Strummer (5e Equipment)

Weapon (longblade), rare (requires attunement by a bard)

A blade of soft hewn gold, a split down the middle revealing innumerable strings. They always hum, even when untouched, and release melodies when in active use. You have a +1 to attack rolls with this weapon, and it also has the finesse property.

Strummer counts as a bardic focus, and when you cast a spell using it, the next attack you make with it within the minute deals 1d4 extra thunder damage.
