Crumbly stuff

Crumbly stuff is an ore found while playing the Fremennik saga, Thok It To 'Em. It has the same appearance as Promethium ore. It is used as a side objective item, and is "mined", via headbutting, from a promethium rock, and is used in the furnace as an attempt for Thok to try and make a new sword. However, since he does not know how to smelt, he simply dumps all the crumbly stuff into the furnace and is unable to retrieve it.
