Banshee Hook

The Banshee Hook is a post-Moon Lord spear dropped by Polterghast. It is swung in front of the player at an odd angle, similarly to the Ghastly Glaive, and releases a line of five projectiles at once. Hitting an enemy directly with the weapon causes a ghostly explosion, dealing rapid damage. Its projectiles go through blocks, ignore immunity frames, pierce two enemies before disappearing upon hitting a third, and will slow to a stop some distance away if uninterrupted.
