A Stateless fighter can join any army. He is then considered to be an Ally (see p. 127). He integrates so well that he acquires the most common ability among his companions-in-arms. The number of fighters with this ability is used to determine which one it is, not their A.P. value.
If several abilities are equally common in the army, then the player controlling the Stateless fighter chooses one of them. If this ability is bound to a value, then the Stateless fighter gets the most common one.
Attention! The abilities marked with a * cannot be acquired by Stateless fighters.
