Goraseth keeps his concentration on his bless spell. He then runs toward the closest Gobelin via the gentle slope with one torch in hand and if close enough slam him with his shield.

attack: 12
damage : 4 without adding the strength modif

Tryn hurries after Goraseth up he slope as far as his short legs would carry him (Y8 by my count) and calls after the goblin (blue), “I’ve seen you falling, careful!”, with magically induced words, that are aimed at distracting and frightening the goblin. 

Int save, goblin: 6 (from portent roll) plus his int modifier and int safe proficiency for 1 damage.

Slashed and arrow ridden, Progo is starting to reconsider his choice to run into the middle of the goblins, thankfully it doesn't appear to more in waiting up here. Progo needs to upgrade armor. Planting his feet against the 2 in front of him (BA: Steady Aim) Progo lashes out at the one without wounds, hopefully unexpectedly:

Attack: 2 plus19 Damage: 7 plus 7 sneak

Goraseth by my count you would not be close enough.

Progo, that goblin surely did not expect that blow, and died quickly and quietly, as life escaped his body quicker than he could realize what happens.

Tryncaryn, after your words, goblin grabs his head and shrieks in pain and confusion. When you were changing the fate od that goblin (using the portent roll, since goblin rolled 12) a weird vision came to you in that instant moment. Will it be true or not, it is hard to tell, but it is a glimpse to a possible future. /I will not use any of those rolls in spoiler/

Tharanau looks around and realises that Progo is in deep trouble. He runs towards the slope to get a higher vantage point and shoots at one of the goblins attacking Progo (is any of them already hurt? Then I'll shoot this one). 
This time the ray of ice cold crystals finds its target (19 to hit for 5 dmg)

Hes trying to taunt them: "Ha, you're afraid of me! Stop running away, try and get me!!"

 (The red one was hit pretty badly by Progo the last round)

Tharanau finishes the red goblin.

Orange Goblin runs toward east, and slices Progo on the way. (11+4=15 to hit) (1+2=3 dmg)
Blue one tries to run away to his companion, however it goes hard for him, as his limbs are cold and it is hard to coordinate them in that state. He looks back and shoots at goraseth, but can not hit.

/i hope i got it all right now :P/

Goraseth should be able to make it just to the blue goblin and smack him with the torch

Attack:: 18, damage 3 + 1 fire

Tryn runs after Goraseth (to Y3), cursing at the goblin (blue) with another Mind Spike for 2 damage (unless he saves with a DC12 Intelligence ST).

(Tryn can’t see the orange goblin in the darkness, sadly.)

Blue goblin is dead with smoldering gap in his chest and splintered torch protruding from that wound. 
So Tryn you can revise your turn if you want, before rest of the team posts.

With the goblin felled by Seth’s torch, Tryn ups his step and dashes towards Progo (to U1).

Tharanau is trying to get further up the slope and cast a spell at the same time, but slips and the concentrated magic energy emanating from his hands sends a frosty feeling down his spine, making it tingle, instead of flying off towards his enemies (rolled a 1 to attack).

Can Progo see the last goblin from where he is?

right now he does, it does looks like that goblin is going to run down the scarp, but is still visible right now to you with darkvision.

After the slash at his back fades his vision, almost slumping over. Unfortunately Progo has felt this before, but he is able to snap himself out of it, keeping his feet (Relentless Endurance feature). Seeing the goblin who made the blow running away Progo drops the raiper and pulls an arrow out. He plants his feet as he takes aim really hoping the other goblins are delt with that were behind him. (Steady Aim Bonus Action).

Attack: 1 plus 13 Damage: 20 with sneak damage 

Progo tenses his leg muscles slowing down what seemed to be fatal bleeding. Takes aim, sees the goblin sliding towards the edge of the scarp, shoots and sees as arrow plunges into bak of goblin head. Then disappears with him below the edge.

Fight is over, you are victorious.

do you push towards your destination? it should not be too far by your calculation it might have been here so surely excavation should be close. (dm honesty it is really close like 10 min trek) or maybe you do something else?

“Progo! Are you all right?” Tryn yells preoccupied.” It looked like you would go down for sure! Blasted goblins! I’d run right in their trap if it wouldn’t have been for Tharanau’s keen senses.” Tryn hurries after Progo to check on him and help him down to the fire place.

Goraseth rejoins his companion and cast cure wounds on Progo (+ 10hp). "Sneaky ones, these gobelins. I'll be tempted to actually use their camp to rest but there could be more than these four. We are probably not too far from the excavation."

“Yeah, I also would prefer to call it a day but if you think we can make it to the dwarves, that’d be best.”

Tharanau checks on Progo and the others, glad that they're ok and that Seth is helping Progo  

Before leaving, Tharanau tries to look for clues around their campsite as to why they were here and what where they hoping to catch. Were they hunting? Did they have anything valuable with them? (Investigation 10, perception 23)
