Plectrum of Power (Fabled)

This wooden plectrum is painted red and black and bears a leering devil's head with glowing yellow eyes. It gives off a small jolt of energy when touched, like static electricity. A worshiper of Asmodeus can use it as a Holy Symbol, and a Bard can use it as a spellcasting focus.

The spell Detect Evil and Good, a Paladin's Divine Sense, and other similar effects sense this item as if it were a Fiend, and indeed it was created from the essense of a powerful devil.

Distortion. When using this plectrum to play a stringed instrument, you can make the music extra loud and amplifed with distortion such as fuzz, reverb, and sustain.

Attuned Abilities
