature, (again that's Walks)

Roll initiative!

(I'll get a map up shortly, this space is larger than the cross section of the well, but no map is included in the module)

(Somehow I seemed to lose a post. Tauzan would have caught the chime and thanked Lizardlyth for cutting the cord.)

(Tauzan Initiative: 18)

Dex save 4

Con save 6

OOC: Good Gravy!

Walks, catches a face full of caustic liquid burning her eyes and making dizzy. She sees a monstrous form and struggles to defend herself.

NPC initiative:

Gorgon 18

Skeletal horror 6

Hamish 6

PCs

Tauzen 9

Walks 11

Angus 4

Marlyth 4

Calner 3

Tabaqui 20

From the ephemeral door emerges a figure with sickly pale skin, matte gray and green cabless of hair splayed wildly around her hideous face.  Behind her trails a long segmented serpentine tail.  Her eyes glow with a green light, casting dim light before her.  She bear long wicked claws and four sharp needle like teeth.  She carries an ornate longbow. On her ha d she wears a ring with a stone of bluish jade.

(I know DnD gorgon usually means the metal bull, but in this module, this character is known as a gorgon.)

Marlyth's Initiative: 19

Lizardlyth will strike at the Skeletal creature using her natural weapon and she makes a single claw attack while concealing Calner and Tauzan from the direct view of the Medusa-like creature.

Action: Attack: 13 Damage: 7

"Awww, hell!" Hamish bemoans, "avert your eyes!" he warns ad he holds a hand over his face.

The gorgon's howl subsides and in an unearthly voice she growls, "You've come to take from me?! I have nothing left to take!  Fools.  Now it is I who will take from you.  I will have your very souls, as my soul was rent from me."

She approaches the pool of water and near uts edge, pauses to call forth a swarm of snakes from the darkness itself.  She continues to slither into the water.  But she does not submerge. Rather, she slithers above the water.

The swarm of poisonous snakes advances toward Marlyth, in her reptilian form, slithering around her legs and snapping at her scaly hide.

26 for 8 piercing.  Marlyth, on a hit,, make a DC10 Con save or take 21 or half on success.

<still waiting on tabaquis initiative,  but we can retcon if it beats the gorgon's>

Walks and Tauzen (and maybe Tabaqui(?)) are up.

Crit snake bite damage 5

Tauzan runs over to stand to the right of Walks, drawing his khopesh from his side with his left hand.  He makes an unarmed strike against the Skeletal Horror with his right hand while slashing with the khopesh in his other hand.  Continuing to spin he makes another unarmed strike kicking with his foot.  He keeps the khopesh at ready to defend himself if necessary. 

Attack - Unarmed: 28 Damage: 10

Attack - Khopesh: 20 Damage: 9

Bonus Attack - Unarmed: 13 Damage: 11

Agile Parry - If you make an unarmed strike as part of the Attack action on your turn and are holding a kensei weapon, you gain a +2 bonus to AC until the start of your next turn, while the weapon is in your hand and you aren’t incapacitated. (Increases AC to 22)

Walks, grips her symbol and concentrates, bringing forth a blue/grey light that encompasses the party (except Marlyth - too far) with a Beacon of Hope.

Advantage on WIS Saves, Death Saves, and maximum healing for 1 minute.

Lizardlyth's Constitution Saving Throw x Poison Damage: 2

Marlyth absorbs most of the damage in her beast form and automatically reverts to her natural form.

(@Wile_E_Coyote, Lizardlyth was right beside Tauzan and she would have attacked the skeleton. Do I get to retcon her action for first round since the bite action is not applicable?)

(sorry)

Tabaqui initiative 18

Round 1

Tabaqui will loose an arrow at the Skeletal Horror.  He will also call out to the Gorgon, "We are not here to steal from you!  We are here seeking information on how to defeat the wizard who stole the stone!  We would return what is rightfully yours!"

Persuasion 14

Shortbow Attack: 23 Damage: 9 piercing + 16 sneak attack
