- A grappled creature’s speed becomes 0, and it can’t benefit from any bonus to its speed.
- All creatures in the grapple have a disadvantage on Dexterity Saving Throws and their Attack rolls have disadvantage unless they are using a melee with the light property or make an unarmed attack.
- Creatures in a grapple cannot cast spells that require somatic components.
- The condition ends if the Grappler is incapacitated (see the condition).
- If an effect removes the grappled creature from the reach of the Grappler or Grappling effect, they can attempt to escape the grapple at an advantage.
When you want to grab a creature or wrestle with it, you can use an action to initiate a grapple. If you're able to make multiple attacks with the Attack action, this attack replaces one of them.
The target of your grapple must be no more than one size larger than you and must be within your reach. Using at least one free hand, you try to seize the target by making a grapple check instead of an attack roll: a Strength (Athletics) check contested by the target's Strength (Athletics) or Dexterity (Acrobatics) check (the target chooses the ability to use).
If you succeed, you subject the target to the grappled condition (see below). The condition specifies the things that end it, and you can release the target whenever you like (no action required). If the target is larger than you, the roll is made at a disadvantage.
