I'm working on a new character concept that's actually a pair of Siamese twins. They share everything from the stomach down, but have separate chests, two arms each, etc.
How would you build this?
I'm thinking Duplication, of course. They have to be able to act somewhat separately. I'd like them to be able to be knocked out separately, but of course they'd suffer penalties when that happened, since each twin controls only one leg. They can't be recombined. BODY damage to one would be BODY damage to the other. Would both forms pay for the Duplication? Is there a limitation for that?
I'm anticipating the 25% differences option--they have a few different skills, but are essentially the same physically.
