Where Umor consists of water, Umbracrua consists of blood. Since blood is 90% water, there is no material difference between the two liquids. Before the formation of The Rigaborum there where no rules against “blood magic” i.e. Riga-manipulation of the blood of living creatures. Just like Umor, Umbracrua is infused with fine-grained Wolf Steel™ granulate. KDIS can solidify the Umcracrua.
