Another Grappling Question

[Waffle2121]

I understand the wording behind why Grappling cannot be initiated as an Attack of Opportunity when other Combat Maneuvers (Sunder/Trip/Disarm) can.

My question is if there exists any way I could make it so? Is there a weapon that grants a free Grab or Grapple on a successful hit? Is there a Feat hidden somewhere which allows you to make a Grab/Grapple as "part of a melee attack?"

A friend and I have been kicking around the idea of a Combat Maneuver/Grapple based character and think this could make him or her even better!

Hamatula Strike is going to be your best bet...

More information on the build would be nice, wildshape could grant grab, synth summoner could get it as well I believe (been awhile since I looked at it though).

Also this is probably more appropriate in the advice forum. This is more 'how can I get this to work?' than a question on how the rules work ;)

Blade of Binding grants grapple on hit, but i doubt your friend would use greatsword

8th level Tetori monks get the Grab special at 8th level when they spend a ki point, spending 2 lets them grab creatures larger than themselves.

The other common one is to take turtle style and turtle clutch which allows you to make a grapple check at -2 when a creature misses you.
