Eddie lifts his bow again and shoots at the final Goblin.

(I assume this is the one which Faerie Fire applies to as no-one has taken an attack with advantage yet. If so the advantage procs Eddie's sneak attack).

Attack: 20 Damage:11

"Guys, I don't think I'm gonna be able to walk this one off. Anyone got a Band Aid handy?"

Sully races forward and strikes a goblin. It immediately drops to the ground.

Eddie fires another arrow at the fleeing goblin and it drops. 
All goblins are down. 

Everyone hears movement coming from the exit to the south. Then a guff voice calls out.

"What tha hell do you guys want?" it calls in a deep baritone voice.

"World peace."

Kae slowly yet deliberately takes her makeshift crossbow off of her back and aims it towards the voice.

"Also shelter, safe national parks, fewer kidnappings, to not be shot at while innocently walking down a path, and to be able to enjoy a road trip with my friends. But mostly world peace. You?"

Sully tries, but fails in biting back a snort and snicker. Then once Kae deliberately keeps up the request he finally risks a glance over the shoulder to shoot her a soft but disapproving glare for the earnest request, even if a bit of a BIG ask of a kidnapper. "Part from the national parks bit as nice as it would be, but it would be pretty swell if you hand over the cop -- alive and well. Then, I s'pose we can go our seperate ways. Otherwise.... yea, shoot -- otherwise I'm afraid we'll be making a bit of a citizen's arrest. So, what'll be, Bub? Ya wanna play it cool, or is me and my crew here gonna have to make sure your next mug shot includes a busted chops wide open." He says, trying to sound intimidating.

Intimidation: 9.

The voice laughs a deep wicked laugh.
"You just don't understand who yer dealing with do ya?" he chides. 

"Well, you can stop hiding and enlighten us if you like, but I think we already got an idea. Little green guy," Kae takes one hand off her crossbow and holds it horizontally a bit above her hip, "'bout yay high, I imagine. You certainly sound post-pubescent, but if I'm being honest, I don't think a big voice alone is going to make you too much stronger than all the little green guys we already got past. Which I guess brings us back to the topic of getting those binds off of that officer of the law back there." Kae puts her hand back onto her crossbow, keeping it securely focused on the direction of the voice.

"Here goes nothing" Eddie whispers quietly before his body begins to blur and shimmer and Kae and Sully see his features melt into nothingness before being replaced by those of a half orc in his late 30's or early 40's with long black dreadlocks and scars on his face. He waits a few seconds before a deep, gravelly voice comes out of the throat that was once Eddie's and says "Looks to me like we ain't the one with no idea who they're dealing with. You're just a scumbag in a cave. I'm a road captain of Joking Gypsies MC and my prospects have had no problem beating your buddies into a bloody pulp. Our brothers in the Ironrock chapter have business with that there law man and have sent us to collect him on our way through. Now we can do this the easy way or the fun way.

The easy way is my 3 prospects are going to walk in there, take the law man off your hands and the walk right back out again. The fun way ... well you're probably not going to like the fun way but that's when the prospects take a backseat and all 12 of my road brothers get let loose on you. The choice is yours Bub.

But word of advice, make the right one or my man Chains here might get an opportunity to test out his new whip, see if the salesman was right and the barbs are sharp enough to skin a man while he's still breathing. "

Eddie's body then transforms into that of a halfling with a wispy beard and soulless eyes. In a high pitched voice, almost sadistic voice the halfling says excitedly "Oooh boss can I? Can I really? I can't wait to see how beautifully she tears the flesh and what pretty patterns she'll make when the blood flies".

After putting on the little show Eddie's body returns to that of a normal teenage boy.

Sully clicked his tongue and muttered something under his breath. But then in taking advantage of the others still engaging the voice, he'd began looking around near him as if searching for something. Out of the corner of his eyes he does catch Eddie's transformation and is given pause, as it'a been a hot minute to say the least since Eddie ever showed such powers. However, a quick shake of the head has Sully snapping back to attention and eventually finding a fair sized pebble.

