In my current game I'm playing a druid who just had his animal companion die. Near the end of it's life, I learned that animal companions are pretty good and grappling tough enemies and making them easier to hit.
I was looking into constrictor snakes and saw that with the grab ability, they get a +4 to start and maintain a grapple. Someone also told me that when you start a grapple, you get a +4 to maintain it. Does this stack with the bonus from the special attack?
