Derrikoth does his best to pretend that he's not helping because he's too good for it, rather than because he's embarrassed at his earlier performance with the ram.

Lydia pulls out her hammer and starts smashing along with Harshnag.

Ah'brasar joins in at Nirzeg's request, sending magical flames streaming into the thick ice. With the three of you working alongside Harshnag, the ice is chipped and melted away from the granite doors in a matter of minutes. Once they are clear, Harshnag pulls them open. 

Warm, dry air wafts out of the brightly lit room. Past the doors, the vaulted ceiling soars on 60-foot pillars, which surround a room heated by a roaring fire. The fire emanates from a bowl-shaped basin in the center of the chamber.

Arranged about the fire pit are six tables carved out of granite, with matching benches, and two 9-foot-tall stone slabs stained with blood and grease. Atop the southernmost slab are neat stacks of plates and goblets made of beaten copper, all green and black with age. However, the plates and goblets on the northernmost slab are haphazardly scattered and unwashed.

Leaning against the southern slab, around 100 yards from the entrance, is a gigantic steel battleaxe. 

Nirzeg at least step in the room, if only for a better visual. "Hard to see, but it looks like we found not just a dining hall, but our prize!" The Githyanki rubbed his hands exicitedly, and just about takes another step forward, before pause as if expecting some cavaet to reveal itself. At a casual gesture forward a grudging Zeek went flying as close to the cieling as possible, and then onwards over to the nearest table to check things out behind first pillars for any signs of occupants.

Perception: 12. (Zeek can also detect invisibility and poison in the area, if either are present)

"Do tell me, Biggest Blue. Do you or your kin have a habit of keeping such fires going even when none are present, or might the flames be some magic of giants as a whole? One designed to burn forever, to be more exacting."

“I heard of the lasting flame that was in the temple’s feast hall. I didn’t realize it was literal,” says Harshnag as he looks around the room. “If you’re inclined, I suppose you could study it.” 

But there is movement from one side of the room. A hiss and a clattering if refuse, and a huge creature comes screaming towards Harshnag! It looks like a gigantic cross between a serpent and a centipede, with rows of glowing spines on its back. Its multifaceted eyes are situated above a gaping mouth full of glistening fangs. 

// Initiative please! If you roll higher than 16 you can take your turn immediately. //

// Harshnag initiative: 11

// Rasa Initiative: 23

Nirzeg had started to open his mouth for another question, only to swallow the words in a sharp gasp!

Nirzeg Initiative: 16.

Swiper squawks in surprise and scrambled to get his crossbow out!

Scaredy-bird: 6

With his lightning fast reflexes, he successfully gets out his crossbow and shoots at the creature! 

Attack: 25 Damage: 6

Sneaks (if applicable): 9

Then promptly hides somewhere because **** that noise!

Bonus action hide: 12

Derrikoth lets out a loud curse in Draconic as he draws his sword.

Init: 9

Swiper finds ample places for hiding and taking cover among the giant-sized tables and benches, but the same features afford a rather poor target, and he misses his shot.

Having neither the desire or the ego to rush the thing for some piddly efforts at a spell, Nirzeg chooses the wise course of action; patience. To that end, he spares only a few moments to try and analyze the new threat and maybe call out a warning. Immediately after however, the githyanki is on the move, wanting to avoid being caught in the cluster **** that may become of those too close together in the next few seconds.  But seeing Zeek faffing about in the air, he has an idea, and pulls out and starts chewing on a chilli pepper.

"Gah, I hate this spell sometimes." He says, lightly crying and yet focused enough to endure the spiceness for a few short words. Zeek's eyes turn an ominous green as he awaited from 60ft high with baited breathe.

Bonus Action: Cast (3rd level)Draco's Breathe(Acid) on Zeek thru Zeek.

Action: Take Analyze Enemy: 13.

Movement: Full 30ft off to the west.

(Lydia's initiative: 14, rolled in Discord)

The creature crawls forward on all its legs, and its blue serpentine body undulates in an unsettling way. It begins to crawl over the table where Swiper is hiding, mouth agape and antennae twitching. 

