Ichor Bullets in action.

The Ichor Bullet is a type of Hardmode bullet used as ammunition by guns. Ichor Bullets inflict the Ichor debuff onto enemies for 10 seconds, decreasing the enemy's defense by (Desktop, Console and Mobile versions) 15 / (Old-gen console and 3DS versions) 20 points, which effectively can increase the damage from the bullet by up to (Desktop, Console and Mobile versions) 8 / (Old-gen console and 3DS versions) 10 from its base value of 13, totaling the effective damage up to (Desktop, Console and Mobile versions) 21 / (Old-gen console and 3DS versions) 23. They are the Crimson counterpart to the Corruption's Cursed Bullets.

  • When fighting bosses, it is advantageous to keep some of this ammo in the ammo slots, as it allows the player to switch between using Ichor Bullets to inflict Ichor and using other bullets to deal more damage. It is not recommended to use this ammo by itself, since other types (most notably Crystal Bullets) can inflict significantly more damage with the Ichor debuff applied.
  • The Destroyer, the Lunatic Cultist(Desktop, Console and Mobile versions) and all Celestial Pillars(Desktop, Console and Mobile versions) are immune to the Ichor debuff, making this ammunition mostly useless against them.
  • (Desktop, Console and Mobile versions) Ichor Bullets reflected by Mimics in Expert Mode do not inflict the Ichor debuff on the player.
  • In a PvP scenario, the damage increase from Ichor actually changes depending on the difficulty: on Journey/Classic it will increase the effective damage by 10, 15 on Expert, and 20 on Master mode. This is due to how the effectiveness of defense changes with the difficulty, getting stronger as it gets harder.
