The Blood Thorn is a Hardmode magic weapon that has a 12.5*1/8 (12.5%) chance of being dropped by the Hemogoblin Shark. When used, it summons penetrating Blood Thorn projectiles.

Its best modifier is Mythical.


  • Blood Thorn projectiles spawn from random solid blocks or platforms in a circle around the cursor. If a solid block obstructs line of sight between the player and the cursor, then projectiles are instead summoned from a circle around the obstruction point, facing the cursor.
  • If no solid blocks or platforms are in the thorn spawning circle, then thorns will instead spawn from a circle around the player.
  • If there are zero valid blocks for summoning thorns (i.e. the player is both in midair and targeting a point in midair) then thorns will be summoned from the player's hitbox.
  • Projectiles cannot be summoned from background blocks and actuated blocks.


  • The Ice Blocks summoned by the Ice Rod can serve as roots for the Blood Thorns.
