Ichor Sticker

Ichor Stickers are Hardmode enemies that spawn in the Underground Crimson. They float around in the air. When tracking a player, they spit Ichor at them, which shoots several blocks and is affected by gravity. Their spit can inflict the Ichor Debuff, lowering the player's defense by 20. Upon death, they will also drop Ichor. They are immune to the Poisoned and Venom debuffs.

Tips

 * To easily farm Ichor, it is recommended for the player to create horizontal shafts in the Underground Crimson for the Ichor Sticker to spawn. A three block tall shaft will cause the Ichor Sticker to become stuck and barely able to shoot the player (as they shoot in an arc); with a four block tall shaft, they become mobile but will still have problems shooting the player. You will also have more room to deal with the irritating Floaty Gross, which can fly through blocks.
 * They appear to sink in any liquids they enter and can be effectively immobilized by water that is at least 4 blocks deep. While this will not prevent them from shooting if you are in sight, they can be easily dealt with using nearly any weapon available at the start of hardmode (besides pearlwood weapons).
