I've always loved the archetype, even before Marco Polo. And I've always wanted to play a character like that. But there was not possible to play a blind character without suffering fully all the rules drawbacks. Now (I was thinking while watching Hundred Eyes on the screen) thanks to the Apocalypse World engine, I think it is quite possible.
Here is what I've got so far:
The Blind Monk
STARTING MOVESHundred Eyes
Even though you’re blind, through discipline and meditation you have heightened your other senses and obtained the ability to feel the general shapes around you and their movements. This allows you to perform general activities, including combat, as if you were able to see. You still can’t tell any details about the shapes until you touch them.
Fists of Fury
Your body itself is a weapon (hand, precise).
Shapeless like water
By emptying your mind, you become shapeless, formless, like water. You adapt to the attacks of your enemies. When wearing no armor and carrying less than your Load, you have armor equal to your WIS as long as you have Chi left.
When you have time and tranquility to center your mind and body lose any Chi you had and gain 3 Chi. You cannot have more than 3 Chi at any time. You can spend a Chi at any time to achieve one of the following effects:
• Block a blow meant for you or someone else (you take half damage).
• Take +1 forward to Defy danger.
• Cross the distance between yourself and a foe, bypassing all obstacles.
• Deal your damage to a foe within reach.
• Leap over or across a physical obstacle.
I'm drawing a lot here from +Sage LaTorra's Battlemind and +Johnstone Metzger's Martial Hero from Class Warfare.
Let me know what do you think, and I hope to post soon more material on this class.
