"We might as well be clean about it, then," Tanakir mutters.

He produces a shining javelin from his pack, moving so that the group in the ship is between him and another group (if possible). He'll dash if he needs to, but if he can move and keep his action, he'll activate the Javelin of Lightning, hurling it at a random kobold in the farthest group.

Attack: 26 Damage: 25

Lightning to anyone in between (DC 13 Dex for half): 14

Gruun moves to keep a solid front and prevent anyone from getting surrounded. If they move into range he'll use his Greataxe(ready action)

DM Screen:

Javelin of Lightning vs. Kobold (Disadvantage-Range): 8 Damage: 26
Kobold DEX Save: 21
Kobold DEX Save: 16
Kobold DEX Save: 8
Lightning Bolt Damage: 15

Enemy Attack Rolls:

Four kobolds of the further group, to the left, collapse into a slumber in the midst of their run, victim to Rycider's magic. To the right, Tanakir hefts his javelin, which crackles and reforms into a bolt of pure lightning. It sizzles across the beach, splitting three kobolds in half before returning to javelin form in the torso of a fourth kobold; in horrifying fashion, however, the kobolds do not die, but continue to split apart and mutate rapidly, each side becoming a thinner and sicklier kobold.

Aradurk's taunt does not slow them in the least. The seemingly feral creatures toss a volley of stones across the sudden battlefield. Though a couple of stones strike Hox, and one bounces off of Rycider, they are largely ineffective, most landing short or sailing past, into the drink. The kobolds continue to scream their battlecry as Hox dumps oil upon the half-buried deck of the ship. Gruun moves forward with Killian.

Round 2 Order:
Players <=====
Kobolds

Placement:
One group of six kobolds is 20 feet below Hox, 5 feet away from Gruun, Killian, and Tanakir, and 30 feet away from Aradurk and Rycider.
One group of two kobolds is 40 feet away from Hox, Gruun, Killian, and Tanakir, and 70 feet away from Aradurk and Rycider.
One group of ten kobolds is 40 feet away from Hox, Gruun, Killian, and Tanakir, and 70 feet away from Aradurk and Rycider (opposite the group of two kobolds).
Four kobolds are asleep, 70 feet away from Hox, Gruun, Killian and Tanakir, and 100 feet away from Aradurk and Rycider.

Health:
Hox is lightly wounded.
Rycider is lightly wounded.

Hox readies another flask and chucks the alchemist's fire at his oil spill. Before it even hits, he beats a hasty retreat towards the party with a dash.

(Do I need to do an attack roll for the alchemist's fire?)

Using all his movement, Aradurk closes to the nearest kobold group. Rapier in hand, he targets the nearest foe. 

Actions:
1st Attack: 25 Damage: 11

Burn 1 superiority attack to use Trip Attack if the attack hit (STR save against DC17) or be knocked prone with 7 additional damage to the target. 

2nd Attack: Attack: 23 Damage: 15
(presumably with advantage if to the prone creature) 

If 1st target still lives, attack again else move on to the next target:
3rd attack: 28 Damage: 10 

Killian closes with the group of six near her, laying into them with her longsword.

Move: To close the distance (20') with the first group of kobolds.
Action: Attack twice with longsword +1.

Attack 1: 22 to hit, for 17 magical slashing damage
Attack 2: 23 to hit, for 18 magical slashing damage
Savage Attacker (feat): if this damage total is higher than one that hits above, use this instead, please: 12

OOC: Help me understand Hox's intent here, so I don't resolve the alchemist's fire in a way that's entirely different than what you're expecting. What is that he's aiming to do?

Giving some more time for Gruun, Rycider, and Tanakir's actions before botting.

(Oh, I want to start a fire. I wasn't aiming for any of the kobolds but the area where I spilled the oil. I had to throw it since the thing combusts once it is exposed to air, catch a few of the kobolds in it. And I was hoping to use the oil and/or the wood from the ship wreck to cause the fire to grow. Make a hazard of sorts.)

Tanakir pushes away his surprise at seeing the kobolds split and multiply, bringing up a hand to send a sheet of flame at the nearest kobolds.

DC 17 Dex for half of 7 fire.

