What are the Rules for AoO in 5e?

Opportunity Attacks (AoO) are a crucial aspect of combat in Dungeons & Dragons 5th Edition (5e). These attacks allow a character to strike an enemy that is moving away from them, providing a chance to take advantage of an opponent’s momentary lapse in attention. In this article, we will delve into the rules governing AoO in 5e, covering the triggers, restrictions, and exceptions that players and Dungeon Masters (DMs) need to know.

Triggers for Opportunity Attacks

An Opportunity Attack can be triggered in two situations:

• Moving out of your reach: When a hostile creature moves out of your reach, you can make an Opportunity Attack against it.
• Provoking an Opportunity Attack: Certain actions, such as disengaging from combat or moving through a threatened area, can provoke an Opportunity Attack.

Restrictions on Opportunity Attacks

While Opportunity Attacks can be a powerful tool, there are some restrictions to keep in mind:

• Reaction: Opportunity Attacks are a reaction, meaning they can only be taken after the triggering event has occurred.
• Limited to one per turn: A character can only make one Opportunity Attack per turn.
• Only against hostile creatures: Opportunity Attacks can only be made against hostile creatures, not against friendly creatures or NPCs.

Exceptions to Opportunity Attacks

There are a few exceptions to the rules governing Opportunity Attacks:

• Disengaging: When a creature disengages from combat, it is not considered to be moving out of your reach, and therefore does not trigger an Opportunity Attack.
• Flying: Creatures that are flying do not trigger Opportunity Attacks when moving out of your reach, as they are not considered to be moving horizontally.
• Certain abilities: Some abilities, such as the Flyby ability, allow creatures to move through a threatened area without triggering an Opportunity Attack.

Avoiding Opportunity Attacks

There are a few ways to avoid triggering an Opportunity Attack:

• Disengage: By disengaging from combat, a creature can avoid triggering an Opportunity Attack.
• Use ranged attacks: Creatures that use ranged attacks do not trigger Opportunity Attacks when moving out of your reach.
• Use abilities that ignore Opportunity Attacks: Some abilities, such as the Moonbeam spell, ignore Opportunity Attacks.

Conclusion

Opportunity Attacks are an important aspect of combat in 5e, providing a way for characters to take advantage of an opponent’s momentary lapse in attention. By understanding the triggers, restrictions, and exceptions to Opportunity Attacks, players and DMs can use this mechanic to add depth and excitement to their games. Remember to always keep in mind the limitations and exceptions to Opportunity Attacks, and to use them strategically to gain an advantage in combat.
