What’s the difference between an action and a bonus action in Dungeons & Dragons 5th Edition (D&D 5e)? Simply put, an action is the primary thing you do on your turn in combat, encompassing a wide range of activities, while a bonus action is a secondary, more limited option dependent on your character’s specific abilities, spells, or feats. Every character gets one action and one bonus action each turn, but not every character has something they can do with their bonus action.
Understanding the Core Mechanics
D&D 5e combat is structured around turns within rounds. On your turn, you have several options:
- Action: Your main activity, like attacking, casting a spell, using an item, or dashing.
- Bonus Action: An extra action you can take if you have a feature, spell, or ability that allows it. Not everyone has something they can use a bonus action for!
- Movement: You can move up to your speed. This can be broken up before, after, or between your action and bonus action.
- Reaction: A special response to a trigger, often another creature’s action. You only get one reaction per round, not per turn.
- Free Action: Minor actions like speaking or dropping an item. These are generally handled flexibly.
The key difference lies in accessibility and flexibility. Any character can take common actions like attacking or dodging. Bonus actions, however, are character-specific and often more limited in scope. Think of it this way: your action is the main course of your turn, while your bonus action is a side dish – delicious and helpful, but not always available.
Actions: The Foundation of Your Turn
The action is the cornerstone of your turn. It represents your primary activity. Common actions include:
- Attack: Make a melee or ranged attack.
- Cast a Spell: Cast a spell with a casting time of 1 action.
- Dash: Double your movement speed for the turn.
- Disengage: Prevent opportunity attacks when moving out of an enemy’s reach.
- Dodge: Make yourself harder to hit until the start of your next turn.
- Help: Assist an ally in a task.
- Hide: Attempt to conceal yourself.
- Ready: Prepare an action to be triggered later.
- Search: Look for something.
- Use an Object: Interact with an object, like opening a door or drinking a potion.
Any character can choose one of these actions on their turn. They represent the core options available to everyone in combat.
Bonus Actions: The Character-Specific Boost
Bonus actions are where character builds truly shine. They represent extra, specialized actions that add flavor and power to your character. Unlike actions, bonus actions are tied to specific features, spells, or feats. Common examples include:
- Casting certain spells: Some spells, like Healing Word or Shield of Faith, have a casting time of 1 bonus action.
- Class features: Rogues can use their Cunning Action to Dash, Disengage, or Hide as a bonus action. Barbarians can enter or end their rage as a bonus action.
- Feats: The Great Weapon Master feat allows you to make a bonus action attack if you reduce a creature to 0 hit points with a melee weapon attack or score a critical hit. The Shield Master feat allows you to Shove as a bonus action.
- Two-Weapon Fighting: When you take the Attack action and attack with a light melee weapon that you’re holding in one hand, you can use a bonus action to attack with a different light melee weapon that you’re holding in the other hand.
Because bonus actions are character-dependent, it’s crucial to understand your character’s abilities and how they can be used to maximize your effectiveness in combat.
Timing is Everything
You get one action and one bonus action per turn. You can take them in any order you prefer, unless a specific ability says otherwise. You can move before, between, or after either of your action and bonus action. There is no rule that you must use your action before your bonus action, or vice-versa.
Spellcasting Restrictions
A notable restriction involves spellcasting. If you cast a spell as a bonus action, you can only cast a cantrip with a casting time of 1 action as your action on that turn. This rule prevents characters from casting two powerful leveled spells in a single turn. However, you can use your action to cast a leveled spell and then use your bonus action to cast a cantrip.
Reactions
While not an action or bonus action, reactions are important. You get one reaction per round, which can be triggered by certain events. Common reactions include:
- Opportunity Attack: Make a melee attack against an enemy moving out of your reach.
- Counterspell: Attempt to interrupt another creature’s spellcasting.
- Shield: Cast the Shield spell to increase your Armor Class.
You can use your reaction even on another creature’s turn, making it a crucial defensive tool. Reactions can be triggered even if you used a Bonus Action on your turn.
Frequently Asked Questions (FAQs)
1. How many bonus actions can I take in a turn?
Only one. Even if you have multiple features that grant you a bonus action, you can only choose one to use on your turn.
2. Can I convert an action into a bonus action?
No. There is no general rule that allows you to convert an action into a bonus action. Certain class features or feats might allow you to perform specific actions as a bonus action, but you can’t arbitrarily convert them.
3. Can I take a bonus action if I don’t have anything to use it on?
Yes. You don’t have to use your bonus action if you don’t want to or if you don’t have any available options.
4. Can I cast two spells in one turn?
Potentially, but with limitations. If you cast a spell with a casting time of 1 bonus action, the only other spell you can cast on the same turn must be a cantrip with a casting time of 1 action. Otherwise, you can cast a spell with your action and a cantrip with your bonus action, or vice versa.
5. Does drawing a weapon count as an action or a bonus action?
Drawing one weapon is usually considered part of your movement or action and doesn’t require its own action. However, drawing multiple weapons might require the Dual Wielder feat. Stowing a weapon generally requires an action, but some DMs may allow it as a free action in certain circumstances.
6. Can I use an item as a bonus action?
It depends on the item. Some items, such as potions, require an action to use. Others might have specific rules that allow them to be used as a bonus action. Read the item description carefully.
7. Can I take a reaction and a bonus action on the same turn?
Yes. Your reaction is separate from your action and bonus action. You can use your reaction on your turn or on another creature’s turn, regardless of whether you used your bonus action.
8. Can I move, use my bonus action, and then use my action?
Yes. You can break up your movement and take your action and bonus action in any order you prefer, as long as you meet any specific requirements of the bonus action.
9. Does using Healing Word (a bonus action spell) prevent me from attacking?
Yes, in a way. Since Healing Word is a Bonus Action spell, that means you can only cast a Cantrip as your action on the same turn.
10. If I have two attacks, can I use one as an action and one as a bonus action?
No, unless you are two-weapon fighting with light weapons. The Extra Attack feature allows you to make multiple attacks as part of your Attack action. Your bonus action attack is separate and usually requires a specific feature or feat.
11. Can I use the Ready action with a bonus action?
No. The Ready action allows you to prepare an action to be triggered later. You cannot ready a bonus action.
12. Is shoving a creature an action or a bonus action?
Shoving a creature is part of the Attack action unless you have a feat such as Shield Master that specifically allows you to Shove as a Bonus Action.
13. Can I disengage as a bonus action?
Only if you have a feature that allows it, such as the Rogue’s Cunning Action. Otherwise, Disengaging requires your action.
14. Can I cast a cantrip as a bonus action and then use my action for something else?
No. There are no ways to cast a cantrip as a bonus action unless you’re using an item or feature that lets you cast a specific cantrip as a bonus action. You can cast a levelled spell as a bonus action and then only cast a cantrip with the action.
15. Can I change my mind after declaring my action and bonus action?
That’s up to the DM. In general, you can change your action or bonus action as long as you haven’t yet performed the action and the game state hasn’t changed significantly. However, once you’ve committed to an action and its effects have been resolved, you typically can’t undo it. This keeps gameplay moving and avoids “take-backs.”
Mastering the Action Economy
Understanding the difference between actions and bonus actions is crucial for optimizing your character in D&D 5e. By strategically using your actions, bonus actions, and reactions, you can maximize your damage output, survivability, and overall effectiveness in combat. Pay close attention to your character’s abilities, spells, and feats, and experiment with different combinations to discover what works best for your play style.
