How Many Times Can a Wizard Cast a Cantrip? The Unlimited Power of 0-Level Spells
A core element of any D&D wizard’s arsenal, cantrips are often misunderstood despite their fundamental importance. The short, straightforward answer to how many times a wizard can cast a cantrip is: an unlimited number of times per day. Unlike higher-level spells, cantrips do not consume spell slots, making them a reliable resource for any wizard, regardless of their current magical reserves. Wizards, like other spellcasting classes, can cast a cantrip every turn they have an action available, and there is no limit to how many different cantrips they can cast.
The Magic Behind Cantrip Flexibility
The magic of cantrips lies in their nature as spells that are fixed in the caster’s mind. This means that after learning a cantrip, a wizard can repeatedly perform the actions and incantations necessary to produce its effect without expending any magical resources. This allows for constant utility, minor magical offenses, and creative problem-solving throughout a long adventuring day.
Action Economy & Cantrips
The primary limitation on how often a wizard can cast a cantrip comes from the action economy within a combat round. Generally, a wizard has one action per turn, which is usually spent casting the cantrip. However, some class features and magic items can grant bonus actions, which can be used to cast a spell, but if that spell is not a cantrip the action must be a cantrip spell. Thus, a wizard can potentially cast two cantrips in one turn: one as a regular action and one as a bonus action if a feature is available to grant them. If the wizard casts any other spell (1st level or higher) that requires a bonus action, they can still cast a cantrip with their standard action.
No Cooldown, No Downtime
Unlike some game mechanics, there is absolutely no cooldown period or recharge time for cantrips. As long as a wizard has an action available, they can cast any cantrip they know. This makes them a reliable tool for both combat and utility purposes.
Frequently Asked Questions About Cantrips
Here are fifteen frequently asked questions to further clarify the nuances of cantrip usage:
1. Are Cantrips Spells?
Yes, absolutely. Cantrips are classified as 0-level spells. They are a subset of all spells, distinct due to their unlimited usage and non-expenditure of spell slots.
2. Do Cantrips Require Preparation?
No, cantrips do not need to be prepared daily like higher-level spells. Once a wizard learns a cantrip, they can cast it at will. This differs from other spells that must be specifically prepared or memorized after a long rest.
3. Can a Wizard Change Their Cantrips?
Generally, cantrips are permanent, and cannot be exchanged after a wizard learns them. However, Tasha’s Cauldron of Everything introduced an optional rule allowing wizards to change a cantrip after completing a long rest, giving more flexibility.
4. Can You Cast Multiple Cantrips in One Turn?
Yes, under certain conditions. You can cast a cantrip as an action and another cantrip as a bonus action if you have features like a quickened spell from the sorcerer’s metamagic. However, if you cast a non-cantrip spell with your bonus action, your action can still cast a cantrip.
5. Can You Use Metamagic on Cantrips?
Yes. Sorcerers with Metamagic can absolutely apply these abilities to their cantrips. For example, the “Quickened Spell” metamagic can turn a cantrip into a bonus action, which would then allow the sorcerer to cast another cantrip as an action on the same turn.
6. Do Cantrips Scale in Power?
Yes, the damage or effectiveness of most cantrips increases as you level up. This scaling is usually based on your character level, not your spellcasting level, ensuring cantrips remain relevant throughout the game. Typically, the dice rolled for damage, such as a d6 or d8, will increase at levels 5, 11, and 17.
7. How Long Do Cantrips Last?
The duration of cantrips varies but is usually either instantaneous, lasting for one round, one minute, ten minutes, or one hour. The exception to this is “Encode Thoughts” which has a duration of eight hours.
8. Do Cantrips Break Invisibility?
It depends on the cantrip. If the cantrip includes an attack roll or requires you to cast a spell it will end your invisibility spell. Some DMs may interpret certain cantrips that have an obvious impact on the environment as breaking invisibility, even if they do not technically break the spell according to rules as written.
9. Are Cantrips Worth It?
Absolutely. Cantrips provide reliable, unlimited access to magical effects without expending spell slots. They can be used for offense, defense, utility, and roleplaying, making them essential for all spellcasting classes.
10. What Is the Best Cantrip for Damage?
The definition of “best” depends on your specific needs and play style. However, generally, Eldritch Blast (for Warlocks) is often considered the most powerful damage-dealing cantrip, followed by Fire Bolt or Ray of Frost for wizards. For support or control, cantrips like Mind Sliver or Vicious Mockery are excellent for applying debuffs to enemies.
11. Can You Cast Cantrips During a Long Rest?
Yes, but with a caveat. Casting spells, including cantrips, for more than one hour during a long rest will prevent you from gaining the benefits of a long rest. This is due to the fact that casting spells is mentally taxing, and disrupts the restful state required to fully benefit from a long rest.
12. Can Wizards Copy Cantrips?
Wizards cannot copy cantrips from scrolls into their spellbook through standard methods. This is because cantrips are considered learned magic that does not require spellbooks like spells of the 1st level or higher. If a wizard wanted to learn additional cantrips they would have to take a class feature, multiclass into another caster class, or use a feat to learn more.
13. Do Cantrips Cost Any Resources?
No. Cantrips are free to cast. They don’t cost spell slots or any other type of resource, meaning a wizard always has access to their cantrips.
14. Are Cantrips Automatically Heightened?
Yes, cantrips automatically scale as your level increases. Their effects, such as damage dice, improve at character levels 5, 11, and 17, making them more powerful as you progress.
15. How Many Cantrips Does a Wizard Start With?
A Level 1 Wizard begins with three cantrips from the wizard spell list, in addition to learning additional cantrips when leveling up. This starting amount can be altered by their race, feats, and any homebrew rules that their DM decides to implement.
Conclusion: The Indispensable Tool
Cantrips are much more than just filler spells; they are an indispensable tool for any wizard. The fact that a wizard can cast a cantrip an unlimited number of times, as long as they have the appropriate actions, makes them one of the most essential elements of magic in D&D. By using them strategically, wizards can conserve their spell slots for more significant encounters while still impacting the world around them at all times.
