Initiative order:
Dhara
Jaylen
Halhace
Kamos
Armour

Meep observes the human for a bit from a safe distance, still hiding in the tunnel. You see the human continually swinging his sword at the empty air as if he was unable to see despite the light coming off of the torch he is griping with his other hand.
For a moment you think the light is playing tricks on your eyes, as a fluid form closes in on the human. The fluid formed creature seems to be transparent with many things stuck in it. From your distance you can make out bones, even some belonging to the kruthiks.
“Stay away! Stay away from me!” the human shouts, his voice shaking. As his pursuer reaches him, the human drops his torch and swings his sword at the thing with both hands. The sword cuts through the creature’s fluid form but it causes the human to lose balance and fall. At that moment, the creature envelops him completely.

(I think what I posted would already be for the first round.  Hope everything's alright!)

(yeah I just need Kamos and Halhace to post)

(How far away was the human/ invisible assailant? )

(35ft)

Kamos is going to try to run up and punch the suit of armor.

Movement: Kamos is going to try to run up to the suit of armor (use full movement or whatever i need to, to get in melee range)

Action: Attack: (if in melee range) 17 (unarmed strike/bludgeoning)

Damage: (if it hits) 5 (bludgeoning damage)

Bonus Action: Unarmed Strike: Attack: (if in melee range) 18 (unarmed strike/bludgeoning)

Damage: (if it hits) 5 (bludgeoning damage)

Meep would watch the human curiously, remaining in the tunnel unmoving and silent. Upon seeing the human fall and brief glimpses of unexplainable floating bones. The kobold would question what it was he was seeing. Or actually not seeing. Mumbling to himself. 

faerie fire, violet on point where human was. 

 Halahace will mutter quickly as he moves his hands to cast Magic Missile on the animated suit of armor, three bolts of energy flying from his hands.

Magic Missile: 11

Dhara runs past everyone and is now 20ft away from the suit of armour. She aims and fires an arrow, hitting the armour. It seems to have damaged it somewhat, but bounces off to the floor.

Jaylen follows Dhara in putting distance between themselves and the armour.
Armour WIS save:9

Halhace casts three magic missiles at the suit. The bolts of energy hit the armour and visually damage it.

Kamos quickly moves to the suit and rapidly strikes it, missing both times.

The suit strikes at Kamos,
Attack: 17 Damage: 8

(Eremis, The thing is not invisible, per say. It’s like a puddle of water with an area touching the floor and the rest of it fluidly moving above ground. Meep can somewhat see the form as it might sometimes glisten in the light.
Not sure if you still want to use Faerie Fire?)

With the suits punch, Kamos falls to the floor motionless. The suit then turns its attention to Jaylen and Dhara and moves to stand next to them.

Halhace will move further away from the armor once he sees Kamos fall to the floor, cursing in orcish as he readies himself to cast once more. He attemtos to blast it with a Firebolt.

Firebolt: Attack: 5 Damage: 8

(If I can see it, I won't cast faerie fire. )

Meep looks back down the tunnel where he had came from then toward the puddle, "Follow Meep, sewer water. Meep show you food." The kobold would turn and make his way back through the tunnel, careful to avoid the foot traps this time. He doesn't check to see if the water puddle was following or not. 

vicious mockery @ Water Wis13 save or take 4 psychic

(do i roll a death save on my turn?)

(only if no one heals you)

Meep, as you leave, the fluid form is still wrapped around the human and does not seem to be paying attention to you yet.

Fluid form WIS save: 14

Meep would continue down the tunnel, expecting the water to have followed 

I'll run back towards Kamos, risking the attack of opportunity.  When I get there I'll fire another arrow:

Attack: 22 Damage: 11 Hunter's Mark: 5
