Vanquisher Arrows are craftable post-Moon Lord arrows that are made from Cosmilite Bars. Fired Vanquisher Arrows home in on enemies and pierce through tiles; additionally, airborne Vanquisher Arrows split into more Vanquisher Arrows as they travel through the air. The cloned Vanquisher Arrows do not home in on enemies and shortly dissipate after being spawned. Vanquisher Arrows inflict the God Slayer Inferno debuff onto any hit enemies.
- Cloned Vanquisher Arrows deal typeless damage. Therefore, they cannot inflict critical hits and are unaffected by Rage or Adrenaline.
- Due to how the arrows work, purposefully missing will deal more damage.
- Using Vanquisher Arrows with accessories that multiply projectiles, such as the Elemental Quiver, can lead to massive frame drops due to the sheer amount of projectiles created.
