Can I safely attack with a dart from where I am without hitting anyone in the party? I'm still a little lost on our positioning and need some guidance here.

If so, I attack with a dart from my current position. 

Attack: 9

Damage: 10

If not, I'm going to hold my attack for this round and try to move to a better position that I can attack from next round.

You are off the map at this stage, but within Dart range, but only Goblin (1) is within sight.

Flemig

With a heroic effort, your dart sails true.  It pierces the eye of the Goblin (1), who falls backward with a final cry of pain.

Khloe, your up

Khlöe will try to get into range with whatever goblin is closest take a strike with her staff.

Attack: 6

Damage: 7

If she can't get close enough she'll move as far as possible and hold an attack should any enemies come within range

Khlöe

Khlöe moves up, but her path to attack is blocked by Erevan, but she seals off any chance of escape.

Goblin (4)

Attack: 11 Damage: 4

The Goblin, hoping to clear a path of escape, lashes out with his scimitar, scoring a painful hit on Khloe.

Allistar

Allistar casts his Eldritch Blast, sending a beam of energy to hit Goblin 3.

Tanirall

You are up.

Tanirall will move forward to attack Goblin 4 with his battleaxe. If I can’t get within melee range I will stay where I am, or move where I can see him if I can’t, and throw a javelin at Goblin 4.

Battle axe Attack: 23

Javelin Attack: 13

It didn’t roll my damage for some reason

Battle axe Damage: 8

Javelin Damage: 5

Tanirall

Tanirall moves up behind the line and launches javelin, striking the Goblin (4) in the chest, causing the Goblin to take a step a half-step back in pain.

Round 2

1. Goblin 3 (3 Dmg)
2. Maya
3. Zansnut
4. Erevan
5. Flemig
6. Khlöe (7 Dmg)
7. Goblin 4 (5 Dmg)
8. Allistar
9. Tanirall

Goblin 3

The Goblin takes aim at Erevan with his short bow and fires, and strikes him in his left shoulder.

Attack: 13 Damage: 8

Witnessing her comrades take hits, Maya would maneuver her way to be back to back with Khloe to keep an eye on the northwest corridor.

 She'd cast Cure Wounds on her most injured ally.

Round 2

Maya

Maya moves to protect Khloe's back, casting her spell on the wounded Eravan, she takes up position to watch the hallway behind.

Echoingly, she hears the tread of running boots.

"More are coming." Maya would communicate to the others.

It seemed to Zansnut that the team had things well in hand. With Maya warning of more people incoming he thought it would be best to hide. There was no telling who else would arrive. So he squeezed himself closer to the crate and crouched down.

Erevan, Flemig, Khloe... if you want to give me your moves.

I'm not seeing myself marked on the map, so I'm assuming the following is ok. Let me know if not.

Flemig, buzzing with excitement over his newfound dart throwing skills, launches a dart at one of the remaining goblins (#4 on the map).

Attack: 18

Damage: 9

As soon as the dart leaves Flemig's hand he sprints towards the NW corridor, where Maya heard the footsteps.

To Kasian: I'd like to end up near Maya, but not beyond her into the hallway. 

Round 2

Flemig lets loose his dart, and with great accuracy buries it in the Goblin's (4) artery.  With a cry and a spurt of blood, the Goblin topples backward to the floor.

OCC:  You can move between Maya and anyone, but this would interfere with "controlled space" during combat.  That is people might get tangled up.  I can place you N or Kl if that is of interest.

Yes, move me North of Khloe then. I want to be close to the NW corridor without being totally in it, so that seems like the best option.

Khlöe will turn to the NW hallway and will ready a dart if she has a clear sight without hitting anyone.

If can she'll immediately throw one the minute anyone that isn't part of their group approaches 

Erevan will swing for the goblin next to him with both swords.

Action: attack with shortsword on goblin (4): Attack: 13 Damage: Unable to parse dice roll.
Bonus Action: attack with offhand shortsword: Attack: 8 Damage: 6

OCC:  Erevan, your attack would have proceeded Flemig's awesome dart throw.  However, both are misses.

Round 2

Erevan attacks, swing both swords, but the Goblin (4) catches the first on his shield before swaying out of the way of the second.

Flemig lets loose his dart, and with great accuracy buries it in the Goblin's (4) artery.  With a cry and a spurt of blood, the Goblin topples backward to the floor.

Freed from combat, Khloe turns to face the approaching footsteps.

OCC:  Allistar, you are up... only Goblin 3 remains...
