Luthok is heading as far towards Dyoken as he can with his movement. "Really sponging it today, huh, Dyoken?" 
On his way over he attacks the spear wielding gnoll with his Chill Touch spell. (If he gets close enough this round he'll cast Cure Wounds (2nd level) Heal: 14

Attack: 18 Damage: 6

@Everyone - Sadly Adax can't stay on as a guest star - work got crazy! So you will have to deal with me... ] :)

@ DK's Reckless Attack Question - Yup! You didn't reckless until after they had made their attacks technically, so they didn't have advantage. Seems fair? However, as for your rage, you didn't say you were raging when you charged out there, did you? I'll let you retcon and do it if you had intended that to be part of the plan. I expect you guys to keep track of your resistances and doing the math on how much of the damage you actually ended up taking.

@ Muireach - They are now charmed and won't be attacking you directly, however, they are still hostile to the party. You have advantage on charisma checks, but you cannot compel these gnolls to do anything that would put them in harm's way. Basically, they aren't stupid.

Merrick, thankfully, doesn't get burnt to a crisp. We can't have Nana crying now can we? He takes a stab at the fire doggo. It whines from the lunge and tries to scan the tall grass for any sign of the kithkin.

Muireach successfully strikes the hound, and as he pulls his blade out an arc of fire erupts from the hound's own body - thankfully the pyres that fall don't harm any that are adjacent to the creature. The Spear Gnoll suffers a bit of damage as well.

Mercy hesitates for a moment. She isn't quite sure what Muireach's plan is, and lowers her curved blade. She seems [Ready] to attack the Bow Gnoll if it tries anything funny.

The Spear Gnoll will lash out at DK twice with its spear!

(Attack on Dyoken - Attack 1: 8 Damage 1: 10, Attack 2: 19 Damage 2: 9)

Bow Gnoll has its bow trained on DK. Its eyes seem to be scanning for someone, but at the moment it appears to be obeying Muireach...?

The Powerful Gnoll howls in Gnoll, (only those who speak Gnoll can read this)

With that, the Powerful Gnoll dashes 60 ft toward the ruins of the town! Lightning cracks through the sky with his departure. Mercy wasn't quite ready to deal with that, but you see a look of shock over her face turn to frustration as she contemplates chasing after that gnoll. 

Vivi, like Mercy, has her scythe trained on the Bow Gnoll and is [Ready] to attack if he shows any signs of aggression. She looks to Muireach, "W-What do we do?"

DK successfully damages and grapples the Spear Gnoll it struggles against him, but can't quite break out of his grasp.

The Hellhound, still alive, wheezes blood and smoke as it turns it's attention to Muireach. It seems to be on its last leg and hopes to take Muireach down with it!

(Attack on Muireach - Attack: 23 Damage: 4 piercing + 3 fire damage.)

Luthok's skeletal hand seems very sassy today as it does absolutely nothing! 

@Luthok - If you would like to retcon your attack to aim at the escaping Gnoll since he might do that, we can retcon your target, but the attack will still miss. You are 1 more movement from being able to reach DK!

Muireach strides forward, ignoring the presence of the hound. His eyes are focused on the powerful gnoll running towards town and faintly glow the same color as Summer’s. He dares turn his back? He dares spit upon the honor of the once and future king! Muireach extends a hand outward and clenches it as he casts Hold Person (DC 15 Wis Save), “You leave by my command, and mine alone.”

Luthok looks to the escaping gnoll as it wooshes by, then to Dyoken and back to the escaping gnoll again. "Hey! No stragglers! Dyoken you'll just have to not die on your own." With a wave of his hand the underbrush around the gnoll starts twisting and turning as the Entangle (Save: 13) takes it's effect. The affected area starts just a little closer to Luthok than the powerful gnoll is and starts covering the ground in front of the gnoll and the way it was heading. 

(Just so everyone knows the Powerful Gnoll passed with a 17 on the die.)

Quote from BDaddLy >>

Dyoken roars with fury, entering a Rage as he closes the distance, meeting the beast along the way. ...

 (I don't mind taking the extra damage. RAW the rage and Attack both occur on my turn, so they either get resisted with advantage or neither. I just read your description and thought you were being generous. =P )

Dyoken shoves the Spear Gnoll flat on its rear, but holding firmly to its leg (Athletics: 26), and glares at it. "Submit to your new king!" He spits (Intimidation: 19).

