As Rhayna moves up close to one of the goat-headed demons, it swings it's barbed tail at her...

Balezau#3 Reaction attack (from Ready action): Barbed Tail v Rhayna: Attack: 15 Damage: 13 piercing damage. If the attack hits, Rhayna must succeed on a DC 13 CON save against disease or become poisoned until the disease ends (and more, but we'll see what happens)...

From the far end of the cave the mysterious creature slowly comes into view. With the minotaur leading the way like an escort, a huge demon with burning eyes looms behind it, its mouth belching fire. In one hand it grips a gigantic sword which sparkles with lightning, and as it releases the leash from the minotaur's neck, the chain becomes a flaming whip. Those familiar enough with beings from the Abyss know this to be a Balor, a most fearsome demon. No sooner does the balor lurch into the cave than it spies the mortal beings for whom it has been hunting. Hungry for mortal flesh it spreads its wings and propels itself across the intervening space, landing right amongst the party, brandishing its fell weapons...

Longsword v Sekkar: Attack: 18 Damage: 24 slashing + 21 lightning damage

Whip v Kirin: Attack: 20 Damage: 13 slashing + 17 fire damage

---------------------------------------------------

Pax is next. Please start the turn by making a DC 13 CON save against the stink of the goat-demons or take 9 necrotic. Also Pax is blessed.

Round 1: Kleve 22, Bulezau 20, Kaylyn 17, Sekkar 15, Vizeran 15, Minotaurs 13, Rhayna 12, Balor 11, Pax 8, Modrons 7, Kirin 5, Dretches 3

MAP: (I left the dretches off this map, but they are still in the same location as before)

Pax Con Save vs DC 13 : 20 + 2

Gritting her teeth through the horrid wrenched stench, Pax, the dark shadows swirling about her, glances around at the myriad of enemies that have suddenly spilled out of the maze to surround her party. Her tactical mind takes over as she momentarily examines the battle, the demon taking a large part in her mind. 

First thing is first.  She holds out her hands, palms up, and clenches her fingers, and dark shadow roils up her legs and around her body...icy cold tendrils sparkling amidst the cloud of black. (4th level Armor of Agathys) She takes a step towards the Balor, trying to get close to the enemies. As she does so, she taps her boots together, triggering her Boots of Speed. 

She mutters to Kirin, "Get clear of the demons wizard, this is no place for you...."

The mighty balor seems to fill the cave, not so much with his physical size but with the raw intensity of his presence. But the group have not only seen worse than this, they have faced and survived it! The tridrone emits some bleeps and clicks that anyone could guess indicates consternation, but the mechanical creature is programmed to maintain its prime directive, and at the moment that is centered around its agreement with Rhayna. Seeing the bulezau menacing the cleric, the tridrone moves in to defend her, with the monodrones following along automatically.

Tridrone (3 javelin attacks) and Monodrones (1 javelin attack each) v Bulezau#3
Attack: 10 Damage: 7 piercing
Attack: 5 Damage: 5 piercing
Attack: 17 Damage: 2 piercing
Attack: 13 Damage: 3 piercing
Attack: 10 Damage: 3 piercing

Kirin is up next. Please start the turn by making a DC 13 CON save against the stink of the goat-demons or take 7 necrotic damage. Also Kirin is blessed.

Initiative: Kleve 22, Bulezau 20, Kaylyn 17, Sekkar 15, Vizeran 15, Minotaurs 13, Rhayna 12, Balor 11, Pax 8, Modrons 7, Kirin 5, Dretches 3

MAP:

Forgot CON saves for modrons (they are not exempt): T 21, M1 6, M2 5. Tridrone takes 6 necrotic (patches of rust begin to form).

Con save: 23

"Anyone want to deal with this guy? Anyone? Anyone? Dammit, talk to the hand," Kirin waves his hand to his side while staring the very very big demon, his hand appear to fall off him before growing bigger and bigger as he cast Bigby's Hand. With his right hand, he makes a crushing motion which Bigby's hand mimics on the Balor (Clenched Fist)

Attack: 30 Damage: 13  Force damage+ 2 from Blessed 

Blessed rolle for Con:  4

Kleve CON save: 16

The half-dozen dretches are slow but no less eager to join the fray and get their taste of mortal flesh. Although they lumber along as quickly as their short legs will carry them, they don't get close enough to anyone to cause any harm. Kleve remains magically out of view, although it is certain that he remains close to Vizeran, ready to protect him from any approaching demons.

The disease-ridden goat-headed bulezau abandon their deceptive ruse of luring others toward their barbed tails, and instead leap at the closest target...

Barbed Tail attacks:
B1 v Pax Attack: 9 Damage: 7
B2 v Sekkar Attack: 20 Damage: 5
B3 v M2 Attack: 21 Damage: 14
B4 v Rhayna Attack: 12 Damage: 13
B5 v Rhayna Attack: 24 Damage: 12

Any attacks that hit will require a DC 13 CON save to avoid becoming diseased (as well as concentration check for Rhayna)

Kaylyn and Sekkar are up next...

