Careful of the opening of the gate Margret stops holding her hand up at the point where they still can't be seen from inside the compound whispering "let me check"  She enters Marco's senses to see if the orcs are still sleeping, and if the others are still where they were.

(Stopping at the point where Mehmen's  map says in the ooc:)

Dain restrains his urge to rush in, waiting for Margret to check the path for them. He has Sabastian out of sight, as he doesn't want so many familiars flitting about just now.

Otrov

The halfling will take out her poison and smear her bolts with the sticky substance [DM - Belladonna Poison].  Then she'll carefully move the dead orc and drag it over the trapdoor to slow down anything coming up through...

She will get The Prick ready for unpleasantness.  When Margret gives the signal, she will pop up and shoot the enemy present in the NE section below.

2 Otrov, as you try to move the dead body, it topples over and traps you under its weight, knocking the air out of your lungs. After a second of dizzy vision and vertigo, you recover and ungracefully work your way out from under the dead orc. You then start to drag the body to were you want it, but it feels like taking forever. You then dip three bolts in the spider poison and get into position to attack the two sleeping Orcs.

Everyone else, you hear something heavy fall over above you in the tower. Not loud, but you are close and paying attention to anything unusual. This is followed by silence and then something gets dragged across stone.

Otrov:

"What the heck was that?!?" Kala Whispers as she looks up to where the sounds came from "I sure hope that wasn't someone taking Otrov out"

"Best get on with this..." Dain says as he glances up at the tower. "No much we can do if someone took her out, but, if she be just getting into position, then it be best we be moving ourselves..." He glances to Margret for the go.

Otrov

The little halfling begins to move the giant orc corpse, but she fumbles a bit and the disgusting smelling body topples on top of her.  Racing for breath - but mostly hoping no one saw her in this position with this creature - she is able to slip out from under it.  She drags the flabby, sweaty body overtop the door in the top of the tower.  "Gross," she remarks before getting ready.  Hope that wasn't too loud, she thinks as she looks at the orc body.  She glances at the coiled and ready rope and nods.  Nothing for it now, she thinks to herself as she carefully slips a poisoned bolt in the feeder of The Prick.  

DM/All - ideally Otrov is looking to shoot the ones under her, not the sleepers - for the very reason you mentioned (disadv.).  Plus from where she is and where the description said the sleepers are, I don't think a shot like that is possible.  Would the ones below in the courtyard below give the same restrictions on the attack?  

"Pretty sure there'd be shouts of alarm if that happen, if not some cheering, little Rose." Biggz whispered back quietly while looking up as well. Regarding Dain after, the bugbear adds, "Probably get into the hole at least without attracting attention. But further than that might get a little sketchy with so many clankers." He chuckles softly, then too turn to Magret waiting for her return and give the go. Handaxes are drawn in the meantime gripped tightly for security.

Margret: If we are at the position at the map in the ooc: Margret hears the thump but not thru her own senses but Marco's, at the belfry She checks to see if the orcs are still sleeping and the others are still where they were at when last she spied. 

The bellfrey is most likely to far away for Marco to hear it.

Otrov, i mixed up who is where in my last reply. The for gambling Orcs are closest to you, and they are sitting, not prone. So for them you would roll with advantage for the first attack, wich gives you sneak attack.

Margret comes out of his senses "I don't think anything has changed are you guys ready?"

"Been saying so aint we?" Dain asks with a frown to Margret. "Just waiting on ye to be giving us the go..."

Margret tries to look and see where the sleeping orcs are thru the hole in the wall.

whispering "Now" She shoots 

 Attack: 9 Damage: 7

If they sit up action surge 

Attack: 19 Damage: 11

Initiative11 

As they wait, Dain would have cast armor of agathys At 2nd level.

As he gets the go he casts flaming sphere Slamming it into one of the orcs.

DC13 Dex save for half, or take 8 fire damage.

He then will move 30 feet towards his enemies, the staff of defense in-hand.

Initiative: 5

Biggz Initiative: 12.

Once the go is finally given Biggz readily slips around the corner just far enough to get sight on the gambling Orcs. As soon as he has it, swing he did the handaxe, pretending to cut down their still very far out out forms, sending a invisible wave of mystical lethargy their way.

Action: Cast Sleep at 1st Level over Gambling Orcs, affecting 30 worth of HP.

 Otrov

At Margret's signal, Otrov gets up and shoots one of the orc's playing dice below!

initiative - 22

 I always mess up rolls where Otrov is concerned.  Way of reminding myself: Due to Sharpshooter, she ignores disadvantage on ranged attacks.  For Assassinate, I am guessing they are not surprised.  Any attack on foe that hasn't acted yet is at advantage.

Otrov lines up one of the orcs below and let's the poisoned bolt fly:  adv. + sneak - Attack: 22 Damage: 12    IF it hits, orc must roll a CON save (DC11) or take 12 poison damage...

On Margarets command you all jump into action. Bigz reaches the corner of the guardhouse first, from here he casts his spell. One of the Orcs fall over and lands unconscious face first in the grass. A second Orc turns toward his comrade in surprise, the sudden movement nearly causes the bolt that pierces his head to miss, but the impact is so powerful that even the poorly aimed shot kills him instantly. A third one gets hit by a flaming ball of fire, while a single bolt misses it’s target and flies wide (11). Margaret quickly adjusts her aim and takes out the Orc that is injured by the fire with her second shot. Kala struggle a little bit to climb through the breach in the wall and falls a little bit behind.

Two of the Orcs in the north east corner are dead, one is unconscious (5) and one (10) is alarmed that something is going on.

The conscious one seems to be confused and slow to react, you all go before him in initiativ. 

Otrov:
