Surfacers are confusing, but fortunately that doesn't make it any harder to shoot them.

Let's see how much damage he can do before they can see again. And Woljif's right; empowered first.

Working together, they can drop the cleric inside a round. The other two are mostly focused on using their crossbows, but apart from the one lucky shot on the Tien woman, they don't seem to be having much luck with them.

When the blindness wears off, she surveys their current positioning, then shakes her head. "Disappointing. The crusaders appear to have positioned themselves such that a Color Spray would be counterproductive. In the absence of other alternatives, an Acid Splash will suffice."

"I'm not a crusader, lady!"

"...Aren't you? You've been... crusading... with us."

That sounded like "break my hands" to Blai.

He gets the real one and not one of the illusory doubles! 

"Ow!" Grimace. "Unfortunate. Despite initial appearances, this form of Iomedaean displays similar issues to Kenabres's inquisitors with regards to targeting non-hostiles."

"Lady, if you want my advice, it would probably help not to go around dressed like a Baphomet cultist."

Is now a good time to shoot an arrow at the scary guy with the mace without getting stabbed for it?

No.

Ideally it would never be a good time for that. Does he have to kill the madwoman to keep her from Acid Splashing his people?

Nope! He has successfully rendered her unable to perform somatic components. 

Great. Any more cultists up?

One of the archers is still standing, barely.

He should stop that. Unless he'd like to choose this moment to surrender!

He does not. He goes down.

"Interesting! Despite remarkably poor ability to avoid collateral damage, the crusaders were nonetheless able to overpower the cultists. More data is necessary to determine whether this is the result of superior skill, superior numbers, superior tactics, or some other cause. Recording data may be difficult due to damage to the primary experimenter's fingerprints." She pauses. "Now that that's over with, would you be willing to participate in an experiment on theological knowledge among crusaders?"

"Ma'am, I am going to need your formal surrender immediately. Do you need me to explain what that means?"

"According to my research, requests for surrender, when obeyed, precede torture in nearly one-in-two cases! If that is not what you meant, you will need to clarify."

"We're not going to torture you!"

"We are not going to torture you," Blai echoes. "Surrendering means you agree to follow our instructions and not attack us or resist non-torture attempts to secure you and transport you."

She gives him a look like she thinks he is very stupid. "Of course I am willing to agree not to attack you! If I intended to attack you, I would not have prioritized avoiding collateral damage with my Color Spray. Whether I am willing to follow your instructions depends on the content of those instructions."

Camellia inspects her rapier thoughtfully.

"You were not at the time particularly clear about who you were intending to target any of these spells with, when we came across you you were wearing a symbol of Baphomet, and if you do not surrender we are going to have to continue to have a fight, which you will lose, because you have broken hands."
