An example of the monster I have a question over is a Crab, Giant. It's Melee looks like this:
2 claws +4 (1d4+2 plus grab)
I am wondering about the "2 claws" part. Does that mean the crab gets to strike twice with both its claws as a full round action, thus possibly rolling 1d4+2 twice? Or is the stat block saying the crab attacks with both of it's claws and together does only 1d4+2?
Also, what if the Melee looked like this:
2 claws +4 (1d4+2 plus grab), bite +5 (1d8+4)
Does the above melee line allow for three full attacks as a full round action? Or only two attacks?
I just started DMing for the first time and am trying to become prepared.
