The biggest change is that after playing a few session and running a dungeon dive that was very combat heavy my players and I started noticing that the Small But Vicious Dog table (while cool and awesome) bogged down things when it was being used as a creatures lifeline when they reached zero HP.
Midway through the dungeon dive I changed it to at zero HP- roll a Con check. If you fail you pass out and are bleeding out. If you succeed you stay conscious, but suffer -2 to all rolls.
Critical hits are double damage and that’s when you consult the Small But Vicious Dog Chart.
I did a little rearranging/clarifications to abilities as well.
Enjoy! Hope peeps like it. I’m glad my group is.
