The party slowly creeps down the passage into the room. The cavern appears to be a 40ft. x 40 ft. room. 
Half of the cavern is taken up by 2 large pools that start from the north side of the cavern and stretch down to about the middle of the room. These pools are now devoid of water and you guess this is the source of the flood the party faced. 
A narrow waterfall near the northeastern part of the cavern feeds these pools with a steady stream of water. The water flows to the western end of this cavern and appears to be the source of the stream in the tunnel. 
The western area of the cavern has rocks of every size thrown about the area. This must be where the explosion occurred. 
A small exit, with stone steps, can be seen along the west wall of this cavern, just below the stream and there is a much larger exit along the south wall of this room, 20 ft. from where the party is standing. 
Sounds of the waterfall echo throughout this room making it hard to hear anything. 

(OCC will post the map in the morning)
Actions?

Sully presses on ahead of the party giving them one last reassuring grin along the way. 'Well ain't they some clever son of a gun' Sully thought as he passed the now empty pools, but doesn't let them distract him for long before focusing again on the forefront of him. Another thought then occurs to him. But though he spares a look back at Eddie with a question on the tip of his tongue, he catches himself, squints off to the side, and then shakes his head while getting a moe on for the base of the stone steps. Although just before coming around the corner, he'd hold up his shield arm in a signal for the others to wait for a second as he strained his ears to try and pick up anything around the corner.

Perception: 16. [8]

"Nuthin... Aight, on me." Sully whispers back to the others before moving to creep up the southernmost steps for a look at what awaited beyond them.

Kae looks over the dry basins, somewhat impressed with the ingenuity of their design. When she hears Sully proclaim a lack of noise with a degree of confidence, she looks at him and raises an eyebrow. "Hold up a sec, Sulls. I'm trying to visualize this place... won't we be walking towards where Eddie found that cop? And didn't he say there was somebody else in that room? Not to say it's a no-go, just be extra careful." Kae then creeps after Sully, trying her best to follow her own advice.

"That's what I'm already figuring, Kae-kae. But unless there's an off-tunnel we're missing in the shadows, this be the only way forward. So be ready." Sully had stopped to whisper back as much, but remained otherwise determined to follow through on his path. If anything, the reminder led to a more determined set to his face and to his tightening the grip on the bat in anticipation of introducing the would-be kidnappers to a much deserved comeuppance! 

Abruptly 3 goblins come from out of the exit to the south.

Initiative! 
Goblins: 18

Initiative: 14 (12 + 2)

"How many of these guys are there?"

"No idea Sully, but what I do know is that there's about to be 3 less of them. Let's give these guys the Smackdown".

Initiative: 16

O.O.C. Edit: That should be Kae not Sully. Sorry guys. I'm scared if I edit the actual post it will change my roll on the initiative.

Initiative: 9.

"Alright ya butt munching punks. Have at it if ya want." Sully stated as he readied to swing with his bat.

Initiative Order:
Eddie: 16
Kae: 14
Goblins: 10
Sully: 9

The goblins are armed with crossbows and spiked clubs.

Eddie and Kae may act. 

"I didn't think I'd have to use this, but... desperate times, desperate measures."

Kae rifles through her pack and pulls out what looks to be some sort of closed metal tube. She chucks it at the goblins, but unfortunately she misses, and the tube harmlessly impacts the gray stone floor. Or so it seems. As it makes contact, the device kinda latches onto the cavern floor. After a couple seconds of worrying whirring (say that five times fast) emanating from the tube, a spring within it releases, sending the cap flying into the air... and a ton of (biodegradable) glitter with it. The goblins only have a split-second before they're all covered in a brilliantly-glowing, inconvenient, and ever-lasting surprise.

ACTION: Faerie fire (DC 13) on the gobbos.

 It appears that the modifiers dropped off my rolls. It should be a +5 to hit which makes it a 16 and +3 on the damage which would make it a 7.

Kae's spells only hit one of the Goblins. Seeing her body glow, she runs towards the south exit of this room yelling "Magic, Magic!" 

Eddie shoots one of the goblins with his bow. The arrow sinks deep and the goblin drops to the ground.

Angered, the 3rd goblin fires his crossbow at Eddie.
Attack: 16
Damage, if hits: 5

 The bolt sinks deep into Eddie's chest but he remains standing. 

Sully may act. 

"Ohhhh, that ain't coming out easy mc greasy. But not worry! I got the answer for your woes right here!" Sully says in common before stepping forth swinging his bat and aiming to take at least one glowing goblin out by the knees before turning his attention to the rest. 

Ac: Non-lethal Baseball Smack at nearest Goblin. 
Attack: 11 Damage: 8 non-magical bludgeoning.
