Do you intend to add self-mutilation to Tides of Numera like in Planescape: Torment during Ignus "lessons"?
Probably asking this way too early, considering that you are still in pre-production. Still, this is very important to me!
Backstory (because my audience includes non-Torment fans as well):
In Planescape: Torment, you played the role of an immortal who lost his memories each time he died. Because you're immortal, we were able to include moments like plucking out your own eye and replacing it with a demon's, or having a powerful wizard (Ignus) teach you how to use powerful fire magic by, literally, burning the lesson into your body.
In Torment: Tides of Numenera, you don't play an immortal, but the castoff shell of a man who cheats life by jumping from body to body (he doesn't realize the bodies he leaves behind wake up and have their own lives after he leaves them).
So you're not immortal, but the castoffs are quite hard to kill. We haven't drilled down into the details of every area yet (which is where a lot of this stuff will surface), and I'm not allowed to give spoilers, but there is definitely the opportunity for PST-like moments like Ignus and Ei-Vene.
Got a question for me? Ask me anything.
