summon coin

Right. And by some odd coincidence, might that option just happen to involve the coin in my basement?
"Why do you continue to be so stubborn about this, my host?" Lasciel demanded, her voice tight with frustration. "Taking up the coin would not enslave you. It would not impede your ability to choose for yourself."
Not at first, no. But it would finish up with me enslaved to the true Lasciel, and she knew it.
"Not necessarily," she said. There was a tone of pleading to her voice. "Accommodations can be reached. Compromises made."
Sure, if I'm willing to go along with her every plan, I'm sure she'd be quite agreeable.
"But you would be alive," Lasciel cried.
It didn't matter, given that the coin was buried in the stone under my lab anyway.
"Not an obstacle, my host. I can teach you how to call it to you within a few seconds."
Thud-thump : 1:31.
A thud from behind me. Footsteps. The ghouls. They were coming. I could see part of Marcone's face, twisted in agony under Vittorio Malvora's psychic assault.
"Please," Lasciel said. "Please, let me help you. I don't want to die."
I didn't want to die, either.
I closed my eyes for another second.
Thud-thump : 1:30.
It took an effort of will, and what seemed like several moments of effort, but I managed to whisper aloud, "No."
"But you will die," Lasciel said, her voice anguished.
It was going to happen sooner or later. But it didn't have to be tonight.
"Then quickly! First, you must picture the coin in your mind. I can help you - "
Not like that. She could help me.
