Leng the Wanderer |

Ah, I didn't realize I had an opportunity for an action - I thought 'move' meant literally just moving on the map!
Leng keeps his weapon spinning and without missing a beat he sends the weighted end snaking out again at one of the rats in a flurry of strikes.
Attacking rA. Flurry of blows.
Kusarigama attack: 1d20 + 2 ⇒ (10) + 2 = 12 (includes +1 for lingering inspiration)
Kusarigama damage: 1d6 + 3 ⇒ (5) + 3 = 8 (includes +1 for lingering inspiration)
Kusarigama attack: 1d20 + 2 ⇒ (18) + 2 = 20 (includes +1 for lingering inspiration)
Kusarigama damage: 1d6 + 3 ⇒ (3) + 3 = 6 (includes +1 for lingering inspiration)
Since rB and rC will have to move in to attack, I'll roll my attacks of opportunity now, just in case.
rB:
Kusarigama attack: 1d20 + 3 ⇒ (12) + 3 = 15 (includes +1 for lingering inspiration)
Kusarigama damage: 1d6 + 3 ⇒ (5) + 3 = 8 (includes +1 for lingering inspiration)
rC:
Kusarigama attack: 1d20 + 3 ⇒ (17) + 3 = 20 (includes +1 for lingering inspiration)
Kusarigama damage: 1d6 + 3 ⇒ (6) + 3 = 9 (includes +1 for lingering inspiration)

Den Sarment |

The druid slices at the rat placing his shield squarely in front of the creature's mouth and aiming for its neck. The attacks are a series of nasty jabs and twists into that jugular.
Scimitar attack: 1d20 + 2 ⇒ (19) + 2 = 21
1d6 + 2 ⇒ (2) + 2 = 4
(Poss crit) Scimitar attack: 1d20 + 2 ⇒ (10) + 2 = 12
1d6 + 2 ⇒ (3) + 2 = 5

Draken the Thylacine |

Draken slinks up next to the shield and slashes his claw towards the left leg of the rat. Its almost like she doesn't want the taste of that dirty rodent in her mouth.
1d20 + 2 ⇒ (3) + 2 = 5, 1d4 + 3 ⇒ (3) + 3 = 6
That disgusting creature proves too nasty for the thylacine and she never gets close to the target. Her lips curl back in naked aggression and frustration at the rat. Hackles and hair risen along the spine.
Intimidation: 1d20 - 2 ⇒ (13) - 2 = 11

Avogadro the Astounding |

Bring on level 2 so I can get some more useful cantrips...
Avogadro watches stunned as the rats emerge from the gloomy caves ahead. The tip of his new rapier wobbles as he holds it out, ready to poke anything that comes his way.
Full defence

GM Shady |

Den's strike hits home and the rat in question (rA) is badly wounded. Leng's strike (also on rA) finishes it off.
OK, Helien, want to move? Roll20 updated. Pip I think you can take your move now. Den - note Draken had already moved this round - by the time his next move happens the rat is dead. You can redo, but please keep an eye on initiative order (if it's easier, in future I'll assume Draken has no independent initiative; but, you wanted a pet, you have to look after him).
So, Helien still has her move for this round; Pip & Draken can move.

Helien |

GM Shady, if I can move past the others and into the free space, Helien will do so:
"Let us lock them down here" - the ranger presses forward to attack.
Move and attack.
Longsword: 1d20 + 4 ⇒ (9) + 4 = 13
Damage if it hits: 1d8 + 5 ⇒ (3) + 5 = 8

Pipernortin |

Pip steps over the kobold Helien left in the middle of the floor and comes bounding up behind the rest of the group. Though the passageway is blocked with bodies, he's pretty sure he can make out a big rat or two on the far side of everyone.
Which was reason enough for him to stay exactly where he was. Instead, he decides to keep the twisting tunnels well-lit for when Arnon inevitably charges blindly around the next corner.
Casting dancing lights!

GM Shady |

The rat manages to dodge Draken's snapping jaws.
Not sure I said earlier but this is round 4. As a reminder, initiative is { Pip, Draken } kobolds, Avogadro, rats, { Den, Arnon, Leng, Helien } so we are at the kobolds' turn. The ones you were chasing have obviously disappeared further into the den. But ...
The kobold, which had been dropped by Helien, wakes with a start, stands up and staggers a short distance back to the west (5ft).
Avogadro is up.

Avogadro the Astounding |

Avogadro catches the movement of the Kobold out of the corner of his eye and whirls round in a flurry of black cloth, with a soft murmur and a dramatic wave of his hand he attempts to hypnotize the simple creature
Casting Daze, DC14 will save to negate
"Someone grab that lizard!"
As he utters these words Avogadro advances on the creature, fancying his chances more against this one that the others that are no doubt heading towards them even now

GM Shady |

The kobold, apparently blinded and stunned, sits back down, now dazed as well.
I have had a few days at work along these lines, recently.
rC,Draken,Helien: 1d2 ⇒ 1
rD,Den,Helien: 1d2 ⇒ 1
The remaining rats make their attack, one (rC) on Draken and the other (rD) on Den ...
rC attack: 1d20 + 1 ⇒ (4) + 1 = 5
rD attack: 1d20 + 1 ⇒ (9) + 1 = 10
... both of them missing.
Den (but not Draken), Arnon, Leng and Helien are up.

