Battalion's Baton

This baton is designed to look exactly like a conductor's baton.

As a bonus action, one may begin conducting with the baton, causing an aura of symphonic music to fly from the baton. Until the start of the wielder's next turn, all friendly creatures within 10 feet of the wielder that can hear the music can choose to use a 10 in place of the die's actual roll when making an attack roll or Charisma (Performance) check.

Once the wielder's next turn begins, the symphony ends and the baton becomes a regular nonmagical conductor's baton.
