Illezenya attempts to paint the creature purple (DC15 - Dex = 4) and does so successfully which means that the party can now see the creature as it closes on Illezenya. Before it gets there Devin and Ebonitus can act.

Initiative: Ilezenya, Devin, Ebonitus, Creature, Mullo, D.O.R.K.

After taking their rest, Devin ensures that the light spell on his shield is renewed so that he can see inside the temple.  "I agree D, the other doors need to be explored." 

As they move inside and begin to explore in pairs he nods his agreement to D to stay somewhat close in order to aid each other as needed.

As the creature moves suddenly towards them and into view Devin lobs a bolt of fire at it.

Fire bolt Attack: 15 Damage: 9

((I don't see a map in discord either))

Somebody pls tell me if they can see the map. I just uploaded it again into the SKT general channel. 

Devin flings a small ball of fire at the creature but at the last minute the creature moves in a sudden spurt towards Illezenya and the ball of flame misses.

Ebonitus - what are you doing?

(OOC: last map entered on that channel ahs a 2019 date.)

Ebonitus will fire a guiding bolt at it: Attack: 26 Damage: 18 radiant damage, on a hit the next attack on it will have advantage.

Ebonitus bolt flies true and hits the creature but it does not distract from its prey - Illezenya who looks up as the creatures maw opens - Attack: 16 Damage: 49 and bites down on the half Drow.  Fortunately for Illezenya he just manages to dodge the creatures bite.

Mullo and D.O.R.K. you're up next and then back to top of the round which is Illezenya, Devin and Ebonitus in that order.

Mullo focuses on the creature attacking Illenzenya. She throws out her arm, and a huge crash of thunder occurs right behind it.

Shatter - DC 15 CON save or take 24 thunder damage (full damage because of Channel Divinity: Destructive Wrath) - half on save

She then bares her teeth, yells a battle cry (rage), and runs forward to get as close to it as possible.

A huge peal of thunder rings out (DC 15 [Con] = 19) but while it partially deafens the party and reverberates throughout the chamber the creature simply shakes its head and focuses on trying to bite either Illezenya or Mullo

(OOC: That's uh... that's alot of bitey bite!)

D.O.R.K is sluggish to respond as she struggled to try and make sense of the thing. Shocked into action by Mullo's battle cry, the construct discarded her torch, raised a hand high, and intoned a verse glorifying the first moment the Lady of Battle delivered a celestial armament to a fledgling faithful in his time of need. And this time she would not have any expectations of its form or try to mold it. She would not even look up at it as it appeared overhead, radiating her in a faint red light.

"And so Mehmendos struck not with rage at an enemy or with regret still in his heart, but with an undiluted faith in his course finally being laid bare." She drops the hand; and with that motion, so too would the celestial weapon be brought down on the glowing creature's form. Then in continuing the story, a final snap of metallic fingers signaled a rain of divinely imbued artillery to rain down from out of the darkness above.

Bonus Action: Cast at (4th level)Celestial Armament and strike the creature.
Attack: 22 Damage: 13 force damage.

Action: Cast Holy Artillery, inflicting 13 Radiant Damage. Dex Save(DC 14) for no damage.

D.O.R.K. calls in a firestrike on the creature (DC 14 [Dex] = 20) but gets the grid references back to front because it lands nowhere near where the creature is!

"I call down the stars of night to defend me!" Ilezenya calls out, and a swirling sphere of light motes erupts around the Dusk Warden. These motes converge on the monster, attacking it. (Casting Spirit Guardians. DC15 Wis save or take 12 radiant damage at the start of the creature's turn.)

Devin throws another Fire Bolt 

Attack: 25 Damage: 14 fire damage

as he calls on a [Tooltip Not Found] to attack the creature.  A blue star appears near the thing and slams into it.

Attack: 19 Damage: 11 force damage.

Ebonitus will fire a guiding bolt at it: Attack: 12 Damage: 14 radiant damage, on a hit the next attack on it will have advantage.

While Devin's firebolt goes wide he is more successful with the blue star he has summoned which hits the creature pushing back a bit from Mullo and Illezenya. Ebonitus is equally successful with his guiding bolt. The creature moves forward and attempts to bite (1-2 = Illezenya or 3-4 = Mullo) {3} Mullo (Attack: 23 Damage: 54) who in addition to the bite damage takes a further 6 of heat damage as not only are the creature's teeth sharp they're also burning hot - the shaman now lies struggles limply in the creature's jaws.

IMPORTANT EDIT

MY BAD I forgot about Mullo's rage which reduced the total damage to 33 hp. She is now grappled (DC 17 to escape) 

Mullo you get to act before D.O.R.K. 

(OOC: since Illezenya did not designate anybody as being immune from his celestial spirits i assumed you stayed out of the radius (15') of them and what happened was the  creature spun around and bit you. If the creature had targeted Illezenya then it would have needed to make the Wis roll)

D.O.R.K. - you're up and then back to top of the order.

(@Grant: Not sure if it matters or not, but safe to assume her rage (noted here) ended early because shatter is technically not an attack? Or would it have still been allowed but was overlooked?)

Knowing full well the folly of attempting to climb the creature, let alone wrestle Mullo from its grasp, D.O.R.K once more sends her celestial arm crashing into whatever weak point Ebonitus exposed in his bolt, before beginning the next verse. Again, she would leave it to the goddess to shape the guardians called into being by her prayer, acting as only the conduit for the miracle as she marched forth intending to at least somewhat interposing herself between it and Ebonitus and Devin in her advance.

Bonus Action: Attack with (4th level)Celestial Armament.
Attack: 23 Damage: 15 force damage.
(Adv. from the Guiding Bolt, if applicable)

Movement: To get within 15ft of the creature.

Action: Cast (3rd level), inflicting 15 Radiant Damage. Wis Save(DC 14) for half damage at the start of the creatures turn.

(OOC: After the below convo about the guardians, I'll make clear as well that all allies in sight at least are exempt their effect.)

I cast shatter and then went into a rage. 54 / 2 = 27 + 6 = 33. I've still got 20 hp.

(Sorry - thought it was assumed that Ilezenya would designate all of his companions as safe from the Spirit Guardians...)

(Sorry - thought it was assumed that Ilezenya would designate all of his companions as safe from the Spirit Guardians...)

A not unreasonable assumption so lets assume that you did do that

Mullo ignores the pain of being trapped within the creature's toothy maw and swings her warpick at the creature's head, trying to bludgeon it to death. At the same time, the electricity gathering around her coalesces, shocking the creature as well.

Attack: 15 Damage: 10

Storm Aura: The creature takes 2 lightning damage (DEX DC 13, half damage on success)

Ilezenya ensures the creature remains in his circle of attacking starlight, while moving to touch Mullo's legs and flowing healing energy into her. (Cure Wounds at 2nd level - 14 for Mullo. Creature takes 14 radiant damage or half on a DC15 Wis save. All attacks against it are with advantage due to the Faerie Fire!)

The creature is both active and huge. As Mullo is restrained in its mouth you will Ned to make a to hit roll to touch her
