Nah, only hints for what you need to summon bosses. I figured out on my own what I needed to summon all bosses... except for bonemass. That one had me stumped. I had to look it up. For damage, it was trial and error. I quickly decided arrows were too weak against bonemass, so I melee'd him. A mace was already my standard weapon, so I didn't have to fuss with that.
