Defensive Grapple
From Legends of Cphera
Prerequisites: Improved Grab, Improved Grapple
Cost: 4 General Upgrade Points
When in a grapple you now retain your Agility to AC against opponents outside of a grapple, though your BDB only applies to the opponent you are grappling. You are still considered Open.
In addition, if you are targeted by an external attack of which you are aware, at any time you may as an Immediate Action make a Grapple check for 4 AP. If you beat your opponent then they are now the target of the attack. If you are involved in a grapple with multiple opponents you choose one and only grapple against them for this action.
Normally: You retain Agility and BDB bonuses against opponents you are grappling but not against external foes when involved in a grapple.