Helien |

Helien swings at the rat in front of her - "These are probably pets for the kobolds, or they would have attacked them before and would not be here" - she reasons.
Attacking rC.
Longsword: 1d20 + 4 ⇒ (15) + 4 = 19

Den Sarment |

Den strikes out at his rat, his scimitar aimed at skewering a rodent. But the rat is a master of fighting for its own survival. And these have been trained by kobolds to be even more desperate.
scimitar: 1d20 + 2 + 1 ⇒ (19) + 2 + 1 = 22, damage: 1d6 + 2 ⇒ (3) + 2 = 5
Poss Crit: 1d20 + 2 + 1 ⇒ (17) + 2 + 1 = 20, damage: 1d6 + 2 ⇒ (5) + 2 = 7

GM Shady |

@Arnon - you're firing into melee and over soft cover so at a -8 penalty, even if you hadn't missed in the first place ...
I'm going to assume Den and Helien address different targets.
Leng's blow, and Arnon's arrow, miss their respective targets. But Helien and Den between them manage to kill the remaining rats stone dead.
You still have the dazed kobold to deal with, so technically not out of initiative, but you can post in any order.

Helien |

Seeing all rats down, Helien doubles back to tackle down the wandering kobold.
Do I need to roll anything GM Shady? Want to bind and gag him.

Avogadro the Astounding |

Avogadro takes an unsteady step back as Helien takes control
"All under cont... oh yes well... a masterful display. Magnificent woman."
He is quite ruffled by her prowess.

Pipernortin |

Pip rubs the bloody hole in his shoulder. The spear had torn straight through his shirt, but managed to avoid hitting anything too serious. It looked worse than it was, probably. "Well, that introduction could have gone better. Not the worst one I've ever made, though." Wincing, he prods a few of the rats with his foot, appalled by the carnage. Poor little disease mongers were just protecting their home, much like the angry little lizard fellows with pointy sticks. "I could be better, but I think I'm faring better than these little guys."

Den Sarment |

"Brave as you are, we cannot afford anyone to fall. Here let Erastil care for that Pip. Once we start fighting then perhaps Aaron can call on Old Deadeye more for sudden healing while I fight."
A familiar waft of meadows and poppies accompanies the healing magic as Den slowly eases the sore shoulder and watches the flesh knit back together. He smiles down at his companion.
"That's better. You know the hardest thing is knowing when to leave. If the fight gets too much then we should all be prepared to run as one. I don't expect any foolish and unnecessary bravery. Be careful. But Leng is right - those kobolds aren't in a talking mood yet. We need to beat that into them first."
Cure Light wounds on Pip 1d8 + 1 ⇒ (4) + 1 = 5

Helien |

Ok, in that case:
Helien makes sure the kobold is tied up and well secure, then stows her shield away, turning to the others - "I will scout the next room" - and inching toward the corner.
Stealth: 1d20 + 5 ⇒ (6) + 5 = 11
Perception: 1d20 + 5 ⇒ (5) + 5 = 10

GM Shady |

The next chamber - a large cave - is empty; there's no sign of the remaining escaped kobolds.
Three tunnels - including the one by which the party came, to the south of the room - intersect with the room. The other two entrances are respectively to the east and north. In each case, wide steps have been carved into the rock. A five-foot-wide circular pit is the chamber's only feature.
Roll20 updated.

Den Sarment |

"What is in the pit? It may be a fighting pit." Den moves closer to take a look down. He has Draken nearby.
"Perhaps we could listen at the different tunnels to see if there is a clue of their direction?" suggests the druid to Leng afterwards. He heads for the Eastern tunnel then.
Perception: 1d20 + 6 ⇒ (13) + 6 = 19

Avogadro the Astounding |

Avogadro follows the others, striding into the next room and, after a brief moment of adjustment, over to the pit. He looks into it.
"Any of you worldly types able to tell which way the lizards went? claw marks or stools all that malarkey, not my forté of course."
With a mumble and a wave of his hand Avogadro lifts his hat and several orbs of light emerge from beneath, drifting down into the pit bellow.
Casting Dancing Lights

GM Shady |

There are newly minted tracks on the ground, mixed in with a lot of older ones.
The pit seems to be a well. It's full of water, up to five feet from the surface. It doesn't seem to be too deep, maybe 10-20 feet plus the 5 drop to the water.

Avogadro the Astounding |

"Hmmm precious little fun to be had down there I think. So friends do we just wait, I'm sure our little lizard cousin over there..."
gesturing at the captured Kobold
"...will have lots of friends coming to his rescue soon enough, that or a cave in, or a flood, or... On second thoughts we may like to keep moving. Has he said anything useful yet?"
Nodding once more to the gagged captive

Den Sarment |

Den nods at the pair and starts to move ahead with Draken. He prepares to move on and makes sure that his shield and scimitar is ready to protect the rest.
"I can lead off with Draken unless someone else wants to guard the front?"

Den Sarment |

"Thanks Leng. Draken back behind me!" Den heads off to the east with Leng and Draken trailing behind. He moves slowly and carefully trying to hear round corners before the kobolds can jump them.
Perception: 1d20 + 6 ⇒ (15) + 6 = 21, Stealth: 1d20 ⇒ 19

Avogadro the Astounding |

Stealth: 1d20 + 2 ⇒ (14) + 2 = 16
Avogadro slips into his place in the order of things (near the back but not at the back) an creeps along with the others

GM Shady |

The path east drops down some steps, then bends to the south, opening into a large cave. Straw is strewn across the floor. The ceiling vaults to a height of twelve feet. Three ledges, eight feet off the ground, look out over the main cavern. A five-foot wide, twenty-foot deep trench runs north to south through the western half of the cavern, with just one five-foot wide bridge of natural stone allowing passage from one side to the other.
Will update I've updated the Roll20 map. Could you please move your counters on there?

Avogadro the Astounding |

Stepping into the bigger room Avogadro glances round, quickly taking in his surrounding with an eye used to reading audiences
With a flick of his long fingers he sends floating lights off to each of the shadowed ledges, hoping to see what lies above.
