Ithelion looks at the array of attackers in front of her, moves a little to line up her shot, and fires at G1.

Attack: 21 Damage: 5

Daemyar downs his bottle of fire breath and spouts a gout of fire at the rats and goblins

DC 13 Dex save for half of 12 fire damage

Krom calls down a pillar of fire from Moradin on the rat he can see

Action: Casts Sacred Flame on R1, DC 13 Dex save or take 1 radiant damage.

R1 Dex save - 20

Ithelion is able to find an opening in spite of Daemyar blocking her somewhat, and the arrow thuds home - a hit!  It sticks into the rat's tough hide on the top of its body.  It snarls in response!

Daemyar gulps the precious potion down and, as his belly rumbles loudly, belches a torrent of fiery vomit at G1!  G1 dex save 5

Daemyar's fiery blast burns the goblin to a crisp and it falls to the ground, broken and charred, leaking pus and blood.  G1 is dead!  R1 is able to dance out of the way of Krom's holy fire!  

G2 drops its bow and pulls out it's scimitar and throws itself up against the wall at E7, just as R1 moves into the middle of the doorway.  The rat makes an attack on Daemyar: Attack: 22 Damage: 6 

G4 runs up, bow in one hand and a clay flask in the other.  It moves to F8 and throws the vial at the floor at Daemyar's feet: 9. It then uses the rest of its movement to get to F7 where it ends its turn.

Erky moves a little bit, trying to put eyes on anything.  Finally, he sees the rat!  He quickly whispers a few words and points his finger and a soft purple light descends on R1.  Dex save for R1 (DC12) - 1 damage on a fail.

Shere is up!

*dex save for R1 - 12 

*the goblin's throw overshoots Daemyar's square and lands where Ithelion is, coating the sqaure and her feet and the hems of her robe/cloak.

With all the folks in the way Shere Decides to mock the rat in the doorway wisdom save DC13 2

R1 is visibly shaken!

G1 has been toasted by Daemyar, so G3 is up.  At this point, you all begin to smell something burning - the acrid smell of smoke...

G3 moves in front of the doorway, a flaming arrow nocked in it's shortbow!  It aims in front of it but angled a bit down...Attack: 12 Damage: 3

...the goblin's arrow skips along the floor and ricochets away, missing its intended target!  The goblin retreats back to where it came from, out of your sight...

You hear Shamir growl and yell, "Idiot!" in goblin.  Shamir runs into view, a flaming arrow as well, and shoots at the oil at Ithelion's feet:  Attack: 20 Damage: 8 before retreating back out of sight...

 Shamir grins, blows a kiss and winks at Daemyar as the flames jump up in Ithelion's area - take 5 fire damage - and a billow of smoke rises up almost immediately.  

Stabby, Sharpie, and Garnet are up!

Stabby and Sharpie shoot at the last rat.

Stabby first - Attack: 17 Damage: 3 

 Stabby hits!  But the rat still stands and Sharpie will line it up as well:  Attack: 18 Damage: 6

The great goblin duo are able to skilfully weave arrows through the fray of battle and take down R1!  The rats are dead!

Garnet - she continues to wait [unless she says otherwise]

Krom, Ithelion, Daemyar, G2, G4, R1, R2, Meepo, Erky are up!

MAP

Daemyar will flourish his blades as he runs past all the goblins in an attempt to deflect their attacks while he moves to get in front of Shamir and block the door out.

“You run from the inevitable, Shamir! Dishonor finds all cowards!” 

He then blows another blast of fire at the hob.

DC 15 Dex save or take 14 fire damage

Daemyar, tell me the path and where you end up.

Also roll a Dex save.

I think E8 to F9, then just straight shot to the door ahead of Shamir. So I think two attacks of opportunity, although at disadvantage for dodging (and using ranged weapons in melee). 
Dex save 10 

(( When the Goblin lit the oil, Ithelion needs to make a save; her actions in her move will depend upon the outcome of Daemars action and what happens if/when she saves... ))

Dex save: 6

Daemyar begins to move forward through the caltrop area but steps on one of the spiky traps and forces him to stop.  Take 1 point of damage.   [do you want to do anything else?  your movement is over but you still have action(s)]

Ithelion notices the flaming arrow too late and fails to properly get out of the way.  The flames flare up, burning her for 5 points of burning damage.

Krom, G2, G4, Meepo and Erky are up!

Krom will again call down some holy fire on the goblin next to the door.

Action: Casts Sacred Flame on G4, DC 13 Dex save or take 8 radiant damage.

(Edit: I realized that Ithelion was higher in initiative than Daemyar so could not reasonably wait to see what he did)

As the flames begin to rise at her feet, Ithelion ignores the growing pain knowing that she will pay a price. She moves a little to the south and east to take aim at the goblin she can see in the corridor. As she does so, she instructs Elosa to distract it then describe what she sees in the corridor, and finally return to Ithelion.

After loosing he arrow, she leaps backwards out of the flames, shocked to see how much damage she has taken. She douses any flames that try to linger on her travel clothes, thankful that the oil did not hit her directly.

Attack: 20 Damage: 11

Attack visible Goblin (G4).

((If none visible, wait for Daemyar to complete his action ))

[Okay so just breaking down what happened...]

Ithelion reacts to the oil flaring up (fails) and takes the damage (5) once. 
Daemyar then attempts to navigate through the [items]caltrops[/item] (fail) but has to stop once a couple lodge under his feet.  He is immobile at E8.  [though he still has his action/bonus action but no response to that, so unless they say something we can move on...]
Krom peeks out and calls upon his deity to strike down the vile beast (G4) - Dex save - 21
Ithelion moves forward to D8 and tries to sew a shot through traffic to G4 - it is a hit!  The combination of the elf and the dwarf attacks on G4 are enough for it to crumple to the ground, dead.  Ithelion moves back (C9 to B8 to avoid the oil).
Meepo stays put, making sure the dragon stays unconscious.

As Ithelion moves through Erky's area, the deep gnome brushes her slightly, causing her to regain 7 hit points.  "Aim true, lass!" he comments before turning his attention back to the chaos.

*Daemyar has taken/took the dodge action - I assume that's still what he is doing.  If he wanted to take a bonus action to blow fire, he can say that.*

Shere, you're up!

MAP 

Ithelion sighs with relief and smiles down at the gnome, "Thank you". She looks at her bow a moment, "It's not seen use in anger for many decades."

She glances across at the two goblins and shakes her head slightly, "This is a sad business for all, but must  be hard for you. Call out if you think you can persuade anyone to lay down their arms. We have no wish for more death."

Daemyar changes gears and dashes (bonus action) after Shamir and attempts to knock him over
