Harmonizer
Shaping and refashioning sound are the craft of the Harmonizer specialty. While many are remarkable musicians, they prefer to use musical instruments as catalysts for manipulating sound waves.

Musical Training
3rd-level Harmonizer feature
You gain proficiency in Performance and three musical instruments of your choice. You can use a musical instrument as a spellcasting focus the same way you can an artisan’s tool.
Harmonizer Spells
3rd-level Harmonizer feature
You always have certain spells prepared after you reach particular levels in this class, as shown in the Harmonizer Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.
Each spell is in the Player’s Handbook, unless it has an asterisk (a spell in Xanathar’s Guide to Everything) or a dagger (a spell in Aronar’s Grimoire).

Alter Sound
3rd-level Harmonizer feature
You are able to manipulate sounds. As an action, you can choose one sound you can hear such as the rustling of the wind or your voice and alter it in the any of following ways:
- Transform the sound into a different sound of your choice.
- Alter the volume of the sound, such that a shout becomes a whisper or a sigh becomes a thunder.
- Change spoken words into different words. A speaker most likely will stop speaking once it realizes the words coming from its mouth aren’t its own.
- Duplicate the sound such that it also originates in a second place of your choice.
The volume the altered sound can occupy can exceed a space no greater than a 300-foot radius centered at point you can see. This effect can last up to 10 minutes, but must use your action each turn to maintain the change in the sound, and can only manipulate a single sound at a time. You can’t deal or prevent damage with this feature.
You can use this feature a number of times equal to your Intelligence modifier (minimum of once) and regain all expended uses when you finish a long rest.
Thunderous Might
5th-level Harmonizer feature
When you cast a spell of 1st-level or higher that deals thunder damage, you roll 2d8 and you gain a bonus to one of the spell’s damage rolls equal to the number rolled.
Sonic Field
9th-level Harmonizer feature
Your ability to manipulate sound increases,, granting you the following benefits:
- You can alter up to three sounds at once using your Alter Sound feature, and you can choose to alter a different sound each time you use your action to maintain it. Sounds you no longer control return to normal immediately.
- You have advantage on spell attack rolls that deal thunder damage.
- Creatures have disadvantage on saving throws against your effects that deal thunder damage.
- When you deal thunder damage to an unattended object, it takes the maximum damage.
Reactive Silence
15th-level Harmonizer feature
You have resistance to thunder damage.
In addition, you can dampen and nullify sounds reactively. When thunder damage is dealt, you can use your reaction and expend one use of your Alter Sound feature to grant each creature you choose within 300 feet of you immunity to thunder damage until the start of your next turn. Creatures that gain this immunity are treated as if under the effects of the silence spell during this time.
