(@Orileo, don't worry, I've still got some tricks up my glamerweave sleeve.)

(OMG whose turn is it) 

(I'm waiting on Denka to tell me which way she went, but it's been a while so I'll decide for her. 1 for bad times, 2 for good times 2)

Mansion Round 3:

As Denka moves to give Scarab a shock, she feels a sudden breeze as Silvian appears at F4, swinging a morningstar at her. Attack: 18 Damage: 8

(Roll for mirror image: 5)

After Scarab dodges Denka's electric hands, an orc walks in at A2 and charges Silvian, swinging down with its greataxe. Attack: 9 Damage: 10

(Since Silvian blocks the door, Denka may make new attacks at him instead of at Scarab. The orc will also attack 1 for Denka 2 for Silvian 1)

Silvian then raises a clenched fist and casts hold person on Denka (DC 14 Wis save or be paralyzed) and then calls out to Scarab, "Hey, it'd be really cool if you could stab Swigg!" giving him another combat inspiration.

(Scarab is up)

Key: '=' Wall (15 ft), '.' Marble floor, '+' Statue (10 ft), '%' Door, '&', Tree (15 ft, provides half cover)

Denka's wisdom save. 17

Also do i get an AoO when Scarab moves out of my melee range ?

(Because Silvian is standing in that doorway, you cannot move past him)

(To summarize (if I understand correctly), Denka was intercepted by Silvian who is now blocking the door so that Denka cannot move past. Thus Denka never reached Scarab, but can choose to direct the shocking grasps (new rolls) at Silvian instead (who is in metal armour).)

(Also, can Scarab get into melee range with Denka this turn without dashing?)

(Correct. Silvian is in metal armor, so Denka gets to make 2 shocking grasps against him with advantage. After that, she is paralyzed due to failing the wis save. After that, Scarab goes, and then back to Denka and Swigg)

(You have 25 ft of movement, correct? It takes 27.5 to reach Denka, since Silvian's space is difficult terrain, unfortunately. Although I'm not sure how working with half-squares works).

(Ok, so if you do not have 10 ft of movement you cannot move past Silvian, so Scarab cannot reach Denka without dashing)

(Guess I'll go now, since Denka hasn't posted yet.)

Scarab moves to H4. He then draws his wand, and a mass of sticky webbing shoots out to cover the ground (web, DC 15). (Area of Effect: F to J, 6 to 10)

Guess im going to retroactively redo my attacks against the invisible bard.

1 Attack: 25 Damage: 6

2 Attack: 18 Damage: 4

And now im paralyzed.

 Swigg will continue his Heat Metal riff 12

He then moves to M9  and plays a lullaby only Silvian and Scarab can hear Sleep 24 centered at H7 (or wherever it needs to be to only hit Scarab and Silvian.)

Swigg ends his turn at L10 

Mansion Round 3/4:

Denka moves forward, seeking Scarab, but bumps into an invisible presence at F4. With a right and left hook she electrifies the invisible Tiefling, but is greeted with two icy bursts as she strikes his armor of agathys (Denka takes 20 cold damage). Then her muscles all seize as he paralyzes her.

Scarab steps up and sprays a thick, white goop out of his "wand", coating the area (web only covers a 20 ft cube, so you get a 4x4 area on the map).

Swigg concentrates on an image of his friend burning and Scarab writhes in pain as his armor heats again. Swigg's soothing melody is heard by Silvian and Scarab, but they both just yawn and continue on with their business.

(Denka is up, you are currently paralyzed and at the end of your turn make a wis saving throw)

(wait... how does a bard have over 33 hp with a d8 hit die? Is is con mod +3?) 

(Yes, but also he has armor of agathys so Denka's attacks didn't hit his HP)

(OH SHIT I forgot!) 

Scarab's concentration: 22

The webbing disappears.

Am i still paralyzed since Scarab failed his concentration save ?

(Silvian is the one paralyzing you, so you still need to attempt a save.)

(Also, I think Scarab falls asleep.)

Ah, was thinking it was scarab for what ever reason.

Well since its the only thing i can do, i will make my wisdom save at the end of my turn.  11

(Ah yes with that heat metal damage Scarab does fall asleep, the web also disappears regardless of the con save since you are asleep)
