Once more unto the strangeness of LARP. Various things have codes, in this case the sand bags representing metal ores are all tagged with lammies and symbols to indicate which metal ore it is. Only people with the appropriate skill are issued with lore sheets to translate these symbols and those people know which are the best bags to take. This basically ends up with people pulling out A5 printed pieces of paper to figure it out. I thought it would be nice if these were wooden slats with the same information, much more in keeping with the setting.
