The Ballista is a craftable Hardmode bow that auto-fires. The arrows can pierce one enemy and shatter into fossil shards upon hitting a second, as well as upon hitting solid blocks. Fossil shards deal 20% of the weapon's base damage. All projectiles will inflict the Armor Crunch debuff.

Its best modifier is Unreal.



Used in[]


  • The Magic Quiver increases the damage of the arrows shot by The Ballista, but doesn't increase the speed.
  • The Ballista nets massive damage output against large ground-based enemies such as Astrum Aureus when fired at from above, due to both the arrows and the shrapnel all hitting the target.
