(Spar: Others can also try to dig out, but it is still DC 15 Athletics check. Since you are blocking the path of the worm, attacking it is probably better than digging out the cleric.

Quillary: Hmm... I am still asking for a Giant Badger Athletics (STR) check. On a pass, 2 successes (Drusk is completely free). On a fail, 1 success (he only takes 2 damage next round).

Hildigrim: That is quite the series of die rolls. In a different campaign, I've been complaining about all the low rolls my halfling is getting. You just got two 1s in 5 rolls, and all of them were less than 10... that is quite annoying.)

Hildigrim is slipping around in the first worm's gore, so his arrow shot is not the finest. Fortunately, the sound of Volo's hooting guides him where to shoot the arrow (18 damage).

Jorin and Spar to go.

Soar barely has a chance to take in Hildigrim’s help, but she casts an appreciative look at the brave owl and whatever it’s doing. She glares at the second worm and moves her hex over to it, and then tries two more attacks. She doesn’t process the sudden badger next to her.

Attack: 23 Damage: 11 plus 6 damage from Hex
Thirsting blade Attack: 7 Damage: 14 plus 4 damage from Hex

(Same as before just with 3 less damage per hit with Hexblade’s curse defunct.)

Strength check for the Giant Badger: 8 

(Not very strong, but stronger than Quillary, so a win, I guess, and the opportunity for two successes is good!) 

(Oh that was a clever idea with the badger!)

Jorin pivots and slashes wildly at the still living worm, hoping to draw its attention away from his buried friend.

• Movement: Into Melee range of the worm
• Action: Reckless Battleaxe!
  • First Attack: 25 Damage: 11
  • Second Attack: 20 Damage: 17
• Bonus Action: Reckless Moonblade Attack: 22 Damage: 13
• +6 radiant damage to the first strike that lands

Q-Badger rips into the rubble, but she only digs aside part of the debris covering Drusk.
(She wants to be careful not to tear off anything that isn't stone.)

Jorin's 3 strikes do 50 damage.

Spar still isn't used to getting Hildigrim's advice during combat, and staying clear of Jorin's whirlwind of slicing causes her to miss the first strike. The second one does 16 damage.

YPW2 was moving towards Spar, but Jorin's reckless attack lands him right in front of the frothing creature as it was about to attack.
Bite and stinger at Jorin.

• Bite Attack: 15 Damage: 18 piercing
• Stinger Attack: 10 Damage: 8 piercing
• *If* the stinger hits, roll a DC 14 CON save. 14 poison damage for a fail, 7 for a success.
• Rage will reduce the bite and stinger damage, but not the poison.

New round...

YW2 has taken a cumulative 84 points of damage. It is still thrashing about, but you feel confident of victory after seeing how much you hurt it last round.

(I'm going to roll for Drusk digging himself out. It would be nice to get a success before combat ends. That would also free Q-Badger to do an attack.)
Drusk takes 2 damage from being buried. Needs one success vs. DC 15 to get free: 4

Everyone can beat up the juvenile delinquent purple worm.

CON Save: 25

 So that is...26 damage total

Ugh, that dice roler had a 25 there.  I'll use the game log so as not to hold things up.  Game log gave me a 20.

(Got it.
I'm still using the forum roller most of the time, but that Game Log is handy when problems pop up.)

The giant badger pauses for just a moment to lick Drusk's face with its giant, raspy tongue, before it turns and falls upon the worm with its much feared CR 1/4 multiattack, bite and claws going!

Bite Attack: 7 Damage: 4 piercing 
Claw Attack: 17 Damage: 7 slashing 

Hildigrim breathes out a sigh of relief as Drusk's head pokes up out of the rubble. Then, asking Volo for another fly-by, the halfling fires another arrow.

Attack: 12 Damage: 14

Forgot advantage: 23

Hildigrim's arrow leaves the young purple worm visibly weakened.

The giant badger gallops over.
Quillary is about to take a bite, but the slimy flesh causes her to recoil in disgust. Instead, she gives the worm a hard whack in the head with the paw.

YPW2 collapses to the ground. Combat is over.

Drusk dusts himself off. He sees that the collapse of the ceiling ended a few feet away from where he was buried.
"Missed it by that much."

Drusk suggests that he casts 2 Cure Wounds on Jorin, and that he drinks 2 of the 4 (temporary) healing potions.
That won't completely heal either of them, but it should be enough to allow the party to keep going without taking a rest.
(Is that okay, or would the party prefer something else?)

