8/14/2014 - I'm trying a couple things here. First, I want to show a bad-ass Fantasy character with a disability, representing that disability mechanically, but with a positive tone overall. Second, it occurs to me that the Charging Rhino ability can be expressed as a cost rather than a restriction, and that the Goblin War Drums ability is as good on small creatures as it is on big ones (for different reasons).
I worked hard to find compelling Fantasy flavor that is empowering rather than objectifying. I won't know how well or poorly I did unless someone with personal experience happens upon this. Even then, a single person couldn't speak for everyone with one arm, and there would likely be disagreement both within and without the group. My hope is that a majority in both groups would feel good about this representation, of course, but if they don't, I would love to hear their feedback on what they didn't like and what they would have.
Also, I'm pretty fond of these abilities on two-drops.