ROUND 2: Kleve 22, Bulezau 20, Kaylyn 17, Sekkar 15, Vizeran 15, Minotaurs 13, Rhayna 12, Balor 11, Pax 8, Modrons 7, Kirin 5, Dretches 3

MAP (edit: Modron #2 is down after that hit from the bulezau)

Con save:  9 + 2 (Bless)

Ok, this one hit and even left a mark.

The massive fiend was clearly the greatest threat and Kaylyn turned her attention to it.  Three beams of force energy blast the Balor.

Attack: 18 Damage: 15 + 3 Bless

Attack: 28 Damage: 13 + 4 Bless

Attack: 28 Damage: 11 + 3 Bless

She then calls upon the light and heals Kirin for 19 hp.  (BA Healing light)

Kaylyn also steps west 10 feet.

@Sekkar, you have Bardic Inspiration and can add 1d6 to that Con roll

(Ah! Added it on another character and felt like I was done :) Thanks! )

Inspiration for that roll: 1

Correction to the turn:

Sekkar was not dead just yet and could attack the annoying daemon (number 2 again):

BA: Zephyr Strike

Action1 : Attack: 25 Damage: 17
Action2 : Attack: 26 Damage: 11 + 4 (ZS) + 7 (SA), provided that was a hit.

Move: around Balor to be on the opposite side of it from Pax.

Sorry, I also meant to ask for a DC 13 CON save from Kaylyn and Sekkar at the start of their turn. This will be for everyone every turn as long as the bulezau demons are on the field and within 30 feet.

Also Rhayna needs a concentration check to maintain Bless. The only current roll in doubt is Kaylyn's first attack, but if it holds it might help the start-of-turn CON saves I mentioned.

I'm trying to put more information on the map, including current conditions. It might be hard to see, but for example Sekkar had a small musical note to indicate he had bardic inspiration, and now has a Zephyr icon.

No, I don't use Flanking, sorry. But Sekkar's first attack drops B2, so if you want to apply the second attack to another target (minotaur? balor? dretch?) then go ahead. I'll even let you decide with the advance knowledge of whatever happens next... (Vizeran is gonna cast a big one)  (DONE)

====================================

As Kaylyn back away from the balor, her shadows follow her, keeping her shrouded in darkness and also sending the adjacent Vizeran into deeper shadow, but briefly illuminating Kirin with healing. At least two of Kaylyn's blasts slam into the demon, seeming to punch through the powerful demon's hide.

Sekkar draws on his own nature-based magic and strikes two more swift blows, felling one of the festering bulezau and wounding the minotaur, before gliding like a shadow around the edge of the cavern to the other side of the balor.

Now more protected than ever, the drow mage holds his staff high and begins a powerful incantation. With a sudden, subtle, strange whiff of lavender, the wizard's spell radiates out, and the five demons in the heart of the battle are each drawn toward a small black mote, which seems to be sucking them out of existence...

Banishment at 8th level. CHA save: Balor 22, B112, B3 8,  B4 6,  B5 13

Screaming and flailing their tails and scraping the ground with their claws, the four goat-headed bulezau are dragged into the tiny black specks and disappear from view, leaving on the black motes hovering in the air. The balor however seems to almost swat the magical speck aside, although he turns and glares at the drow mage, probably blaming him for the two blasts that struck him as well.

The minotaurs are unaffected by the drow's magic, but the disappearance of the bulezau demons seems to spur them into more of a frenzy. One continues to attempt to gore Pax while the other charges at Rhayna...

M1 Reckless Gore v Pax: 12 Damage: 10 piercing

M2 Reckless Gore Charge v Rhayna: 21 Damage: 25 piercing, and on a hit make a DC 14 STR save or be pushed 10 feet back and knocked prone.
(Oops, forgot to roll with advantage for Reckless... 25)

=================================

Rhayna is up next! No need for a CON save at start of turn now, as the stink has left.

Round 2: Kleve 22, Bulezau 20, Kaylyn 17, Sekkar 15, Vizeran 15, Minotaurs 13, Rhayna 12, Balor 11, Pax 8, Modrons 7, Kirin 5, Dretches 3

MAP: (the last location of the bulezau is marked on the map, just in case they come back)

(If Sekkar can land the second attack on the minotaur 1, he does that! And another Con save: 20 + (hopefully) 4 (Bless))

(Sorry for the delay)

Rhayna CON Save: 11

Rhayna is hit, and drops her concentration on her spell. The appearance of the Balor is highly concerning, but the huge monstrosity right in front of her and the Modrons are her immediate concern.

Rhayna moves (NW 10ft then W 5ft) (she will take the OoA from M2), and as she moves she motions for the Modrons to follow her (hopefully ending north of Kaylyn). She then casts Confusion (east of M2, so it affect M2 and D4)

Con save 24 + 3 Bless

Pax looks to the huge beast next to her trying to gore her. She briefly considers casting another shield spell, but instead decides to let the creature slam its head into her shadows. Ice cold tendrils lash back at the creature. (20 cold damage). 

