Mr. Fists, as you call out, you hear a sound coming from beyond a door that leads further west; it slams open, and you see two large... things that look like armour, but they move on their own, with no creature inhabiting them.  They seem to fix upon you. 

Everyone roll initiative please.

Initiative: 6

Mr. Fists Initiative - 14

Initiative: 14

Initiative: 18

Verdan's initiative:  10

Armour initiative:  17  4

Round One:
Nalla and Verdan
Armour 1
Sunshine
Armour 2
Mr. Fists and Telias

Nalla and Verdan are up.

(The doors between the three rooms are all now open sufficiently for anyone to pass through without a problem, even though they look shut on the map!)

Nalla will make sure that she has proper aim before she begins to move her hands slowly about, fire forming before she lets a Firebolt towards the armor.

Firebolt: Attack: 21 Damage: 1

Whoosh!  The bolt of fire blasts through the doorways and burns into the armour, causing scorch marks to appear.

Verdan attacks the same armour, Armour 1, with his shortbow:  Attack: 12 Damage: 9

But manages to shoot the floor.

Armour 1 floats menacingly towards Mr. Fists, the nearest intruder, and wielding no weapon it simply tries to slam into him:

Attack: 21 Damage: 4
Attack: 7 Damage: 4

Two really solid, powerful blows, and Mr. Fists drops to the ground, unconscious and bleeding out.

Sunshine is up.

Seeing Mr. Fists go down in just a few smacks, Sunshine keeps her distance. She moves into the doorway and fires her short bow at the first armor.

Attack: 16 Damage: 3

The arrow clangs as it hits the armour and sticks in a hole, doing a little piercing damage.

Amour 2 lumbers forward; these things are not graceful and not fast.  It moves towards Sunshine and Telias, reaching them and ready to attack next turn.

Telias is up.  Mr Fists needs to make a death saving throw, please.

Mr Fists Death Saving Throw - 8

Telias looks over to the downed monk and the staff glows a bit. "Rise." He then goes to hit the armor in front of him with his staff.

BA: Healing Word

A: Attack: 24 Damage: 5

Telias, that looks like a solid strike, but somehow a bit disappointing that the armour resisted it so much.

Healing word:  4

Mr Fists, you wake with 4 HP.  We'll disregard the saving throw; it's the start of your turn, you are prone but conscious.

Mr. Fists is up.

Mr Fists will use half of his movement to stand up. He'll attack with his short sword.

Attack: 13 Damage: 6

Mr. Fists will then use a Ki point for Patient Defense, which allows me to take the dodge action.

That's my turn.

Alas, that attack misses, as Mr. Fists is still disorientated from his neat-death experience.  But he manages to get ready to defend himself.

Round Three:
Nalla and Verdan
Armour 1
Sunshine
Armour 2
Mr. Fists and Telias

Verdan shoots at Armour 1:

Attack: 11 Damage: 9

But misses.

Nalla is up.

Nalla will gather her magic and bkast the armor that is near her kenku companion with Magic Missile.

Magic Missile: 8

Three magical globes of energy slam into the armour, but it seems undeterred.

Armour 1 attacks Mr. Fists, once again slamming with its whole body, if you could call it a body.

(With disadvantage from the Dodge action)

Attack: 7 Damage: 2
Attack: 6 Damage: 5

The agile kenku dodges easily.

Sunshine is up.

Sunshine disengages from the approaching Armor2 and slips past it into the next room. Tucking herself back into the corner, she fires another crossbow bolt at Armor1.

Attack: 24 Damage: 14

That's disengage, right?

Sunshine, your arrow penetrates the armour where the chest would be if a body occupied it, and the armour slowly crumples to the ground, unmoving. 

Armour 2 attacks Telias, as he is closest:

Attack: 15 Damage: 8
Attack: 20 Damage: 3

The clumsy movements of the armour are easy enough to avoid, and Telias does so skillfully.

Mr. Fists and Telias are up.

Mr Fists will move into the room next to the armor and attack.

Short Sword Attack: 18 Damage: 8

Bonus Unarmed Attack - Attack: 15 Damage: Unable to parse dice roll.
