“Get ‘em, Ferg!,” comes Effulgyn’s muffled voice from inside the apple. 

Ferg steps into the fray, just in front of Arc, and sends a thunderous gust of arcane energy at the mound, hoping to catch all four (known) goblins in its wake. The first goblin with the singed hands miscalculates when to peek out above the mound and takes the spell's full power right in the face. His lifeless body is blown 10 feet backwards and his companions laugh at him no more.

It doesn't take much for the second goblin, the one who took acid damage earlier, to succumb to the spell's energy--he perishes mid flight, his last breaths full of dirt and rocks and arcane dust. 

The third goblin manages to roll out of the way, missing most of the spell's wake by mere seconds. She does take 4 points of bludgeoning damage as the second goblin's shortbow gets caught in the gust of energy and lands on her head. 

The fourth goblin is just as lucky. On his way out of the tunnel he realized he'd left his weapon sitting on the ground and bent to pick it up. In doing so, the frayed wood of the door that splintered into an even more murderous spike missed his eye by inches, landing instead just across his scalp, sticking there in a large splinter sort of like one would wear a feather in a cap. 

OOC there are no signs of other goblins--just one that's still lying on her belly at the opposite side of the road and the one that is still in the tunnel.

Fin you're up if you want to try going after the goblins but they are still partially obscured, meaning you would be at disadvantage. However--Parson's helping has not yet been used so you can use it now to cancel out disadvantage if you like. 

((I'll move forward as close as possible, which I believe still puts me short of the mound, and try something very un-paladin-like: Mind Sliver on the first goblin I can actually see. INT save at DC 13, takes 5 psychic damage and -1d4 to its next roll on a failure. If you can't see very well, rely on something that just needs the hint of a glance ;) ))

Fin moves quietly 10 feet in a somewhat diagonal direction, hoping to catch a glimpse of any part of the belly-down goblin's form. She is partially obscured by the mound itself, but also by her weapon, which covers the lower half of her face. She is presently still trying to get the bolt into the weapon, but because she has it laid down horizontally it's proving a bit tricky--she's not used to holding it this way.  The movement of her head and her hands is what catches Fin's eye and without a moment's hesitation, he sends a bolt of psychic energy into her face. She convulses and while Fin is too far away to see it, her eyes roll back into her head in agony as she begins to relive the worst day of her life in such agonizing detail that it literally consumes her. She lies dead, bolt still in hand.

(Interesting aside: the worst day of her life was actually today for obvious reasons but also because a few hours ago when she found out that Mrkch, her brother, had been exiled from the clan for stealing from within the horde. It was her worst day because actually, she had been stealing and while she was glad he got the blame for it, she knew her days of squirrelling away extra coins was over and this thoroughly bummed her out. Her death then felt like the personification of unrequited greed.)

It's Parson's turn in the order with just one Goblin left, still making their way out of the mound door. He's got a good sized splinter in his head, and blood dribbling down his face. He is carrying a shortbow as well. 

((That was an awesome roller coaster of detail. Rofl))

As mentioned Parson will perform the help action again for whoever is next to make an attack role against the goblin.

 (Lolololol!)

Effulgyn’s defensive spell ends, the huge apple disappears, and the halfling blinks in awe at the effects of Ferg’s second Thunderwave. ‘You’ll be a great wizard someday Ferg, I know it,’ he thinks.

Leaping back atop the mound to view the fourth, injured goblin, the young wizard’s brow tilts forward in the darkness, and his irises glow with arcane light as he shouts, “B’djet Q’imbti!,”. A tiny blob of green acid comes into being, whistling a merry tune. Effulgyn points an eyebrow, and the blob shrugs, then screams in its tiny voice,“Q’imb-Tiiii!!!,” and flies at the goblin, its tiny form clenched in effort.

(Action: cast Acid Splash: You hurl a bubble of acid. A target must succeed on a Dexterity saving throw ( DC 12) or take 1 acid damage.)

Effulgyn's tiny green blob of acid flies at the goblin's face at record speed, and in his panic (not to mention the rivulet of blood still running down his face, obscuring his vision) the goblin is unable to duck completely out of the way. The acid lands on the helix of his formidable ear, tearing a hole right through it.

The goblin takes up his short bow and aims at Fin who is, again, the tallest and closest target (so much easier to see) but then he seems to think better of it. 

Truce! he yells, letting the bolt of the short bow fall. "I surrender!"

He drops to his knees, groveling. 

Arc you're up. You have the one Goblin now on his knees about 20 feet from you, with no sight of any others. 

Arc will take aim and fire his crossbow at the remaining goblin. To hit 18

Damage 9 (if that’s a hit) 

Despite being on his knees and begging for mercy, Arc aims his weapon at the Goblin and fires a bolt from 20 foot range--not typical for a weapon of this nature so the arrow goes wide, missing the Goblin's chest. 

OOC Ash is next, still running toward the mound. He is now 120 feet away.

Ferg you're up! The goblin is on his knees about 20-25 feet from you. Arc just tried to kill him with his crossbow at close range. 

Ferg stops and considers the situation.  He walks to the Goblin and in common he will say to the goblin "Drop your shortbow" as he picks up the bolt.  "Why do goblins attack first and think second?  What is the place?  Are there more goblins inside?"

It's nothing! Goblins have to live somewhere don't we? the goblin shrieks, sounding terrified and exasperated in equal measure. He has dropped his weapon and looks up at Ferg expectantly. 

OOC Fin you're up. (I'll keep you in initiative for a bit)

"It's got a point. We were the intruders here." Fin yanks the arrow lodged in his armor free and throws it down. "Although I don't appreciate the hostile reception. You really should warn before you shoot."

((What is the general outlook on goblins? Are they savage little raiders, second-class humanoids, or just like anyone else?))

 This is a good question! I have not obeyed the longstanding rules about all orcs or goblins being evil so I think it is good advice not to assume alignment on a race. I am leaving it up to you to determine the true nature of the characters. I would be happy to have the players roll whichever skills checks they feel necessary to figure it out and will do my best to describe things meaningfully now that I have found my groove in this kind of campaign!
