As a crafting reagent
Due to Demonsteel being created by combining Felslate and Leystone, it is possible the outcome is medium-weight but extremely resilient armor or weaponry. Felslate is naturally a very heavy metal, while Leystone is the opposite, thus balancing the weight. Yet both are sturdy materials, possibly combining their strength.
