Two disgusting, demonic creatures loom into view.  They resemble giant hybrids of humanoid and vulture, their gnarled, bestial bodies and broad wings stinking of offal and worse.  Neither lands on the Golden Empress, rather they hover nearby, eyeing the ship and its occupants with covetous, hungry eyes.  All of you feel in your minds, rather than hear with your ears, the greedy voices....

Mine!

Mine!

Mine!

Captain Neck grimaces as the throws a level and the sound of the engines grow quiet.  "We can't just stop for long.  The current is still taking us downriver and the collapsed bridge isn't far ahead.  I will need to be able to maneuver.  Your men will need to wrap this up fast!"

While Cosette is hiding in the shadows on the second deck, Raqisat finds his own hiding place under the stairs and Aubrey ducks below the upper railing.  [All three start this round hidden.]  Grugga, I need a stealth check if you want to remain hidden.

The Vrock at the front of the ship lazily raises a wing to turn out of the path of Grugga's exploding crystal.  It flaps both its wings to maintain its distance 10' above the lower deck.  It locks its eyes on Leelan, ignoring the two constructs for now.

The Vrock at the back of the ship hovers at the level of the top deck, just off the starboard side.  It seems to grin at Rohuzar, inviting him to approach.

[Vrock tokens on the map are clear on the level of the ship equal to their vertical position, slightly greyed out on other levels.]

ROUND ONE!

1. Rohuzar
2. Vrocks
3. Everybody Else!

     “Yours?” Raqisat calls out from cover.  “Which one of yours?  Shouldn’t you two sort this out between yourselves first?”

Rohuzar charges the Vrock near him, laying about with broad chops of his silver sword before raising his shield up

Attack: 10 Damage: 12 

Attack: 15 Damage: 12 

Rohuzar's first strike fails to connect, but his second finds its target, slashing the demonic bird and sending feathers and black blood down to the river below.

Rohuzar:

 The creature flies just overtop of Rohuzar (without leaving his reach or inviting an AOO) flying 5' above the middle of the ship's top deck.  It emits a horrifying screech that Rohuzar must try to endure.  Rohuzar must succeed on a DC 14 Constitution saving throw or be stunned until the end of the Vrock's next turn.

The other Vrock near the front of the ship cocks its head to look at Raqisat, the latter having given up his hidden position in favor of a quip.  It flies forward until it is above Leelan's position... and then shakes itself and its dark feathers.  That foul, acrid stench from earlier is back... now overpowering.  A 15­-foot­-radius cloud of toxic spores extends out from the vrock. The spores spread around corners.  Leelan, Raqisat and Grugga must each succeed on a DC 14 Constitution saving throw or become poisoned. While poisoned in this way, a target takes 3 poison damage at the start of each of its turns.  A target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

The Vrock then flaps back to its original position, 10' above the lower deck and just off the starboard side.  As it moves away, Raqisat can take an AOO if he has his whip equipped (10' reach), if he chooses to.

Everyone else is up, then Rohuzar to start the next round before the Vrocks go again.

Aubrey peeks out from cover and calls upon the mystic powers of his talisman to send two golden beams of eldritch crackling force towards the screeching winged creature, then diving back into full cover at the southwest corner of the bridge.

Eldritch Blast: 14 Another roll if advantage due to being hidden: 12 Force: 9
Eldritch Blast: 23 Another roll if advantage due to being hidden: 10 Force: 13

Leelan’s CON save: 11

The smell released by the creature makes Leelan feel nauseous and ill. Being out in the open, he tries to look for a more advantageous position. He runs to the barrel south of his position, behind Grugga’s constructs. He then conjure an icy arrow that he attempts to shoot at the creature despite his condition.

Action: ray of frost (if hit, target’s movement speed is reduced by 10 feet)
Attack: 20 Damage: 6

He then focuses his senses on the monster, looking for weak points to exploit.

Bonus action: Slayer’s Prey

End of turn Con Save: 3 

Con save: 12 (rolled in game log)

The noxious wave washes over Grugga and the Orc instantly begins retching. He drops to his knees for a moment, eyes watering and nose running, before he manages to momentarily compose himself. He rushes out to the deck, ordering Zap to his side. ((let's say, Grugga will be 4 squares left of where Zap is now, and Zap will be one square to the right of him.)) Grugga uses what little breath he can muster to issue a challenge to the beast, "Here beast! Here and die!"

Grugga will use his action to hold an attack.

Attack: 15

Damage: 11 magical slashing

Zap will use its Deflect Attack reaction to impose disadvantage on an attack against Grugga IF the Vrock is within 5 feet of Zap. Zap will use its action to dodge.

Grugga takes 3 poison damage

Con save at end of turn: 16 (rolled in game log)

After throwing down the gage on the bird monster, Grugga promptly vomits onto the ship deck and he looks much better.

Raqisat Con Save:  3+5 for 8

    No opportunity attack for Raqisat as he was intended to hidden with two daggers not realizing his voice would be enough to give his location away...  Regardless, he is distracted by his watering eyes and his lunch's sudden decision to try to mount a comeback and escape one way or another.  He is too distracted to be that quick on the attack.  But he does manage to step out into the open and up into range of the creature before doing his best to launch a couple of daggers at it.  ((3 poison Dam taken to start round...))

