Harmonic Channeler

Harmonic Channelers are sorcerers who have mastered the manipulation of wavelengths, soundwaves, and radiant energy. They possess the ability to harness these forces to devastating effect, combining force, psychic, and radiant damage in their spellcasting.

Resonant Attunement

At 1st level, you gain proficiency in the Arcana skill. Additionally, you can use your action to perceive the vibrations and soundwaves within 60 feet of you. This ability grants you advantage on Investigation or Perception checks related to detecting hidden or secret passages, as well as identifying creatures that rely on echolocation or similar abilities.

Wave Manipulation

Starting at 1st level, you gain the ability to manipulate and shape vibrational energy. You learn the Resonant Bolt cantrip, which allows you to send forth a concentrated wave of force, dealing force damage to a target within range.

Resonant Harmonies

At 6th level, you learn to blend and amplify the harmonies of different wavelengths and soundwaves. When you cast a spell that deals force, psychic, or radiant damage, you can choose to deal an additional 1d6 damage of one of those damage types.

Dissonant Manipulation

Beginning at 14th level, you can manipulate soundwaves and wavelengths in a dissonant manner to disrupt the thoughts of your enemies. As an action, you can force a creature within 30 feet of you to make an Intelligence saving throw against your spell save DC. On a failed save, the target takes psychic damage equal to your sorcerer level and is stunned until the end of its next turn. On a successful save, the target takes half damage and isn't stunned. Once you use this feature, you can't use it again until you finish a long rest.

Harmonic Mastery

At 18th level, your command over wavelengths and soundwaves reaches its zenith. When you cast a spell that deals force, psychic, or radiant damage, you can choose to maximize the damage instead of rolling for it.
