Bagpipe

The Bagpipe is a Hardmode Big instrument that is dropped by some enemies during Blood Moon event after the Wall of Flesh is defeated. It releases lines of orbs which explode with a 1 second delay, dealing damage to nearby enemies. While held, the Wind Timer will appear below the player; the weapon's effects vary based on whether or not the timer is over a marker when attacking, as well as how long the rhythm has been held. When used, it empowers nearby players and the user with the Resource Regeneration I empowerment.

Correctly attacking while the timer is over a marker will increase the weapon's damage by 4%, which stacks with successive correctly timed attacks up to 120% increased damage.
 * Once the bonus damage has reached 40%, the line will become longer and the bagpipe will empower nearby players and the user with the Resource Regeneration II empowerment.
 * Once the bonus damage has reached 80%, the line will become even longer and the bagpipe will empower nearby players and the user with the Resource Regeneration III empowerment.
