Ruby seeing more Night Terrors attacking jumps into combat to assist.

Lighting bolt at 3rd level if possible I would like to line them up and hit both. 16 dex dc to save. 31 damage on no save half on a save.

Seeing the new and very creepy room in front of them, Rai's hands instinctually move to where his pouches and weapons should be stored. For a second he curses his muscle memory, as he can almost feel the familiar sensation of his well-used tools stored safely in leather pockets. The memory of them feels so real... until he looks down in surprise to find that they really are there! He allows himself a moment of pure confusion before the speaking toys snap him out of it. The sight of children, their necks articulated like a terribly constructed doll's, sends chills like lightning down his spine. "Wait..! Hold on a minute! Who are 'They!?' " The second the words come out of his mouth he knows it's to no avail, the children are gone already. He zips open a pouch, and there with his trusty alchemists tools, Iemiru is happily lounging about as if in a hammock. He only has time to give a gently warning, "Iemiru, buddy, wake up," before shoving his hand in there and pulling both his tools and the dragon out of it. He places it on his shoulder as it protests with a small mechanical trill. "It's good to be able to see you again. I promise I'll make it up to you." Tools in hand, he targets the Terror not currently being targeted by Ferro, and mutters something under his breath. His tools glow in a sickly green light, and the light launches at the Terror.

To Hit: 21
Poison Damage: 9

Without skipping a beat, he commands Iemiru to "Attack this one!" It obliges, the small barrel protruding from its mouth and shooting a beam of light at the one Rai is currently trying to hit.

To Hit (custom roll because I can't find anything for my Homunculus on my sheet): 18+7= 25
Force Damage (another custom roll): 4+4=8

(Rai's Turn:
Action: Cast Ray of Sickness at 1st level
Bonus Action: Command Homunculus Servant

Iemiru's [Homunculus Servant] Turn:
Action: Force Strike)

(ooc: In the Game Log it should show that I rolled to hit twice, but the first roll was a mis-click on Acid Arrow.)

Belko goggles at the sight of the new horrors but doesn't forget to doff his cap to the possessed toys in thanks for their concern.

He claspes Rai and Ruby by the elbow, " You've got this."

( https://www.dndbeyond.com/spells/heroism on both. +4 temp hp and Immune to Frightened )

He then turned to Ferro, " Have at them, Compadre!"

( Bardic Inspiration: 1d6 )

The lightning hits the terrors but doesn't seem to give as hard of a ZAP as you might have hoped, Ruby!

You and your pet make contact with the terrors Rai, the strange mists billowing in recoil as your strikes are true!

However, Belko was not in melee yet so no sneak bonus, but you still manage to sever one down pretty well Ferro! Unfortunately they see you and turn their attention to you, sinking their ghostly hands into your skin, hitting you for 36 (12 and 24) necrotic damage!

On the one that hit him for 24 damage Ruby uses her reaction to cast silvery barbs to make it reroll taking the lower result to hit.

Ruby seeing one if the Terrors looking hurt will cast chill touch at it 11 to hit 10 necrotic damage if it does.

Belko looked aghast and charged the thing attacking Ferro, slashing away.

" Away from my friends you threatening fart!"

Attack: 23 Damage: 4

Reaction: Cutting Words on the next attack that hits. -1

Ferro groans in pain as the claws find him and seem to burn with intense cold, causing his skin to shrivel and crack where they hit, like freeze burns. He twists and dodges best he can to avoid the worst of the attacks (uncanny dodge reaction) (damage to be calculated when silvery barbs are considered)

Then he takes courage from his new-found friends' encouragement and wields Black Widow to try to take out one of the misty monsters.

To hit 26

Damage 10 + 14 sneak attack

(They succeeded against the silvery barbs)

Ferro will take 24 total (12 and 12)

Rai looks at Belko with a confused look for a split second, but ultimately is grateful for the help. "Thanks, Belko." Feeling a little more confident than before, he raises his tools again. Wielding his glass stirring rod like a wand, a spray of sizzling acid jumps out of the tip and at the Terror that has Ferro in its grasp.

To Hit: 15+3 (+3 from Alchemical Savant)= 18
Acid Damage: 10

"Iemiru, you know what to do. Ferro, are you okay? That looked nasty!" Iemiru continues firing away at the second Terror, the same one it targeted the turn before.

To Hit: 18+7= 25
Force Damage: 4+4= 8

(Rai's Turn:
Action: Cast Acid Arrow at 2nd level
Bonus Action: Command Homunculus Servant

Iemiru's [Homunculus Servant] Turn:
Action: Force Strike)

Ruby your chill touch misses as the misty monsters slip around with ease!

Ferro your blade though manages to catch one off guard and in a devastating strike makes it evaporate back into the fog!

Belko the terror simply laughs maniacally in your face as your attacks go wide!

Rai, you and your pet both hit the remaining foggy terror, making it react with a ghostly howl! It's foggy billows having trouble coalescing now!

The remaining terror tries to lash out again at Ferro but it's shadowy fingers are too slow this time!

(next round)

Ferro will try to finish it off. Black Widow flickers quicker than the eye can track.

To hit 24

Damage 12 + 19 sneak attack

Ruby will cast chill touch again with 22 to hit and 7 necrotic damage.

Belko went for the slash again.

Attack: 8 Damage: 17

With his free hand Rai unsheathes one of his daggers, removing it from the pouch strapped to his leg. "Go back to the depths of hell where you belong!" Iemiru quickly jumps down to the ground, preparing another shot as Rai runs forward and slices through the air.

To Hit: 22
Damage: 7

"Again!" Rai shouts, and Iemiru fires at the Terror.

To Hit: 2+7= 9
Force Damage: 2+4= 6

(Rai's Turn:
Action: Attack with Dagger
Bonus Action: Command Homunculus Servant

Iemiru's [Homunculus Servant] Turn:
Action: Force Strike)

Ferro and Rai your attacks strike true once more and in one final hiss and howl the terror takes one last strike at you Ferro! (Take 5 psychic damage. That is with the -4 from Belko.) The mist driven monster then evaporates and a moment later in a nearby mirror you see the ghostly faces of the two children, smiling sadly at you. They then look off in the direction of the short hallway to the side and back at you all. "Mother was over there I think," the young boy echoes softly. "Thank you for ending the game for now," the slightly older looking girl answers after.

(combat over)

Ferro creeps towards the hall, muttering to himself about what horror awaits him next, and how he’s not at all sure that any amount of jewelry or other reward will make up for this miserable quest.

If he doesn’t see anything out of the ordinary, Ferro will proceed down that hall, keeping his eyes equally peeled for both treasure and trouble.

Belko says his goodbyes and thanks the children leaving them with an image of a juggling teddy bear  ( Minor Illusion) as he turns to follow Ferro.

" Poor tykes,", he mutters as he joins Ferro in the hall.  " We find their mother now?"
