"I agree, we should send them all back to their makers, for that is exactly what they would have done to us!" Flick says to Tharn. 

(DM: What is the best way to do this? I guess RAW says attacking an unconscious creature has advantage and automatic critical hit, if within 5'. Should we all continue with attacks on each of the three unconscious sahaguin?

Turning to the elf, he adds, "Well met, Delaford! It seems as if your presence on the beach is perfectly timed! And what an impressive display of sword work, my friend! Now help us finish off these nasty web-faced sea savages!"

Seeing that nobody was moving to follow him, Barrion turns back in time to hear Delaford's introduction.

"Hold, friend Flick, and listen!  I pray every day that the Everlight would shine upon our path, but at the moment, I can't help but feel as one who is stumbling in the darkness in fear.  Brave elf, how certain are you that the people of Palma Flora are good?  I'm certain not all of them are.  Now that I've had a moment to gather my wits, I have the suspicion that we have inserted ourselves into the middle of something, rather than the beginning.  I confess these creatures are foreign to me.  Do any of you know them to raid the surface unprovoked?  Perhaps, they do; I don't know.  However, if it turns out that the villagers started this fight, will you kill them in their sleep, as well?  Clearly, we have already chosen a side, but would mercy to these three make us enemies of Palma Flora?"

"I am not certain. However in a town this small, the chances of good people is a possibility. This shark hunting tournament seems like it happens every year. I do have that same question. Why now would the creatures harm them? I do not think we will be enemies are we were here to protect the people and children who were on this beach."

Tharn shakes his head. “We are wasting time.”

He turns to Barron. “You were right; sounds like these four weren’t alone. I don’t want them behind me when they wake up, so tie them up or I’ll put them down. We need to move.”

”Barrion, my good man, I have only been in Palma Flora for a short time, but I have lived by the sea my entire life, just a short ocean breeze from here. Believe me when I tell you, friend, Sahaugin are evil creatures through and through, gills to bone.”

“We coastal dwellers call them “sea devils,” and they’re just as quick to slaughter entire ship crews as kill the inhabitants of seaside towns, and for what? Not because we provoke them, but simply for greed and sport.”

”now if you would rather tie these three sea devils up and question them, then I suppose that is your choice, but you had better make sure your knots are tight.”

”Now, either way, we need to make a decision, because my spell only lasts a minute at most.”

(I love when I can just sit here and watch characters interact with each other)

(OOC: I'm assuming we're still in order of initiative, since there are more sahaugin about. Are we at Flick or Delaford?)

"I for one, have no plans to resume this madness. Barrion, if you would like to keep one alive and tie him up, then that's certainly a safer option than letting them all live."

With that, Flick quickly strides towards one of the sleeping sahaguin, and pulling forth his rapier, attempts to kill the creature by stabbing it in the chest. 

Attack: 15 Damage: 11

The sword goes deep into the sahaugin’s chest, as you notice it go limp on the blade.

"We will leave just one then." 

Delaford will step up to the sahaugin next to the one Flick has slain and use her short sword to kill it as well.

Attack 23       Damage 4

If the sahaugin does not fall, she will use her bonus action to use her other short sword

Attack 20          Damage 6

Edit: OOC: Thanks Flick. 

Additional Damage Dice 8

OOC: Delaford, make sure you another damage dice to each attack, as it's an automatic critical hit when attacking unconscious creatures. :)

The other sahaugin falls into a pool of blood on the ground.

"I don't know knots." Tharn brings his battleaxe down on the neck of the last sahaugin.

Attack: 11 Damage: 17 (assumes advantage and a crit due to unconsciousness)

If this is fatal, he moves up beach in the same direction Barrion had been heading, looking for other attackers. "Let's keep moving!"

As Flick watches Delaford and Tharn quickly dispatch with the other two sahaugin, he moves towards the the last sleeping one. Holding the point of his rapier just above the creatures's heart, he says, "It's almost a pity that these dastardly sea devils weren't able to watch themselves be cut down by our blades and see firsthand the consequences of their ill-intended actions. Now, let's quickly tie up the other one."

"Do any of you have some rope?" 

"Aye, Flick. I have about 50 feet. Is that sufficient?"

Taraven will hand Flick 50 feet of hempen rope.

"Perfect!! Now help me tie him up! You other two, keep your weapons on him just in case he wakes up before I'm done"

With that, Flick takes the rope, uncoils it, rolls the creatures over onto it's stomach, and begins wrapping it tightly around the sahaugin's lower legs, then warps a few coils around the creature's arms and hands, finishing the whole thing as tight a knot as he can muster. 

"There! Hopefully that will hold."

(DEX check with advantage, assuming that Delaford helps.) 20

Taraven will help Flick tie up the last sahaugin. 

"Looks good enough to me. Now what? Barrion, I will keep watch while you question the creature."

Taraven will switch places with Barrion and keep watch for other approaching sahaugin during questioning. 

(OOC: Do we still hear any other noise of attacking sahaugin elsewhere on the island?)

(Yes. It seems like a sizable force has attacked.)

(OOC: So that I'm on the same page: Tharn's blow didn't kill the third Sahaugin or wake it up, yes?)

"I think we should stash the creature out of sight and go defend any helpless villagers.  If any of us share a tongue with the creature, a conversation should wait until the fighting is over."
