Opportunity Attacks & Reactions ⚔️


🔁 What Are Reactions?

Reactions are special responses that you can take outside your turn, usually triggered by specific events.

  • You only get one reaction per round.

  • After using it, you regain it at the start of your next turn.

  • Common reactions include Opportunity Attacks, Counterspell, or Shield.

Examples:

  • A Fighter uses Opportunity Attack when an enemy runs away.

  • A Wizard casts Counterspell when a rival mage begins casting.

  • A Paladin uses Divine Smite on a reaction-based hit. ⚡

Reactions keep combat dynamic — players can respond to danger even when it’s not their turn.


🗡️ Opportunity Attacks (OA): Don’t Run From Me!

An Opportunity Attack happens when a creature you can see moves out of your reach.
It’s your chance to take a quick swing before they flee!

Rules for Opportunity Attacks:

  • Use your reaction to make one melee attack.

  • Triggered only when an enemy leaves your reach, not when they enter it.

  • Requires no special ability — all characters can do it.

  • The attack happens before the target leaves your reach.

Example:

  • An Orc runs past your Fighter to reach your Wizard.

  • Your Fighter uses their reaction to make a melee attack.

  • If the hit lands, the Orc takes damage before getting away. 💥


🛡️ Avoiding Opportunity Attacks

You can’t always fight back, but you can avoid triggering them:

  • Disengage Action: Move safely without provoking attacks.

  • Teleportation: Doesn’t trigger OA (e.g., Misty Step).

  • Being Forced to Move: Shoved, pulled, or pushed? No OA triggered.

  • Reach Weapons: Extend your control area — great for locking enemies down!


💡 Tactical Tips

  • Control the battlefield: Place melee fighters between enemies and your casters.

  • Use OA to punish poor positioning.

  • Save your reaction wisely — you might need it for a spell or defense.

  • Feats like Sentinel or War Caster make reactions even more deadly.
