Boo does a quick face-palm as she becomes aware of Majin starting to ascend the crates not daring to make noise... trusting that the Gnome knows what he is doing and leaves him to it, turning to see Carrick in the dark moving about the waifish Boo moves straight towards the human-fighter to helps to steer him in the direction towards wherever it is he is wanting to go (--but doesn't go with him--) hoping that he will not feel the need to reveal the light just yet until they see what happens or doesn't happen.

Feeling a knot forming deep in her tummy Boo has a sinking feeling this might not go well... making herself ready to react automatically at the first loud noise, crash, bam, boom, cry, curse, scream... i.e. whatever along those lines to tip Boo that the jig is up. 

Reaction: If the noise things, etc. happen, then Boo's response in the condition being met will be to fly straight up to the ceiling of the carriage (--see spoiler for her position--) to any open gaps between the tip-top of the crates and the ceiling. Perception 24 to find a possible spot to duck between and above the crates and ceiling.

Eldin, who has successfully made his way to the top of the crates and has managed to not make any noise, signals to the others. "Guys, try to make your way to the other side of the carriage. Not through the carriage of course, through the door at the other side."

Now in prone position, Eldin will sneak over to the crates where the warforged are, inspecting them as they go. Perception: 10
Do any of the crates seem out of place?

 The group enters the dark train carriage. Eldin surveys the remainder of the room, looking for things that are seemingly out of place. At first, there doesn't appear to be anything of the sort, as he hears a *THUD* noise. Majin, who attempted to follow him up the crates, slips and falls, making a clatter noise behind him. Eldin hears the whirring of the warforged activating themselves as they begin to awaken from their powered down state.

INITIATIVE: ROUND 1

Edrick
Ith
Carrick

Warforged

Eldin
Majin
Boo

END OF ROUND

Scenario: The warforged has just activated in the darkness. Eldin and Carrick are the only ones who have seen them move (those with Passive Perception 12 or higher can also hear them activating). The group is all hidden from tham at this point as they have not been able to see anyone as of yet.

Since Eldin rolled like a 20 or something and is lying prone on top of the crates, the Warforged still doesn't know he's here right? Does he get a surprise round?

The warforged are "alert" due to the crashing noise of Majin on the other side of the box, but are unaware of the presence of anyone at this point in time. There is no surprise round, but as mentioned, the group is hidden.

As for Boo, I'll keep that in mind, assuming that the scenario doesn't drastically change in between initiative turns before her turn.

@pokepaladdy

Am I knocked prone?

Nah, you're standing.

Edrick, Ith, and Carrick, it is your turns!

Carrick is going to play it safe right now and cast Blade Ward on himself. 

Guido attempts to check in with Boo telepathically but the Halfing stops him short... mentally swatting him away, 'not now Guido!'

(Since we've not heard anything from Edrick or Ith, I'm just going to hold their turns since nothing has happened to call them to action yet.)

Carrick carefully incants a Blade Ward upon himself, protecting him from physical blows for the meantime. The quiet casting seems to pick up the attention of the warforged, as there are heavy footfalls headed into his general direction.

(Sorry in advance, it might hurt a little...)

The first Warforged begin to leave their stations, headed around the corner. The first one spots Carrick; for a brief second it seems to be analysing him, as is attempting to determine whether he is friend or foe. Its decision is quickly answered as it raises its fist and attempts to smack its fists straight into he human, unaware that his spell is protecting him from the blows somewhat.
Unarmed Strike vs. Carrick: 7 vs. AC. Hit: 5 bludgeoning damage.
Unarmed Strike vs. Carrick: 15 vs. AC. Hit: 6 bludgeoning damage.
Unarmed Strike vs. Carrick: 22 vs. AC. Hit: 6 bludgeoning damage.

The second Warforged follows the first, showing that neither is apparently aware of Eldin's current location. It notes where its companion has located a hostile, as it raises its hands. Unlike the first warforged, it cannot reach to punch, but a vent appears to be inbuilt into this warforged, as blasts of energy go flying out towards Carrick!
Freakin' Lazer Beams vs. Carrick: 18 vs. AC. Hit: 4 radiant damage.
Freakin' Lazer Beams vs. Carrick: 15 vs. AC. Hit: 8 radiant damage.
Freakin' Lazer Beams vs. Carrick: 12 vs. AC. Hit: 9 radiant damage.

Carrick manages to nimbly avoid the first couple of blows from the large living construct in front of him, but takes a gut punch, as two of the blasts slam into him, his Blade Ward not helping him with them... (Carrick: 30/54 HP)

Also, Carrick please make a DC 13 Constitution Saving Throw as you are struck by the first warforged, its blow is so hard it makes you nearly buckle over. On a failure, you are stunned until the end of the warforged's next turn.

 INITIATIVE TRACKER:

How heavy are the crates? Can Eldin secretly cut the rope holding them in place and have an avalanche of steel boxes hit the two warforged?

The crates are sturdy wooden ones, but it could theoretically be turned into a capalanche if you cut the ropes and apply some force to the top of the crates. The rope is fairly thick, but with a decent cutting weapon (read:slashing) you could sever the ties and then knock the boxes, the occasional jolts of the lightning rail moving along the turns will also help alongside knocking the crates.

(OOC: Make an attack vs. the rope. It has set AC and HP to break. Once it's broken, I'd say it'd be a bonus action to topple the pile so long as you are next to it. You don't have disadvantage to attack if you are prone, the rope isn't really attempting to dodge. Either that or try and burst the rope with a Strength check.)

Con Save: 25

Majin moves so he can see the Warforged, then he take two shots one for each. he is going to use a deadeye shot on the one with lasers.

Deadeye shot: Attack: 19 Damage: 14

regular: Attack: 12 Damage: 13

OOC: Boo will keep to her original idea of how she will react if that is alright.

Boo may use her reaction as mentioned above to slip into the gap between the crates and the ceiling. She still has her turn.

Majin steps to the corner and spots the two warforged. With a quick-draw and firing, the bullets fly at the warforged. The front one takes it on its composite plating, the bullet failing to pierce it, but the trick shot manages to perfectly aim and strike the warforged at the back in the left arm. (Warforged 2: 11 damage.)

 INITIATIVE TRACKER:

All my weapons are piercing but logically speaking, can cut the rope with my dagger? I should be able to right?

Hit: 19 Dmg: 8
