Can You Stack Action Surge?

Action Surge, a feature introduced in Xanathar’s Guide to Everything, enables a character to take a second action on their turn. But can you really stack Action Surge with another action or feature? Dive into this article to understand the intricacies of combining Action Surge with other magical and non-magical abilities.

Direct Answer

Yes, you can stack Action Surge with other actions, although there are some limitations.

Understanding Action Surge

Action Surge functions by allowing a character to take an additional action of their choice on their turn, in addition to the regular action they can usually take. This additional action can be a standard, bonus, or reaction-based action, depending on how you choose to use the feature.

Stacking Action Surge with Other Abilties

Here are a few scenarios where you might be able to stack Action Surge with other abilities.

• Action Surge and Bonus Action
  • You can take a bonus action that triggers a cantrip with your Action Surge, e.g., casting Hex and then Tenser’s Floating Disk with Action Surge.
• Action Surge and Reaction
  • You can use a reaction ability with your Action Surge, e.g., gaining Uncanny Dodge, Second Wind, and then Action Surge Tenser’s Floating Disk, allowing you to cast four cantrips in your turn.
• Stacking Action Surge with Spontaneous Casting
• Action Surge for casting Eldritch Blast and Teleport in the Hexblade’s Curse (PHB, p124).

Limiting the Stacking Potential – Action Surge’s Original Conditions

Action Surge was designed to allow wizards to take an additional cast in their turn. Limitations were introduced to create balance and prevent players from overwhelming the game with overly powerful combinations. The PHB states:

Wizards can use their cantrips and 1st-level spells without limit, but only casts each 2nd to 5th-level (or higher) spell (not including cantrips and 1st level) once per turn. Action Surge allows (additional) casting of Action Surge spell**, but only casting an additional spell that had already been cast.

Note: Action Surge triggers only when the last spell cast was not interrupted. If the last Action Surge was interrupted, its benefits are lost.

Understanding the limitations of Action Surge can help you make rational decisions when choosing how to utilize your abilities.

Implications for Stacking Spellcasting

This Action Surge capability does not apply to a spell that is spontaneous (PHB, pp 203-204, PHB, p225, PHB, page 235), if that spell is not triggered by the spell effect (PHB, Page 203).

Let’s take an example by combining Eldritch Blast with Feather Fall:

For instance, if you play Eldritch Blast, then Feather Fall, and finally follow with Action Surge Spell Blast, you are already taking the Eldrich Blast action and attempting to cast Feather Fall. When then trying to cast Another Blast with Actions Surge, you would just get the Breach of Spellcasting penalties and not the extra abilities that come with actions Surge.

Tables for Stacking Action Surge

| Spell Tier | Number | Action Surge Capacity | Spell Example |
| —: | —: | ‘: | —: |
| 1st | 1 | Once per turn | Faerie Fire |
| 2nd | 1 | Yes | Web & Invisibility |
| 3-5 | x1 | No | Cast multiple spells, then wait |
| Multiple | x1,y | No | Each slot filled; no stacking |

Exception and Edge Cases

Here are some potential edge cases and variations of stacking Action Surge discussed by other players:

1 Eldritch Abomination (Source Volo’s Guide) is a spell that stacks multiple Eldridhs. However since there is no action necessary to cast Eridhs, it doesn’s stack with Action Force.
2 2 Tenser’s Fiendish Conjuring with the Action Surge Capacity, but it is unlikely because Tenser-Fiendish Conjuring**

The above examples show diverse strategies for stacking Action Force, but it is highly likely that the most comprehensive discussion of this topic relies on the specific situations from different players.

When Not to Stack Action Force

While your instincts might tell you this Action Force possibility will work, you simply must be aware of conditions under which it is restricted:

1. Breach of Spellcasting limitations
2. Different Actions (Action
   • Spontaneously casting
   • Other magical effects (Eradicating the Action * Action Force to Second Level, for an example of an issue Feared**
   • Divination (DDEX
   • Dark Magic (PHO)

Conclusion

In conclusion,
the stacking of Action Action with other abilities, has significant implications for game complexity. While it’s still an exciting feature, awareness of the limitations and exclusions is crucial to optimal usage.