OOC: Botting Rycider with vicious mockery and botting Gruun with two greataxe attacks at the nearest group of kobolds.

Removed alchemist's fire from Hox's inventory.

DM Screen:

Kobold WIS Save: 18 Damage: 7
Greataxe vs. Kobold: 25 Damage: 9
Greataxe vs. Kobold: 19 Damage: 14
Kobold DEX Save: 6
Kobold DEX Save: 14

Enemy Attack Rolls:

Aradurk wades into the oncoming kobolds, slicing the first apart at the knees and knocking it to the ground. Even from the horizontal split, two kobolds begin to mutate and form, but the half-orc ends both swiftly before they can rise. No mutations split from this already mutated pair. Killian slices through two more, each of them spawning a pair of kobolds themselves. However, when Rycider shouts a bardic insult toward another, it falls dead, and no other kobolds rise in its place. Tanakir incinerates one with a cone of flame, singeing but not killing another kobold nearby.

The wrecked ship begins to blaze, the oil on its deck exploding to the alchemist's fire that Hox slams onto it. The intense flame quickly begins to melt through the old wood into the hull below. Gruun joins the front line, hacking through two more kobolds that each spawn a mutated pair.

Even with their sheer numbers, the kobolds have yet to strike decisively against the party; as another wave of slingfire comes in, only minor wounds are taken.

Round 3 Order:

(I finally realized Hox has had a shortsword.)

Hox takes out his shortsword and descends down into the melee. Seeing the strange kobolds grow from remains, he tries to knock out one.

Sneak Shortsword Attack: 24 Damage: 43

Reaction: As a Defensive Duelist, I add 5 to my AC for 1 of the attacks that landed. 

Aradurk looks confused at the behavior of the kobolds and swings into his targets. 

Attack: 17 Damage: 8

Attack: 19 Damage: 13

Attack: 19 Damage: 13

Killian knew they would do that (split and regenerate) from that first round, so she just lays into them again, hewing kobold bodies around her.

Move: Stay with the first group of kobolds, unless they are all dead, then she will close with the nearest group and...
Action: Attack twice with longsword +1.

Attack 1: 26 to hit, for 14 magical slashing damage
Attack 2: 30 to hit, for 16 magical slashing damage

Tanakir draws his club, applying a shillelagh before swinging a green-flame club at the nearest kobold.

Attack: 25 Damage: 22

14 fire to a nearby kobold if the attack hits.

OOC: Botting Rycider with vicious mockery and Gruun with two greataxe attacks for this round.

DM Screen:

Kobold WIS Save: 7
Greataxe vs. Kobold: 30 Damage: 18
Greataxe vs. Kobold: 22 Damage: 9

Enemy Attack Rolls:

Aradurk carves through three of the small creatures while Killian erases two of her own. Another has its skull caved in by Tanakir, which becomes a ball of flame that strikes yet another in its face. Gruun sprays a kobold across the beach on his way to the pair approaching from the left. The last remaining kobold of the group fails to see Hox descend, planting the pommel of his sword in the base of its neck and knocking it solidly unconscious.

The charging kobolds ignore Rycider's mockery, but Gruun becomes a wrecking ball, occupying the pair on the left and announcing his intent with a decapitation. From the headless body, two mutated kobolds emerge.

The remaining group, ten kobolds strong, splits itself into two forces. Half of the group charges in to the fray, practically leaping over themselves to stab at Aradurk, Killian, and Tanakir, while the others remain distanced with their slings, sending stones at whoever they see.

Round 4 Order:

Action: Attack twice with longsword +1.

Attack 1: 25 to hit, for 14 magical slashing damage

Aradurk raises his rapier in a posture to denote, "Come and get it."

Reaction: As a Defensive Duelist, Aradurk adds 5 to his AC  (total of 24) for 1of the attacks that landed. 

He moves into the group of 5 kobolds, sneering as he swings:

Attack: 30 Damage: 15

Tanakir keeps swinging, doing his best to keep the kobolds from drowning them.

Attack: 17 Damage: 21

Fire damage: 13

OOC: Apologies everyone. The days got away from me.

Not giving up after one loss, Rycider will try again to take down a kobold with words alone. She aims her Vicious Mockery at one of the sling wielding creatures.

Damage: 9
