I'm sure this is a dumb question, but I can't seem to figure it out the proper way to handle monsters with multiple special attacks. If a monster (say the Behir) takes a full-round attack action, do they get all of their attacks AND special attacks?
For example, if in one round, the Behir attacks, successfully grapples (grab, free action), can it also use it's breath attack?
OR
If it attacks, but is already grappling a previously grappled opponent, can it also use it's Rake attack, and it's breath attack? It doesn't say in the universal rules if these are free actions, swift actions, move actions, or standard actions.
However if the Behir has greater grapple he could grapple as a move action and take a standard action to use his breath weapon (please note the standard Behir doesn't have the feats for this, but a specific Behir might).
Now the only place where I would see a question is with the grab ability which seems to suggest you can maintain the grapple outside of the normal grapple rules provided you take a -20 on the check.
The creature has the option to conduct the grapple normally, or simply to use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its CMB check to make and maintain the grapple, but does not gain the grappled condition itself.
Please note that as long as the grapple is maintained you get the rake attacks for free each round (they do not require an action). Also Constrict deals damage each round that the grappling creatures succeeds on its grapple check.
A creature with this special attack can crush an opponent, dealing bludgeoning damage, when it makes a successful grapple check (in addition to any other effects caused by a successful check, including additional damage). The amount of damage is given in the creature's entry and is typically equal to the amount of damage caused by the creature's melee attack.
A creature with this special attack gains extra natural attacks under certain conditions, typically when it grapples its foe. In addition to the options available to all grapplers, a monster with the rake ability gains two free claw attacks that it can use only against a grappled foe. The bonus and damage caused by these attacks is included in the creature’s description. A monster with the rake ability must begin its turn already grappling to use its rake—it can’t begin a grapple and rake in the same turn.
Swallow whole is another option that can be had with a grapple check for the Behir:
If a creature with this special attack begins its turn with an opponent grappled in its mouth (see Grab), it can attempt a new combat maneuver check (as though attempting to pin the opponent). If it succeeds, it swallows its prey, and the opponent takes bite damage. Unless otherwise noted, the opponent can be up to one size category Smaller than the swallowing creature. Being swallowed causes a creature to take damage each round. The amount and type of damage varies and is given in the creature’s Statistics. A swallowed creature keeps the grappled condition, while the creature that did the swallowing does not. A swallowed creature can try to cut its way free with any light slashing or piercing weapon (the amount of cutting damage required to get free is equal to 1/10 the creature’s total hit points), or it can just try to escape the grapple. The Armor Class of the interior of a creature that swallows whole is normally 10 + 1/2 its natural armor bonus, with no modifiers for size or Dexterity. If a swallowed creature cuts its way out, the swallowing creature cannot use swallow whole again until the damage is healed. If the swallowed creature escapes the grapple, success puts it back in the attacker’s mouth, where it may be bitten or swallowed again.
Thanks everyone! I guess I was missing the whole business about the 'grappled' condition, and didn't realize special abilities are (almost) always standard actions.
