Wintercrest: Fragments of Fate
Exotic elemental material
Entropic ooze is a strange material that acts like all elements and none at the same time. It reacts to contact with elements by producing an equivalent amount of the opposing element. For example, in the presence of wind, it develops earthy dust on the exposed surface. Water causes it to produce flame, and vice versa.
Rufian dissolved into entropic ooze when defeated.
