Sigurd - Athletics (Advantage +6): 24, Investigation (+3): 10

Pushover springs into action at the slightest mention of her name and puts all her efforts into the investigation of the supports. [Investigation: 18 + 6 = 24]

[Investigation: 12 + 4 = 16]

K also pitches in by investigating the cave-in and deducing the best way to remove the debris and support the walls without the whole thing collapsing.

Sigurd remembers he has a pick & a shovel.   He takes them out of his backpack, offers the shovel to whoever wants it and starts with the pick to break up the larger pieces of rock to make it easier for them to be moved,

(It's a check for the whole group but the downside only happens if more than half the group fails. So no worries on this check.)

The passage is cleared of the debris, along with even using the debris to strengthen the walls as well. The tracks continue onward, leading to more turns and twists in the tunnels. Until you are stopped once more, by a tunnel teeming with vines coming from the walls, ceiling and floor of the tunnel. While not seeming dangerous, the tracks say otherwise as they display careful movement through the greenery.

Ja'Dul holds his torch close to the plants to see if he can burn them.

[If I want to check if there's something suspicious about the vines and this particular tunnel, what should I roll?]

OOC: Probably Nature for the vines.  Probably Perception for the Tunnel.    I usually use Perception to let the players know that there is most likely secret door or something unusual nearby and investigation to actually find it.  Perception is also to notice hidden traps while just walking nearby, etc.  This is just me because I play D&D online which is 3.5 rules where is "spot" (Perception) lets you know something is nearby (and how far you notice things at a distance) and "search" (Investigation) to actually find the door/hidden object.

Ja'Dul holds his torch close to the plants to see if he can burn them.

As Ja’Dul goes to test the vines, Pushover meekly adds ‘Umm, I don't know if you want some help, but if you want to save time, I’m more than proficient at fire magic. If these vines can be burnt, and are safe to, since I’ve seen more than enough animated plants attack after nearly being turned into kindling, I can clear an easy path through them by creating bonfires to burn away 5 foot squares of the vines per casting pretty quickly.’ 

Grigs grimaces as Ja’Dul approaches with a torch as well, but says nothing and instead readies himself to pull the bug-man free if those suspicious looking vines react poorly to having fire waved at them.

((the skill breakdown is here if that helps.  https://www.dndbeyond.com/sources/dnd/free-rules/playing-the-game#Skills  They tweaked the wording for 2024 a teeny bit but it's more or less the same as 2014. Sometimes a gm will let you be creative with how you use your skills, others like to stick to the rules as written descriptions.))

 [I took your advice and rolled for Nature and Perception. I don't think I got any useful rolls, tho 😅] [Nature: 6 + 2 = 8] [Perception: 6 + 3 = 9]

K watches apprehensively as Ja'Dul goes to test the vines with his torch, but since she has no reasonable explanation to back up her apprehension, she does not stop him. She tries to peer down the tunnel to see if she can spot something more suspicious or sinister, but cannot discern anything there either. 

Ja'Dul nods at Pushover, *Agreed, please see if you can burn away the vines,* he makes a welcoming gesture with his false hands, then stands aside to watch the show.

(Nature and survival would be the one for this. A natural hazard so it can be known through either skill.)

K is not familiar with this kind of plant. It's especially odd to see it down here below a city. Nor does she see any obvious trap or anything wrong with the tunnel.

The vine catches fire easily and it travels along its vine, burning it away until it reaches the tunnel walls. The fire smothers out as the dirt falls upon it.

After the plants are gone, Ja'Dul will continue following the track path.

*I don't trust anything in here...except you. You I have to trust* You hear clicking sounds which you come to understand as laughter. 

Seeing as the vines didn't react weirdly to being burned, K gives Grigor - who she saw was also worried about the consequences of setting fire to the unfamiliar plant - a shrug, before following Ja'Dul down the tunnel.

Grigs returns the shrug and follows the others, continuing to focus on any threats approaching from behind.

Sigurd takes the lead after the vines have been taken care of.

(Will need a Acrobatics, Athletics, or Survival check, at advantage with Pushover clearing the bigger of the vines.)

(Cannot burn the whole greenery away due to it would be leaving you all in a tunnel filled with smoke and fire.)
