Okay, I cannot, for the life of me, remember how big or how much one unit of the stuff weighs. Any cannon info? I don't have my stuff with me, as I'm at work, so...yeah.

MitS says 10 grams.

Hey, thanks Lilt.

Note, that's for Synthetic, not Natural orichalcum.

Well. A single unit of refined orichalcum still only weighs 10 grams, but you get it as un-refined first which weighs 20 grams.

Units of natural orichalcum are also only half as effective, so you need to use twice as many units to get the same effect, doubbling the effective weight per unit (compared to synthetic orichalcum) to 20 grams.

Right on.
