the two wakey elk stand up (uses half movement so they can't charge anyone) move behind and try to antlerize the gnoll Raven just swung at:

19 if hit 4 and  15 if hit 5

((since elk are last, if they get to attack right after the gnolls maybe R does get bonus damage, if 14 hits))

Del will  whisper dissonantly at the same, or the next swordsgnoll if the first falls first 8 psychic damage, half on DC 15 WIS save, on failed save use reaction to move away from Del

'Cause what you see you might not get - And we can bet so don't you get souped yet

He will move the 5 feet or so to the next two elk - Possibly getting partial cover from the archers? If he has a chance to wake them great, but in any case be ready to cut some words if a gnoll attack seems too good

Quentin, running out of spells, just shoots a simply fire bolt at the gnoll that shot at him.

Firebolt: Attack: 16 Damage: 5

Raven's attack puts the gnoll at death's door, and the elk opens it for him.

The last sword gnoll struggles not to listen to Del's whispers-- Wis save 21

Gnoll 7 attempts to resist Elwin's ice (Con save 14 ) only to be scorched by Quentin's fire.

Ignoring the ongoing battle, Eggric tosses aside the saucepan he was wearing on his head and pulls the fierce-looking helmet off the gnoll lord he finished off, plunking it on his noggin. Goblins have a large head-to-body ratio, so it isn't quite as oversized as you would think. Still, it makes him look like a bobblehead.  "Mine!" Eggric says happily.  The word echoes in the empty hollows of the helmet.

Mindartis barely touched the floor before he had 8 hp back again.  Now he needs to decide what to do with them.

LOL, forgot to move Quentin to the table...

Movement: Half to Stand up, 20 feet to the pair of gnoll closest to him.

Bonus Action: Rage, Wild Suge: 8
Result: A beam of brilliant light lances from your chest in a 5-foot-wide, 60-foot-long line. Each creature in the line must succeed on a Constitution saving throw or take 2d8 radiant damage and be blinded until the start of your next turn. DC 14 con save or take 4 Radiant Damage

Action: Greatsword Attacks
Attack: 14 Damage: 13
Attack: 27 Damage: 15

Oops did a bad thing i'll reroll the attacks

Mindartis pulls himself to his feet and looks around and grabs his sword, the fury in his ears starting to ring again as he rushes at the gnoll closest to him. He attacks it.

Attack: 13 Damage: 10
Attack: 29 Damage: 24

Mindartis not only wipes out the last sword gnoll, but takes out the nearest archer as well.

Fearful of the barbarian, whose mighty black blade shredded their hag bosses and who they saw come back from the (mostly) dead, the last three archers concentrate their fire on him:

Gnoll 5 Attack: 18 Damage: 6

Gnoll 5 Attack: 9 Damage: 6

Gnoll 5 Attack: 17 Damage: 9

The party is up again.

Del reacts by using Cutting words to reduce the best shot by 5

The two elk charge the furthest east archer:  21 if hit it takes 14 and   19 if hit it takes 15 (that has the charge damage built in) if hit DC 13 STR save or knocked prone

Did Del get a chance to wake up any other(s)?

Yep, you woke up two more elk. And none of the arrows hit Mindartis, thanks to you.

And Archer 7 is done, only 5 and 6 left. They do not look like they have any intention of surrendering.

The warlock was on his target within seconds.

With a quick curse that sounded more like an elongated roar, Elwin quickly speared his weapon twice at the gnoll archer.

Same target, the gnoll archer right above the "A"

MOVE: Close to within melee range of the target
BONUS: Cast Hexblade's Curse on the target; crit on 19-20, plus +3 damage, plus +8 HP if it dies
ACTION: Two spear attacks toward target
 - First spear attack: 8, Damage incl. crits: 8
 - Second spear attack: 14, Damage incl. crits: 11

The other two elk stand up, so no one in charge range, just gore the nearest gnoll (I think #5, westernmost)  

18 if hit it takes 4  and  16 if hit it takes 9

Del backs out of the way in case anyone wants to get through (10 feet SW) and  mocks that same gnoll #5 (DC15 WIS save or 5 psychic plus disadvantage on next attack), fitting it into the refrain:

I'm tellin' all y'all it's a sabotage  -  Slander of thy mother's womb  -  tellin' all y'all it's a sabotage

(Elwin, that's #7 and he's dead.  You can go to the next, #6)

Elwin makes a fierce attack at Archer 6, and a couple of elk make not-too-effective attacks at #5.  Both archers are wounded, neither is dead yet.

Eggric searches Gnoll Lord 2 for other loot. 8 "WOOT!" he says, holding up a bag of coins.

Raven and Mindartis still have attacks.

((also Quentin gets an action, and Del's not-very-viscous mockery on Archer 5))

(Oops, yes, Quentin, too.

Mockery noted: #5 is still alive and snarling.)

(( Mind if I roll a Perception check to see if Elwin notices Eggric looting before the fight is even finished? He wouldn't take kindly to it.... Perception: 14 ))

bRaven moves to attack the closest of the archers...

Attack: 10 Damage: 7

Sneak attack: 4

Elwin notices: Eggric is not being at all subtle about it. No perception roll even needed.

Raven misses her attack.

Quentin releases another Firebolt at the weakest looking up enemy. 

Firebolt: Attack: 16 Damage: 13

Movement: Down to the gnoll directly below him.

Action: Greatsword Attacks
Attack: 25 Damage: 14
Attack: 20 Damage: 19

Bonus Action: N/A

Mindartis charges down to the Gnoll directly below him and swings his greatsword at him.

And with those last fierce attacks by Quentin and Mindartis, the last of the enemies is defeated.  Victory is yours!
