@KOgaming OOC says you need 10 units for a sword and 5 for a scabbard. Scabbard is obligatory for the challenge.
Ain't it a bit jerkish to take more than you need on this kind of challenge?
You won't have to worry about resources too much, I've calculated it's roughly enough for about 12 swords so as long as everyone takes just the amount they need it'll work out, but if we actually run out I'll add some extra materials because that'd be my fault for not calculating it well enough ^^;
@KoL
You forget we can steal from other people's forges. Barring taking their sword from under their noses, and out right murder, I imagine taking a few ingots from the person who took 50 wouldn't be remiss.
