So, you want to understand Opportunity Attacks (AoO) in Dungeons & Dragons 5th Edition? You’ve come to the right place. An opportunity attack is a key mechanic that allows characters to punish enemies who carelessly leave their reach during combat. It’s a tactical cornerstone, impacting movement, positioning, and overall strategic decision-making on the battlefield.
The fundamental rule is simple: You can make an opportunity attack when a hostile creature that you can see moves out of your reach. To execute the attack, you use your reaction to make one melee attack against the provoking creature. Crucially, the attack occurs right before the creature leaves your reach. Think of it as a parting shot, a swift consequence for a hasty retreat.
Key Components of Opportunity Attacks
Let’s break down the elements that make up this crucial combat action:
-
Trigger: A hostile creature you can see moves out of your reach. This is the heart of the rule. No sight, no AoO. “Out of your reach” means the creature physically leaves the area you can attack without using specific actions to prevent it.
-
Reaction: Making an opportunity attack uses your reaction. You only have one reaction per round. This means you must carefully choose when to unleash your AoO. Used your reaction for Shield? No AoO for you this round.
-
Hostile Creature: It must be an enemy. Your allies can frolic in and out of your reach without fear of reprisal.
-
Melee Attack: You make a single melee attack. This is important. You can’t suddenly decide to cast Fireball as an opportunity attack. It’s a weapon swing (or an unarmed strike).
-
Timing: The attack happens before the triggering creature leaves your reach. This detail matters for effects that might alter the situation, such as the Haste spell granting another action.
-
Provoking Creature: This creature is the one triggering the AoO when it leaves your reach.
Exceptions and Circumstances
While the core rule is straightforward, several circumstances can modify or negate opportunity attacks:
-
The Disengage Action: Using the Disengage action prevents a creature from provoking opportunity attacks for the rest of its turn. This is the primary way to safely move away from an enemy.
-
Incapacitation: If you are incapacitated, you cannot take reactions, so you cannot make opportunity attacks. Think of conditions like being stunned, paralyzed, or unconscious.
-
Invisibility: If you cannot see the creature moving, it does not provoke an opportunity attack. Hello, Invisibility spell!
-
Reach Weapons: If you are wielding a reach weapon (like a glaive or halberd), your reach extends further. Thus, a creature might provoke an opportunity attack when leaving that extended reach.
-
Special Abilities: Some creatures or classes have abilities that either prevent them from provoking opportunity attacks or grant them unique ways to make them. For example, the Mobile feat allows you to move away from a creature you attacked without provoking an opportunity attack from that creature.
Strategic Implications
Understanding opportunity attacks is essential for effective combat strategy. Here’s why:
-
Control: Opportunity attacks help you control the battlefield. By threatening enemies who try to move past you, you can force them to stay engaged or risk taking damage.
-
Positioning: Be mindful of your positioning. Don’t give enemies free opportunity attacks by carelessly moving away.
-
Protection: Protect your squishy allies! By positioning yourself strategically, you can discourage enemies from targeting them.
-
Action Economy: Using the Disengage action costs an action, which can be a significant trade-off. This forces players to make difficult choices during combat.
Frequently Asked Questions (FAQs)
Here are some commonly asked questions about opportunity attacks, along with detailed answers:
1. Can I grapple as an opportunity attack in 5e?
No, you cannot. The rules require you to use the Melee Attack action to initiate a grapple, and you can only take actions on your turn, not as a reaction.
2. Can I cast a spell as an opportunity attack?
No, you cannot cast a spell as an opportunity attack. Opportunity attacks are limited to making a single melee attack.
3. How many opportunity attacks can I make per turn?
You are limited to one reaction per round, which means you can only take a single opportunity attack per round, regardless of how many creatures provoke them.
4. Does invisibility prevent opportunity attacks?
Yes, it does. Opportunity attacks require you to see the creature moving. If a creature is invisible, you cannot see it, and therefore it does not provoke an opportunity attack from you.
5. Can I make opportunity attacks while grappled or restrained?
Yes, you can. Being grappled or restrained does not prevent you from taking reactions or making attacks, including opportunity attacks. However, remember that the restrained condition imposes disadvantage on attack rolls.
6. Can I make multiple attacks of opportunity if several enemies move out of my reach?
No. Even if several enemies provoke opportunity attacks, you can only use your one reaction to make one opportunity attack per round.
7. What exactly triggers an opportunity attack?
The trigger is a hostile creature you can see moving out of your reach. It’s all about the act of leaving the space within your melee attack range.
8. How do opportunity attacks work with reach weapons?
Opportunity attacks with reach weapons trigger when a creature leaves the extended reach granted by the weapon. If you are wielding a glaive, a creature provokes an AoO when it moves out of your 10-foot reach.
9. Does drawing a weapon provoke an opportunity attack in 5e?
No, drawing a weapon typically does not provoke an opportunity attack in 5e. Drawing or stowing a weapon is usually part of your movement or action.
10. Do opportunity attacks get advantage if I have advantage on attacks?
Yes, opportunity attacks are still attack rolls, so if you have advantage on attack rolls for any reason (such as the enemy being prone and you are within 5 feet of them), you also have advantage on opportunity attacks.
11. Can a Steel Defender make opportunity attacks?
Yes, a Steel Defender can make opportunity attacks, using its reaction.
12. Can I make opportunity attacks in darkness?
You can only make opportunity attacks against creatures you can see. If you cannot see the creature due to darkness, you cannot make an opportunity attack.
13. Can I use Reckless Attack when making an opportunity attack?
No, the Reckless Attack feature of the Barbarian class specifies that it must be used on your turn. You cannot use it when making an opportunity attack.
14. Does pushing an enemy with a spell like Thunderwave trigger opportunity attacks?
Typically, no. Forced movement does not trigger opportunity attacks, as the creature is not moving “of its own volition.”
15. Does jumping trigger opportunity attacks?
Jumping can trigger opportunity attacks if the jump results in the creature moving out of your reach. Think of it as moving between cubes of space rather than just squares on the ground. If the jump takes them far enough to fully leave your reach, they trigger an AoO.
Conclusion
Mastering opportunity attacks is essential for any D&D player who wants to be a tactical force on the battlefield. By understanding the rules, exceptions, and strategic implications, you can use this powerful mechanic to control the flow of combat and protect your allies. Now go forth, and make those enemies pay for their hasty retreats!
