When you want to grab a creature, you can use the Attack action. The target of your grapple must be no more than one size larger than you, and it must be within your reach.
Using at least one free hand, you try to seize the target by making a grapple check, a Strength (Brawn) check contested by the target's Strength (Brawn) or Dexterity (Acrobatics) check (the target chooses the ability to use). You succeed automatically if the target is Incapacitated. If you succeed, you subject the target to the Grappled condition. You can release the target whenever you like (no action required).
You can attempt to drag the grappled creature. When doing so, the creature's weight is doubled when calculating your Carrying Capacity and encumbrance, while moving the creature.
A grappled creature can use the combat action Escape Grapple to try to escape the grapple.
A grapple is lost if the grappler is Incapacitated.
Grappling Actions
When you grapple a creature, you can with a Combat Action make a grapple check to attempt one of the following actions, to wrestle with it further:
Bind
You try to bind your target’s weapon. If you succeed, your opponent may not use the bound weapon. You may end the bind at any time.
Choke
You attempt to choke a creature that is of a size equal to or smaller than you. If you succeed, the creature immediately begins choking. To maintain the choke, you must use a combat action each turn.
Crush
You attempt to use your brute strength to squeeze the life out of your opponent. If you succeed, the creature takes your Strength modifier as bludgeoning damage. If you have another extra free hand, you may use it to add 1d4 damage.
Lift
You attempt to lift up the creature. The creature's weight is doubled when calculating your Carrying Capacity and encumbrance, unless you use another free hand.
Meat Shield
You attempt to use the creature as cover, increasing your cover level by one (From none, to half, to three-quarters, to full).
Restrain (Wrestle)
You try to pin a creature grappled by you. If you succeed, the creature is Restrained until the grapple ends.
Throw
You attempt to throw a creature. If you succeed, you throw the creature up to your throwing distance, knocking the creature Prone. The creature's weight is doubled, when calculating your throwing distance for it, unless you are lifting the creature, as specified by the Lift grapple action.
