Unleashing the Power of Thunderwave in D&D 5e: A Comprehensive Guide

What does Thunderwave do in D&D? Thunderwave is a 1st-level evocation spell in Dungeons & Dragons 5th Edition (5e) that unleashes a powerful burst of thunderous force. The spell manifests as a wave emanating from the caster, impacting a 15-foot cube originating from the caster’s position. Creatures within this cube must make a Constitution saving throw. On a failed save, a creature takes 2d8 thunder damage and is pushed 10 feet away from the caster. On a successful save, the creature takes half as much damage and is not pushed. This makes Thunderwave a versatile spell for both damage and battlefield control. The area of effect, the ability to push enemies away, and the varying damage based on saving throws makes it an interesting option for many spellcasting classes. While not a consistent damage dealing powerhouse, it excels at crowd control and creating space.

Understanding the Mechanics of Thunderwave

The core function of Thunderwave lies in its ability to deliver both damage and forced movement. The area of effect is crucial, as it’s not a traditional cone or circle, but rather a 15-foot cube. This cube is generated from the caster’s space, which allows for tactical positioning. Furthermore, the Constitution saving throw is the gatekeeper for the full brunt of the damage and push effect. Creatures with higher Constitution scores are more likely to succeed, reducing the damage and negating the push.

The Role of the Caster

The caster is the point of origin for the cube, but surprisingly, the caster is not affected by their own Thunderwave. The Player’s Handbook explicitly states that the origin point of a spell is not affected, therefore the caster can even be in the center of the cube without taking damage from their own spell. This provides a valuable benefit, as the caster can freely use Thunderwave in close quarters. This ability allows for creative use of the spell to control the battlefield and create opportunities for other actions or escapes.

Upcasting Thunderwave

While a 1st-level spell, Thunderwave can be upcast using higher spell slots. This increases its power, with the damage dice increasing to 3d8 at 2nd-level spell slot, 4d8 at 3rd level and so on. This upcasting scales its damage, making it more relevant at higher levels, even if the area of effect does not change. This feature makes it an appealing option even as the character progresses.

Thunderwave’s Utility in Combat

The versatility of Thunderwave stems from its dual nature: damage and battlefield manipulation. Here’s how it can be effectively used in combat:

• Crowd Control: Pushing multiple enemies away with a single spell can disrupt enemy formations and create space for allies. This is particularly useful in tight corridors or when facing numerous opponents.

• Breaking Grapples: As the spell pushes creatures, it will immediately end a grapple situation if it pushes either the grappled or the grappling creature out of the reach of the other. This can be crucial for escaping from a dangerous hold.

• Tactical Positioning: The ability to push enemies into environmental hazards, such as pits or ledges, can provide an extra advantage. This allows the caster to shape the battlefield to their benefit.

• Creating Escape Routes: By pushing enemies away, a spellcaster can create an opportunity to disengage from melee combat and retreat to a safer distance. This is invaluable for classes that are not designed for close combat.

Frequently Asked Questions (FAQs) about Thunderwave

1. What level is Thunderwave in D&D 5e?

Thunderwave is a 1st-level spell. While it’s a 1st level spell, it can be upcast, but it is only available to classes that have spellcasting, such as Sorcerer, Wizard, Cleric, Bard and Warlock.

2. What is the shape of Thunderwave’s area of effect?

The area of effect for Thunderwave is a 15-foot cube, originating from the caster’s space. It’s important to understand that this is not a circle or cone, but a three-dimensional cube.

3. Can you hit yourself with Thunderwave?

Yes, the caster can include themselves in the 15-foot cube area of effect, but the caster is not affected by the damage or push of Thunderwave. The origin point of the spell is not affected.

4. Does Thunderwave damage the caster?

No, Thunderwave does not damage the caster. The spell specifically states that the origin point is not affected, and the caster can freely be in the area of effect without consequence.

5. Is Thunderwave worth keeping at higher levels?

Thunderwave’s effectiveness tapers off at higher levels compared to spells that deal higher damage with bigger area of effects. However, it can still be useful for its forced movement and potential crowd control, especially when upcast with higher spell slots, though other spells might be considered more effective.

6. Is Thunderwave a good move?

Thunderwave is a good move in the sense that it’s a very flexible spell, having crowd control and a good, but not great, amount of damage. Its main selling point lies in disrupting enemy formations and breaking grapples. It might not be ideal as a primary source of damage.

7. Does Thunderwave end a grapple?

Yes, the grapple condition ends if a creature is pushed out of range of the grappler or grappling effect. This makes Thunderwave an effective way to end a grapple in a pinch, or to break your ally free.

8. Do you have to roll for Thunderwave per target?

No. Since Thunderwave is an AoE, it affects all targets simultaneously. You only need to roll one attack to determine the total damage and effect for the targets caught in the cube, and then it’s each creatures individual saving throw that determines the rest.

9. Does Thunderwave work with spell absorption abilities?

Thunderwave’s damage is thunder damage, so anything that absorbs thunder damage will work on Thunderwave. If a creature is immune to thunder damage, it will not be harmed by Thunderwave but will still be pushed.

10. Can you cast Thunderwave while grappled?

Yes, you can cast Thunderwave while grappled, and if the grapple doesn’t prevent spell casting, your own cast of Thunderwave will end the grapple on you if it pushes you.

11. What can make Thunderwave more effective?

Thunderwave’s effectiveness can be enhanced through tactical positioning to maximize the push effect, exploiting environmental hazards. A class feature that boosts your spell save DC, will also help ensure that the enemies fail their saves. Upcasting is also a viable option, especially when a class is limited on its options.

12. Is Thunderwave a good option for damage?

Thunderwave is not a top-tier damage spell. While it deals a decent amount of damage, it does not surpass other damage-focused spells, especially at higher levels. However, it’s a good source of burst damage and the ability to push targets makes it a great utility spell.

13. When is Thunderwave most useful in D&D?

Thunderwave is most useful when dealing with clusters of enemies in enclosed spaces where pushing them can disrupt formations or even place them in environmental hazards. Additionally it’s a solid option when you or your allies are grappled.

14. Are there any class-specific benefits for Thunderwave?

While no class-specific mechanics, a Storm Sorcerer can use their class feature, tempestuous magic, to disengage and then cast a Thunderwave in the same turn, which can provide an extra tactical option.

15. How does Thunderwave interact with enemy positioning?

Thunderwave is designed to manipulate enemy positioning through forced movement, breaking grapples and creating space. This allows a player to create beneficial scenarios in a pinch, especially if they’re struggling with melee fighters.

Conclusion

Thunderwave is a versatile 1st-level spell in D&D 5e, providing both damage and battlefield control. Its ability to push enemies away and disrupt formations makes it a valuable tool in various combat scenarios. While its damage output might not be the highest, its utility makes it a spell worth considering for spellcasting characters. Understanding its mechanics and limitations will allow players to maximize its effectiveness and unleash its thunderous power to their advantage.
