A hand drum that was built using the wing flesh and heart sinew of Thresheract The Scorned. When played the sound of the drum resonates deep into the soul of those close enough to hear it making their adrenaline surge as they become overwhelmed with a strange astral power.

As an action, you can play this drum to give all allies within 20 feet of you advantage on their next roll. If the drum is played as a bonus action, the effect's radius is moved down to 10 feet. 

This drum can be played 3 times per long rest before the drum head and sinew need to be tightened again. 

Notes: Item must be put together by a bard and played for 1 hour before being able to unlock it's full potential.
