Used enchant adamantite on a brick without blue diamond, got error message, but
 

Napyt gave me an adamantite brick to enchant. I've never used the spell before so didn't know a blue diamond was also a reagaent

He handed me 7 bricks, I cast the spell, got an error of missing reagent: blue diamond, but only had 6 bricks
