Khessa repeats the winning strategy used last time: the fight, she protects herself with a Blade Ward.

As soon as Ozus brings in the new 'guests', the blonde arcane warrior attacks the Cultist, welcoming him with a first descending slash of her [item]Greatsword[/spell], aimed at his head, immediately doubled by a lunge at breast height.

Khessa's Multiattack with Greatsword:

Attack 1: 28 Damage: 16 (slashing) or 4 if missed (thanks to Graze property)
Attack 2: 23 Damage: 8 (slashing) or 4 if missed (thanks to Graze property)

Watching the cultists turn the corner, Ozus allows himself a chuckle. "Well that went smoother than expected. Anyway..."

He turns to the remaining ghoul. "Hey big and ugly, catch." He says casually, five streaks of flame launching at it. Unfortunately, he cant help but flinch at his own flames, causing two of the bolts of fire to go wide.

A: Casting scorching ray at level four

Attack: 20 total Damage: 5 fire damage

Attack: 25 Damage: 6 fire damage

Attack: Nat 1, total of 10

Attack: 11

Attack: 13 Damage: 9

wow okay the dice are not my friend today

BA: Conjure Pact weapon

The first cultist through the door is almost immediately cut down by Khessa, he now has gaping wounds and is struggling to stay upright. The other cultist is quite surprised as well...what do the rest of you do?

The ghoul stumbles back after taking the three scorching rays to the face. It's barely standing now, and is wide open for another attack.

Tristan:

Tristan moves to engage the other cultist, slashing twice with his crystal Longsword!

Crystal Longsword:  Attack: 12 Damage: 20

Crystal Longsword:  Attack: 18 Damage: 12

Wash, rinse, and repeat?

Should look familiar . . ..

Use Steady Aim

Basic Attack (Advantage from Steady Aim) with Moon-Touched Shortsword: 14  Piercing Damage: 7  Sneak Damage: 7

Second Attack with Moon-Touched Shortsword: 19  Second Attack roll in case of Advantage (Previous hit grants Advantage) 22  Piercing Damage: 10  Sneak Damage in case of Advantage: 8

Savage Attack reroll of Base Damage on first hit w/primary weapon: 8 

Off-Hand Attack with Dagger of Venom: 15   Second Attack roll in case of Advantage (Previous hit grants Advantage) 16   Piercing Damage:  5   Sneak Damage in case of Advantage:  7

Assuming 14 misses.  Assuming 19 hits.  Not really willing to guess on the 15/16.

0+18+(0 or 12)  

EDIT:  Oops.  I see that I should have specified a target!  Since I already know the dice rolls, let's do this:  Odd is ghoul, even is cultist.

2

(Actually, 14 hits! These regular cultist guys are pretty weak-ish.)

The cultists fall under the onslaught, and Ozus is left with a nearly dead ghoul.

"Nothing personal, you understand. Just good business"  Ozus says, finishing the ghoul off with an eldritch blast

Attack:22 Damage: 3

Attack:26 Damage:9

Once the second group has been neutralized, Khessa suggests: "Now shall we go back to the library and eliminate the remaining ones? Even if you've already proven yourself convincing twice in a row, Ozus, I doubt they'd believe you a third time without hesitation..."

"Sound logic, at least."

(Ozus is in the library, dealing with the ghoul. He sent two cultists to y'all XD)

Oh, sorry, coming to the library, then, I guess...

The library is clear, the former prisoners have stayed behind with Tristan's Trusty Steed, and the five of you have gathered again. Where to next?

"Well that was easy." Ozus examines the coffin. "Anyone recognize this name? Ayren Griffenstone."

"Good job, 'Tooth' Ozus!" Khessa pats the other on the shoulder "If it was easy, it was mostly thanks to you!"

The blonde arcane warrior takes her time examining the books in the library, hoping to find useful arcane knowledge; but in the meantime she hears the name 'Ayren Griffenstone' and, after thinking about it, replies: "It's not someone on our 'wishlist'... but these Cultists could very well have kidnapped other unfortunate citizens".

Naero  

Spid-ero climbs down from the ceiling, taking care not to be trampled. He skillfully runs up Ozus' robes and retakes a place on his shoulder. "Convincingly done. A ruse to be remembered" spid-ero says in his squeaky arachnid voice. "Presumably we head back down the hallway? I can try to sneak under the doors to have an idea of what lays behind if you all wish."

"The idea of ​​sneaking under the doors to know in advance what lies behind is a great one, Naero!" Khessa was distracted for a moment from her examination of the books upon hearing the proposal. "By exploiting this expedient and the trick of the 'Tooth', we could perhaps simplify many other subsequent 'encounters' as well."

Tristan:

“In that case, I shall take rear guard position so as not to give away our ruse,” says Tristan, “And KJ will keep guarding the freed prisoners.”

For safety, Tristan will be at the end of the marching order just in front of their rescuees, and KJ will be behind them.  That way hopefully they are protected from both sides.

"Each door in order, at least until we get close to the corner, then?"
