This article is about the debuff. For the crafting material, see Ichor.

Ichor is a debuff that is inflicted by the ranged attack of an Ichor Sticker found in the Underground Crimson or by the Tainted Ghoul found in Crimson Underground Deserts in Hardmode. It can also be inflicted by weapons and the ammo crafted with Ichor. On  Desktop,  Console, and  Mobile, the debuff lowers the afflicted player's defense by 15, or adds 15 armor penetration when calculating damage against afflicted enemies. On  Old-gen console and 3DS, it lowers the afflicted entity's defense by 20.

Notes

• Enemies and players afflicted with Ichor are tinted golden. They will be visible in the dark but do not emit light.
• (Old-gen console and 3DS versions) Despite Ichor Stickers inflicting the Ichor debuff, they are not immune to the effect.
• (Old-gen console and 3DS versions) The debuff will not reduce an enemy's defense below 0.

Tips

• Because of its effect, Ichor is useful even in the late game, since very few enemies are resistant to it. It is especially useful against enemies with high defense (e.g. Skeletron Prime (especially during head-spins), Duke Fishron, etc.)
• A common tactic is to use an Ichor-inflicting weapon on an enemy, and then finish it off with the player's main weapon.

Trivia

• The damage increase from Ichor on the player changes depending on the world difficulty (Expert(Desktop, Console and Mobile versions)/Master Mode(Desktop, Console and Mobile versions)), due to how the effectiveness of defense changes with the difficulty.
