Lia takes the disengage action and moves behind her companions.

Rhok curses under his breath at the crossbow not hitting anything, knocks another bolt, and fires again at the monster

Crossbow:  Attack: 27 Damage: 14 

Colossus slayer damage:  2 

Lia gets out of the monster's reach, dodging its tentacles as Lothlién's fire bolt hits the monster.

Seeing a companion retrating, Don-Jon lets go of his sling and moves forward to stab the beast with his twin daggers.
Attack: 7 Damage: 3
Attack: 17 Damage: 2
Attack: 15 Damage: 1

The monster retaliates agains Don-Jon, swinging its tentacles and trying to bite this pesky human that just stabbed him twice.
Tentacles: Attack: 12 Damage: 4
Bite: Attack: 14 Damage: 5

Don-Jon's con save against posion: 7

The overseer is paralyzed by the poison, still alive, but looking bloodied.

Initiative order:
16 Carrion Crawler (22, slowed by Ray of Frost)
13 Xarroth (20)
11 Rhok (20)
  9 Lia (3)
  7 Lothlién (17)
  1 Don-Jon (28)

Xarroth goes next. After that I'll resolve Rhok's action.

OOC @Morden_Defmark: since Rhok critted that last hit, you get to roll another d8 for the colossus slayer damage.

OOC: Oh cool! forgot about that

Second d8 roll for the crit:  2 

Xarroth continues to scrape together the effort and fires another beam of blue-white at the creature. If this will not be the last, there will be another, and another, and as many dazzling platinum scales cover his ever-radiant hide in heavenly peaks...

Ray of Frost
Ranged Spell Attack: 20 Damage: 2 (cold)

Xarroth's icy bolt hits the monster, slowing its advance again. Rokh's bolt hits the frozen spot, driving ice shards deep into the monster's body. It's looking heavily wounded.

Initiative order:
16 Carrion Crawler (42, slowed by Ray of Frost)
13 Xarroth (20)
11 Rhok (20)
  9 Lia (3)
  7 Lothlién (17)
  1 Don-Jon (28)

Lia goes next.

Lia shoots it with her crossbow...

Attack: 18 Damage: 9

Lia's bolt flies forward and hits the monster on its open jaw. A couple spasms later it lies down dead. Don-Jon is still paralyzed next to it.

OOC: we're out of initiative order.

"Well, hopefully that was the last of the dangers in this place..."  Lia says as the creature finally falls. She glances to the overseer.  "Hurts like hell, but he should snap out of it any moment..."

"Should we take a rest while Don-Jon gets better?" Lothlién proposes

"That only sounds wise. We can do what we can to try and make the recovery as efficient as possible..." Xarroth looks over Don-Jon, seeing if there's anything he can do to aid the recover.

Medicine: 5

Rhok will aid Xarroth in trying to get Don-Jon rid of the poison effects

"I could definitely use a rest to heal and regain my spells" he says

Once Don-Jon is recovered, Rhok would see if any of his spent bolts are salvageable

"If you find any bolts with simple breakages, pass them here, human, and I will see what my spells can do." Xarroth calls to Rhok as comes to find no new information on Don-Jon's condition.

"A rest sounds good." lia confirms.  "I think we leave it to the overseer to get people to clear out the rest of this place." She suggests.  "We have broken the back of the wererats, so, if any are still alive, they won't be much of a threat any longer.  I vote we rest up, then head on our way again, we still have to check out those other things remember."

Xarroth goes over to Don-Jon, but is unable to find a way to counteract the poison. After a minute or so, he regains control of his body and sits down next to the fallen monster "that's something I don't want to feel again, nice to see that you made that beast pay for it."

Rhok is able to find the two bolts that missed the monster, which Xarroth mends after seeing that Don-Jon is out of danger.

You go back to the miner's hiding place, checking the last unexplored tunnel. It's a 20 feet long tunnel that ends abruptly, at the end you find the stabbed to death miner's corpse that Sabastian had seen on his previous flight.

The miners welcome you back to their hiding place "I'm glad to hear that you have rid the mines from those wererats" remarks Falkrunn Frostbeard, with a smile on his face "we can rest here before doing a full check tomorrow if you prefer. But I'm afraid that we don't have any food to share with you."

OOC: full map, as it is on the encounter description.

Rhok would be wondering what time of day that it was, and about the mine's security. "Do you have a way to secure the front entrance to ensure that any other parties of these wererats can't waltz into the mine?"

"We could stack dirt barrels to block the entrances" replies Falkrunn "a proper gate would be better, but it takes a while to forge one of those." Don-Jon agrees with the experienced dwarf and adds "if those varmints have not bothered you all in here, the barricade can wait until morning. That fight was enough work for today."

You arrived at the mines mid afternoon, the sun should be close to setting by now.

Lothlién offers help to set the barricade before they all go to sleep. "I sure will rest much better if I feel safer. It is still early, we can move those barrels before we sleep, and we'll still be able to wake up early tomorrow to take the road"

Lia falls into a bed, wherever she can find one.
