((It was Thunderwave. Don't know why Dndbeyond keeps doing this. Rolled total of 17 Thunder damage. 19 to hit and 8 damage with scimitar if AOO goes through. Rolling and posting on phone.))

Danica would shout out to the Seekers: "Attack the snakes! The Yuan-Ti!"

Meili rushed to the sound of battle. Thinking on the foot began a norm by now and she was absorbing the information on the go. The first "snake" that came into view was the first she attacked:

Movement: normal 40ft+Dash for 1 ki and BA

Attack (the Yuan-Ti archer by Danica): Sword Attack: 19 Damage: 5
                                                                                              9 Damage: 4

If any attack hit (and the Yuan-Ti is still alive) another ki point for Stunning Strike (Constitution saving throw 14 or be stunned until the end of your next turn)

Nalomanterys strides 30 ft toward the game trail and quickly assesses the situation. He sees that his allies are starting in on these reptilian people, so he attempts to disable some of them on the other side of the path.

((I'm having a bit of trouble seeing the hexes over the foliage, but I think I can get close enough to hit 4 snakemen on the other side of the path without hitting the mercs.)) No longer worried about stealth given the near-deafening peal of magical thunder, Nalomanterys calls out "Dormio!" while making a set of intricate hand gestures. He blows a pinch of sand into the air, which shimmers and glides toward the ambushing snakemen on the other side of the trail. [spell] sleep [/sleep] at rank 3.

Starting with the lowest HP, the 4 snakemen on the most top-right corner must absorb the amount of HP rolled, if they absorb their current HP, they fall asleep. 37

Just in case it magically changes, I rolled a 43. I'm not sure if there's a way to roll flat dice on the character sheet so it goes into the game log, so I did it this way.

CON:  4

The Yuan-ti nearest Danica is knocked momentarily senseless, stunned until the end of Meili's next turn.

Nalomanterys completes his spell and watches as... none of the Yuan-ti across the way are affected.

Mica frowns and peers into the jungle trying to see what Danica was pointing out as she whispered. He barely had time to process her instructions before the sounds of the ambush echoed through the jungle and Danica rushed forward. Cursing, he rises up from the ground and follows Danica, only a little surprised to see the speedy Meili rush past.  Mica moves up and strikes the same Yuan-Ti Meili attacks, slashing three times with his hand axes. (rolled with advantage due to stunned condition.)

Attack: 21 Damage: 4.

Attack: 20 Damage: 8.

Attack: 20 Damage: Unable to parse dice roll..

plus 5 colossus slayer damage.

Grimacing at the chaos she was surrounded by and added to, Danica pulls her scimitar from her belt. She was just glad at how quickly the Seekers were to act. Seeing that Meili and Mica are handling the threat closer to her, she rushes forward to the more monstrous looking serpentine person ahead of her and tries to take a slash at him. 

Movement: Up 10/15 feet to attack the big snake guy
Scimitar  Attack: 17  /  Damage:  6

After Mica's attacks, the stunned Yuan-ti is looking to be in really bad shape.

Danica advances and strikes the yuan-ti malison (type 1) with her scimitar.  The blow wounds the creature, which drops its bow and draws forth its own scimitar.

Finally, the ambushed mercenaries get their wits back and join the fray.  "Get off the trail!" one of them cries!  "Close on them or we'll be butchered like pigs!"

Seeing the yuan-ti malison (type 1) Danica is fighting, the three mercenaries at the front of the pack charge it, wielding their longswords in two hands.  "Remember the Golden Eagle!" they shout.

• Longsword Attack:  17  Slashing Damage:  13
• Longsword Attack:  18  Slashing Damage:  10

• Longsword Attack:  8  (Miss)
• Longsword Attack:  21  Slashing Damage:  12

• Longsword Attack:  6  (Miss)
• Longsword Attack:  17  Slashing Damage:  8

With the last blow, the scimitar-wielding yuan-ti malison (type 1) falls.  The three men all look upon Danica with battle-hardened eyes, not lowering their swords.

[If anyone tries to interact with the mercenaries, include either a Persuasion or a Deception check, depending on the tack you pick to follow.]

The two who were thrown off the fallen elephant scamble up.  Most of the arrow fire is now coming from the NE side of the trail, so the hustle around to the near side of the elephants body, using it for half-cover.  They raise their heavy crossbows and line up shots against the Yuan-ti peeking out from the far side.

• Heavy Crossbow Attack:  23  Piercing Damage:  11

• Heavy Crossbow Attack:  22  Piercing Damage:  4

The last mercenary, at the back of their procession, pulls off her helmet and cries, "Harambe!  No!"  She rushes forward and kneels beside the fallen elephant, pulling out a poisoned arrow and checking for vital signs.

The two yuan-ti malison (type 1)s who hoisted the net last turn, now draw their bows and target the grief-stricken animal handler.  

• Poison Arrow Attack:  15  (Miss)
• Poison Arrow Attack:  11  (Miss)

• Poison Arrow Attack:  10  (Miss)
• Poison Arrow Attack:  5  (Miss)

Despite her complete disregard for her own safety, the arrows all miss, sailing harmlessly past her while she searches in vain for a sign of life from the elephant.

The last remaining yuan-ti malison (type 1), on the far side of the trail, holds it bow and speaks to one of the hidden crossbowmen.  "You are sssurrounded.  Throw down your weapon, ssstand and sssurrender.  It isss your best chancsse at mercssy...".

[WIS Save:  4]

The crossbowman shakes his head, then says, "It's right.  It is our best chance."  He lays down his crossbow, then stands, loosening and dropping his swordbelt in the process.  Then he raises his arms high above his head in surrender.