Harshnag moves to intercept the larger creature, trying to predict which way it will go. "AHAHA! Now this is a challenge worthy of my time!" he shouts, brandishing his axe eagerly.

Nirzeg's observations: 

 // Players up! Map is updated. //

Derrikoth rides forward, producing a Shadow Blade from his ring, which he promptly tosses at the creature.

Attack: 21 Damage: 9

Disadvantage Roll if I can't get within 20 ft: 18

"****ers a ******* walking fryer! Keep your distance, and watch out for those spines!" Nirzeg called out as much in warning to the others while tugging at the weave. Darts of raw magic manifest between his fingers, and then are flung like throwing, homing daggers at the creature's eyes in hopes of coming close to blinding it. Meanwhile, Zeek continued to practically hug the cieling, but would reposition himself for the following turns assault upon the creature.

Action: Cast (2nd level)Astral Darts, inflicting 4 times 4 for 16 points of force damage to the creature.

Swiper hears the creature crawling onto the table from where he's hiding, the kenku trying his best to not shit himself in this situation. Once hearing Nirzeg's words, he tries to very quietly skitter under the table he's under, just to get a good distance away from the creature before poking his head out to shoot it, then hides once more!

Attack: 26 Damage: 8
Snonks (if applicable): 15

Bonus action hide: 18

Movement: On Roll20 (but I'm unsure of exactly how far I could run since I'm so tiny XD)

Lydia casts Call Lightning at 4th level on the Remorhaz. 

DC15 Dex Save for half damage. 

Lydia causes a stormcloud to appear, obscuring the vaulted ceiling. Lightning lashes out at the monster... 6 and zaps it, together with a strike from Derrikoth's thrown shadow blade and Nirzeg's inerrant astral darts. Swiper's crossbow bolt once again misses its mark. 

Rasa throws a bolt of fire at it, Attack: 18 Damage: 15, which hits but seems to have zero effect on the monster.

The creature quickly closes the distance between itself, Derrikoth, and Harshnag. Harshnag and the creature grapple with each other, and Harshnag lets out a pained cry. He takes an awkward swing with his axe, and grunts again in pain. "Forgot how hot these things were!" He says, and curses in giantish. 

The monster chitters and shrieks before releasing Harshnag. Blue giant blood drips for a second from its mandibles, but quickly sears and smokes like it's getting cooked. 

// Players up! //

Lydia will Channel Divinity to make the first bolt deal a full 40 points of damage.

Then she'll toss out another bolt.

26

"Well, so much for -that- warning." Nirzeg muttered derisively under-breathe. Otherwise unswayed by the issue at hand, Nirzeg pantomimed yanking at his chest, making visible in the motion a green and golden mass of warbling energy. "Fly true." The Githyanki utters shakely. And yet, in taking one last deep breathe, he flings the mass at the worm-like entity, transforming it with but a thought into an arrow mid-flight.

Whether it pierces its side or misses by miles, Nirzeg makes a motion with a still outstretched hand, prompting it to turn about and pass right through the creature as a wailing mass.

In the wake of such an attack, Zeek flies in just barely close enough to unlease a gout of acid upon the creature, before then taking back flight for the room once more.

Action(Nirzeg): Cast (2nd level)Soul Arrow - Attack: 27 Damage: 5 of Necrotic . Hit or Miss, expending 2 hit dice to inflicting 12 Psychic damage to creature.

Movement(Zeek): within 15ft of Monster.

Action(Zeek): Unleash Draco Breath, inflicting 13 acid damage. Dex Save(15) for half damage.

Movement(Zeek-remaining): To Gtfo back to the cieling.

Dex Save (vs Lydia) 8

Dex Save (vs Nirzeg) 2

Rasa takes to the air, making sure to steer clear of the armored monster. Seeing as his fire magic has no effect on the creature, he conjures Sparky and has him hover near Derrikoth. Rasa flaps over to Swiper and grants him the power of Longstrider, increasing Swiper's speed by 10 feet.
