(Okay, it's round 2. Back to the players.)

Lan’s roar deepens into a basso rumble as bronze-bright scales race across his arms and neck; spine and sinew stretch, shoulders hunch, and in a heartbeat the dwarf collapses forward on clawed forelimbs—no longer miner’s stone but living brass. A crest of dusky plates flares as he lunges, jaws snapping with a crack of thunderous teeth, yet the swirling wraith slips aside and the bite closes on empty, freezing fog. Lantern shards now gleam between draconic fangs, and the brass dragon crouches, eyes molten with renewed fury.

Bonus: Dragon Shape (Brass)

"Take THAT!"

(OOC  reminder her AC is. 8 pts better from Shield & Mage Armor, .  I didn't see it on her sheet

Zheng points his crossbow at the creature.

True Strike Hit: 17 Damage 13 Radiant/Force

As Xi casts scorching ray at the Mistfolk, one of the blasts catches it through the side, sending wispy looking mist floating up and into the atmosphere. Zheng's crossbow bolt also pierces it's chest, and with a gurgle and a cry, it breathes deeply in, and exhales an airy blast of sleet, wind, and snow at you.

Make a Con save.

(all of us? if so:) Lan Con save: 16

(If it matters Zheng is about 40 or 50 feet away from the creature. He started in the back of the group, hit the creature first rond pushing the creature 10 feet away and moved 30 feet away from the creature round 1.)

Zheng's Con Save: 16

(can she do a bonus action this round?)

Con Save   13

Con Save   13

 (Sure, why not?)

The MIstfolk's smoky blast of fog deals 3 damage to Lan.

(Back to you I think?)

(Bonus action;)

As  she realizes that Lan has been replaced by a draconian being with the appropriate WTF expression, she realizes what happened & shrugs.

;"Lan, I'm casting a spell.  (Touches him) Now you can breathe Fire.  Go ahead & breathe on him!"

A guttural, brass-throated chuckle answers Xi’s touch. “Sure do.”
Lan rears back, chest glowing like a stoked forge, then looses a white-hot ribbon of fire that roars through the fog and sears straight at the mistfolk’s shifting core. 

Action: release Dragon's Breath for 12 at Dex DC 12 (Xi's Save DC)

Zheng points his crossbow at the creature.

True Strike Hit: 22 Damage 13 Radiant/Force

Xi casts a Bolt of Fire at 16 to hit.  It tears through the creature for 1 point  of damage

(Sigh)

With a screeching sound like metal on metal, the Mistfolk slumps onto the ground and lies still. A few moments later, it's body melts away, and large swaths of it disappear back into the fog. Nothing remains as evidence to this encounter, except your adventurers, sweaty and standing in a clearing. The pervasive cloud of fog obscures your sight of everything beyond the clearing, except for a tall run-down tower that stands in the distance.

Lan’s brass frame ripples, plates clattering as he shakes off lingering frost like a hound shedding river water. Smoke curls from his nostrils; amber eyes fix on the half-ruined tower looming through the murk.

“Best we press on while the path is clear,” he growls, voice now a furnace-rumble. “I’d thought the tower hugged the village edge, but it lies deeper than rumor claimed—no telling what else nests between here and there.” He lowers his crested head, ready to lope forward on clawed limbs, and waits just long enough for his companions to fall in beside him before padding toward the broken spire.

(His dragon form lasts an hour. @DM can you remind me when the hour is up?)

Zheng nods.

"It would be best to continue quickly so that we hopefully do not encounter more of those creatures."

Zheng will continue towards the tower.

"You know, I thought I was the only one, but how many of us have magic or draconic powers?"  asks Xi.

 (Will do)

Zheng looks at Xi for a moment.

“I am able to connect to the light of the world. To most this probably seems like magic. I don't think the Shang Dynasty would see any difference between the two.”
