Sorry if this is a real basic question. I just recently started playing Pathfinder about a week ago and I'm still learning the ropes. So you may see me post other simple questions in the coming days, but anywho.
When I'm looking at any NPC or monster and their hp shows as, 15 (2d8+6).
Does that mean its base hp is 15 and every level after that I would roll 2d8+6 to determine what it would be the following level?
