Huge elder scrolls fan and I love the concept of Glass weapons and armor as seen in the games (particularly oblivion).

I'm fairly sure the idea came from the AD&D spell "Glass-Steel" which is unsurprisingly absent from Hyperborea. For my table I've reproduced the glass-steel spell, allowing the creation of ultra-lightweight +1 plate mail (classed as medium armor) and +1 weapons. does this seem too powerful for a 6th level wizard spell? the actual crafting requires the skills of a glassblower/glazer in addition to rare components (per alchemy) and the ability to cast the spell.

I've also brewed a special glass helm as a reference to the waterlogged "Fingleam" found at the bottom of the sea off the coast of Anvil in  TES 4.
