Ordrag CON save: 19

     OwImp is continuing to return to Polly, having found nothing in his explorations.  Probably back after another couple rounds...

     The Gnombies, who aren’t stunned, all just shuffle their way towards Polly.  Possibly 1&3 could shamble into range to attack but I’m assuming  the Vrock is above ground level and above their range? 

     Polly considers her actions, for the briefest of moments.  She has more powerful tools she could tap into if she wanted to release here shambling horde...  Not yet, she decides, relying once more on her Eldritch Blasts vs Vrock...

Blast 1 Attack: 16 Damage: 8

Blast 2 Attack: 19 Damage: 13

Blast 3 Attack: 26 Damage: 6

Adray con save 16

Terrible screech did not destroy Brutus's sensors, nor did it affect Adray or Ordrag, but one of the gnolls was caught in the sound waves and now stood frozen with the paws up to his ears. 

Gnombies (those that could move after the attack), lumbered towards Polly, (number five stopped in front of a burning bush - it can get inside, since self-preservation was removed from his mind, but the bush was a legitimate obstacle).

Big ugly dull-witted hybrid of humanoid and vulture turned out to be not that tough, or at least not that hard to hit - every blast found it's target, not killing the beast, though. Small attentive full of hate eyes focused on Polly now.

The gnolls down on the road, though attacked and without a leader, were still fighting:

Number one tried to reach Ordrag with its spear: Attack: 16 Damage: 3

while Six went towards his formal comrade and attacked gnomby 1 in the same manner:  Attack: 19 Damage: 5 breaking a few ribs of the zombie.

Two continued to fight the unicorn: Attack: 16 Damage: 9

Mooncolor's skin was pierced again, but the unicorn ignored the pain and immediately retaliated:

Attack: 9 Damage: 8

Attack: 13 Damage: 14

The gnoll dodged and duck avoiding both hooves and horn, though.

 Choir!

(Choir moved last turn, she should actually be just southeast of Fran now.)

Choir moves even closer to the Vroock and casts Thunderwave, trying to aim it so that her friends aren't hurt. (Level 5, 21 thunder damage and knocked prone if failed save, con save DC17 for half damage)

Sorry for both confusions, I knew I forgot to move someone! Also, did not said how high the Vrock is in the air (30ft), Thunderwave should originate from a caster, 15ft would not be enough to get the demon.

(Okay, change the spell to Shatter and everything else should be the same, except no getting knocked prone.)

Vrock save: 19

The air thickened around the demon and for a moment its silhouette blurred, but then became clear again and the creature made an irritated noise.

 Round 4

Fran Brutus Ordrag Adray

(Vrock is still in the air, gnoll 4 is stunned)

Adray looks over at Ordrag for a moment and then back up to the Vrock.  "Can you clean up these one, I'm gonna try and ground that gnoll," Adray says to him.

With that, Adray takes a breath, aligns his ki and unfurls spectral dragon wings.  He then flies into the air and flies straight above the Vrock and goes down with two heavy kicks trying to force the creature down.

Move: step of the wind 1 ki point to gain 50 feet of movement for bonus action, wings unfurled feature grants flight speed when using step of the wind

Action 2 attacks at Vrock

Attack: 15 Damage: 10

Attack: 13 Damage: 11

Fran would step in closer to be with Choir and Mooncolour. She’d reload her crossbow, prepping her bolt with a little sprinkle of ‘luck’. Aiming up at the Vrock, she’d watch as Adray unfurled his wings and took to the air. She’d focus her shot on the Vrock.

Attack 1: 13 Damage: 7 
Attack 2: 18 Damage: 7 

BA: Branding Smite on hit Damage: 10 and it glows

Brutus would keep with Ordrag, nipping at the gnolls heals to provide disadvantage against the fighter. 

Ordrag grunts and nods to Adray, then moves to position himself between the two gnolls. Taking advantage of the vrock's unexpectedly helpful screech, Ordrag concentrates his attacks first on the stunned gnoll before returning his attention to the other...

