Marsh oozes, also known as marsh slimes, are sleek blobs of slime with pseudopods and acidic skin. Oozes can be found in the ancient kingdom of Kasmarkin, where they exclusively occupy the slime-covered Fortress of Taug. Oozes produce black pearls, which makes them particularly useful to the Crystalism-using Magi; it is rumoured, however, that these oozes also serve a greater purpose, one that can put to use by all adventurers, provided they can decipher what it is.
