Opportunity Attacks
Use your reaction to make one melee attack when a hostile creature willingly moves out of your reach. Disengage, teleportation, and forced movement avoid it.
An opportunity attack is a reaction triggered when a hostile creature you can see moves out of your melee reach.
When it triggers: A creature provokes an opportunity attack when it moves out of your reach voluntarily. This includes walking, running, or being pulled by an effect the creature chose (but not forced movement like a shove or thunderwave).
The attack: You use your reaction to make one melee attack against the provoking creature. This happens right before the creature leaves your reach.
One reaction per round: Since opportunity attacks use your reaction, you can only make one per round (your reaction resets at the start of your turn).
Avoiding opportunity attacks:
- Disengage action: Your movement doesn't provoke opportunity attacks for the rest of the turn.
- Teleportation: Teleporting doesn't provoke opportunity attacks because you aren't using your movement.
- Forced movement: Being pushed, pulled, or moved by another effect (without using your own movement) doesn't provoke.
- Rogue's Cunning Action: Disengage as a bonus action.
- Mobile feat: After making a melee attack against a creature, you don't provoke opportunity attacks from that creature for the rest of the turn.
Reach weapons: A weapon with reach (e.g., glaive, halberd) extends your opportunity attack range to 10 feet.
Only creatures can make opportunity attacks. Spell effects that create floating weapons or objects (such as Spiritual Weapon) are not creatures and cannot make opportunity attacks, even though they can make melee spell attacks on your turn.
