The tiefling lowers her hand slowly. “Er, yes. Well. I’ll just help myself up then.”  She stands up and stretches the last bit of soreness out. “Well, if we are introducing ourselves my name is Lerissa, and if you don’t mind I’ll take a look at the door as well.”

Investigation: 22

"Oim Twist 'n 'es Symon."  Twist say.

"Allow me to apologize for my atrocious manners, I am Symon,"  Symon says with a slight bow. "Pleased to make you acquaintance. And who is you friend?" he adds, pointing to the half-orc.

"Out o' me way, fluff, th'res work t' bes done." Twist growls as he, too, heads to the door to check it out.

Investigation   17   Perception   25

After introductions are made Kugu, Larissa and Symon check out the door. There is no handle on this side and trying to push it open doesn't do anything. It doesn't budge. You do see that in the stone next to the door is a small hole in the wall. You'd guess it's for some kind of key but it doesn't look like any keyhole you've seen before. 

With Brocc and Symon talking about smashing the globes and traps Kugu and Larissa you do recall....

Kugu eyes the door, wanting to try her strength against it, but feels the chief of  her reminding her there is a time and place for her rage and times to try other, however less satisfying, methods.

"Larissa, you have that key we found in one of those ball thingies? That might work on it." Kugu can't hide all her disappointment out of her gruff voice.

“I certainly do. I hope it was worth digging around in all that muck.” 

She takes the key out and tries the hole to see if it fits, and if so turns it hoping she didn’t miss a trap somewhere.

"A key, you say? In them?" Brocc looks up to the Orbs with renewed interest. "Fascinating... Ah... AHahahahah... hah... I suppose then for us, the key to opening the door--" He looks back and points to Kugu and Larissa both. "Was you two! Or at the very least, we can ignore the one you open, if does not work on our lock. WHICH eliminates two for us to worry about at the very least, assuming of course *ahem* You two remembered which one it was you open."

He raises a bushy brow. "You two did remember which one you opened, yes?" He asked. Regardless of whether or not he's left with a grin from confirmation or with furrowed brows, he waits long enough to see if the key works. And if not, he walks beneath the southern most one, and winds up to throw his hammer into the middle orb furthest from the door.

(For reference, if we come to Brocc needing to break another Orb. With the ? being the new one he breaks.)

Larissa tries the key. It fits in the hole but doesn't open the door. 

Brocc - Now that you're thinking about them having broken one of the globes before you realize there's some, as was said before, 'timey wimey nonsense' going on. There should be a broken globes in here from Kugu and Larissa but there isn't. Also the shpynx said that you would always perceive yourselves as being the first to come through the mountain. So you know there's some weird time stuff going on with Kugu and Larissa being sucked into your time.

Brocc throws his hammer and breaks the indicated globe. It shatters and 2 things fall out of it.

(For this one, and if any other globes need to be broken, people can stand under the globe and try to catch anything that falls out instead of searching through the mud once it falls. It's a DC10 Acrobatics or Athletics check to catch stuff.  DC15 Investigation or Survival to find it in the mud)

Twist looks back at the others busily breaking the globes, "Oi roightly loikes smashin' thin's, needs any 'elps?"

Symon shakes his head, "You might want to make sure there is a bit of light before you break the last one, could get a bit dark in here."

Symon Twist joins the others under the globes, reaching up to shake one of the unbroken ones.

Seeing the key doesn't work, Kugu turns back towards the globes. Upon seeing Brocc break one of the globes and hearing Twist offer to help break things she rushes over to try to catch whatever came out. 

Athletics: 23

Larissa steps back and watches, staying out of the way.

7  8  9

6  5  4

3  2  1

(Slightly modified Brocc's globe layout so they are numbered.  The red ones are broken)

Kugu easily catches 2 items that fall out of globe #2. A potion and a key.

(Just to expedite things I'm going to say that Symon gives them all a shake)

They all sound the same with a rattling sound coming from all the globes except globe #6

Break them all, careful to catch whatever falls out, except for number 6, Symon Twist will wait on the one, "Bes 'r luck th'un 'ld be th loight."

"For once, twist," Symon says tartly, "you may be correct in your guessing."

Kugu hands the key to Larissa then holds up the potion, looking at it through the light before handing it down to Brocc. "You know what that does?"

Brocc stops pontificating on the pros and cons of featherfalling objects long enough to finally catch the question. "Whatwhat? Ahhh! Yes. I mean, well, not yes, as I know yet. But, I could know it innnn... ten minutes or so. A bit tapped on the reserves to manipulate the greater magics for the quick and fast identification. Once we have that door open however, I will be glad identify any and all we find. For now." He hands it back to Kugu. "Why don't you hold on to it for now, Lass."

He gives Kugu a kindly smile. "And I don't know about breaking them all, but certainly some of them, yes. Be sure to check to use the keys each time though, least one of these have a not so happy surprise. Haha! Now, Miss Kugu my dear. Ready yourself." In a swirl of mist, Brocc's warhammer reforms clean in his hand before being thrown up at another corner globe(3). 

Larissa takes a piece of string from her gear and ties it to the key already tried, and puts it in a pouch. Then she takes the new key from Kugu and inserts it into the hole and tries to turn it.

Kugu gives Brocc a strange look when he calls her lass then readies to catch whatever falls from the globe.

Athletics: 16

She also tucks the potion away with the gems she had found previously with the key she originally gave Larissa. 

The key from #2 doesn't work either. So Brocc throws the hammer at #3 while Kugu readies to catch what falls.

Several things fall out: an amulet, a beaded necklace,  and a key but Kugu barely has time to catch them a shadowed shape falls down on top of her. The shape tries to coil itself around her...

Attack: 11 Damage: 13 Necrotic damage.

If that hits your STR is reduced by 3

That brings us into initiative:

Brocc: 8

Symon: 17

Kugu: 5

Larissa: 13

Shadow: 14

(I missed advantage on Kugu initiative; so adv roll: 8

Current initiative order: Larissa, Shadow, Brocc, Kugu, Symon

(Kugu: I adjusted your sheet to reflect the temp STR loss, you'll still have to do HP though)

(Ouchies! Thanks, dmg is marked)

Without a word Larissa quickly draws her shortswords and tries to cut the thing off of Kugu, slicing with first her Shortsword, +2 then her Shortsword

Attack: 8 Damage: 1

Bonus Attack: 6 Damage: 4
