Rohuzar, both your slashes cut deep, the silvered edge on your blade seeming to sizzle at it cuts through the hide of the wererat.  It does not fall but its tail sags and its bravado seems to be spent.

[Do you mean run past them down the hall?  Or back to the other barricade beyond the door you came out of.  There is no barricade past these two wererats.]

(oh my bad, I thought there was a second barricade that guys were working on at the end of this hall. If the rat is still up, I won't move, anyway)

Grugga is struck by the first of the sewerfolk's blows, but quickly falls into a fighting posture and parries the second blow. His wound is barely more than superficial right now, but it'll smart in the morning.

"Damn it!" He bellows. "Damn fools! Don't you want to live?" Scrunching up his face, he knows that this is a fight for life or death. Thinking of his friends behind him and how they rely on him for a clear path forward, he brings his sword down in a flurry of blows designed to kill. He aims first at the transformed wererat; if it dies he aims at the sewerfolk above him.

Attack 1: 23; 7 slashing (magical)

Attack 2: 10 (+ 5 bardic inspiration); 8 slashing

If the wererat dies, he will move to flank the sewerfolk with Rohuzar

Still having some focus on keeping the dark gate open, Aubrey moves to shove the blocking barrel out into the tunnel beyond, then peeking out of the broken door and using the eldritch powers of his talisman to unleash two golden beams of eldritch crackling force towards the closest still standing sewerfolk.

Eldritch Blast: 22 Force: 5
Eldritch Blast: 20 Force: 5

He then uses the power of his talisman to force the sewerfolk closest to the dark gate back towards it before moving back again.

(Telekinetic shove Str save 15)

Save: 3

Grugga's blade leaves the human-looking werewat nearly gutted, but somehow still alive.  He looks as though a strong wind would finish him off at this point.

Down the other end of the hall, Aubrey's eldritch blast kills the wererat in front of the door, while his invisible shove pushes the transformed wererat back to the very edge of the inky blackness.  He curls his tail around him to keep it from falling in.  From within that darkness, a final, choking scream is heard.  [No need to roll Hunger of Hadar damage... wererat still inside only had 1 hp remaining.]

The two wererats with Grugga and Rohuzar share a look, expecting they are about to die fighting for their home.  Both focus on the mighty Grugga, seeking to leave a mark by which he might remember him.  The un-transformed one cries, "The clan must live!  If you won't join us - If you escape -  you will lead the other topsiders to our warren!"

Wererat (transformed):

Bite - Attack: 22 Damage: 6

Shortsword - Attack: 21 Damage: 7

Wererat (not transformed)

Shortsword - Attack: 8 Damage: 8

Shortsword - Attack: 15 Damage: 8

Back at the other end of the hall, the wererat dragged by Raqisat is unarmed and screaming as he struggles to get free.  "Whoa!  Stop!  I surrender!" he shouts as he also tries to break Raqisat's grapple: 4

The transformed wererat squeals something that might be 'Release him!' as it scrambles back from the edge of the Blackness and attacks Raqisat.

Bite - Attack: 21 Damage: 4

Shortsword - Attack: 12 Damage: 6

Aubrey, from his position far down the hall to the left, Furvus reports that there is no sign of any approaching reinforcements.  If anyone does come, this battle will be long over before they arrive.

At about the same time, Aubrey and Cosette hear something new.  It is coming from back in the storage room where you rested.  It sounds almost as if someone spilled a basket of bouncing, squeaking tennis balls.  The sound grows louder, echoing in the enclosed space... until you see a writhing carpet of dirty fur pour into the hallway behind you.  5 Swarms of Rats have entered the fray!

Round 4!

1. All of you!
2. All of them!  And Rats!

[PS - Should anyone get bit, don't roll the CON save.  I have something else in mind.]

Rohuzar makes a pair of wide swings left and right, looking to cut up the transformed one first

Attack: 17 Damage: 11 

Attack: 25 Damage: 15 

     Raqisat is hit by the bite attack but takes half damage due to rage...  He manages to sidestep the shortsword attack, partly in accident as he is struggling with the one he still has in his arms. The warrior had been tempted to release his captive when they said they surrendered, Raqisat was an honorable man after his own fashion, but being bitten and attacked by blade before he could even decide made that decision for him...

     Raqisat moves ten feet forward til his tiptoes are all but inside of the murky darkness of whatever that is and releases his captive in front of him - into the darkness.  ((I *think* the movement being halved while I push/carry/drag him is all I need to release him in front of me, since once released we cannot both occupy the same space?  But if DM decides I need to take an attack action to shove, then so be it... Strength check: 5 but 17 due to advantage if needed.  Hoping it's not. lol...  If shove action is needed, Raqisat's turn ends there.  If he can just set him down in the darkness then...))

     Raqisat then pivots to the transformed piece of rat that just bit him and attempts to grapple him as his just did with his friend.  

Grapple Attack: 11 or also 11 due to advantage...

