The Purple Mucos is a dye material that is dropped by Sea Snails, which only spawn in the Ocean biome. Its sole purpose is to make Purple Dye.
- Mucos (as it is spelled in-game) is a misspelling of mucus.
- Though already a liquid, it cannot be used as a dye until you craft Purple Dye with it.
- The ancient Phoenicians used murex (a species of snail) to make purple dye, which was often worth its weight in silver.
- One of the best ways to farm sea snails is by using a Solar Tablet as soon as the sun rises, since during the Solar Eclipse, the enemy spawn rate is highly increased (almost as during a Blood Moon, but the latter can't be manually summoned). The key factor from this method is that Solar Eclipse enemies can't spawn in water, only being able to spawn in the nearby beach or any cave below the sea, and they rarely come to the ocean water. Most of the time, you'll only fight the regular ocean enemies with a increased spawn rate, and only very occasionally encounter a Eclipse enemy.