Her shadows weaken slightly.  (15 damage to her 'abjuration shield'. 5 hp's left + 20 temporary hp's armor of agathys.) 

Minotaur2 OA v Rhayna: Attack: 23 Damage: 12 
Minotaur2 WIS save v Confusion: 10
Dretch4 WIS save v Confusion: 9

Rhayna decides to risk the minotaur's horns first rather than have another spell fail. (adv roll: 8) The price is steep, with another painful gouge from the minotaur, but it pays off as her divine magic sends both the minotaur and one of the lesser demons into a daze.

Despite the irritation of Kirin's giant magic fist, the balor seems more annoyed by the attacks coming from the west. Seeing only the drow, it moves to get close enough to attack Vizeran with its whip, taking a passing swing at the bothersome lizardman on the way...

(Pax and Sekkar can both make an opportunity attack against the Balor)

Longsword v Sekkar: Attack: 16 Damage: 19 slashing + 14 lightning damage

Whip v Vizeran: Attack: 19 Damage: 11 slashing + 20 fire damage

Kleve concentration check: 21

The whip howls like the screams of the damned as it flies above the heads of the combatants, but with both the invisible Kleve and the shrouded Kaylyn in the way, the balor cannot hit the mage, and it roars in frustration. 

Pax is next

Round 2: Kleve 22, Bulezau 20, Kaylyn 17, Sekkar 15, Vizeran 15, Minotaurs 13, Rhayna 12, Balor 11, Pax 8, Modrons 7, Kirin 5, Dretches 3

MAP:

We are back into it! A little brief on the story telling perhaps, but I have a fair bit to catch up on.

One thing I overlooked is the Bigby's hand cast by Kirin. I'm still trying to interpret the spell rules, but it seems that it doesn't block movement, so I've allowed the balor to move through the space that I assume Kirin cast the hand in. I didn't put it on the map this time, but I'll put it in next posting.

Pax swings her drow tentacle rod at the massive demon creature as it tries to walk away from her. 

Attack: 27 Damage: 4

Attack: 21 Damage: 5

Attack: 13 Damage: 4

Then, glancing around at all the enemies, she casts Storm Sphere, yelling to Sekkar just before casting the spell, "Sorry Sekkar, get out of the sphere!"

A sphere of whirling air appears in the cave, stirring up dust and rocks and buffeting a huge area of enemies....flinging rocks into them and pushing them about. 

She points at the balor with her rod and there's a sudden spark of lightning in the sphere that blasts at the balor with a sharp crack.

Attack: 20 Damage: 20 lightning damage.

Difficult terrain for all creatures inside the sphere.  Each creature in the sphere must make a Strength DC 16 save or take 4 bludgeoning damage. Any creatures ending their turn in the sphere also must make a save or take 2d6 more bludgeoning damage. Disadvantage on listening perception checks inside the sphere. (forgot to apply bless to my attacks.  Don't think it matters, but for the AC 12 hit : 1.  If I need it for any other hit, go ahead and roll it for me or let me know and i'll roll.)

Sekkar AoO against the Balor: Attack: 20 Damage: 11

Strength DC 16 save: 11

Concentration (DC10): 15 (Sekkar loses Zephyr Strike)

STR saves: Balor 29, Dretch3 2, Dretch4 3, Dretch5 5, Tridrone 2, Minotaur2 23

(Bless is finished - sorry I didn't remove the markers)

The sudden underground storm batters the dretches as well as Sekkar and the tridrone, but the larger creatures seem to be able to weather it without fuss. However the action is getting a little too fierce for the modrons, and at Rhayna's protective advice, they move toward the edge of the cave...

Modron2 death save: 20

Kirin is next

Conditions:

Round 2: Kleve 22, Bulezau 20, Kaylyn 17, Sekkar 15, Vizeran 15, Minotaurs 13, Rhayna 12, Balor 11, Pax 8, Modrons 7, Kirin 5, Dretches 3

MAP: Spaces more than half-covered by the storm are difficult terrain

 Correction: All three modrons move (number two got back up!)

Looks the ball of lightning and thunder all other arcane events within as he selects his targets and non targets he moes a step to the left, "Back off," He uses bonus action for his Bigby's Hand to move to Balor's left between Balor and Rhyana and use  "Forceful Hand" command as he tried to push the Balor away from him.

Strength Check: 22

Depending on success of fail determines his next action.

If successful:

Kirin cast Cone of Cold from his staff of power trying to get the Balor, Minotaur and as many small guys as possible, sculpting it around Pax if needed then move towards the upper left corner/

Con Save: 17
Damage: 27 Cold Damage

If failed, Kirin disengages and move towards Rhyana, trying to get out of dodge.
