The question of how many cantrips you can use in a single turn is a common point of confusion for many D&D players. The short answer is: you can usually cast a maximum of two cantrips in a single turn, but this requires specific conditions. The interplay between spellcasting rules, particularly those surrounding bonus actions, actions, and leveled spells, can be complex. Let’s dive into the details to ensure you understand when you can channel multiple cantrips and when you’re limited to just one.
Understanding the Core Spellcasting Rules
Before exploring the specifics of cantrip casting, it’s essential to understand the general spellcasting rules in 5th Edition D&D. These rules govern how all spells, including cantrips, can be cast during your turn. The key elements to remember are:
- Actions: Most spells are cast as an action.
- Bonus Actions: Some spells have a casting time of one bonus action.
- Leveled Spells: Spells that require a spell slot are referred to as leveled spells.
- Cantrips: These are 0-level spells cast at will, requiring no spell slots.
The primary rule that governs the number of spells you can cast in a turn is this: you can only cast one leveled spell per turn. This rule applies whether that leveled spell is cast with an action or a bonus action. There is an exception via the Action Surge feature. This is where things get more complex with cantrips and you can cast more than one spell in a single turn if a spell has a bonus action.
The Cantrip Exception
While the rule above sounds restrictive, cantrips introduce a significant exception. You can cast another spell during the same turn, if you have already cast a bonus action spell, and that other spell is a cantrip with a casting time of 1 action. Let’s break this down with examples:
- Scenario 1: One Cantrip Only. You use your action to cast Fire Bolt (a cantrip). You cannot cast any other spell (except for a bonus action spell) this turn.
- Scenario 2: Two Cantrips. You use a bonus action to cast a spell like Misty Step (a leveled spell). You can then use your action to cast Eldritch Blast (a cantrip with a casting time of 1 action). In this case, you have cast two spells, one of which is a cantrip.
- Scenario 3: No Extra Cantrip. You cast Healing Word (a bonus action leveled spell). You cannot then use your action to cast Thunderwave (a leveled spell). You could, however, cast a cantrip using your action after casting Healing Word.
The critical factor here is whether you cast a leveled spell as a bonus action. If you do, the only spell you can cast with your action in the same turn is a cantrip with a casting time of 1 action. If you have not used a bonus action leveled spell you cannot cast more than one spell, even if it is a cantrip.
Action Surge and Cantrips
The Fighter’s Action Surge feature allows them to take an additional action on their turn. This does not circumvent the rules around bonus action spells. This feature can be used to cast another action-based spell, or another action-based cantrip. You may, however, be restricted if you use a bonus action to cast a leveled spell as outlined above.
- Scenario: Action Surge. You cast Misty Step (a bonus action leveled spell). You use your Action to cast Fire Bolt (a cantrip). You then use Action Surge for another action to cast Eldritch Blast (another cantrip) or Firebolt again.
In this case, Action Surge still has the same limitation. You cannot cast more than one leveled spell during your turn, regardless of your action availability.
Frequently Asked Questions (FAQs) About Cantrips
Here are some common questions about cantrips, addressing various aspects of their usage:
1. Can I cast a bonus action cantrip and an action cantrip?
Yes, provided the bonus action spell you are using is a leveled spell. For example, if you cast a leveled spell as a bonus action, you can then use your action to cast a cantrip. However, if you do not use a bonus action spell, you are limited to one spell.
2. Do cantrips have limited uses?
No. Cantrips have unlimited uses. You can cast them as many times as you want per day or per encounter. Unless a specific class feature or rule states otherwise, they are at-will abilities.
3. Can I use two cantrips as two attacks?
No. You cannot use two actions to cast two cantrips in a single turn. If you want to use an action and an additional attack, you can use your action to cast a cantrip and use an additional attack that is not a spell. You may also use additional actions from other class abilities to use a separate action to cast additional cantrips.
4. Are cantrips free spells?
Yes. Cantrips are free in that they don’t cost spell slots and can be cast as many times as you wish. However, they often have lower power than leveled spells and are more suited for utility or consistent, lower-level damage output.
5. How long do cantrips last?
Cantrip durations vary. Most cantrips that are not instantaneous last for one round, one minute, ten minutes, or one hour. There are exceptions, like Encode Thoughts, which lasts for 8 hours.
6. Does a cantrip break invisibility?
Casting a cantrip breaks invisibility, just like casting any other spell.
7. Can I cantrip while raging?
No. You cannot cast any spells, including cantrips, while you are raging. The rage ability specifically prevents spellcasting.
8. What is the most damaging wizard cantrip?
Generally, Fire Bolt is considered one of the most damaging wizard cantrips, dealing 1d10 fire damage and increasing with level.
9. Can I unlearn cantrips?
Typically, no, you cannot unlearn cantrips. Once chosen, you are usually stuck with them. Some variant rules may allow some limited swapping, but this is not the standard in D&D 5e.
10. Are cantrips worth it?
Yes, cantrips are extremely valuable. They provide reliable damage or utility without using spell slots and are crucial for any spellcasting character.
11. Can I use Metamagic on cantrips?
Yes. You can use Metamagic on cantrips. For instance, a Sorcerer can use Quicken Spell to turn a cantrip with a 1-action casting time into a bonus action, allowing them to cast another cantrip with their action, or vice-versa as long as the other is a bonus action.
12. Do I need to rest to use cantrips?
No. You do not need to rest to use cantrips. They are at-will abilities and can be cast as many times as you want without needing to be refreshed by resting.
13. Do I roll to hit with cantrips?
Yes. If a cantrip requires an attack roll, you must roll to hit. You use your spellcasting attack modifier (d20 + proficiency bonus + spellcasting ability modifier).
14. Do cantrips count as spell attacks?
Yes, cantrips are considered spell attacks. They benefit from any modifiers that affect spell attacks.
15. Can I Counterspell a cantrip?
You can not Counterspell a cantrip. Counterspell can not counter a cantrip in the base rules. However, the Clever Counterspell from the School of Abjuration wizard will allow you to use a leveled spell to counter a cantrip if you wish.
Conclusion
Understanding the interplay between actions, bonus actions, leveled spells, and cantrips is vital for effective spellcasting in D&D 5e. While the general rule limits you to one leveled spell per turn, the specific rule of cantrips allows for more versatility and the possibility to cast a second cantrip in a turn. As long as you follow the rules and carefully plan your actions, you can use these powerful spells to your advantage. Use these spells wisely and enhance your gameplay experience!
