The short, direct answer is: yes, you can use Action Surge to cast two spells on the same turn, provided you adhere to specific limitations of the bonus action spell rule. Action Surge grants you an additional action on your turn, allowing for an extra action in the same round. Crucially, this extra action can be used to cast another spell. However, the key constraint involves bonus action spells and their impact on other spellcasting during that turn. Let’s break this down to fully understand the mechanics.
Understanding Action Surge and Spellcasting
Action Surge, a core feature of the Fighter class, is a powerful ability that allows you to take one additional action on your turn. This extra action can be used for virtually anything you can do with a standard action, including attacking, dashing, or, most importantly for our discussion, casting a spell. However, the magic system in Dungeons & Dragons 5th Edition (5e) has specific rules regarding spellcasting in the same turn, and understanding these rules is crucial for any spellcaster seeking to maximize their effectiveness with Action Surge.
The Bonus Action Spellcasting Rule
The primary rule affecting spellcasting with Action Surge is the so-called bonus action spell rule. This rule states that if you cast any spell (leveled or cantrip) as a bonus action, the only other spells you can cast that turn must be cantrips with a casting time of 1 action. This limitation applies regardless of the source of the bonus action; whether it’s from a spell like Misty Step, a class feature, or Metamagic such as Quickened Spell.
Action Surge and Two Leveled Spells
The most significant takeaway for our question is that Action Surge allows you to bypass this restriction when it comes to casting two leveled spells. Since the extra action gained from Action Surge is a full action and not a bonus action, it does not trigger the bonus action spell rule. This means that you can cast two spells of 1st level or higher on the same turn, using your standard action and the additional action from Action Surge. For example, a Fighter multiclassed with a full spellcaster could cast Fireball with their initial action and then cast Lightning Bolt with the action from Action Surge.
The Importance of Action Economy
Action economy is fundamental to 5e. Having the ability to use two actions to cast two high-level spells can provide a significant tactical advantage in combat. This combination turns a fighter into a powerful burst caster for a single turn, and you must utilize this wisely when in dire situations. It’s especially effective when dealing with multiple enemies or needing a quick burst of damage.
Frequently Asked Questions (FAQs)
Here are 15 frequently asked questions to further clarify how Action Surge interacts with spellcasting:
1. Can Action Surge double attacks?
Yes, if you take the Attack action, you can attack as many times as you can normally. So if a fighter at level 5 (where they get Extra Attack) uses Action Surge and uses both actions to take the Attack action, they’re attacking a total of four times.
2. Can you cast Eldritch Blast twice with Action Surge?
Yes, you can cast Eldritch Blast twice, provided you have two actions to spend. If you take the attack action to cast the spell twice, it will fire multiple beams at a time at higher levels and allow for extra damage.
3. Can you cast two Fireballs with Quickened Spell?
No, Quickened Spell does not remove the limitations imposed by casting a spell as a bonus action. If you use Quickened Spell to cast Fireball as a bonus action, you cannot cast any other spells except a cantrip that has a casting time of 1 action.
4. Can you cast two Fireballs with Action Surge?
Yes, you can cast two Fireballs with Action Surge, provided you have the spell slots to do so. The bonus action spell limitation is avoided, allowing you to use both actions for levelled spells.
5. How many spells can you cast with Action Surge?
You can cast two leveled spells using Action Surge, provided you haven’t cast any other spells as a bonus action during the same turn. You can also use action surge to cast a spell and then use your regular action to cast another spell, or you can use two action surges to cast two spells.
6. Can you use Action Surge more than once per turn?
No, you can only use Action Surge once per turn.
7. Why is Eldritch Blast considered the best cantrip?
Eldritch Blast is unique among damage cantrips because it gives additional attacks as it scales, instead of just additional damage dice. Furthermore, Warlocks can greatly increase the power of Eldritch Blast with Invocations such as Agonizing Blast and Repelling Blast.
8. How many times can you use Action Surge per rest?
Once you use the Action Surge feature, you must finish a short or long rest before you can use it again. At 17th level, Fighters can use it twice before a rest, but still, only once per turn.
9. Do you get a second bonus action with Action Surge?
No, Action Surge does not grant you a second bonus action.
10. How does Action Surge work with dual wielding?
Action Surge gives you another action that turn. Two-Weapon fighting allows you to spend a bonus action on an extra attack when you take the Attack action. You can spend the bonus action during either one of those attacks, but you can’t spend it on both because you only have one bonus action.
11. Can you cast two cantrips on the same turn?
Yes, you can cast two cantrips if you have enough actions for them. But if you cast a leveled spell on the turn, the only cantrip that you cast on the same turn must have a casting time of 1 action.
12. Can you cast two spells in one turn with Quickened Spell?
No, you can cast a quickened spell as a bonus action, and then only a cantrip as a regular action.
13. Can you use Quickened Spell with Eldritch Blast?
Yes, via Quickened Spell, Eldritch Blast can be cast twice within the same turn (once as a bonus action and another as an action), or it could be cast in addition to another damaging spell.
14. Does Haste stack with Action Surge?
Yes, the only limitation Haste applies is to the specific action it gives, which is limited to one attack only. You can do anything you’d normally be capable of with your other actions, including the one from Action Surge. This includes using Extra Attack. Haste’s action is limited to what it says on the tin: particularly in this case a single attack.
15. Can you cast a cantrip as a bonus action?
They can be cast as bonus actions through the Sorcerer’s Metamagic (Quickened Spell), and as reactions through the War Caster Feat, but otherwise, cantrips always cost an action to cast.
Conclusion
In summary, Action Surge allows you to cast two spells of 1st level or higher in the same turn, providing significant tactical flexibility and damage potential. It’s crucial to always remember the bonus action spell rules to maximize the effectiveness of your spells, especially when pairing bonus action spells with the power of Action Surge. Properly utilizing these features can turn the tide of battle in any D&D 5e encounter, making a Fighter and spellcaster multiclass, or any class with Action Surge, a force to be reckoned with.