Drusk also asks Quillary to stay in Giant Badger form for slightly more time.
Just before he was buried, he noticed something sparkling on the ground near where he fell.
Maybe Quillary and the others could dig it out, while the healing is going on?

Spar collects herself and tosses a temp potion to Drusk. "I kept trying to get their attention. I'm not usually lucky. But, now we're all trapped here, unless we can find a way to double back. Shiny, you say?" she says, and helps to look around for anything interesting. She casts light on a pebble and looks around.

Investigation: 6 and 5 if helped

Q-badger nods in agreement and snuffles about until Drusk points where to dig, then digs.

Drusk casts two Cure Wounds on Jorin, which heal 20 for Jorin in total, and 6 for Drusk (life cleric).

Drusk thanks Spar for tossing the potion, and drinks two of the temporary herbal potions.
Makes a face. "Tastes like they also use this to clean the stone floors." Drusk is healed another 14 by the potions.

After Spar tossed the potion, she lost track of the spot in the rubble. She starts digging in the wrong place.
Everyone now knows what it looks like when a Giant Badger is rolling her eyes.

After Quillary, Hildigrim, and Spar are digging in the right place, you discover some sparkling items stuck in dried out worm poop.
It is many months old, enough that it can't be any of the scouts you are looking for. It might be the remains of some forgotten Zentarim patrol.

You find a mostly digested sack that covers a pile of coins: 30 platinum and 200 gold. (I'll add to party funds, unless there are other plans.)
There are several shattered bottles, but combined there is enough untainted fluid for a greater healing potion. (You just need to transfer it to a suitable container.)

(Luckily, we just emptied a few bottles!)

Drusk and Jorin finish up the healing spells a short distance from where the others are digging.
Drusk remembers that some warriors like to shatter their mugs after a celebration. He smashes one of the empty flasks on the ground.
The Giant Badger quickly gets in his face to stop him from breaking the second flask, gesturing with her eyes to the pools of healing potion that the group has found.

(Any other activities, or continue onwards?
Who is going to add the greater healing potion to their inventory?)

Quillary will stay in badger form for now. Her Survival (+8) and Perception (+8) skills are the same, except she has Advantage on smelling perception now. She will snuffle along behind or next to Jorin, as before. (Giant Badgers are just Medium sized, so she's not taking up more space than before.)

Jorin goes rummaging through his pack, looking for a skin of ale to offer Drusk in order to clear his mouth of the potion taste.  His face scrunches up as he fails to find any, however he pulls a cracked orb from the pack and holds it up, looking at it for a minute before realization dawns on him.

"Kargost", he says, and the cracked drift globes lights up and drifts off in front of him. 

(This is an accurate retelling of me scrolling through my inventory looking for a keg of ale or some other alcohol, and then finding that Jorin has a cracked driftglobe, lol.  He'll send it out about 15 ft ahead of him to provide an additional area of bright light (20 ft radius, so now he can see about 40 ft ahead of him in bright light and an additional 20 ft of dim beyond that.  In larger areas or longer tunnels, he'll move it further, about 35 ft ahead, giving him bright light out to 55 ft (15 from the sword, 40 from the full diameter of the globe) and then bring it back in as the areas tighter or they approach a blind turn.)

"Kargost", he says, and the cracked drift globes lights up and drifts off in front of him. 

("Cracked" is not just descriptive. There is a separate entry for a Cracked Driftglobe . It does not have Daylight and levitation abilities.)

(The periodic checks are Survival, not Perception, but since you are tracking where the scouting party went a few days ago... No advantage, but let's reduce the DC to 13 for Q-Badger.)

Survival check to continue following the scout trail: 26

During the next hour, Jorin continues to call out a password and toss the cracked drift globe ahead of him, scowling when it just falls to the ground.
You warn him that if he isn't careful, he might shatter the damaged globe, but he repeatedly insists that the next time the levitation will work.

Jorin tosses the globe 20 ft. ahead, and it again plummets to the ground, but this time with a "splat".
Starting from 10' ahead (midway between Jorin and the globe) and continuing for another 30', the floor and walls are excessively muddy and slick.
Rather than the grayish clay-mud that is common in these caves, this mud is brown-red.
With Jorin's blacksmith background, the mud has the color of corroded iron. Perhaps the area ahead has a lot of moisture and ferric minerals in the rocks.

Quillary as badger sniffs ahead. Perception (with Adv!): 18