Dagger 1:  17 or 24 to hit and 4 damage

Bonus Action Dagger:  23 or 24 to hit and 7 damage

     The daggers go better than Raqisat expects, considering the wave of ick which washed over him.  As he draws a whip and a dagger to be prepared for whatever comes next he also tries to draw upon his own fortitude to fight back the feeling...((End of round Con Save... Also an 8))

Aubrey unleashes twin beams of force at the Vrock threatening Rohuzar.  One of the beams just misses, while the other slams into the bird-fiend, sending feathers flying.

Leelan hits the Vrock at the front of the ship with his  ray of frost, an icy sheen forming over the demon's wings.

Both of Raqisat's daggers connect.

Raqisat:

[Botting Cosette for this round... based on OOC note from another game I think she is away all weekend...]

Still hidden, Cosette creeps along the second deck until she has a clear view of the creature flying just off the prow.  Its a disgusting fiend, and she can smell its foulness (though the poison does not implicate her).  She raises her light crossbow and fires a bolt from hiding.

Attack: 21 Damage: Unable to parse dice roll.

She offers encouragement to Raqisat.  [As a bonus action, she grants 1d8 Bardic Inspiration.]

Rohuzar is up for Round 2.  We need that DC 14 CON save to see if he is stunned  or not.

Rohuzar con save 22 

Rohuzar continues attacking, although he sees the lesser effect. 

Attack: 26 Damage: Unable to parse dice roll. 

Attack: 26 Damage: 17 

He then brings his shield back up to be ready to fend off the creature

Once again, Rohuzar connects on one of two attacks.  This one is a heavy blow, but yet again he is denied the satisfaction of doing as much damage as he should have expected.

The Vrock engaged with Rohuzar strikes out with its dirty beak at him.

Attack: 19 Damage: 20

Then it flaps its wings hard and kicks out with its lower legs, attempting to shove Rohuzar over the top deck railing and down to the second deck below.  Rohuzar, make a contest roll using either Athletics or Acrobatics against DC 17.  On a success, you stand your ground.  On a failure, you are shoved backward over the railing and fall to the second deck walkway outside the rooms on the starboard side, taking 6 bludgeoning damage and landing prone.

[What this Vrock does with its movement depends on whether it is successful in shoving Rohuzar or not...]

...

The Vrock at the front of the ship seems to answer Grugga's challenge, flapping its large wings and coming to a stop just overtop of Grugga (within 5' of Grugga and Leelan and within 10' of Raqisat and 15' of Cosette).  Instead of attacking, however, it emits a horrifying screech that threatens to incapacitate all those nearby.  Grugga, Leelan, Raqisat and Cosette must each succeed on a DC 14 Constitution saving throw or be stunned until the end of the Vrock's next turn.

[What this Vrock does with the remainder of its movement depends on who passes their saves...]

Raqisat Con save:  19+5 for 24 so Raqisat is merely poisoned, not stunned as well.

Leelan Con Save (for stun): 3

Leelan takes another 3 points of poison damage at the start of his turn.

Leelan is stunned and cannot act this turn.

Leelan Con Save (for poison at the end of his turn):8

"Son of a biscuit-" Cosette's unable to cover her sensitive ears in time. Now they're ringing so loud, she feels deep vertigo.

(Cosette con save on Char sheet: 13 vs DC14. She fails and is stunned.)

Con save: 15 (rolled in game log)

Grugga is happy to see that his provocation has the desired effect... but less so when the creature lets out an ear-piercing screech that threatens to burst the Orc's eardrums. Nonetheless, despite an immediate ringing headache, the Orc perseveres and prepares to strike with his readied attack.

[Botting the Athletics contest for Rohuzar to advance the round... 17 ]

Perhaps caught off guard by the demon's shift in tactics, Rohuzar is sent toppling over the rail, landing hard on the second deck below.  The Vrock then lands on the top deck just outside the closed door to the bridge.  It grips the wood-framed bridge building in both hands.

Aubrey, you pick up something of the telepathic command it gives to Captain Neck.  It is not the subtle mind-to-mind communication you are familiar with; more like a megaphone of thought blasted outward at a target.

 At the front of the ship, the Vrock there observes who appears stunned and who doesn't.  It holds its position, hovering just above Grugga and Leelan.

Grugga's held attack indeed goes off.  He strikes the monster and his imbued weapon cuts true.  The demon-bird seems more annoyed than wounded, however.

Round Two:

1. Rohuzar (prone)
2. Vrocks
3. Everybody Else
   • Leelan (stunned;poisoned)
   • Aubrey
   • Grugga 
   • Raqisat (poisoned)
   • Cosette (stunned)

Aubrey moves to peek out from cover and again calls upon the mystic powers of his talisman to send two golden beams of eldritch crackling force towards the stinking bird-like creature, then stepping back into full cover at the southwest corner of the bridge.

Move a square to the south 
Eldritch Blast: 11 Force: 14
Eldritch Blast: 16 Force: 9

"Just stay put Captain Neck, this will be over soon." The young noble messages the captain. One way or the other he thinks to himself...

Knowledge to recognize the name Deinochlorodon: 10 (+3 if history, which I doubt ;-)