Summary:

Longsword#1 21 (30 if adv)  10 slashing (24 with crit)
Longsword#2 29 (adv moot) 23 slashing
Longsword#3 17 (28 if adv)  13 slashing
Warhammer    12 (13 if adv)  10 bludgeoning

Ordrag finished the stunned gnoll with one mighty slash, turned around and cut off the head of another, not even stopping to ketch his breath he made a few steps and finished off already wounded number six.

Meanwhile, Fran's dagger hit the flying monster and it lit up like a candle, but then Adray did something unexpected - he flew to the demon to deliver his strikes. If monster was surprised, it recovered quickly - huge wings flapped seemingly lazy, keeping the monster afloat, the demon shook Adray off, and, though obviously heavy wounded, attacked. A grey choking cloud spread from it's wings, covering the battlefield:

Polly, Choir, Adray, and gnombies 1, 3, 5 - a DC 14 Constitution saving throw or become poisoned and take 3 poison damage at the start of each turns.

Gnoll 2: 15

 Polly!

Polly Con save: 19

     Gnombies 1, 3 & 5 will all shamble towards the Vrock and slam against it, if it is within range. They're gnombies,  they're immune to poison and unbothered by the choking cloud.

Gn1 Attack: 21 Damage: 9

Gn3 Attack: 21 Damage: 11

Gn5 Attack: 25 Damage: 6

     Polly considers backing out of the cloud and putting some separation between herself and the Vrock but she worries if the turns her back to the thing it may strike out at her... She considers her options but still finds the Gnombies useful so resorts once more to her Eldritch Blasts...

EBlast 1 Attack: 20 Damage: 7

EBlast 2 Attack: 26 Damage: 14

EBlast 3 Attack: 15 Damage: 9

(True to that - the dead do not breath)

Vrock is still fyilng, though, so, all the gnombies can do it to come closer or attack the last gnoll (number 2) if so - it's dead.

And again, the blasts did not miss, every single one of them hit the creature, but bleeding and assaulted by every means huge demon was still in the air, probably unable to find it's way out.

Choir!  (Gnoll 2 is probably down - Polly, confirm, the Vrock is still with us, flying)

((I had to double check if they were immune or resistant, so no worries there...  And yeah, if Vrock is too high for them to even club at, they'd shamble over to what they could attack.))

Only critically wounded Vrock is on the map now for Choir to deal with!

(Sorry for the absence, stuff was going on!)

Choir takes another shot of Sacred Flame at the vrock! 21 damage, DC17 Dex save to avoid.

(NP!)  Vrock save: 22

The radiant light was not even that blinding or massive - a mere sparkle in the smoke clouds, and yet the demon dropped down into the puddle of his own ichor, splashing it around.

At that very moment a wild, hideous laugh pierced the air and cut through the din of battle. A giant gnoll covered in matted, bloodstained fur and swinging a three-headed flail charges out of the haze from the west. With gore dripping from his red maw, open in a violent laugh, he ran towards the party.

Initiative: 21

If not for that laugh, his attack could be truly devastating - the creature looked like gnoll's god himself. But you had time to react and when the huge demon reached the party, at least some of you could properly greet him.

New round count, old initiative order:

 Round 1

Fran Brutus Ordrag Adray, Polly!

((Hold this until after Adray, but so much easier to do from home then from at work in morning on the cell phone...))

     When Gnombies Attack!  They may have had reverence for this thing if they were living gnolls but as undead gnombies they just saw brains for the eating!  All of the Gnombies shuffle up to the intruding Gnoll God, all but one reaching it and slamming themselves into it...

Gn2 Attack: 14 Damage: Unable to parse dice roll.

Gn3 Attack: 27 Damage: 10

Gn4 Attack: 14 Damage: 8

Gn5 Attack: 18 Damage: 9

     Polly was happy to have some distance between here and this new demon, and happily added to it.  Flying in a northeasterly direction, Polly continued to send blast after Eldritch blast into this seemingly endless parade of demons.  "How did this memory end, anyway??" She shouts out while blasting.  "Is there a quicker way of making this dream end?"

First Eldritch Blast Attack: 13 Damage: 12

Second Eldritch Blast Attack: 11 Damage: 8

Third Eldritch Blast Attack: 14 Damage: 6

"Wake up, sleepyhead?" Choir shouts back.
