Garyogle Sludge

Gargoyle Sludge is a material in the biome Cataclysmic which is in the floating island, Caverns of silence, if you attack it it will spawn the Vex Basilisk and can the Amalgamte Sludge from it can be used to craft the Vex Scythes (yes I know, one evil biome per world so yes it will be harder like the veins from the ????? so you have to atleast make 2 worlds to make it!), in War Mode it causes rifts to spawn in the Venire Room.
