Ichor (debuff)

Ichor is a debuff that lowers the victim's defense by 20. It is inflicted by the Ichor Shower 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.

Tips

 * Because of its effect, it is useful even in late-game, since almost nothing has a resistance to it. It is especially useful against enemies with high defense (e.g Skeletron Prime (especially during head-spins), Paladins, 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

 * Despite inflicting the Ichor debuff, Ichor Stickers are not immune to it.
