Magical Harp

The Magical Harp is a Hardmode magic weapon that auto-fires slow, ricocheting, piercing projectiles that graphically resemble musical notes. It is the most mana efficient weapon in the game, but due to slow projectile speed and lack of knockback, it is only useful for certain enemies (such as The Destroyer) Each projectile lasts for about four seconds before dissipating, and will both ricochet and pierce enemies an unlimited number of times until this time limit is reached. Notes produce a reasonable amount of light, and are not affected by gravity.

The speed of each note can be controlled by clicking closer or further from the character: Closer clicks fire slower-moving notes, and further clicks fire faster notes. The speed at which each note travels does not affect their lifespan; all last about four seconds.

The sound played upon firing resembles a plucked string, with its pitch correlating to the firing speed: Slower firings playing lower-pitched sounds, and faster firings playing higher-pitched sounds.

The Magical Harp is unable to acquire the Mythical Modifier, nor any other modifier that affects knockback. The best modifiers for this weapon are Mystic or Demonic.

Tips

 * The Magical Harp is powerful due to its low Mana cost and ability to pierce and ricochet an unlimited number of times for the four-second lifespan of each note. In small spaces, or with clusters of enemies, or with large enemies, notes continue slicing through enemies until they dissipate, for an unmatched level of continuous damage.
 * The Magical Harp is generally considered the quickest way to kill The Destroyer. It can reportedly do so in less than 20 seconds, if a Magic Power Potion is used.
 * Low, slow notes can hit large enemies multiple times, while fast, high notes are more likely to hit moving targets.
 * Being able to bounce off walls allows it to be effectively used in small spaces.

Trivia

 * The harp's sprite is always shown while equipped, unlike most weapons that only show while firing.
