Dex Save- 4

Randa is Blinded, making a random Melee attack and takes 23 damage and is prone.

Morgan's wisdom saves: 1, 10, 6, 15, 14, the d8 are 2 and 3. 
Dex saving throw: 12. He is not blinded and the attack misses. 

Morgan spends his turn watching around confused. By pure chance, he doesn't look in the direction of the light and dodges the monster's bite just because he's too unstable on his feet.

 It will affect your turn most unfortunately.

 Don't forget to factor in your 8 thp.

(OOC: in the end to wich direction did my character moved?)

Brother Bombur is momentarily stunned by the virtual insanity assaulting his ears, while Frekor immediately dashes north into the wall of a building. His legs propel him onward still and he drags against the wall in his confusion, rolling against the wall until he is roughly 30ft away from the monsters.

DM: Frekor is outside the range of their brain-breaking gibbering. He can hear them still, but at this range, it sounds more like the audience of a theater or gladiator stadium and is not so confusing.

As Frekor flees in his temporary insanity, Jacaranda is driven to insanity herself and slashes out at Ylis, thinking it to be these abominations and being blinded to the point that all she can see it a snapshot of their shifting, impossible forms in his light-blasted vision.

DM: Scimitar Attack 14 targeting Ylis, Slashing Damage 7.

Randa is then pulled under the yanking and biting terrors as they smother her and begin to pull her to pieces.

Morgan, like Brother Bombur, is unable to form a coherent thought in the discordant sounds and is rendered temporarily stunned.

The only person who seems to be able to handle the noise is Ylis. Having spent her entire life with ears so large, she has developed a bit of a mental callous to the noise of the bigfolk in the cities. She is entirely unaffected and even manages to avoid the luminous loogie launched at the party.

DM: Ylis is the only one able to take an Action this turn. Make it good. 

Ylis did not fail her Dex check so can still use her reaction to cast Silvery Barbs to make C re-roll its attack on Randa. Then allow Bombur to reroll his failed WIS save.

DM: I love it. Rerolling now. That is an 18 to Attack on the new roll. 

Ylis will dance back away down the street 25 feet (left). "Suck suck suck suck so gross so gross!"

"Burn in the light!" she cries pointing at the gathering of foul creatures and unleashes the power of the Moonweaver in the pillar of blazing light!

Targeting the join between ACDC with Moonbeam lvl 3 for 14 Radiant Damage, DC 15 CON save for half.

Finally she will flick her spear with soft white glowing vines (Shillelagh). 

[well done! My new roll is a 24 for that failed Wis save. Assuming that means I get an action now?]

It does, Bombur! Fire away. 

Brother Bombur felt a need to bring the gospel of the Allhammer to these pitiful creatures, even though he knew it would have no effect. “I shall bless thee with holy fire!” He screamed as he backed away. 
[move straight west as far as I can. I believe that’s 25’ since one square is difficult terrain. Opportunity attack from E]

Lifting up his blessed weapon, he lets loose a shot on the farthest creature. 
[attacking A. Rolled an 11 total 12 damage total (counts as magical in case that matters). everything within 5 ft of the target must make a Dexterity saving throw (DC 13) or suffer 1d8 (I rolled a 3) fire damage.]

Bonus action: Bombur also summons a righteous ethereal hammer between himself and the closest creature, and the glowing weapon strikes at that creature. 
[spiritual weapon. 19 to hit. 8 radiant damage on E]
