1- Obsydian Shackles : 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.
Can the Overlord, while he is playing the hero's turn, drink one potion, use one-time use item and spend rumors card he kept for the FInal Battle?
2- Can the heroes put a rest order on themselves while going through the portal between donjons?
3- Expulsion : Are heroes expulsed when the Overlord kill them all in one turn? Can the Heroes be expulsed in the Final Donjon?
4- Rapid Fire : Can a Heroes use Rapid Fire with the attack he made with the Guard order?
5- Transport Gem : Can the overlord use this card during the Heroes Turn like he does with Big Troubles?
Thanks for the anwers
