Previous mines were laid by individual legions and ONLY the legion
laying the mine would be immune to its effects (apart from a very very
minor chance of accident). This has been changed. NOW it is
assumed that a legion loyal to a particular city or guild will be
informing all other legions from that city or guild of mines laid,
so its fellows will also not set them off. Thus, if a Parrian legion lays
mines, all other Parrian legions will know whereabouts. Likewise, if
a Mages Guild legion lays mines, all other Mages Guild legions will
know their whereabouts.
Take note!
