Grabbing Objects

A character can also use disarm to snatch away an object worn by a target. Doing this works the same as a disarm attempt (see above), except for the following.
Attack of Opportunity: If the target's attack of opportunity inflicts any damage, the attempt to grab the object automatically fails.
Modifiers: If the object is well secured or otherwise difficult to grab from the target, the target gets a +4 bonus. On the other hand, if the object is poorly secured or otherwise easy to snatch or cut away, the attacker gets a +4 bonus.
Failed Attempts: Failing an attempt to grab an object doesn't allow the target to at-tempt to disarm the character.
