Golgfag’s Maneaters always have the Stubborn and Vanguard special rules from the Been There, Done That rule. In addition, when included in an alliance, they are treated as trusted allies by all units on their side, and count all units on their side as trusted allies in return. If an army includes Golgfag’s Maneaters, then Golgfag must set up with the unit, and may not leave it. No other character may join the unit.
Note: If Golgfag is taken, then one unit of Maneaters in your army may be upgraded to Golgfag’s Maneaters at no additional points.
