It is unknown whether the thing known as Defiler is a variant of the ordinary slime or if it is the elder form of the said creature. Although they share numerous characteristics, the Defiler is by far more powerful and dangerous. Since the Defiler is often found accompanied by some kind of demon, it is theorised that the greater slime is possibly not even native to our world. It is assumed that some life form brought it here from the demons' realm of existence. Still, just like the common slimes, it shares the love for humid places of decay and darkness and like its smaller variant it does not care about living or dead as long as it is organic when it comes to eating habits. When the slime is seen as a symbol of poison and decay, those characteristics cannot be overlooked in the Defiler. Its relation to poison and decay also becomes evident in its attributes. A choking stench surrounds the Defiler and it can shoot some parts of itself to infect its victims with poison and decay.