He nearly drops it from trying to suppress a snicker over Eddie's act towards the end, but somehow held things together long enough to imbue the light of Helm into his chosen rock while keeping it tightly enclosed to keep its light from escaping it. But not just yet, anyhow. Sully meant to wait a little longer to see how the voice responded to Not-Eddie's threat..

 Need a Deception roll and Intimidation roll from Eddie. 

Deception: 5

Intimidation: 3

A deep guttural laughter erupts from the south passage.
"Well Hell then," a booming voice echoes throughout the cavern. "Come on in an' let's get to it!" 

Actions?

"Sure thing. Just don't say the boss didn't warn ya." Kae procures a similar contraption to the one she just used, though this time she takes a moment to pack some extra glitter into it. She winds up her arm and lets it go, throwing it as close to where the voice is coming from as she can in a hope the ultra-fine particles will spread around any necessary corners. The cylinder latches onto the ground and erupts a second later, showering the area in a shining, biodegradable rainbow.

"Oh, right. You might wanna close your eyes."

Faerie fire (DC 13) as close to the voice as possible, within a 20 ft. cube 60 ft. away

Eddie readies his bow and positions himself behind Kae and Sully "Sorry guys, I really thought that would work. You're probably going to have to take the lead here".

"Hey dude. Ya tried yer best, and honestly even I was a bit scared for a second there." Sully hurriedly whispers back to Eddie as well as gives him what he hoped to be a reassuring smile. Then in the wake of Kae's light show, his expression hardens as he either wound up throwing his own lit up rock at the hopefully lit up speaker, or as closeby as he could from as far as he could tell! Although just to spook them that much more he yells out, "Gnomengarde out!", half-hopefully the series of explosive artifice would be infamous enough to make the speaker panic and dive out of cover. 

No matter what happens either which way, Sully charges into up(or down) the stairs and into the adjoining chamber or passage soon after during the confusion with his bat drawn once more, hoping to capitalize on the confusion.

To DM: If you need a deception to go along with the above, feel free to roll it on my behalf to keep things going. 

The party hears movement from the opening in the southeast corner of the cavern.
There is a growl as well. 
Kae launches her cylinder.
Sully throws his lit rock.
((Need a roll since  Sully & Kae are "aiming" for a specific spot, just to make sure neither one doesn't fling their respective item and it bounces off the cavern wall.))

(Not sure what kinda roll you want, so I'll just roll a flat d20 and list a few possible modifiers.)

d20: 2
Spell Modifier: +3
Spell Attack Modifier: +5
Dexterity Modifier: +2
Modifier with proficient ranged weapon: +4
Athletics: +0

 yea, I wrongly focused on the cylinder rather than it was just for the "flavor" of the spell so, no need to roll.

When Kae's "glitter bomb" goes off, it covers the entire entrance.

"Aw, look at all tha pretty colors." comes from the opening. "It will take more than that to take out Klarg!" he yells back. 

Sully charges down the stairs and finds a 30 ft. wide x 35 ft. long cave. Kae's glitter bomb has coated the walls of the entrance and halfway into the room. 

Sacks and crates of looted provisions are piled up along the south wall of this cave.
To the west, the floor slopes towards a narrow opening that descends to a small cone-shaped area with a hole along the west wall. the echoes of the waterfall in the room Sully just left, bounce around the room making it hard to hear anything else. 
In the middle of this room is a large smoldering fire pit. 
On the other side of the pit, lying on the floor, bound and gagged, is a middle-aged man in a police uniform. He is partially covered in Kae's glitter bomb. 

A voice comes from the west, from behind a couple of stalagmites.
"So this is tha gang that is gonna cut inta Klarg's turf eh?" says a dark bestial voice. "Eat 'em up Ripper!" he yells.
With that a large mangy wolf comes charging in from behind a stalagmite. 

Initiative! 
Ripper: 15
Klarg: 8
Goblin 1: 17
Goblin 2: 17

Eddie's Initiative: 8
