The typical hollow are using the zombie "undead fortitude" ability, or whatever it's called. Hate that thing.
I'm having plenty of fun, though. Grouping up with Tosti was definitely the highlight of the game for me so far, so I'm hoping to fall back in line with the others so that I can see more soapstone signs, and have my own be seen. :) However, even the solo play has been pretty fantastic. I think Harmia's about due to finally die, though, especially with how I've been rolling lately.
