Shanty Shiv

Weapon (dagger), rare

This thin-bladed weapon is a +1 dagger that hums menacing pirate war chants, mournful dirges of loss, and muttered imprecations with every stroke, granting advantage on any Charisma (Intimidate) skill check.

If you have the Bardic Inspiration class feature, you can make a DC 15 Charisma (Performance) skill check as part of your bonus action. If you succeed, the melee attacks of those you inspire do an additional 1d4 psychic damage. This damage is increased by 1 for each 5 points you beat the skill check DC by.

In addition, you may make a DC 15 Charisma (Performance) skill check as a bonus action to change shanty shiv’s tune to bawdy ballads and jaunty jigs granting allies within 60-feet of you advantage on saving throws against fear effects.
