Gnoll A runs under the foliage of a nearby tree to get to the bugbear he sees and raising his spear with both hands he aims to plunge it in Lanky's chest.

Attack: 16 Damage: 10

Gnoll B decides that is a good idea and runs down to attack the elf nearest him, trying to use his spear on Remi.

Attack: 17 Damage: 3

Gnoll C stays where he is and looses an arrow at Remi.

Attack: 23 Damage: 8

Gnoll D also fires an arrow at Remi as he is the only one he can clearly see

Attack: 13 Damage: 8

Landee, seeing the crazed gnolls, gets scared and tries to hide under the fallen log beside Remi.  Sitting with his back to the log he buries his face into his knees and starts rocking, Remi and Elirion can hear a small moan coming from him.

The chief, being too far away to inflict any damage rushes into the frey, dashing his way to Elirion and E'Lar.

Tastie & Lanky are up!  Remi & E'Lar are next

 Sorry, forgot to move Landee - he's to the right of Remi

Tastie

Tastie smells the gnolls early as her spear warns her, the odor of soiled small clothes assails her senses. She wrinkles up her nose in disgust. Bonus action mage armor. 
Spying the gnoll to the north and the gnoll leader to the west, her eyes begin to cloud over. The familiar smell of ozone comforts her and hopefully causes dread in these offensive creatures. 
Waving her arms in familiar gestures and speaking a sharp phrase, she casts witch bolt at both of them. 
Attack: 24 Damage: 20. 
Note to DM: 2nd level. She is insistent on this attack and if the roll misses she will use other features to try to get it to hit. 

For clarification targets are A to the north and the chief to the west. 

Lanky growls at the Gnoll attacking him and swings at it twice. 
Attack: 26 Damage: 6 

Attack: 12 Damage: 11 

Remi feels the spear slice him along his side, but he is able to uncannily dodge the full blow of the arrow shot at him from the other gnoll, only taking half of the damage.  He shouts out “I’ve got it, thank you!” to Gabin.  

He pulls out his short swords and attacks the gnoll in front of him, gnoll B.  If he goes down, he will turn his attack to the gnoll leader to the south of him.  

Short sword 1 : Attack: 24 Damage: 5 

Short sword 2 : Attack: 22 Damage: 9 

Sneak attack damage :  14 

When gnoll B attacks Remi, he takes 3 points of psychic damage due to Gabin’s Rebuke of the Talisman and is pushed back 10 ft.  Remi closes the distance to hit him with his first short sword.  

(The sneak attack damage is applied to Gnoll B, since no one else is within 5 ft and Remi uses Rakish Audacity to hit him with that.  So 3 + 19 damage to Gnoll B and if he goes down he uses his second swing to attack the gnoll leader to the south).

E'lar scrambles to his feet, gathering up his club as he calls out to nature. His form seems to blur a moment as multiple figures step out of him and circle at a distance of 15 ft. They are not elven, however, instead appearing as spectral green tree people each gripping a club in one hand and the other arm terminating in a wooden shield. They pass right through his friends, but converge on any gnolls.

He grabs his own shield from the ground next to him and prepares to put it on. 

((If there is a second gnoll within the radius of the spell that he can get without leaving the leader's threatened range, he'll circle there, but I think the one to the north (B) got blasted back? Should be able to get A perhaps? Their speed is halved, and will have to make a DC 16 WIS save at the start of their turns if they start in the affected area, or as they enter it if any others join the party.))

The bolt Tastie conjures out of the sky breaks in two and strikes at both Gnoll A and the Chief, almost knocking A to the ground.  Lanky finishes A off with his first swing, his second finding air as the gnoll hits the ground.

Remi, empowered by the talisman strikes his foe with vengeance and with that last 3 points of damage, manage to kill it with his first strike.  He then spins and connects with the Chief.

Pack Leader A seeing the fight go as it is, incites rampage on the chief and the chief attacks Remi, he goes to bite the elf, aiming for the tattoo of the middle finger on his arm:

Attack: 18 Damage: 6

Continuing...  (Sorry, just realized Remi is too far away, that went towards Elirion - didn't hit though)

The Chief misses and growls at Remi.

The green tree people suddenly arrive joining the party and encircling the chief gnoll.  The chief is looking bloodied, and at the sight of the tree people he is rethinking his lot in life.

Pack Leader B uses his reaction to also incite rampage on the chief and this time the chief attacks E'Lar

Attack: 19 Damage: 6

Continuing...

The chief's teeth connect with the elf's arm and E'Lar also has to make a CON save of 12 or take 7 poison damage.

Pack leader A moves in on Remi and attacks with his glaive

Attack: 16 Damage: 13

Attack: 17 Damage: 13

Pack leader B heads towards the circle of tree people and draws his long bow, shoots his arrows at E'Lar

Attack: 17 Damage: 9

Attack: 8 Damage: 4

ROUND 2

Elirion & Gabin are up!

E'lar Con Save vs Poison: 21
Concentration: 17

((Oof... and just like that, his 3rd level spell does nothing before he loses hold of it. Spirit guardians are gone and he takes 6 poison.))

Gabin fires off two more eldritch blasts at Pack leader A (Or if the first one kills him, the second will go for the other pack leader.) Gabin then pulls out his mace and moves to stand next to Elirion and E'lar, within reach of the bugbear chieftain.

Attack: 20 Damage: 6 

Attack: 20 Damage: 12 

Gabin's blasts pack their punch and lay into Pack leader A.  (Do these move him at all?)

(Yeah, 20 feet total)

The look of consternation on Elirion's face from the misfire of her spell turns to frustration and annoyance as the chief runs up next to her. She frowns, glances at him briefly, then moves around him to get a clear line to the remaining three of her previous targets.

"Let's see if I can get this right," she says. Once more, this time a little slower, and with a great deal more care, flames coalesce around her hands, compress and then the small point of intense light flies into the clearing before bursting into a roiling mass of flames.

21

The gnolls burst into flames and die on the spot.  The pack leader is a bit more dextrous and avoids most of the flames, but did get licked on the side of his face and isn't looking too healthy in general.

Landee continues to cower, trying to wedge his body between Remi and the fallen tree as much as possible.

The Chief, surrounded by everyone is happy that the tree people are gone, but turns to attack the elf that created the fireball and eliminated the rest of his low level gnolls.  He first leans in to bite Elirion:

Attack: 6 Damage: 8

(If it hits, make CON save of 12 or take 10 poison damage)

Then attacks her with his claws,

Attack: 21 Damage: 4

Attack: 14 Damage: 4

Tastie & Lanky are up! Remi & E'Lar are next

updated map:

(couldn't get rid of the ring on this computer - no idea why, so ignore it)

Lanky moves 5’ to get within grabbing distance and tries to grapple the captian with his noodley arms twice.
18

12

If successful: lanky will then speak the command word for his boots and fly up.

else: lanky moves closer to the captian.
