Grapple

Attempt to grab a creature or wrestle with it
You can use the Attack action to make a special melee attack, 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 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 (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 (its speed is set to 0).