(There's a lot that's happened here - how many yuan-ti are left on the southwest side; and can't quite make out the hexes on the map but how far away is Ran? - he looks like he's quite far from the action)

[Ran, the only dead Yaun-ti is the blue-headed one closest to Danica.  The white background one closest to Danica is stunned and badly wounded.  Ran is about 55' away from the wounded white background one and 60' away from the topmost white background one.  If any of that helps.  

I agree, there's a lot going on... I'm trying to limit myself to one map update per round.  As you drew the worst initiate and will have to deal with the most out-of-date map each round... you have my deepest sympathies.]

"Bloody hell," Ran says. He'd been trying to hide in the dense brush, got distracted by his own chainmail making noise and trying to figure out how to quiet it down all the while quite sure the damn bird was laughing at him when all of a sudden the jungle erupts in noise, chaos and mayhem.

"What happened to fair warning?" Ran exclaims. "Ah sod it."

He starts shouting and barreling through the jungle, running more or less in a straight line north west, looking for whatever the group has decided to fight with.

Movement: 30' NW

Action: Dash 30' NW

Ran races forward through the underbrush, emerging next to Mica and Meili, who are busy punching and stabbing a vaguely feminine looking creature with the upperbody of a humanoid and tail of a giant serpent.  Nearby, Danica squares off with a pack of angry looking soldiers in black breastplates with golden birds stamped on as a design.  As he takes in the scene, he feels the bird leave his shoulder and flee up into the tree tops.

Round 3

As the crossbowman waves his hands in surrender, the yuan-ti malison (type 3)s   all train their bows on him and unleash a hail of arrows. 

When it is over, he seems to snap out of his magical compulsion, still alive but now badly wounded with 8 arrows sticking out of him.  He looks around, confused at why he would have so exposed himself.

Meanwhile, the two non-stunned yuan-ti type 3s on the SW side distance themselves from the melee combatants, moving NW and SE, respectively.

5. Ran     

The change in the battlefield layout for the moment went over Meili's head. The snake archer was still here, still standing (even if stunned) and she kept attacking the creature:

Attack: 21 Damage: 8
             14 Damage: 7

aiming at another weak point in the snake's body to keep the creature stunned (One more Stunning Strike).

[If the purple yuan-ti is still alive and Meili's attacks hit, another stunning strike at it. Afaik, since it is stunned already, it automatically fails Strength and Dexterity saving throws and remains stunned]

Forgot advantage!!! Another roll for the secont attack: 24

Meili's assault finishes off the stunned Yuan-ti.  [No need for a stunning strike - it dies on the second hit.]

Then can Maily run to the yuan-ti below to SE? Her speed is 40ft. If so, Flurry of Blows on that yuan-ti with an attempt of Stunning Strike on it:

Attack: 21 Damage: 5
             7 Damage: 5

Stunning Strike if attacks landed Strenth DC 14.

Watching Meili finish off the Yuan-ti archer they had grouped around, Danica turned to stare down the mercenaries who were looking at them none-too kindly. Meeting their eyes, the elf states calmly, "I understand your wariness but how's about we work together to fight the snakes and then talk it out?" 
Holding their gaze for just a moment, Danica deliberately turns away from them and begins following in the direction that Meili had darted, knowing there were two strays that way. "Don't let them surround us! We've got this."

She thought of attempting to heal the crossbowman that had been shot multiple times, but knew that casting magic (even to heal) on one of them right now probably wasn't the best idea. Hopefully he would hold out until a little more trust was placed. Making her way purposely towards the blue scaled abomination, the druid flung out a hand towards it, a thorny vine springing out from her palm like a whip in its direction. 

Persuasion: 6
Movement: 30ft SE straight towards big buff blue snake
Thorn Whip Attack: 1+5=6
Thorn Whip Damage: (Didn't even bother rolling)

((*Stares at +0 Charisma* Why is Danica 'Captain' again? xD ))

At Danica's words, two of the mercenaries, still panicked, look ready to take AOO at her while she moves away.  Another, perhaps a leader, stops them.  He looks at Mica (the last Seeker still close to them) and says as quietly as possible, "OK then.  Help my men on the trail.  The three of us," he gestures at himself and the two swordsmen with him, "will sweep north and then flank the Yuan-ti on the other side."

Mica watches Danica and Meili sprint off to the south east and turns his attention back to the leader of the mercenaries.  He cocks his head at the man’s words, briefly looks back toward where the others went, then meets the leader’s eyes and nods.  “I will do what I can, now hurry.”  Mica rushes forward through the jungle toward the trail,  breaking through the underbrush behind the downed elephant and hisses at the one weeping over the beast “No time for that, get under cover and fire back before you join him!” 

Mica reaches into his belt pouch and rubs his thumb across an old piece of quartz while letting out a sharp whistle as he connected with the primal spirits to summon beast.  I hope that old dwarven shaman knew what he was talking about, he thinks to himself.  Mica was rewarded a second later as the brush next him rustled and a lone velociraptor emerged, slightly shimmering with a fey glow.  The beast paused on the trail, sniffing the air and making a few clicking noises before responding to Mica’s gesture and racing across the trail to strike at the center yuan-ti archer.

Beast Attack: Attack: 18 Damage: 12.

(OOC: The creature acts on Mica's initiative but after his turn, so I assume it gets an action the same round the spell is cast.  If not, I can retcon.)

Nalomanterys's hand dips into his component pouch for sulfur as he considers the flammability of this rainforest... ((fireball)). Apparently he decides it's too risky, and instead simply sends a beam of frost toward the snakeman that Meili is attacking. ray of frost

attack: 18

Damage: 11 cold
