=====Starting a Grapple=====
To start a grapple, you first needs to grab and hold your opponent. Attempting to start a grapple is the equivalent of making a melee attack. Follow these steps.
#Attack of Opportunity: You provokes an attack of opportunity from the opponent you are trying to grapple as with normal unarmed attack. Each point of damage received from the attack of opportunity is a penalty to your grab attempt.
#Grab: You make a melee attack to grab the opponent against his Defense. If you succeed, you damage your opponent and proceed to step 3. 
#Hold: As a quick reaction, your opponent can try to break free from your grapple. The opponent must beat your Stability to break free with a Melee, Strike, Sweep or Escape Artist check. If your opponent check failed, he his hold and may lost his current action if they are restricted by the hold. If successful, the opponent break the hold, continue his current action and you are not grappling anymore.
#Maintain the Grapple: To maintain the grapple, you must move into the target’s square as an instantaneous reaction. Moving, as normal, provokes attacks of opportunity from threatening enemies, but not from the grappled opponent. 
If you can’t move into the opponent’s square, you can’t maintain the grapple and must immediately let go of the target. To grapple again, the character must begin at step 1.
