In Dungeons & Dragons, a bard is a special type of character that uses music and storytelling to fight monsters and support their friends. They are a bit like a combination of a musician and a wizard.
They have a special ability called "bardic inspiration," which means they can sing a song or tell a story to make their allies stronger or more skilled in battle. They also have other spells and abilities that let them control crowds or buff their allies.
Bards can use a variety of musical instruments to perform, like guitars, flutes, or even their own voice. They can also learn different skills like sneaking, picking locks, or talking to animals.
So basically, bards are like magical musicians who use their music to help their friends and defeat enemies.
