Yes, you roll for some cantrips in Dungeons & Dragons (D&D). The need for a roll depends entirely on the specific cantrip being cast. Some cantrips require an attack roll, similar to using a weapon, to determine if you successfully hit your target. Others force the target to make a saving throw against your spellcasting ability. Understanding the difference is crucial for effective spellcasting.
Understanding Cantrips in D&D 5e
What is a Cantrip?
A cantrip is a spell that can be cast at will, meaning it doesn’t require a spell slot and doesn’t need to be prepared in advance (unless the class specifically requires it). Think of them as the bread and butter of a spellcaster, reliable and always available. Repeated practice has etched the spell into the caster’s mind, infusing them with the magic necessary to produce the effect repeatedly. Their spell level is always 0.
Cantrips and Attack Rolls vs. Saving Throws
The core difference lies in how the spell interacts with the target.
-
Attack Roll Cantrips: These cantrips function much like ranged weapon attacks. You, the caster, roll a d20, add your relevant spellcasting ability modifier (Intelligence, Wisdom, or Charisma) and your proficiency bonus (if applicable), and compare the result to the target’s Armor Class (AC). If your result equals or exceeds the target’s AC, you hit! You then deal the spell’s damage or inflict its effect.
-
Saving Throw Cantrips: These cantrips bypass the need for you to make an attack roll. Instead, the target must make a saving throw against your Spell Save DC (Spell Difficulty Class). Your Spell Save DC is calculated as 8 + your proficiency bonus + your spellcasting ability modifier. The target rolls a d20, adds their relevant ability modifier (Strength, Dexterity, Constitution, Intelligence, Wisdom, or Charisma, depending on the spell), and compares the result to your Spell Save DC. If their result is lower than your Spell Save DC, they fail the saving throw and suffer the full effects of the spell. If their result is equal or higher, they succeed on the saving throw, potentially mitigating or negating the spell’s effects.
Examples of Cantrips Requiring an Attack Roll
Several commonly used cantrips require an attack roll. These include:
- Chill Touch: A spectral touch that deals necrotic damage and can prevent the target from regaining hit points.
- Eldritch Blast: A staple for Warlocks, firing beams of force energy.
- Fire Bolt: A classic ranged attack that deals fire damage.
- Produce Flame: Creates a flame in your hand that can be thrown.
- Ray of Frost: A chilling beam that deals cold damage and reduces the target’s speed.
- Shocking Grasp: A melee attack that deals lightning damage and prevents the target from taking reactions.
- Thorn Whip: Pulls a creature closer to you with a thorny vine.
Examples of Cantrips Requiring a Saving Throw
Many other cantrips rely on the target making a saving throw. Here are a few:
- Poison Spray: A noxious cloud that deals poison damage. (Constitution saving throw)
- Sacred Flame: A divine fire that ignores cover. (Dexterity saving throw)
- Toll the Dead: Necromantic energy that deals more damage to injured targets. (Wisdom saving throw)
- Vicious Mockery: Deals psychic damage and imposes disadvantage on the target’s next attack roll. (Wisdom saving throw)
- Mind Sliver: Deals psychic damage and reduces the target’s next saving throw. (Intelligence saving throw)
- Acid Splash: Hurls a bubble of acid. (Dexterity saving throw)
The Power and Versatility of Cantrips
Cantrips are designed to be used frequently. They are invaluable for spellcasters because they provide reliable damage or utility without depleting precious spell slots. Their power scales with your character level, ensuring they remain relevant throughout your adventuring career.
Cantrips and Level Progression
In D&D 5e, cantrips get more powerful at character levels 5, 11, and 17. This scaling usually involves increasing the number of dice rolled for damage (e.g., Fire Bolt dealing 1d10 fire damage at level 1, 2d10 at level 5, 3d10 at level 11, and 4d10 at level 17).
Frequently Asked Questions (FAQs) About Cantrips
1. Can I cast two cantrips in one turn?
Yes, under specific circumstances. If you cast a spell as a bonus action, the only other spells you can cast during that turn are cantrips with a casting time of one action.
2. Are cantrips considered “free” spells?
In a way, yes. They don’t consume spell slots, allowing you to cast them repeatedly without worrying about resource management.
3. Can I use Extra Attack to cast multiple cantrips?
The Fighter’s Action Surge feature allows you to take an additional action, which you can use to cast a cantrip. However, the Bladesinger’s Extra Attack feature allows you to replace one of your attacks with a cantrip casting, not cast two cantrips.
4. Which cantrip deals the most damage?
Eldritch Blast, particularly for Warlocks with the Agonizing Blast invocation, is often considered one of the most potent damage-dealing cantrips. The number of beams increases at higher levels, and each beam can benefit from the invocation’s damage bonus.
5. Do cantrips count as casting spells for other features?
Yes, cantrips are spells. Any feature that triggers upon casting a spell will be triggered by casting a cantrip, unless specified otherwise.
6. Can I “spam” cantrips endlessly?
Yes! That is their intended purpose. You can cast them as much as you’d like, but there may be in-game consequences for doing so, depending on the situation.
7. How long do cantrips typically last?
If not instantaneous, cantrips typically last one round, one minute, ten minutes, or one hour. “Encode Thoughts” is an outlier, lasting 8 hours.
8. Do cantrips break invisibility?
Casting a cantrip does not automatically end invisibility. Whether invisibility is broken depends on the specific effects of the cantrip. Cantrips that involve an attack roll typically end invisibility, as they are considered attacks.
9. Can I put a cantrip in a spell slot?
No, cantrips don’t use spell slots and can’t be upcast.
10. Can I cast cantrips while raging as a Barbarian?
No, Barbarians cannot cast spells, including cantrips, while raging.
11. What is a good cantrip for a High Elf?
Fire Bolt is a versatile and damaging cantrip that is often a good choice for High Elves.
12. Do cantrips get stronger as I level up?
Yes, most damaging cantrips increase in power at character levels 5, 11, and 17, typically by increasing the number of damage dice rolled.
13. Why are they called cantrips?
The term “cantrip” comes from a Scottish word for a magic spell or charm. It entered the D&D lexicon as slang for a minor, cost-free spell.
14. What is the difference between a cantrip and a level 0 spell?
They’re the same thing. Level 0 spells are cantrips. This means you don’t need spell slots to prepare them and you can cast them as often you want.
15. Can you cast 2 Eldritch Blasts twice?
No, you can only cast Eldritch Blast once per action. Action Surge would allow you to cast it again, but not any feature inherent to the cantrip.
Conclusion
Understanding whether a cantrip requires an attack roll or a saving throw is essential for maximizing your spellcasting effectiveness in D&D. Cantrips are powerful tools that every spellcaster should master, providing consistent damage and utility without depleting valuable resources. Don’t underestimate their importance!
