A'kin stands up again, and offers the patch to Ian.
"To activate it, you need to wear the patch - either on your skin or on your garments -, focus on it and speak out loud its symbol. The sound of this one is Sal Athaum."
When Ian takes the patch, A'kin turns to Ophelia and the others again, waiting for an answer.
A'kin grabs for the patch, pulls on it, and with a loud SCRUTCH he tears it out of the robe.
"Safe to remove, I assume," he says with a smile. "The illithids I have known so far wouldn't have used magic, no matter how powerful. It's like asking if a deva would use magic that burns the souls of innocents."
He ponders for a moment, then adds, "Unless our friend here was on his way to become an illithid lich, but he seemed not powerful enough for that. Maybe he was just at the beginning of his path."
