As a Standard Action, you may attempt to Disarm an opponent, forcing them to drop one weapon (or object) that they are holding.
Making a Disarm Attack[]
Make a normal melee attack roll against your opponent, who gets a +10 bonus to their Reflex Defense during this Action. If your opponent is holding the weapon with more than one hand, you take a -5 penalty on your attack roll to Disarm them, per additional hand grasping the weapon.
If the attack succeeds, your opponent is Disarmed. If you successfully Disarm your opponent with an Unarmed Attack, you can take the Disarmed weapon (or object). Otherwise, it falls on the ground at your opponent's feet (inside their Fighting Space).
If your Disarm attack fails, your opponent can immediately make a free attack against you.
Improved Disarm[]
If you have the Improved Disarm feat, you get a +5 bonus on your melee attack roll to Disarm an opponent, and your opponent doesn't get to make a free attack against you if your Disarm attempt fails.
Ranged Disarm[]
If you have the Ranged Disarm Talent, you can attempt to Disarm your opponent with a ranged attack. If the attack fails, your opponent doesn't get to make a free attack against you.
