"Harmonic was designed to help bards utilize their bardic abilities during melee combat. Though most bards enjoy staying out of melee action, preferring to enhance and cheer on their friends from a distance, there are those who enjoy getting into the middle of the action.
Harmonic allows bards to utilize their known spells during melee combat without using a spell slot. The drawbacks are the bard must be in melee combat, and they must successfully hit their target with the harmonic weapon. In addition, these weapons have limited charges. Using the last charge may result in the weapon vanishing from their hand during combat.
Several versions of this weapon have been created to allow bards with enough coin to purchase a greater powered Harmonic.
The pricing reflects the availability of the item. Not many bards wish to sell their harmonic weapon, and quantities are limited."
