I rather enjoyed the fact that the Nameless One relied on knives, rings, and tattoos (and his own invulnerable, scarred-up body) to survive instead of using conventional armor and a sword. The reason why a ring or a tattoo could be so powerful was part of the game: namely,
beliefs are what make anything powerful or even possible. The mechanism which made the Nameless One immortal (SPOILER:
Ravel's clever way of making other souls die in his place so he could live) was remarkable and certainly not conventional, and it was all part of the same landscape. The other characters walking around Sigil were also pretty unusual. The Planes are strange to begin with, so I was glad to see strange things.
