Ichor (debuff)

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

Ichor is a debuff that lowers the afflicted entity's defense by 15 / 20. It 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 Old-gen console, Windows Phone, Old Chinese, 3DS , and tModLoader Legacy versions, despite Ichor Stickers inflicting the Ichor debuff, they are not immune to the effect.
Enemies and player afflicted with Ichor are tinted golden and will still be visible in the dark but does not emit light.
The debuff will not reduce an enemy's defense below 0.

Because of its effect, it is useful even in late-game, since barely any 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.
Ichor stacks with and can be used alongside Betsy's Wrath for a huge reduction of defense against the vast majority of enemies and bosses, as very few enemies are immune to Ichor or the Betsy's Curse debuff. The combination leaves most enemies and bosses entirely without defense.

The damage increase from Ichor on the player changes depending on the difficulty; It will increase the effective damage by 8 in Classic, 11 in Expert, and 15 in Master Mode. This is due to how the effectiveness of defense changes with the difficulty, getting stronger as it gets harder.
