The Black Otamatone is a Hardmode Bard weapon that is sold by the Tracker after completing the "Tracker's End" contract. On use, it creates a static otamatone projectile at the cursor's position; creating a second one within a distance of about 30 tiles forms a red chain between the two, damaging any enemy that comes into contact with it. Only two otamatone can be active at a time; attempting to create more will remove the older of the two projectiles.

Like other Black Weapons, it grants the Darkness Within buff, granting stacking damage for each hit before peaking at 50 stacks. After reaching 50 stacks, it will inflict the Wither debuff on hit enemies. When used, it empowers nearby players and the user with the Empowerment Prolongation III empowerment.

Its best modifier is Fabled.


  • It is recommended that you use any Black Weapons along with The Black Cane as the Darkness Within buff that it creates will stack, making it easier to get to 50 stacks.


  • Otamatone are Japanese electronic music synthesizers shaped like an eighth note. To play, one hand squeezes on the head to produce sound while the other controls the pitch by moving their finger along the Otamatone's stem.
