I - Rules
(see RTL, p. 31)
The Plot card “Brother Against Brother” is the only way to enslave a hero. Once a hero has been enslaved, the effect is permanent. From then on, at the start of the hero’s turn, the hero player must roll a black power die. On anything but a power surge, he may take his turn as normal. On a power surge, the Avatar’s mental powers take over the hero and he is controlled by the overlord player this turn. This effect is similar to the Dark Charm card, except that the overlord cannot force the hero to attack himself.
