[B]Improved Grab[/B]
If a creature with this special attack hits with a melee weapon (usually a claw or bite
attack), it deals normal damage and attempts to start a grapple as a free action without
provoking an attack of opportunity. No initial touch attack is required. Unless otherwise
noted, improved grab works only against opponents at least one size category smaller than
the creature. The creature has the option to conduct the grapple normally, or simply use
the part of its body it used in the improved grab to hold the opponent. If it chooses to do
the latter, it takes a -20 penalty on grapple checks, but is not considered grappled itself;
the creature does not lose its Dexterity bonus to AC, still threatens an area, and can use its
remaining attacks against other opponents. [COLOR=SlateGray]A successful hold does not
deal any extra damage unless the creature also has the constrict special attack. If the
creature does not constrict, each successful grapple check it makes during successive
rounds automatically deals the damage indicated for the attack that established the hold.
[/COLOR] Otherwise, it deals constriction damage as well (the amount is given in the
creature’s descriptive text). When a creature gets a hold after an improved grab attack, it
pulls the opponent into its space. This act does not provoke attacks of opportunity. It can
even move (possibly carrying away the opponent), provided it can drag the opponent’s
weight.
