Ankita breaths a sigh of relief when the group makes the decision to turn around.  She walks in front of Melchor as they head back over the bridge.  "Yes, a rest would be a fine idea."

Dm roll: 4

Dm roll:19

You are able to have a short rest with no problems, the woman you nearly encountered not following you.

Heading south down the tunnel, you come to a wall with a dead end on the right, and more tunnel on the left. Looking left, several rough-hewn mine tunnels converge near this spot, shored up by old timbers. Patches of weird fungus or lichen cling to the walls in places. A soft breeze moans through the passageways. The corpse of the Duergar and the tentacle beast Sandre and Petra lie here.

The tunnels are just wide enough for 2 abreast. There seems nothing to do but keep exploring the tunnels. You run into several dead ends but do find 2 doors in the northern area, and a longer more promising tunnel in the south.

Dm roll:18

And one more: 1

At the spot m23 above:

A localized cave-in partially obstructs this disused mine tunnel. A heap of rubble stands six feet high and blocks a ten-foot long section of the passage, but the tunnel definitely continues past the collapsed section.

There are 3 slave workers here clearing the rubble, a dwarf and 2 humans. Guarding them with its back to you is an orc.

Shrek despises slavery.  So, without hesitation, he quietly approaches the orc guard, rushing at the final moment to surprise it with a hopefully fatal pinch-

Umber Hulk Claw Attack: 17 Damage: 12

Shrek hits it hard but the helmet seems to absorb the blow.

(I'm not going to roll initiative here. Just kill it :p)

Olaerys takes the opportunity as well with the guard’s back turn to bring his battle axe down on him.  

Battle axe :  Attack: 22 Damage: 7 

The orc is hit a blast of warm mine air as Olaerys misses wildly with his axe, nearly decapitation Shrek on the folliw through

Randall charges into the fray with a stab from his trusty spear... Attack: 17 Damage: 10

Clank. 

After imbuing her staff with shillelagh, Ankita swings the club at the orc, flanking it with another of the party as he is being surrounded...

Attack: 26 Damage: 10

Ankita clubs the thing hard and it does not like it one bit

Since melchor won't kill this, I'll get this out the way:

The orc appears stronger and more 'cognizant' than you would expect.

It responds to Ankita's savagery with its own Attack, swinging its huge axe 

Attack: 26 Damage: 16

Melchor makes a grasping motion towards the orc, bringing forth a spectral hand to grab it... 'Frigis...' he mutters at the same time

Chill Touch attack: 24 Damage: 1 necrotic damage

Ankita is hit hard by the huge axe, getting pushed back a step.  Bloodied now, she spins her staff in anger and attempts to bring it down hard on the orc.

Attack: 24 Damage: Unable to parse dice roll.

Randall does his best to help Ankita bring down the brute.  Attack: 10 Damage: 12

He will also be sure to use his reaction to Protect his nearest ally within 5' who comes under attack.

(If alright with the DM.. going to use her bonus action now)

In a blink of an eye, Ankita turns invisible.
