Gunjurer

Summons 6 bullets, during which time any bullets fired at it will be captured. The 6 bullets along with any absorbed bullets are then fired at the player. Occasionally disappears and reappears elsewhere in the room. It cannot capture any melee attacks (e.g. Blasphemy's slice), beam weapons' beams, the final shot of the Finished Gun, or shots fired by Gunther. If killed before it has finished casting, it will scatter its bullets in random directions.

Apprentice Gunjurer
Fires bullets in a variety of rotating shapes, such as a square, a circle, a triangle, or an X. Occasionally disappears and reappears elsewhere in the room.

High Gunjurer
Fires a massive ring of bullets at the player. Occasionally disappears and reappears elsewhere in the room.

Lore Gunjurer

 * Warrior: The bullet will home in on the player until it vanishes.
 * Rogue: The bullet will home in on the player and then teleport behind them in an attempt to catch them off-guard.
 * Mage: The bullet follows the player closely and will shoot 3 smaller bullets until proceeding to home in on the player until it vanishes.
 * Bard: The bullet will home in on the player, bouncing off of walls until it vanishes.

Trivia

 * The Apprentice Gunjurer's attacks are a reference to the shapes on the buttons of the PlayStation DualShock controller.
 * Gunjurers may be a reference to the Magikoopa from the Super Mario series. This is seen in their similar cloaked appearance, and the apprentice's bullet clusters having a striking resemblance to the Magikoopa's projectile attack.
 * Gunjurers also bear incredible resemblance to Shy Guys (also from the Super Mario series)
 * In one of the Resourceful Rat's attacks, he is shown to be using a captive Gunjurer to preform the attack.
 * The Gunjurer's ammonomicon description is likely a reference to Final Fantasy.