Merrick fires an arrow at the hellhound from the safety of the forest before ducking back into the treeline.

Merrick's arrow finds purchase in the center of the hound's head. Magma-like blood begins to pour from the wound as the beast falls over dead! Thankfully, it's raining.

Muireach shouts at the Powerful Gnoll who continues to run away. A loud thundercrack seems to have drowned out the king's very important order!

Mercy throws her weapon to the ground quickly and pulls out a longbow. Through gritted teeth and rain pouring down her horns toward her face, she flings an arrow at the Powerful Gnoll hoping to kill it before it can escape! However, her arrow soars just over the gnoll's head.

The Spear Gnoll, grappled, attempts to bite DK!

(Attack on Dyoken! Attack: 15 Damage: 3 piercing)

Bow Gnoll, seeing that DK grabbed onto its ally growls and keeps its bow trained on DK. It seems to be preparing an action.

Powerful Gnoll continues to run and run and run. You feel like if you don't chase him or stop him now, he WILL get away. He is two dashes from Luthok, Vivi, and Mercy.

Vivi continues to [Ready] attack the Bow Gnoll if it does indeed fire on DK.

DK successfully gets the gnoll downed. It howls in agony.

Bow Gnoll is about to shoot DK! Vivi senses this and yanks her scythe aggressively at the gnolls' neck. His head, well, falls to the ground and soon his body follows.

Luthok reaches out and causes the earth itself to bow to his will, but the Powerful Gnoll seems to excited to be stopped! He pulls free of the veins and continues his run toward the monster-infested village!

Muireach releases another pulse of commanding presence as he steps forward another 30 feet, “I SAID HEEL!” Hold Person once more, DC 15!

Seeing that he won’t reach the gnoll in time, Muireach starts sprinting and leaps into the air releasing the enchantment midair, 8!

However, failing abysmally at that, the gods give him the opportunity to just shoot, which he does. Eldritch Blast! Attack: 11 Damage: 4 force damage 

Dyoken decides he might as well follow up on the dog gumming on his arm and pokes it with his blade, hitting 22 for 15 'Sneak' damage.

He also hauls his quarry with him as he moves toward the fleeing mutt, but he won't manage much ground (15 feet).

Luthok curses as the gnoll tears through his vines. He does his best to keep up with it, moving another 25 ft in his pursuit. "Not ready to be leashed? How about being put in a kennel then?" The dwarf shouts as he casts Wall of Thorns creating a circle around the straggler. 

Damage (if he decides to move through the wall): 28 Save: 13 Dex

Still from the safety of the trees, Merrick unleashes another arrow at the powerful knoll, then pops down under a log.

Merrick fires his arrow, and it hits true, striking the Powerful Gnoll on the back. It gasps from the shock of the attack, the effects of Muireach's charm washing away with the rain.

Muireach, unfortunately, attempts his jump toward the gnoll, hoping to command it to stop - but he falls short. Baring that, he attempts an attack of his own, which doesn't land.

Dyoken cuts up the gnoll in his arms, and he feels the life leave his meatshield. 

Luthok manages to completely encircle the Powerful Gnoll. PG seems frenzied. He attempts to claw his way through the thorns, but alas, he is scratched up by the attempt. He seems fully trapped. The old dwarf understands they have 10 minutes to surround the bastard before he can attempt to flee again. Should be easy enough to accomplish.

Mercy and Vivi approach PG carefully. 

It would seem that combat is over for now.

- Everyone gained 350 EXP! -

Dyoken tosses his shield aside, takes a deep breathe, and lets his Rage subside, as he steps up to the wall with Luthok.

Muireach follows after getting to his feet and levels the blade at the gnoll’s throat, pressing in slightly.

Merrick tends to his wounds, gasping in pain as he touches the burns

"So we'll gang up on him now right? No escape and certain death?" Luthok looks straight at the wall of thorns in front of them. 

So you have the gnoll prisoner. What would you like to do? Mercy informs you all that she speaks gnoll, so she can easily translate anything this one says.

Let’s ask them what their plan is.
