"They are Orks. What are the odds that they would bump into, or even less care about a bunch of invisible camouflaged servo skulls? They don't even bleed when stabbed; only the most bored among their bloodthirsty numbers would even care about them." Adrianne argued back at the krieger.

From all her experience with the Orks, she had learned that they liked to fight. Especially against things that fought back, and bonus points if those things could bleed and scream!
Back when she was attached with the Imperial Guard, she had more than once visited previously-overrun bunkers belonging to the guard, where every guardsman, scribe and tech priest had been brutally mauled and destroyed, yet servo skulls and even one of the tech-priest's own little machines had been left unmolested, apparently not even having been worth the greenskin's attention before they charged towards the next big fight.

Then again, she had also heard of greenskins found hoarding looted imperial tech, so she supposed it wasn't a foolproof plan...

"Could even rig one of hte nearby building's support pillars to go at a switch of a button."

In that moment, Adrianne's violet eyes passed over from the standing pile of anthropomorphized scavanged imperial armor that was Vala, and over towards the epitome of gloom in the room that was the masked krieger.

"That sounds like a job for the group's resident krieger." Adrianne commented as she eyed Asnsgar through his mask.
"Ansgar, how much explosives did you bring with you?"
