Grapple

You attempt to grab your target and control its movements. The target must be within your Reach, and cannot be more than one size category larger than you. Make a Melee Athletics Attack against your target’s Fortitude DC.

You take a -4 Penalty to your attack roll for every size category your target’s size exceeds yours, and gain a +4 Bonus to your attack roll for every size category your size exceeds your target’s.

You take a -2 Penalty to your attack roll if you are attempting to grapple your target with only one hand.

If you are already Grappling a creature, you can use this action again to maintain the Grapple, resetting the effect’s duration. If you Hit or Critically Hit to maintain a Grapple, the effects listed above occur, and in addition you can choose one of the following effects:

Note that the Grappled condition applies to you as well while you are Grappling a creature.
