The question of which spells can be cast as a bonus action is a crucial one for any D&D 5th edition player looking to optimize their spellcasting efficiency. In short, a spell with a casting time explicitly listed as “1 bonus action” can be cast as a bonus action. This is a core mechanic within D&D, and understanding it is paramount to strategic gameplay. These spells are typically swift and often support other actions, allowing for a diverse and powerful combination of moves within a single turn. This contrasts with the standard “1 action” spells that take a more significant part of your turn to perform. Not all spells, however, can be cast as a bonus action, which can lead to confusion, this guide will help clarify all the information you need about this subject.
Understanding the Core Mechanic
The fundamental rule is that a spell’s casting time, as detailed in its description, dictates how it’s cast. If a spell’s description reads “Casting Time: 1 bonus action,” it must be cast as a bonus action. This is not something that the player can choose; it is a property of the spell itself. This specificity prevents players from arbitrarily casting any spell as a bonus action. This is a major facet of the Action Economy in D&D 5e, and learning how to manipulate it is a key element to any successful character build.
The Importance of the Action Economy
The Action Economy is a crucial concept in D&D 5e. Each turn, a player typically has one action, one bonus action, one move, and potentially a reaction. Utilizing each of these optimally is essential for character effectiveness. Bonus action spells are designed to integrate with your other actions and movements, maximizing what you can do within a single turn. These types of spells are usually smaller and focus on buffs, debuffs, or other supportive actions.
Restrictions on Bonus Action Spellcasting
A key restriction is the “bonus action spell rule.” If you cast a spell as a bonus action, the only other spell you can cast on that turn must be a cantrip with a casting time of 1 action. This is important to remember, otherwise, it could lock you out of using a useful and powerful spell on your turn. You cannot cast two leveled spells (a non-cantrip spell) in a single turn, and bonus action spells contribute to this restriction.
Frequently Asked Questions (FAQs) About Bonus Action Spells
To help clarify this complex topic even further, here are some Frequently Asked Questions and their in-depth answers.
1. Can I use a bonus action spell as an action?
No, unless the spell’s description explicitly states otherwise or there is some other outside mechanic to turn it into an action, you can not. A spell with a casting time of a “1 bonus action” can only be cast as a bonus action according to D&D 5e rules. There isn’t a way to bypass this restriction without homebrew rules set by a DM.
2. Can you cast two cantrips if one is a bonus action?
Yes, you can cast a cantrip as a bonus action if it has a 1 bonus action casting time, and another cantrip as your action. This leverages the bonus action and maximizes your spellcasting potential. However, neither can be a spell above the cantrip level.
3. Can a wizard cast a leveled spell as a bonus action?
Generally, no. Wizards, or any class for that matter, can only cast leveled spells as a bonus action if the spell’s casting time specifically states “1 bonus action”. A wizard could cast a leveled spell as their action and then a cantrip as their bonus action, but not the other way around. There are outside features from specific classes like the Sorcerer’s Metamagic that can make other spells be cast as a bonus action, but this is the exception, not the norm.
4. Is there a rule on only one spell per turn?
There is a specific restriction on casting multiple non-cantrip spells. You can cast one leveled spell (a non-cantrip spell) and one cantrip in one turn, or a cantrip as your action and a spell as a bonus action, or just a cantrip and one leveled spell, but not two leveled spells. If either spell, or both, have a casting time of a bonus action, you can not cast a spell above the level of a cantrip with your action.
5. Is Healing Word a bonus action?
Yes, Healing Word is a spell with a casting time of 1 bonus action. This is a crucial part of its utility as a quick, ranged heal that can fit into most turns. However, you would have to use a cantrip on that same turn if you cast it with your bonus action.
6. Can Eldritch Blast be a bonus action?
Normally, no. Eldritch Blast is a cantrip that is cast using your action. However, some class features and invocations for the warlock can modify how you cast Eldritch Blast. For example, some could potentially make it a bonus action through specific class features or spells.
7. Does Vicious Mockery use a bonus action?
By itself, no. Vicious Mockery is a cantrip with a casting time of 1 action. However, some subclasses of the bard may allow you to cast Vicious Mockery as a bonus action a limited amount of times, or even as a reaction. This is a unique feature for bards of that subclass.
8. Can you cast Hex and Eldritch Blast?
Yes, you can cast Hex as a bonus action, and then cast Eldritch Blast as your action, or the other way around. Both spells can coexist within the action economy because one is a bonus action and the other is an action.
9. Can you counterspell a bonus action spell?
Yes, you can counterspell a bonus action spell, as there are no restrictions that prevent this within the rules of D&D 5e. Counterspell has a casting time of 1 reaction, which means that you can use it on any turn, not just your own, and that does not interfere with your own turn, or the spell that is being cast with the bonus action.
10. What are some common bonus action spells?
Common bonus action spells include:
- Healing Word (Cleric, Bard)
- Shield of Faith (Cleric, Paladin)
- Shillelagh (Druid, Ranger)
- Hex (Warlock)
- Misty Step (Sorcerer, Warlock, Wizard)
11. Are there any class features that modify how bonus actions can be used?
Yes, several class features can modify how bonus actions can be used. Examples include:
- Cunning Action (Rogue): Allows the rogue to Dash, Disengage, or Hide as a bonus action.
- Bardic Inspiration (Bard): The bard uses a bonus action to grant a Bardic Inspiration die to an ally.
- Combat Wild Shape (Circle of the Moon Druid): This ability allows the Druid to turn into an animal as a bonus action.
- Eldritch Knight (Fighter Archetype): Can summon their bonded weapon as a bonus action.
- Metamagic (Sorcerer): Allows some sorcerers to cast certain spells as a bonus action
12. Does throwing a dagger use a bonus action?
The act of throwing a dagger can be incorporated into your action, and a second dagger can be thrown with a bonus action using two weapon fighting rules. However, throwing a dagger itself is not inherently a bonus action.
13. Can a ranger hide as a bonus action?
Normally no, but at 14th level, some rangers gain the ability to hide as a bonus action. This is a significant perk for stealth-based builds.
14. Is grapple a bonus action?
No. Grappling requires the use of an attack as part of the Attack action. It cannot be performed as a bonus action.
15. What does “Reaction” mean in the context of spellcasting?
Reactions are special actions that a player can take outside of their turn, usually in response to another event. They can only occur when a specific trigger, such as an enemy casting a spell or a creature moving into range, occurs. Reactions are their own unique action.
Conclusion
Mastering the use of bonus action spells is crucial for any player looking to increase their character’s efficiency. By understanding the casting rules, you can maximize your actions in combat and create powerful and versatile builds. Remember the key rule: if a spell has a casting time of “1 bonus action,” it must be cast as a bonus action, and the only other spell you can cast on your turn is a cantrip with a casting time of 1 action. This understanding, along with the nuances of your chosen class and abilities, will give you a significant advantage on your adventures. This makes the action economy and all of the rules surrounding it so important.
