Improved Grapple( Deities and Demigods, p. 51)
The deity is skilled in martial arts that emphasize holds and throws.
Improved Unarmed Strike (PH) ,
Earth's Embrace (OA) ,
If the deity hits with an unarmed strike, it deals normal damage and can attempt to start a grapple as a free action without provoking an attack of opportunity. No initial touch attack is required. The deity can deal normal damage while grappling, rather than subdual damage, without suffering a penalty on its grapple check.
Characters without this feat make a melee touch attack to grab their opponent and provoke an attack of opportunity doing so. They also suffer a -4 penalty on their grapple checks when trying to deal normal damage in a grapple.
