Rarity: N/A (You can decide)
Fire mode: Very short windup (opening the book) before firing projectiles automatically in about a 60 degree range.
Damage: N/A (You can decide again)
How projectiles are supposed to work: Fires them in order from top projectile down (Supposed to spell "BAM" in ancient latin letters, sorry if it's wrong)
Possible in-game description: "A book detailing the lore of the Gungeon. It is assumed that the Gundead read it in their spare time. It is sometimes confused with the Booklets of the Gungeon, leading to a less-than-desirable outcome."
My first time at sprite art; it shows. You can change whatever you want about it, if you please. Thanks!
