The Anti-materiel Rifle is a craftable post-Moon Lord gun. It fires a high-damage High Velocity Bullet, if Musket Balls are used as ammo. If the first bullet critically strikes an enemy, a second swarm of bullets will fly towards the enemy's position from the left side of the screen regardless if the enemy died or not. Holding right click will use its zoom ability, which scrolls the viewing area of the screen in the direction of the cursor in a fashion similar to the Sniper Rifle. Bullets other than Musket Balls are shot as normal, along with a 130% damage multiplier.

This weapon's bullets inflict the Marked debuff onto enemies, decreasing their damage reduction by 50%; in addition, it will also permanently reduce an enemy's defense by 25, which cannot stack with itself.

Its best modifier is Unreal.

  • If used in conjunction with the set bonus of Silva armor, it is possible to massively heal upon shooting an enemy.
    • However, the Silva armor set is geared towards mages and summoners, so this is not very practical.
  • It is recommended to focus on boosting your critical strike chance while using the Anti-materiel Rifle, as critical strikes will greatly increase its DPS.


  • In real life, an anti-materiel rifle is a rifle that is designed for use against military equipment (or "materiel" in military terminology), rather than against other combatants ("anti-personnel").
