So great is Clan Eshin's training in the art of stealth that they are fully capable of launching a successful assault in the dead of night. Often the first sign of their presence is when their prey begin to die. Any Clan Eshin army which consists entirely of skirmishers and character models may impose the following rule:

At the start of each game turn, roll an Artillery dice and multiply the result by 3 to find out how far in inches the troops can see through the darkness. If you roll a Misfire then the moon is bright enough for normal warfare for that game turn. You cannot shoot, charge or cast spells at targets you cannot see.
