I'm pretty sure the general physical description won't change, though. Just trying to keep things interesting. There is some chance that Xiao Lung might not have those weapons, or Xiao Hu (who I haven't actually worked on at all), might appear different.
Starman: Okay, no worries. I'm sorry to see you go, though.
2,000,000 lb rock: That would cost 250,000 GP. At most, you will face an 800,000 lb rock (which will do 10d6 per 10 ft per square, or 200d6 from 200 ft). That's nothing to be afraid of .
Forgot to mention: If someone DOES drop a big frickin' rock, it's only going to work once. Hethas will nerf it after that, probably with divine featherfall or something.
