Passing through the connecting hall, without ringing any of the bells will bring you into a large common room where you find two mages and five cult fanatics

mage M1 init 12

cult fanatic C5 init 3

Talorin furrows his brow at Umerto's rudeness to Bridgette, though he's thankful Necyra stepped in to alleviate the situation.

He however is intrigued at the mentions of Vecna and Kas. Vecna... was that the guy that went insane- no that's a different guy. Maybe the orphan kid that- nah. Though maybe it applied to Vecna too. He agrees Necyra's desire to learn more, even if Umberto was a bit of a snoble. [[ snob + noble ]]

[[ For me my primary knowledge of Vecna comes from Stranger Things when Eddie was talking about the lore of the liche lord. ;p ]]

He listens to what Yurgojin says, "If these cultists are worshipping this Vecna then it may prove pertinent to our knowledge of them." He asks Umberto, "Any common symbols of this Vecna?"

Initiative: 18+1 = 19

Yurgojin initiative: 14

Bridgette Initiative: 9

Necrya Initiative: 11

Trystane Initiative: 16

The lead mage (M1) shouts, "Memories of Vecna, attack the intruders!"

A defiant cult fanatic (C4) responds, "Oxtu, please call us followers or even just cultists. Anything is better than memories."

Oxtu (M1) replies, "Address me as Teeth, for I am the Teeth of Vecna"

Voices are raised in a rally cheer, mixed with some groans and sneers.

Mysleen gets to roll or she takes DM init roll of 22

Round 1
Mysleen init 22 << your turn
C4 init 22
Talorin init 19, Trystane Init 16 (Group 1) << your turn
C5 init 17 (lowering to init 15), C2 init 15 (Group 2)
Yurgojin init 14 (lowering init 11), Necrya Init 11 (Group 3)
M1 init 11
Bridgette Init 9
M2 init 6, C3 init 4, C1 init 3 (Group 4)

Trystane focuses on Oxtu, the self-proclaimed 'Teeth of Vecna.' A fierce growl escapes his lips, and he bares his own teeth in response. With a powerful leap, Trystane launches himself toward the mage. Mid-air, his transformation begins. His body contorts and grows, his muscles bulging and expanding as he gains eight inches in height, reaching an imposing eight feet tall. His features twist into a more hideous form, reminiscent of his troll heritage. His hair grows wilder, and his hands morph into clawed appendages, razor-sharp and deadly. Landing before Oxtu with a thunderous impact, his clawed hands swipe at the mage with brutal precision, aiming to rend flesh and bone. The growl that escapes his throat is deep and primal, echoing through the room as he strikes. 

Move: Jump towards M1 (20 feet long/7 feet high if space permits, 40 feet total movement)
Bonus: Hybrid Transformation (lasts one hour)
Action: Two unarmed strikes @M1, hit 14 and 15, for 14 and 9 magical slashing damage, respectively

Round 1
Mysleen init 22 << your turn
C4 init 22
Talorin init 19, Trystane Init 16 (Group 1) << your turn
C5 init 17 (lowering to init 15), C2 init 15 (Group 2)
Yurgojin init 14 (lowering init 11), Necrya Init 11 (Group 3)
M1 init 11
Bridgette Init 9
M2 init 6, C3 init 4, C1 init 3 (Group 4)

I totally messed up Init. Here is a do-over

Targets 1d6
1-Bridgette, 2-Mysleen, 3-Necrya 4-Talorin, 5-Trystane, 6-Yurgojin
C4 starts combat casting spiritual weapon on 5
C4 lunges forward to use his dagger on Yurgojin, Attack: 22 Damage: 3

Trystane, Jump towards M1 (20 feet long/7 feet high if space permits, 40 feet total movement), bonus action Hybrid Transformation (lasts one hour)
Two unarmed strikes @M1, hit 14 and 15, for 14 and 9 magical slashing damage, respectively

M1 casts shield as a reaction to make his AC 12 become 17. Both attacks will miss

Round 1
C4, Trystane
Talorin, Yurgojin, Necrya, Bridgette, Mysleen << your turn
M1, M2, C1, C2, C3, C5

(I'll take your init roll Ascher.)

Mysleen had just woken up from her nap for this fight, so she's a little cranky. She will cast dissonant whispers on Mage 1 for 11 psychic damage, and as a bonus action will use her Mantle of Majesty to cast command on Mage 2. She will issue the command "Grovel!"

(Sorry for not paying attention to everyone's posts, I was busy for a while.)

You still need to roll attack and damage.

Talorin gets an uneasy feeling with two mages amongst the enemies. But as the first shields himself he delights at the opportunity to see about striking them ineffective while the fanatics are dealth with. He grabs the crystal around his neck and chants an invocation, loosing two bolts of magic from his head at the mages.

Action: [spell]Raulothim's Psychic Lance[spell]
Twinned to hit both Mage 1 and Mage 2
Damage: 5+2+6+2+3+2+6 = 26 psychic damage
Save DC 19
Failed Save: Full damage and incapacitated until start of Talorin's next turn
Successful Save: Half damage

Will use a reaction to either counterspell a counterspell. Or, if not counterspelled, to Silvery Barbs a successful save (priority M1 if both save) and give the advantage die to Yurgojin

Of course, this is going for 5-Trystane, Spiritual Weapon Attack: 15 Damage: 7 

Yurgojin will star going after the closest "memory" and start trying to remove some of there minions out. BA: activating Flame Tongue 

Attack 1: crit (first roll so regardless of advantage) Damage: 11+ 8 plus wepon plus 17 sneak attack plus 13 fire damage = 48 damage

Attack 2: 26 to hit, damage 10 weapon plus 5 fire = 15 total

Rowdy's initiative: 18

Rowdy will run forward and position himself 10 feet in front of Mysleen, and take the Dodge action.

Unfortunately, I think when you cast command from a bonus action, it must be paired with a cantrip to allow you to cast more than one spell per round. If I'm wrong, please let me know.

1) cast command with vicious mockery
2) dissonant whispers and another bonus action

 (That's my bad. I'll take option 1 for 6 psychic damage, WIS save 17.)

My apologies with the init confusion. I'll use this post to try to get everyone back on track.

(No Counterspell'ing this round from the Mages, they are too startled to react, "How did all these casters sneak in here?")
