Master's Libram

Master's Libram is a Hardmode summon weapon. It spawns one of six possible spell book minions that fly around and attack enemies by launching a corresponding spell projectile at enemies. By right-clicking, the player can alternate between the six possible spell books. Like other minions, these spell books are invincible and follow the player for an unlimited amount of time, unless the player dies, summons a replacement minion, or cancels the buff.
