Depends on whether any of the crusaders manage to find their footing and decide to specifically go after Nenio while she's down rather than focusing on one of the people who's still a threat; as he's currently positioned, it would be difficult for the succubus to get to Nenio. If no one specifically goes after her, the Count can almost certainly make sure she doesn't actually bleed out while the rest of the party takes down the succubus.

He's not sure if the crusaders will shake off the enchantments when the issuer is dead. It'll depend on the phrasing and so on. But it's a possibility, and keeping just half an eye on Nenio he continues to attack.

How incredibly frustrating! Almost as frustrating as the fact that that swipe that should have gotten him straight through the chest came up against empty air!

Some of her strikes have still found purchase, though, and if the crusaders are on the ground he doesn't need to worry that they'll just stab her again. He channels.

It seems that traditional demonology did not exaggerate the danger of succubi! She will be sure to note that in her Encyclopedia.

Okay, the ground is slippery but it's not that slippery, how about she stands up—

He was sort of hoping to copy this one into his book, but needs must. Suppress Charms and Compulsions.

—That's not her captain, that's a succubus! Stab!

And now you insist on breaking my toys? I suppose I'll have to teach you a lesson about what happens to disobedient mortals.

She reaches out one hand and brushes it against the newly-free crusader's cheek. Vampiric Touch.

(Seelah and Lann will keep up the not-very-injurious stabbing and the somewhat-more-injurious arrowing.)

The thing where casting spells provokes extra swipes applies to the enemy too; he gets another hit in.

Woljif doesn't have another scroll of Suppress Charms and Compulsions, so instead he's going to stand menacingly over the crusaders on the ground and hope this makes them less motivated to get up.

The succubus doesn't make it easy for them; they spend the scroll of Haste and nearly run out Nenio's Displacement before bringing her down, and Daeran burns through two more channels just keeping the people on the front lines alive. Another one of the crusaders manages to get to their feet, though Woljif manages to keep him occupied without actually killing him. When the succubus finally drops, the two armed crusaders who'd been fighting them immediately stop; the confused half-naked guy still looks just as confused.

"Are your wits about you?" Blai asks, catching his breath slightly as he makes really sure she's dead.

"They are now!" says the armed crusader who's still stuck in the Grease spell.

 "I don't see why you had to kill her," says the half-naked guy. "I think she must have been confused, she thought you were cultists."

"...That's a succubus."

 "That's not a very nice thing to say about a nice young woman of her... persuasion."

"Sir, she was not a whore who had wings for unrelated reasons, she was a literal Abyssal demon."

 "But she was so concerned about keeping cultists out of her house..."

"No shit, have you seen the kinds of fights the cultists have with each other? She's probably a Nocticula worshipper who didn't want Deskari's people rifling through her stuff."

Surely no one in his party is going to contradict a little harmless lie, right?

...Is that how that works? It's not like she really knows much about Nocticula.

That's... speculation but it's not like it's technically impossible? This man may just be very dim. "Nenio, can you Detect Magic again please?"

"Detect Magic." She squints around the area for a few moments. "Those three" (she gestures at the armed crusaders) "all have an identical enchantment aura of moderate strength. Naked boy" (gesture) "is under the influence of several overlapping enchantments, most weaker but one of comparable strength. My hypothesis is that those three were under the effect of a Dominate Person, such that the succubus's death caused her control to cease, while naked boy may have been under some form of Suggestion — typically a weaker spell, but one whose effects have been documented as lingering even upon the caster's death."

 "My name is Sigmar."

"That fact is irrelevant to your predicament. Say, would you be willing to describe what forms of contact you had with the succubus — that is to say, the winged woman?"

 "No!"

"Are the other three clear for sure?"
