I have a few first I will start with grab the power says that you automatically do the natural attack used to start the grapple in damage to the target after a successful maintaining roll. Does this stack with using your turn to harm the enemy (single natural attack)if this doesn't stack with harm does it stack with moving or pinning your opponent?
With greater grapples you can do two maintaining actions in a turn does that mean on the round after you grapple an opponent you can both pin and tie them up?
As maintaining an grapple is a standard action does master of maneuvers flurry allow you to do it alongside a full attack as maintaining a grapple is a standard action combat maneuver and master of maneuver flurries allow you to do a number of standard action combat maneuvers along with your full attack.
If an enemy is tied up do they count as helpless for coup de gras attacks?
