I need some clarification about how many attacks a monster can do and the way this is specified in the monster description.
I noticed that these entries are separated by "," or "and". Is there any difference or do both have the same meaning?
Then if a monster has multiple attacks (natural or not), how many of them can it do in a stabdard action?
For example, a dragon has bite, 2 claws, 2 wings, tail slap. In a full attack it gets 6 attacks, no questions, but what about in a standard action (let's say after a move)? Does it still have 6 attacks or must it choose only one of them?
And what about a Marilith? With:
+1 longsword +24/+19/+14/+9 (2d6+8/17–20), 5 +1 longswords +24 (2d6+4/17–20), tail slap +17 (2d6+3 plus grab) or 6 slams +22 (1d8+7), tail slap +17 (2d6+3 plus grab)
... I'm more confused. Does this mean that it has ( 4 attacks (+24/+19/+14/+9) and/or 5 attacks (+24) and/or tail slap ) or ( 6 slams and/or tail slap )?
Generally I don't always understand where/when the "," is an and or an exclusive or.
