Can you cast a bonus action and action spell in one turn?
The Rule
According to the Basic Rules of D&D (p. 247), a bonus action allows you to perform an action in addition to your primary action on your turn. A bonus action cannot be used as part of your primary action, and vice versa.
The Limitations
If you cast a spell with a bonus action casting time, you cannot take another action in addition to casting that spell, including another bonus action spell. This is explicitly stated in the game rulebook:
"To cast a spell using an action, you can do so as your only action on your turn, even if you could use some other action (such as a bonus action)."
The Confusion Clarified
The game master (GM) must strictly enforce this rule, making it clear to the player that they cannot take additional actions, including casting additional spells, once a spell has been cast with a bonus action. The game master should be cautious and avoid allowing players to assume they can perform additional actions, as this would effectively bypass the limitations outlined in the rulebook.
The Exception: Cantrips
One important exception to the general rule is cantrips with a casting time of 1 action. Cantrips are special spells that can be cast quickly without using up an action on your turn. When using a cantrip, you can cast it without using up your bonus action, allowing you to continue taking additional actions, such as casting another spell with an action casting time, or performing other bonus action abilities.
Examples: Bonus Action Spell Casting vs. Action Spell Casting
| Bonus Action | Action |
|---|---|
| Cast a spell | |
| Perform another ability |
*Bonus Action Spell Casting Example: You cast a Charm Person spell (bonus action casting time) and then attempt to attack with your short sword, but the game master rejects your attack because the spell has already consumed your bonus action.
Action Spell Casting Example: You cast a Mage Armor spell (1 action casting time) and then attempt to attack with your short sword. Because the spell was cast with an action, not a bonus action, you can take additional actions**, including attacking.
Conclusion
In conclusion, casting a bonus action spell and an action spell in the same turn is generally not allowed, unless a cantrip is being used. The game master is responsible for ensuring players abide by the rules, particularly when it comes to actions and spell casting. Additionally, players should always communicate with their game master before attempting to take an action, to ensure clarity on the rules and prevent misunderstanding.
Bonus Actions are Limited
To avoid confusing situations, remember that:
- Bonus actions have limitations: they can be used only once per turn, and not as part of another action (except for cantrips with a casting time of 1 action).
- Action spells take up more resources: casting an action spell consumes your primary action, leaving no additional opportunities for bonus actions.
Understanding these rules will enhance the gameplay experience, fostering greater clarity and communication between the game master and players.
Additional Resources
If you’re still unsure or have further questions, I recommend consulting the official D&D 5E rulebook, the game’s digital versions (e.g., Basic Rules, Monster Manual, etc.), or reputable D&D online resources and FAQs.
