Blade Staff

The Blade Staff is an aerial melee Hardmode summon weapon that is dropped from Enchanted Swords. When summoned, a miniature Flying Knife spawns above your head and follows you around. When an enemy is nearby, it flies to the enemy and goes back and forth like a Stardust Dragon. It has relatively low damage, but ignores 25 enemy defense to make up for it.

Its best modifier is Demonic, Deadly, Mystic, or Hurtful: unlike most summon weapons, the Blade Staff has no knockback, thus it cannot get the Ruthless modifier. Due to its low base damage, all damage-improving modifiers improve its damage by the same amount.

Trivia

 * The Blade Staff has the lowest base damage out of all the minion summon weapons in the game, but the low damage is easily compensated by its ability to ignore 25 enemy defense.
 * While the summons of the staff have a similar appearance to the Flying Knife, it is not a drop from Hallowed Mimics, but the Enchanted Sword.
 * Along with the Stardust Dragon Staff and Raven Staff, the Blade Staff is one of 3 Following Minion-summoning items whose buff description is not "(Minion) will fight for you", instead being "Death by a thousand cuts".
 * "Death by a thousand cuts" was a torturing and execution method used in imperial China.
 * Altho it is stated that the weapon has "No Knockback" under effects of "Plenty Satisfied" it obtains "Extriemly weak knockback" which drastically increases it's effectiveness against stronger enemies since large amount of daggers can lock an enemy in place.