     If somehow that succeeds Raqisat would attempt to pivot back towards the inky darkness and release him into it as well...  Raq still has 10' of movement needed though is just basically pivoting...  But all this release into the inky darkness does seem a little "cheaty" to get two attacks in when he only gets one per turn so... DM's discretion :)

Edit cause:  OH!  Advantage on Strength Checks due to rage so... doing second rolls and editing them in.

Grapple:  4

Rohuzar cuts down both the transformed and un-transformed wererat on their side of the fight, leaving the way out unblocked.

[Raqisat, I'm using your abortive shove roll as your contest against the grappled wererat's 4 to escape.  Your 5 wins!]

Raqisat marches the pleading wererat down the hall and releases him into Aubrey's screaming black horror hole. Then he turns, grabs the other wererat, and deposits him inside as well.  Both of them scream as they disappear into the blackness.

For the moment, there are no enemy combatants visible in the hallway.

"Time to move on Ms. Cosette." The young noble says with a quick smile, motioning for the archaeologist to squeeze past him again and out into the corridor beyond, then, while still keeping some focus on holding the dark portal open, he uses the powers of his talisman to block off the narrow corridor with magical fire, hopefully making the rats hesitate before pursuing them, then shoving the closest swarm back,  then following the bard out through the broken door and stepping away to the left. "Hurry, use that barrel to seal off the hole in the door again, there are more rats coming, veritable swarms of them in fact." He quickly says to the others as he gets out into the outer corridor.

(Minor Illusion and Telekinetic shove Str save 15)

"Mmhmm." Cosette agrees, it was time to move on. "Yep, we are bein' tailed." Thanks to Raqisat for doing the literal heavy lifting and clearing the way for her via Aubrey's hungry tentacle black void garbage disposal system, she's able to nimbly maneuver her way through the opening into the hallway.

Cos figures if the rats found their way through their prison walls to get behind them, they will quickly, if not, eventually make their way through a barricade. "Allow me teh thin the herd." She pauses Aubrey from fully blocking her field of vision on the swarm with the barrel before she could time her next well positioned whistle. The sharp sound pierces down the depths of the hallway into the heart of the swarm.

"Raq, be a dear an' wrangle the left overs." Satisfied with her effort, Cosette would begin to make her way down the hallway to the others. She trusts he would cover her rear, Raqismashing the tenacious vermin brave enough to trail them.

With every sewerfolk neutralized for the moment, Leelan stows his bow and heads west down the tunnel.

"Right then! Off we go. Let’s not dally long enough for them to come back with reinforcements."

"Yes, let's get out of this place." Grugga holds up his small glowing crystal to provide a direction for the visually unevolved and heads west. "Furvus said the cellar leading to the surface would be this way!" Grugga passes by the hallways leading further down underground and heads toward the heart of the wererat city. "Hopefully we can make it above ground before we see more of them."

Aubrey successfully shoves the first swarm of rats back into the pile, putting all 5 swarms within the range of Cosette's shatter.  Tufts of fur and entire rats are thrown airborne in all directions within the narrow hall as the spell goes off.  Whether the remaining rats are fooled by Aubrey's illusory fire, or just knocked senseless, none of them attempt to pursue any further.

Raqisat, you hear a gurgling scream as the transformed werecreature is consumed by Aubrey's spell.  The other man scratches you with human fingers and tries to pull himself out and past you.  When he is able to get his face out the darkness, he again howls his surrender.  

Will you let him out, or attempt to hold him inside the darkness?

Grugga, where are you trying to lead everyone?  Using the map on post 3086 for reference?

     Raqisat will grab the man and help drag him out of the darkness.  "Accepted, assuming none of you attack me again," Raqisat snarls.  "And you explain why you all took us captive when we had such a good working relationship developing!"  Raqisat holds him still near the darkness, he is wanting the threat of tossing him right back in during this quick little interrogation.

     "Leading us the quickest and safest way out will go a long way in ensuring your continued survival as well..."

While trying to intimidate answers and directions out of the man (Intimidation:  13...) Raqisat also is trying to read the man to see just how honest he is being or if this whole surrender is just a tactic to lead us to more danger.  (Insight: 11...)

The man-shaped wererat gasps, shivering from the cold and brushing bits of acid off of himself.  

"We... we was just trying to protect ourselves.  Most of the other foreigners to come through have been weak scout types.  Nobody really expected you to kill that horror downstairs... yet you did, and didn't have much of a scratch to show for it!"

"If... if you wouldn't join us... then we was afeared you would spill all that you know of our tunnels and homes down here... that you would lead more like you back here to destroy everything we've built!"

Looking over his shoulder at the whining darkness, he squirms and pleads to be put down.  

"So you admit to having sent us off into what you expected to be certain death." The young noble says with a quick wry smile, calmly coming up behind Raqisat. "I admire what you built down here, and that you survived in this harsh environment, I really do. Unless you give us more reason to I doubt we or anyone else would try to destroy what you have down here. As you might imagine we find ourselves somewhat disappointed over how you treated us but I'm a practical man and I'm sure we can still find some mutually beneficial arrangement between our two groups." He continues with a friendly smile. "If you can provide us with detailed information about your clan and help us to negotiations with your king we have no reason to not let you live." He finishes with a sincere and comforting warmth in his voice.
