A grappled creature is restrained by a creature, trap, or effect. Grappled creatures cannot move and take a –4 penalty to Dexterity. A grappled creature takes a –2 penalty on all attack rolls and combat maneuver checks, except those made to grapple or escape a grapple. In addition, grappled creatures can take no action that requires two hands to perform. A grappled character who attempts to cast a spell or use a spell-like ability must make a concentration check (DC 10 + grappler's CMB + spell level), or lose the spell. Grappled creatures cannot make attacks of opportunity.

A grappled creature cannot use Stealth to hide from the creature grappling it, even if a special ability, such as hide in plain sight, would normally allow it to do so. If a grappled creature becomes invisible, through a spell or other ability, it gains a +2 circumstance bonus on its CMD to avoid being grappled, but receives no other benefit.

Marius, Scholai Armsmaster Says: Once a creature is grappled, you have several options on what to do with them:

  • Move at half speed, carrying the target with you.  If you try to drop them into something dangerous like a trap, they get a free escape attempt at a +4 bonus.  Still worth it.

  • Damage the creature with unarmed or a natural attack.

  • Attempt to pin the target.

  • Let go.
