Can Curufin find some explosives somewhere and actually blow up a building or two?

He manufactured some blasting powder from scratch in his last game, and he probably wasn't unfamiliar with the stuff even in his canon world. Feanorian smiths mined their own metals and fuels. They may have known how to blast rock as well as dig it. So if there's none already concocted and immediately available, he could whip up a bunch of boom powder on his own, if he could find the right materials. XD
