The arcane arts in Dungeons & Dragons (D&D) can be complex, especially when it comes to the rules surrounding spellcasting. A common question that arises among players, particularly those playing Wizards, is: Can a wizard cast a spell and a cantrip in the same turn? The short answer is yes, but with a crucial caveat. The ability to cast both a spell and a cantrip in the same turn hinges on the specific actions taken and the casting times involved. Let’s dive into the specifics to unravel this magical conundrum.
The Core Rule: Bonus Actions and Spellcasting
The key to understanding this lies in the bonus action rule for spellcasting. The Player’s Handbook states that 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 one action. This is where the restriction comes into play.
Think of it this way: your action economy is limited. Casting a spell as a bonus action is essentially “speeding up” a spell. To balance this acceleration, the rules restrict the type of spell you can cast with your action. It must be a cantrip.
So, if you cast a leveled spell like Fireball (which typically requires an action) as a bonus action via a feature like the Sorcerer’s Quicken Spell metamagic, the only other spell you can cast that turn is a cantrip like Ray of Frost or Fire Bolt. This doesn’t prevent you from taking other actions, such as moving, dashing, disengaging, or using an object; it only limits your spellcasting options.
Conversely, if you cast a cantrip as your action, there’s no restriction on casting a spell that takes a bonus action. You can cast Fire Bolt and then Healing Word if you have access to both.
Exceptions and Nuances
There are some exceptions and nuances to keep in mind:
- Action Surge: The Fighter’s Action Surge ability grants you an additional action. However, it doesn’t bypass the bonus action spellcasting rule. If you use Action Surge to cast two leveled spells, and one of those spells used your Bonus Action, you’re still violating the one leveled spell per turn rule.
- Spells with Casting Times Other Than “1 Action” or “1 Bonus Action”: Spells that require longer casting times, such as rituals or spells with a casting time of “1 minute” or longer, are not impacted by this rule.
- Features That Allow Spell Conversion: Some class features, such as certain Cleric domains, might allow you to convert an action into a bonus action, but this doesn’t change the underlying spellcasting rule. If you cast a spell as a bonus action, regardless of how it became a bonus action, the cantrip restriction applies.
- Magic Items: Some magic items might grant you the ability to cast a specific spell as a bonus action. The same rule applies; you can only cast a cantrip with your action.
Practical Examples
Let’s illustrate this with some examples:
- Scenario 1: The Wizard casts Misty Step (a 2nd-level spell that requires a bonus action) to teleport away from danger. They can then cast Fire Bolt (a cantrip that requires an action) as their action. This is perfectly legal.
- Scenario 2: The Wizard casts Fireball (a 3rd-level spell that requires an action) to incinerate a group of goblins. They cannot then cast Healing Word (a 1st-level spell that requires a bonus action) on an ally that was caught in the blast. This is illegal.
- Scenario 3: The Wizard casts Shocking Grasp (a cantrip that requires an action) as their action. They can then cast Healing Word as their bonus action. This is perfectly legal.
- Scenario 4: A Sorcerer uses Quicken Spell to cast Fireball as a bonus action. They can then cast Ray of Frost as their action. Legal because Ray of Frost is a cantrip.
Why This Rule Exists
This rule exists to prevent spellcasters from overwhelming encounters with multiple high-level spells in a single turn. Without this restriction, spellcasters could potentially unleash devastating combinations of spells, unbalancing combat and reducing the challenge for other party members. It ensures that spellcasting remains powerful but requires careful planning and resource management. Understanding the action economy is an important part of successful D&D play, and we should consider it while we’re enjoying our creative problem-solving in this realm of fantasy.

FAQs: Spellcasting and Cantrips
Here are some frequently asked questions (FAQs) to further clarify the rules surrounding spellcasting and cantrips:
1. Can I cast two leveled spells in one turn?
No, generally you cannot cast two leveled spells in one turn. The rule for casting any spell with a bonus action says that the only other spells you may cast that turn are cantrips with an action.
2. Can I cast a spell and then a bonus action cantrip?
A cantrip is a spell that can be cast at will. If you cast any spell – cantrip or not – as a Bonus Action, you can cast another spell on the same turn only if it’s a cantrip with a casting time of one Action.
3. Can I cast 2 cantrips in one turn?
Yes. The rule for casting any spell with a bonus action says that the only other spells you may cast that turn are cantrips with an action.
4. Can I cast a cantrip and a spell with quickened spell?
Yes. Nothing requiring you to do it in either order. The quickened metamagic allows you to cast a spell with a cast time of one action as a bonus action, then cast a cantrip with a cast time of one action.
5. Can a wizard cast a cantrip as a bonus action?
Unless the cantrip specifically has a casting time of a bonus action (or gets changed to have such casting time, it cannot be used as one. If you cast a spell that has a casting time of a bonus action, you can still cast a spell, but that spell has to be a cantrip.
6. Can I cast a cantrip while concentrating?
Yes, you only break concentration if you cast another spell that requires concentration.
7. Can you twin spell a cantrip?
Yes. When you cast a spell that targets only one creature and doesn’t have a range of self, you can spend 1 sorcery point if the spell is a cantrip.
8. Can you quicken fireball?
If a sorcerer quickens fireball first, making it a bonus action, then moves, they are bound by the cantrip rule as they already used a bonus action (fireball), so now their cantrip takes the form of their regular attack.
9. Can I use Eldritch blast as a bonus action?
There are ways. One is to be a Sorcerer, and then either take the the Magic Initiate feat to get Eldritch Blast, or multi-class into warlock, and then use Quicken Metamagic to cast one as a bonus action.
10. What are the rules for casting cantrips?
A cantrip is a spell that can be cast at will, without using a spell slot and without being prepared in advance. Repeated practice has fixed the spell in the caster’s mind and infused the caster with the magic needed to produce the effect over and over. A cantrip’s spell level is 0.
11. Why can’t you cast 2 spells in one turn?
Spells must be cast using their normal casting time unless a specific rule or feature says otherwise. If a spell is cast using a bonus action, you cannot cast any other spell in the same turn except a cantrip cast as an action.
12. Are cantrips free spells?
The term originated from a Scottish word for a magic spell or charm. The term entered the gaming lexicon through Dungeons & Dragons as slang for a spell with a minor effect and no cost.
13. Can you rage and cast cantrips?
You cannot cast spells while you are raging. This includes cantrips. You can, however, cast them while you are not raging.
14. Can fire bolt be a bonus action?
No. Nothing in the rules about casting two spells on a turn changes the casting time for any of your spells. The only cantrips that currently have a casting time of 1 Bonus Action are Shillelagh and Magic Stone.
15. Can a non warlock use Eldritch Blast?
Eldritch Adept feat in conjunction with the Spell Sniper feat allows a non-warlock with Eldritch Blast to augment it in ways they wouldn’t have otherwise.
