Phandelver and Below: The Shattered Obelisk

Quinn flies in from the rear, strikes the dead creature twice, and is gone before anyone can react. Quinn strikes hard, but this thing is tough as shoe leather.

Bryony flies in behind him, nearly as fast, and while she fumbles her first swing, she sinks a blade deep into its back. It is badly damaged.

Jurgen comes in on Bryony's heels, and finds a vantage point near her (between Jorzu and Bryony, behind the creature) before unleashing a sheet of flames that catches both the dead thing and one of the floating dust creatures behind it. (DC16 Dex Saves: 11, 13)

Jorzu does his taunting dance with the dead creature and three of the dust things before unleashing two beams of crackling energy, vanishing, and reappearing back by the doorway.
DC15 WIS Saves: Dead thing: 9, Dust thing #2: 19, Dust thing #3: 10, Dust thing #4: 16 

Hero enters the fray as well, swinging and hitting the dead creature with its metal fist.

The dead creature is barely standing. One of the dust things (#2), caught in Jurgen's flames, explodes like a dry firecracker, spraying dust in all directions. (Its nearby comrade - #1 - tries to duck. DC10 Dex Save or take 6 Bludgeoning damage from the death spray: 16 Success: Half damage.)

Boona may act next!

Confused and hallucinating, the first dust creature exhales a spray of dust at the creature (5) closest it. (DC10 Dex Save vs. Blindness: 11 ) 

Dust creature #6, behind it, is also caught in the blinding breath. (DC10 Dex Save vs. Blindness: 19 )

The third dust creature sets its eyes on Bryony and Jurgen. (Bryony and Jurgen: make a DC10 WIS Save, or crumple to the ground, fast asleep.)

The fourth dust creature turns and crashes into the dust creature behind it (6).

The fifth dust creature flies north, and focuses blindly on where it remembered seeing Boona and Hero. (Boona: make a DC10 WIS Save, or crumple to the ground, fast asleep. Hero is immune.)

The sixth dust creature does nothing but shriek wordlessly, levitating in a swirling cloud of sand.

(They each try to shake off the confusion: DC15 WIS Saves: 1: 5; 4: 17; 6: 10; Dead thing: 10)

Boona and Fergus may act next.

Fergus:

Staying well back from the dusty melee, Fergus decides sending some radiant energy the main dead dude's way would be a prudent move.  He shifts north slightly to get a better angle and sends Radiant Notes at it!  Maintaining concentration to hopefully sow more Confusion in the enemy, he stays at the back of the fracas!

Radiant Notes (Starry Wisp): Attack: 12 Damage: 5

(Edited to try and force through the rolls)

Boona marched down the wall on her right halting just beyond the nearest dust-thing and up against the farthest.

She struck out hard with her maul then turned and hit the one to her left flank.

Attack: 26 Damage: 14 + Smite 9 Radiant

Attack: 22 Damage: 15 + Smite 4 Radiant

Karst moving beside her on her left to distract both.

Bryony WIS Save - 10

An overwhelming feeling of sleepiness almost overtakes the halfling, but she manages to remain standing, although yawning and rubbing at her eyes with the back of her hand. 

( Oops...Wis Save- 10 )

( Feck)

Jurgen (rolling for poo) falls to ground asleep.

Boona pushes south past Hero, Karst behind her. The dead thing takes a wild, if distracted, swing at Boona as she moves away:
Necrotic Sword Opportunity Attack Roll vs. Boona: 6. Hit: 10 Slashing damage plus 4 Necrotic damage.

Then Boona makes a pair of mighty swings at two of the floating dust things. She obliterates both of them, and both explode in a spray of blinding dust:
Hero, Bryony, Karst: Make a DC 10 Constitution saving throw or be blinded for 1 minute. Boona: Make the same save at Disadvantage. (Dust Mephit #3 DC10 CON Save: 9 )
Then Boona collapses, dead asleep. So does Jurgen. Bryony barely manages to stay awake.

The wight, barely standing, pulls out its bow and takes two shots at Jorzu in the distance, who had taunted it:
Necrotic Bow Attack #1 vs. Jorzu: 20. Hit: 3 Piercing damage plus 8 Necrotic damage.
Necrotic Bow Attack #2 vs. Jorzu: 24. Hit: 5 Piercing damage plus 7 Necrotic damage.

Jorzu, Bryony, Quinn, Jurgen, and Boona may act next!  (Jurgen and Boona may only make a DC10 WIS Save to try to shake off the sleep.)

One of the wight's arrows scores a direct hit on Jorzu's chest. Crit damage: 3 Piercing damage plus 3 Necrotic damage.

Jorzu, Bryony, Quinn, Jurgen, and Boona may act next!  (Jurgen and Boona may only make a DC10 WIS Save to try to shake off the sleep.)

(Fergus uses his reaction to cast Silvery Barbs on that critical hit and give Boona advantage—perhaps to make that save against sleeping)

Quinn jumps back into the fray and pounces on the undead thing. Lightbringer shines a blinding radiant light as he strikes down on his target. 

Attack 1: 24 to hit for 22 total damage (8 + 8 colossus slayer + 6 radiant damage from Lightbringer bonus. 

Quinn then attacks the nearest dust thing.

Attack 2: 13 to hit for 12 damage

Boona Wis Save-  9

Advantage from Silvery Barbs- 6

B

Oona shook her head as she awoke and clambered to her feet, charging forward at the dust things with Karst at her side.

Attack: 22 Damage: Unable to parse dice roll. 

Attack: 26 Damage: 15 

(Boona's save comes too late for her to act this turn - she only awakens.)

(Meanwhile, I screwed up on the dust... Hero, Bryony, Karst: Make a DC10 DEX saving throw or take 4 Bludgeoning damage, half damage on a success. Boona: Make the same save at Disadvantage, from getting it from two sources just prior to falling asleep briefly.)

Jorzu, Bryony, Quinn, and Jurgen may act next!  (Jurgen may only make a DC10 WIS Save to try to shake off the sleep; Boona and Bryony should also save vs. dust effects.)

Quinn obliterates the undead wight with his radiant mace. Stepping over it, he swings it again at one of the levitating dust mephits (#3), badly injuring it.
